There are a lot of benefits of controlling your air conditioner from your smartphone. The main advantage is that you can set the right temperature before arriving home. By doing this, the moment you enter your home you will find that the temperature is exactly how you wanted it.

Furthermore, you will be able to turn off your air conditioner if you forgot about it when you left home. Also, you can control when you are in other rooms of the house where you cannot control it directly with the remote. Similarly, if you are lying in bed and want to warm up the lounge, you can! You can even customize the power of your unit to save energy.

Another great advantage is that you can control your air conditioning in situations where your aircon control doesn’t work properly. Also, you won’t have to remember what the settings are that you like the most when it comes to temperature control – in the app, you can save these parameters and access the temperature you like with just one click.

In this article we will discuss several apps that can help you control your air conditioner in the best way possible. Also some of them include other features that can be helpful when it comes to comfort and utility.

Air conditioner remote control apps

In the Play Store or App Store, many remote control apps work with many different devices. You just have to make sure the app you want to download is supported by your phone. Also you need to make sure that your brand of air conditioner is compatible with the specific app. After making sure of those two things, you can start downloading the app.

1. ASmart Remote IR App

Asmart App

The first app we will show you is called ASmart Remote IR. It is compatible with the most popular brands of air conditioners and it is very easy to use. The first thing you have to do after installing is clicking on the “+” button to add a new device and select the air conditioning brand you have.

The functions you have are turn on, turn off, increase, or decrease the temperature. Also, you can save your settings for quick access to the temperature you like the most. Furthermore, you can use this app with other appliances in your house.

2. Tado Smart Air Conditioner App

Tado Air Conditioning App

The Tado Smart Air Conditioner App helps you control your heating devices as well as your air conditioner easier than ever. This app helps you make your home air conditioner more intuitive. It can connect using an infrared connection which helps you even connect with old air conditioners.

This app works based on your preferred settings. So this means you can turn it off when nobody’s home, lower the fan setting, or even put it in quiet mode. Also, it acts as a remote control for your air conditioner, which means that you can change the temperature from your bed or your couch without having to stand up.

3. AirTouch

AirTouch Air Conditioning App

The AirTouch app is not only a remote control but it has a monitoring system that will help you manage your home’s temperature in the best way possible.

It will help you turn your air conditioner on and off, change and monitor setpoint temperatures, use alerts to know when to perform specific actions, change your aircon from heat, cool, fan, or automatic (if it has these options) and control from 1 to 4 air conditioners.

This app is one of the most complete ones out in the market. Also it is really easy to set up and understand. However, it does require AirTouch components being installed as part of your air conditioning and/or zoning system.

4. Cielo Home – Smart AC App

The final app on this list is the Ambi Climate app. The best feature of the Ambi Climate App is that it has a great ability to record all the actions that you perform with your air conditioner. Also, it analyses and acts on the information you give to the app.

In this way, this app will know and internalise the settings that you like the most and will build a profile based on your habits and preferences. So, it mainly saves you time by knowing what air conditioner settings you prefer according to the outside climate, the day, and the time.

Also, you can use this app to set specific levels of temperature and humidity when you are not home.  This keeps things under control, ready for your return home.

Remember that when you use an app for your air conditioner you can save a lot of money from energy usage. This is because when you leave your air conditioner running after you leave home there is nothing you can do about it. This situation represents a waste of energy, and therefore money.

On the other hand, if you have an app where you can control your air conditioner from wherever you are, then it is easy to turn off your air conditioner when you are not home.

At this point, you may be wondering if having any of these apps is worth it. The answer is yes. You have seen all the advantages they have, so do not discard the idea of downloading any of these apps without considering them first.

You need to know that all of these apps are different because they solve slightly different problems, and they execute their functions differently. So, it is up to you to decide which one works best for your needs.

Most people think that to save money they have to build a smaller house or use cheaper materials. However, the truth is that the real savings can be seen in the long term and you can take action from the very beginning.

Throughout the useful life of a home, there are many expenses from month to month, quarter to quarter, that you will have to pay. These include the cost of heating, air conditioning, water consumption, and electricity. The main problem with conventional houses is that they are built without taking energy efficiency into consideration.

There are several reasons why you should think about building an energy-efficient house. For example, you will save money as you use less energy and you will also be helping the environment as you will minimize power consumption.

In this article, we invite you to discover 5 key elements that will allow you to know how to design or choose an energy-efficient house.

Strategic orientation

Designing and/or choosing a good orientation is key to start with for an energy efficient home. The house should follow a northern orientation in the southern hemispheres and a southern orientation in the northern hemisphere.

It is also important to take into account the weather of the place where you are going to live. Based on that, you must decide on a suitable size for the windows and see if you can take advantage of existing trees or other resources to keep the house cooler by shading.

Also, the design strategy for optimal orientation of the house will depend on the land and its size. You must not forget to establish where the main facade of the house will be as it should be optimal.

Thermal insulation

It is important to use materials with high thermal resistance in the home. Building materials need to have good thermal insulation as this is key to avoid energy losses.

Thermal resistance is the ability of a material to establish a barrier to the passage of heat from inside and outside the house. This material will naturally assist with indoor temperature retention.

Keep in mind that all materials are thermal insulators and have some degree of resistance to the passage of heat. However, some material has a higher resistance and thus thermal insulation. For example, fibrous or porous materials have traditionally been used, such as mineral wool, extruded polystyrene, expanded polystyrene, and polyurethane foam, among others.

Remember that having good thermal insulation implies a significant saving of money via reduced heating/cooling/energy costs in the short, medium, and long term.

Energy-self sufficiency

A big problem related to the energy consumption in residential houses is that they are typically powered by non-renewable fossil fuel energy sources. Many of these sources are in the process of running out.

Consequently, the price of these energy sources is increasing and will continue to do so. The solution is to build self-sufficient houses that depend less on external, non-renewable energy sources.

Alternatively, if this is not possible for you yet, try to invest in energy-efficient elements. For example, when choosing the appliances for your home you can choose energy-efficient ones.

On average, home appliances like clothes washers, dryers, dishwashers, refrigerators, freezers, air purifiers, air conditioners, and humidifiers will account for 20% of your household power bill.

This is why you need to know how to choose energy-efficient appliances, especially for air conditioners, as they are the ones that may consume the most amount electricity. However, this does depend on your geographic area and weather conditions.

Natural and controlled ventilation

Natural ventilation is a passive cooling strategy that is highly recommended, especially for climates with moderately controlled temperatures. Meanwhile, if you live in a place with extremely hot or extremely cold temperature, you will need to use heaters and/or air conditioners to ensure you don’t suffer or perish due to extreme temperatures.

Natural ventilation is effectively the strategic location of openings, such as doors or windows, that allows the circulation of the air with the interior spaces of a building.

To achieve maximum control and avoid heat losses, it is important to have airtight windows of very good quality. It can be recommended to have double or even triple glass if the subsequent impact on house energy efficiency is significant.

Remember that while very good quality windows represent a considerable investment, it is an expense usually worth paying because the long-term benefits are typically greater. Just think about this; about 18% of energy is lost through doors, windows, and thermal bridges, a product of poor quality and inefficiency of these elements.

Ecological Lighting

You can use LED lighting all over your house to save energy consumption. LED lighting has a lot of versatility and lets you create all kind of environments. Also, LED bulbs are not as expensive as they were before. Nowadays you can find LED bulbs near the price of incandescent bulbs.

Also keep in mind that with the installation of LED bulbs in the home, significant savings are achieved in the electricity bill, since they consume much less energy than traditional lighting systems. Even less than so-called energy-saving light bulbs, which use the same principles as fluorescent tubes.

Bioclimatic Design

Bioclimatic design

A bioclimatic design is focused on achieving thermal and acoustic efficiency in a building. This means that you will be able to live in a comfortable environment, but with minimal energy consumption. One of the key factors to consider in building an energy-efficient home with a bioclimatic design is climate.

This strategy seeks, through the use of materials in walls, ceilings and floors, to passively regulate the heat that is transmitted from the outside to the inside of the house. Keep in mind that the interior climate also depends on the air that enters and leaves through windows and on the sunlight that falls directly on walls, rooves, and windows.

Remember, if you are thinking about building a house, make it energy-efficient and enjoy all the benefits that come along with it. For energy-efficient air conditioning and lighting, please don’t hesitate to contact us to assist.

When high temperatures are practically unbearable the air conditioner is our saviour and we all know that feeling of satisfaction when we arrive home or to our well-climatized office.

We may all know how air conditioning is beneficial for us. However, not many of us know the multiple benefits it has for our health and our family’s health, and that should be highlighted.

Air conditioning provides various health benefits, especially in areas where the heat in summer is so intense it becomes unbearable. High temperatures can lead to multiple problems for our well-being such as heat stroke, low blood pressure, or dizziness. All these discomforts prevent us from enjoying moments in which we need to rest and relax as the heat can become very stressful, altering our routine.

We should keep in mind that during the summer we continue to work and we need time to gather energy to ensure full physical and mental faculties. Rest is essential, but high temperatures exhaust anyone as well as contribute to uncontrolled diseases and allergies.

For this reason, in the following article, we are going to talk about how having air conditioning at home can help you greatly when it comes to health.

It helps with allergies

An air conditioning system installed in your home provides great benefits to alleviate your allergies. Air conditioning creates a healthy environment that helps to combat allergies from accumulated dust and mites.

There are people who in the summer begin to develop strong allergies that reduce their quality of life, and this occurs both outside the home and at home. Air conditioning clears the environment of these elements that cause sneezing, itchy nose, and red eyes, among other annoying symptoms.

It reduces stress and fatigue

High temperatures can cause a lack of energy and fatigue. In many cases this is a consequence of dehydration caused by sweating, low blood pressure, and the body’s lack of adaptation to these temperatures.

Also, how air conditioning is beneficial for us. The correct use of air conditioning eliminates these effects by setting the room temperature at the optimum levels to comfortably carry out your daily routine.

Also, when it comes to extreme temperatures, you can acquire a split or ducted reverse cycle air conditioner to heat up or cool down your home during winter and summer. In this way you do not need two appliances to control the temperature at home.

Helps people with respiratory problems

These devices improve the health of people with respiratory problems, as well as help manage allergic reaction to pollen or dust. To reduce the risk of respiratory diseases such as rhinitis, sinusitis, or pharyngitis, try to control humid spaces with the ventilation function which also hinders the transmission of germs.

Keep in mind that while many air conditioning systems control humidity and also clean the air, not all air conditioners have these features. Therefore, make sure you buy an appropriate one, especially if there are already people at home suffering from respiratory problems.

Helps with the consequences of temperature changes

When there is a large temperature difference between indoor and outdoor spaces, there is a risk of dizziness, excessive sweating, or even infections. This is as a result of the sudden cooling caused by sweat evaporation when you enter a room with very low temperatures.

To avoid these problems, the idea is to condition the rooms with temperatures between 24 and 27 degrees. Also, make sure that the temperature changes are not frequent or sudden. For example, if you come home after a very hot day, it is best to gradually lower the air conditioning temperature.

It is beneficial for vulnerable people

Air conditioning is beneficial for people with a disability or reduced mobility who are affected more intensely by heat or cold. It also helps children who are very sensitive to strong changes in temperature by improving their quality of life.

Also, new-borns living in an overly warm place can experience psychological stress because their bodies are trying to regulate their internal temperature.

For this reason, an air conditioner can be the best ally for your children. It improves indoor air quality and keeps the temperature regulated.

Helps you with contamination

People who live in an urban environment tend to have more respiratory problems due to the contamination of the city. The city is full of pollution, chemicals and toxins that alter respiratory processes.

People who live immersed in nature tend to have fewer difficulties in this regard since the natural environment around them favours the breathing of fresh and clean air.

If the environment in which you live is not entirely healthy, you must consider air conditioning to favour your health. Keep in mind that if you live in the city, the air you breath may contain cigarette smoke, food fragrances, insecticides, polluting gases from vehicles, among other damaging contaminants.

Even if these contaminants are not toxic, they still prevent the environment from being clean and healthy. There is no question that this impacts your health in a negative way.

Air conditioning plays a very important role in this problem since you can solve these disadvantages by using it in a moderate way when considered necessary. In this way, you will be solving two stressful situations through a single situation: contamination and excessive heat.

What you should keep in mind

Air conditioning is amazing at helping to prevent diseases. However, if you do not give it proper maintenance it can become a great risk.

Performing regular maintenance of air conditioning systems is essential to reduce the risk of respiratory diseases.

The cleaning and quality controls of the equipment not only help to extend the useful life of the equipment and make it more efficient but also prevent the emergence of bacteria. Bacteria is not only bad for your health but can also cause disease.

Keep in mind that if you do not clean and properly maintain your air conditioning filters or the ducts through which the air travels, all the people who are under the same roof are exposed to bacteria and moisture that accumulates in them.

Remember that if you need help choosing proper air conditioning for your home, do not hesitate to contact us!

Your air conditioner becomes vital when the summer months arrive. For this reason, you should check that it is working properly all year round. Remember that many things can damage your air conditioner whether you are using it or not. You should be able to recognize if it is broken in order to fix it before the heavy, humid summer heat hits you.

For example, do you know what could be the main failures of your air conditioner system? How to check it? If you can fix it by yourself or do you call an expert?

For this reason, in this article, we aim to show you what are the common failures of your air conditioner, what are some things that may damage it, and how to know if it is better to repair it or replace it.

Lack of maintenance

One of the main reasons for an air conditioner to stop working is lack of maintenance. Remember that to extend the lifespan of your air conditioner you need to give proper maintenance and cleaning regularly. If not, your machine may present some failures you do not even know about. If you keep turning on the AC like this may cause greater damage.

Also, keep in mind that for minor task you can get tips to perform maintenance on your air conditioner yourself (DIY). However, when it is time to properly service your air conditioner our recommendation is to call an expert.

Temperature is not consistent

If the indoor temperature is too low or too high compared to normal, even when you set the exact the temperature that you want, then your air conditioner, specifically your thermostat, may be broken. This is a problem you should solve as soon as possible if you want to avoid get an expensive energy bill each quarter.

The best way to do it is to call an expert to repair the thermostat. You will not only experience energy savings but also the expert can show you how you can take better care of your thermostat.

Dirty filters

Dirty filters affect your air conditioner as they may cause poor air quality and inadequate cooling. If the air conditioner in this condition runs for too long, it can suffer several damaging outcomes.

What you can do in this case is cleaning or changing the filters, depending on how your air conditioner works. Remember that some air conditioner filters must be changed every one to three months, while other filters just need proper cleaning. Neither of these tasks are difficult, you just need some basic guidance.

Dirty drainage

Drainage can be a major problem if it is not fixed right away. AC drains can get dirty and clogged like the air conditioner filters. This can cause water to leak out of the air conditioning system due to the clogged and/or dirty drain pan. This will not only damage your air conditioner system, but also anything around or underneath the unit. This includes walls, floors, electrical items, and any other item near the aircon.

In this case, you cannot repair it by yourself. You will need an expert technician to come to repair your air conditioner if this is your case.

Dirty condenser coils

As well as with the air filters, if the condenser coil gets dirty it can damage the whole air conditioner system. At this point, you may have realized that having an air conditioner part being dirty has consequences. Please do not neglect the responsibilities that come with having an air conditioner.

What you should do in this case is call an expert to clean or even replace your condenser coil if it is necessary. Remember that if you do not take action immediately this will lead to more wear and tear and imminent damage to the AC unit.

Refrigerant leaks

The main indicator to know that your air conditioner is low on refrigerant due to a gas leak is that your air conditioner will not be producing as much cold air as it used to. You will feel the room hotter than usual even when you program the thermostat at the same temperature as usual.

Remember that the refrigerant is used to transfer heat out of a room. So, if there is no refrigerant then the heat will not be expelled as it is supposed to and will stay in the room instead. Keep in mind that refrigerant leaks are easy to detect. If you do suspect a gas leak, you should call an expert immediately to solve the problem.

What should I do if the air conditioner is already broken?

If at the end of the day your air conditioner gets broken there is some advice we have for you.

Call us!

The first thing you should do is to call an expert technician to help you fix the problem. Otherwise, you will only be extending the time without air conditioning. We can help you find out what was the source of the damage and fix it right away or present suitable options.

Get out

While you are waiting for the experts to come we recommend you go out or learn how to keep cool without air conditioning. Remember that if you stay at home the heat can become extremely high and can become harmful for you.

Do not try to fix it by yourself

Depending on what happened to your air conditioner it could be dangerous for you to touch. Also, you can easily damage the aircon system even more. The best thing you can do is be patient and wait for the expert that can help you fix the problem.

Do not use heat-generating devices

At least until your air conditioner gets fixed avoid using heat-generating appliances because this will generate excessive heat load indoors. It will not directly affect the air conditioner at all, but it will affect your comfort levels as you will not be having any source of cool air.

For example, avoid using the washing dryer and when it comes to cooking it is better to use the outdoor BBQ instead of the stove or oven. Just until the air conditioner repair is completed.

Remember that if you have any questions we are here to help you. Please don’t hesitate to ask us anything.

When an air conditioner does not cool it can be due to multiple reasons, not simply due to a lack of gas. Most people think of this as the first option, but it is not the only option and certainly the majority of the time it is not the most accurate diagnosis.

Consider that if the air conditioning installation was done properly, the gas should not be lost unless a leak has occurred. For this reason, most of the time your air conditioner not cooling the environment or not cooling enough is due to other factors.

In the following article, we will state several reasons why your air conditioner may not be cooling. Keep in mind that once you identify the reason that fits your case you should take proper action immediately.

Control or thermostat incorrectly configured

Although it may seem silly, there are many people that get confused when turning on their air conditioning system because they do not know how to set the operating mode correctly.

A high percentage of the time, most air conditioning problems are simply due to an incorrect remote control setting. If for any reason you cannot configure your remote or wall controller, it is best to reset it to the factory settings. Once done, you can continue with the tips that we show you below.

First, for cold air conditioning, you must ensure that you have cold mode selected. This is typically a snowflake symbol. It is easy to get confused with the dehumidifying mode, which is typically a drop of water symbol.

Once configured, you need to be patient. This is because in most cases an air conditioner unit may take up to 10 minutes to work once you turn it on with the controller.

Haven’t used the equipment in a while

When you turn on your air conditioner for the first time after not using it for a long period of time, it takes a while for the compressor to start working so that the environment starts to get cold. It usually takes between 3 to 10 minutes, but sometimes even longer depending on the brand and age of the system.

What happens to many people is that when they realize that the aircon is not cooling, they start to touch different buttons thinking that there is something incorrectly configured. The only thing you get with this is the delay remains paused until you stop touching the buttons.

For this reason, you have to put on cool mode, adjust the temperature and ventilation or fan speed, and wait for 3 to 6 minutes. Do not despair and be patient.

If after waiting several minutes without touching anything, with the remote set correctly, it still doesn’t work, then it is better to contact a technician so he/she can see what is happening.

Problem with the start or run capacitor

When one of the start or run capacitors does not work, either for the fan or the compressor, you will see that the indoor unit is working correctly but is not cooling at all.

When a fan capacitor is deficient, it does not pass on power to the fan motor and the outdoor fan will not work. In this case, it is most likely that a fan-run capacitor is damaged.

On the other hand, when the compressor capacitor is not working, you will see the outdoor fan working correctly but the compressor will be stopped. In this case, it is most likely that the compressor start capacitor is faulty.

In these cases, you need to call an expert to solve the problem. Capacitors can hold their charge long after the air conditioner unit is turned off.  This poses a serious risk of electrical harm if you try to remove or replace any parts on your own.

Dirty air filters

When air filters are dirty, there is a drop in pressure in the indoor unit because the air does not circulate as it should. As a result, you may notice that the equipment cools, and even freezes at the indoor coil, but does not cool down the room.

This will result in higher energy consumption. Even high-powered equipment may stop due to the pressure switch tripping. The AC pressure switch is a safety feature for the aircon for when the pressure is too low or too high.

To clean the air conditioner filters you can simply do it with your hands and a little soap. You can also use a soft cell brush and hot water to make them cleaner and more disinfected. Also, try to perform regular maintenance on your aircon.

Gas leak

Lack of gas may be due to a leak in the refrigeration circuit. This could be either because of an error in the installation or because a small hole has occurred in a pipe due to vibrations, corrosion, or physical damage.

A leak may also have developed within an AC unit itself. Indoor and outdoor coils are the most common internal leak locations, and may be covered by manufacturers’ warranty if the air conditioner is less than 5 years old.

To solve this problem, you will have to call a specialized technician to detect the gas leak.  They can guide you as to whether it is an installation fault, AC unit fault, or simply due to wear and tear.

Outdoor or indoor fan not working

This can be due to various factors. For example, the condenser may be in poor condition, preventing the fan from moving or allowing movement with difficulty. Alternatively, one of the fan blades may have broken, which affects proper functioning of the aircon equipment.

In this case, it is also extremely important to call an HVAC technician so he can check what is exactly happening with the fan. DIY in this area can lead to further damage to the air conditioner or yourself.

Extremely high temperature outside

Air conditioners need to transfer heat from the circulating refrigerant to work properly. When the outside temperature is too high, adequate cooling may struggle to occur.

It may feel like your air conditioner unit is not cooling the indoor space if the ambient temperature is extreme. In this case, the drop in temperature from outdoor to indoor is not sufficient to create a comfortable indoor climate.

A temperature difference of around 10 degrees is considered normal. So, if it’s 30 degrees outside, you could achieve air being blown out of the indoor AC unit at 20 degrees. This is with a fully functioning air conditioning system.

However, if its 40 degrees outside, the aircon would struggle to pump out air below 30 degrees indoors. The system would be pushed to its limits, it would take longer to cool the indoor area, and the degree of cooling experienced may be limited as a result.

Further issues arise when the outdoor AC unit is placed in some type of metal drawer, wooden box, storage area, or any other scenario where ventilation is not good. This reduces airflow, heat rejection, and the subsequent cooling capability of the air conditioner.

To solve this problem, you have to lower your expectations of an air conditioning system on extremely hot days and/or move the outdoor unit to a better place or at least clear obstructions around it.

Useful tips for when we see that our air conditioning does not cool well

The first thing you should do is review all the previous points and identify what your problem could be. After that, if you need help you can contact us to check your aircon system. Otherwise, if it can be solved by yourself, keep in mind that you can give us a call or leave us a comment so we can assess and potentially assist you in the process.

Also, please be aware that you should never manipulate any unit without having HVAC technical knowledge as you could sustain damage in an accident. Apart from further damaging the air conditioning system, you could harm yourself or those around you. Surely it’s worth playing it safe. If needed, we are here to help.

Imagine being perfectly fine at home then suddenly feeling that the temperature inside is no longer comfortable anymore. The worst thing that could happen is having your air conditioner break down at the peak of summer. This could happen to you and you need to be prepared. 

The first thing that you need to do is act quickly. If your air conditioner is not working anymore, do not panic, call an HVAC specialist. It may be the case that you want to check it out yourself first, however, we recommend avoiding wasting any time as your home can get hot in a matter of minutes.

If you call an air conditioner specialist as soon as you realize your air conditioner is broken, then chances are they can get to your home the same day. If you phone late in the day, then worst case looking at the next morning.

Now you know what you should do, we would also like to be honest with you about what you should not do. Remember that if you do something wrong while the specialist is on his/her way, you may damage your air conditioner even more and make it more difficult (and expensive) to fix it. 

Keep using the air conditioner

If your air conditioner is broken, there are two ways in which you typically detect it. The first would be due to a total shut down of the system. In this case, you won’t be able to turn it on again. So all that is left to do is call an air conditioning technician.

However, there are some situations where the air conditioner will still work. Even when it won’t work properly, you will be able to use it. But this is not recommended at all! If you detect a failure in the operation of the system, turn it off immediately. 

Keep in mind that if you continue to use the air conditioner you can cause even more damage and make it harder to fix it. This could represent more money for you. So please, at the moment you realize your air conditioner is broken, turn it off, call the specialist, and wait patiently for someone to come and assess/fix the problem.

Leave your air conditioner like that

When your air conditioner is not working properly you can notice it right away. If your air conditioner is not cooling like it used to, or you feel heat air instead of cooling air, these are clear signals that something is wrong with your air conditioner and you can’t just ignore it.

You would be surprised by how many people just think, “oh well I do not have time for this” and just leave their air conditioners like that. You cannot ignore the problem and you cannot ignore these obvious signs of malfunction. 

Remember that at some point the problem will get bigger. This will only represent a bigger headache for you, more money to spend on the repair, or having to replace the whole aircon system. 

Try to fix the air conditioner by yourself

There are some things that you could do by yourself when it comes to performing maintenance on your air conditioner.  For example, you can and should clean the filters regularly or you can restart the aircon by yourself if something is not working properly. However, actually fixing your air conditioner is not something that you should perform on your own. 

Many people that think, “how difficult this could be?”. Please trust that is not as simple as you may think it is. For this reason, HVAC specialists spend years studying and training to do their job.

Staying at home

As we said before, on summer days your home can get hot within minutes if your air conditioning is not working properly. For this reason, on hot days, we recommend you look at leaving your house while you wait for the technician to arrive. 

Keep in mind that at a certain point, this could even become dangerous for your health as your body is not able to cool itself. You can suffer from heat exhaustion, heat cramps, heat rash, and even a heat stroke. It’s not worth risking it. 

You can spend your time at a shopping centre or cinema, visit family and friends, go for a drive, or even just spend the day outside in the backyard. Any of these can help improve the situation and reduce the risk of heat illness. 

Use heat-generating appliances

If your air conditioner will take some time to get fixed, try to limit the use of heat-generating appliances indoors in the meantime. Keep in mind that not having air conditioning on hot days is already hard, so imagine adding more heat to the environment. The indoor environment can become unbearable.

For this reason, try to switch your stove or oven to an outdoor grill instead. Try not to use the washing machine, drier, or dishwasher during the day or at all. You can try to do these things in an old fashioned way, often by hand. Finally, turn off the lights that you are not using and keep your computer and TV unplugged when you are not using them.

Not having a plan b

Having a broken air conditioner is something that may happen to all of us but, as mentioned, you need to be prepared. We recommend that you have a portable air conditioner so you can use it in a situation like this. A portable air conditioner is not the same as having your air conditioner fixed, however, this can avoid you suffering from excessive heat indoors.

Also, you need to be informed on how to keep cool without an air conditioner. This is especially handy if the repair is going to take a long time. 

For example, you should know that the worst thing you can do may be to open the windows at certain times of the day because you will only be letting in more heat into your home. Also, you should keep your windows and curtains closed when your air conditioner is not working. 

Female asking for a service to a HVAC technician

We hope you found this guide useful and now that you know what you should not do if your AC is broken. Keep in mind what you have to do, and call an HVAC specialist to get your AC repaired as soon as possible. 

Imagine arriving home from a long and exhausting day, turning on your air conditioner and finding it is smelling really bad. Do not panic – there is a solution!

The most common reason that your air conditioner has an unpleasant smell is dirt and mould in the indoor unit.  Another main reason for the odour is not produced by the machine itself but by the drain, and the aircon is sucking it up and spreading the smell.

In the following article, we will tell you the main reasons for the bad odour and how you can solve it if it is possible, before considering calling an expert to service your aircon.

Refrigerant leak

If your air conditioner smells like a car’s exhaust, then this often indicates a refrigerant leak. Remember that your air conditioner does not work with a combustion engine, although this particular odour may be a result of the mix of fluids and heat.

In this case, it is important to stop using the air conditioner unit and call an expert as soon as possible as it can be dangerous. A refrigerant leak means that your air conditioner will not perform properly, which can result in further damage to key (and expensive) components like the AC compressor.

Furthermore, this scenario means chemical compounds are being released into the air. This refrigerant gas in the air that can affect yourself, your family, and the environment.

Also, while you wait for the expert to arrive, open the windows of your house and keep your home ventilated. This will help reduce the damaging effect of the chemicals.

Stuck animals

If your air conditioner is smelling like a rotten egg, this may mean that a rodent or any other animal has become stuck in the air conditioning system somewhere. This unfortunate event is not immediately dangerous to the health of your family.  However, it is important to solve the issue as soon as possible to avoid discomfort and more serious concern.

The best you can do if this is your case is find the exact location and extract the animal, as long as it is safe to do so. Clean the area and make sure you leave it dry so the odour doesn’t spread anymore or allow mould to form.

For future occasions, it is better to prevent this from happening by pest-proofing your aircon and home in general. For advise on how to prevent unwanted animal intruders, it may be best to contact an expert to discuss options.

Dirty air filters

If your air conditioner smells musky, mouldy, or like vinegar then this could be due to dirty air filters. On the other hand, if it smells like humidity/moisture, then the main cause may be water accumulating in the drain pan or ducts causing fungus to grow.

If you are suffering from water leaking you will also see it as water dripping down your wall, through the unit. This causes all sorts of property and electrical damage, and should not be left.

In any of these cases apply to you, it is better for you to call an expert so they can clean everything from the source outwards and manage the leakage as needed. Remember that regular air conditioner maintenance is important to avoid this kind of problem.

Burned air conditioner components

There are many electrical components in your home air conditioner.  If your aircon is expelling a burnt odour, this is likely because any of these components may be burning on the inside. For example, this could be due to a dead short and/or motor burn out.

If this is your case, then turn off your aircon immediately and call an expert to review the air con units. Do not try to fix it by yourself because it can be very dangerous.

Alternatively, if you haven’t used your air conditioner in a long time, the burning smell from the aircon unit could be due to dust burning a little bit on the inside. This is not necessarily dangerous. However, if the odour persistent then best to turn it off and call an expert.

Air conditioning odor at home

Cigarettes smoke smell

If your air conditioner smells like cigarettes smoke then this might be due to smoking in your house from you or your family. What you can do, without the help of an expert, is thoroughly wash the air filters more regularly and replace when needed.

Also, to avoid this strong odour that may cause allergies and headaches, obviously try to smoke outside. If looking to quit, don’t hesitate to reach out for help quitting once and for all.

Aircon smell immediate solution

If you have read the article so far and what we recommend for your situation is safe for you to go ahead with, then you can move onto the following:

Check the filters

A common reason for the appearance of unpleasant odours is the presence of dirt accumulated in the filters. This is because they progressively grow odour-causing bacteria or mould as a result.

Regular cleaning of the filters, in addition to preventing unpleasant odour, will help reduce the need for aircon repairs and reduce energy consumption. Such a simple step to save so much discomfort, breakdowns, and money!

In general, the filters should be checked and cleaned once every two weeks in winter and once a week in summer. Simply remove them, wash them with hot water and mild soap, and replace them once dry.

Woman checking the air conditioner

Clean the outdoor condenser

Generally, the outdoor unit of the equipment does not usually have a filter, so all the dirt from the street is deposited in the heat exchange coil in the AC condenser. Unfortunately, this dirt reduces the efficiency and thermal power, and cause more serious issues.

The unit and coil can be lightly brushed with a soft brush, or air used to blow off any matter built up.  However, more intensive cleaning or hard brushing is best left for the professionals. If not done properly, this can cause refrigerant leaks and/or electrical failure.

Check/clean condensate tray

The water condensate tray is responsible for a large proportion of unpleasant odours in air conditioning equipment. The smell can come from the water or matter growing in it.

We recommend that you clean the tray, at least once a year, with a disinfectant solution and check that the evacuation system is not clogged. This can be done carefully or left for a professional to do on annual-level service.

The drain

The drain of the indoor unit, which channels away water from condensation, is also the cause of many unpleasant odours in the aircon environment. If it is connected to the general drain of a building, these odours may come from there.

To solve this, it may be enough to place a siphon in the tube before connecting it to the general drain of the house. Otherwise, more serious intervention may be required.

Remember that if your air conditioning situation is presenting a risk to you, please call an expert to solve the problem. Trying to solve it by yourself when not appropriate is a common aircon mistake you should avoid as it can carry consequences from mild to major.

It is a priority for homeowners to offer a comfortable and well-equipped place with all the essential appliances for tenants.  However, this is not always the case, especially when it comes to air conditioning.  Let’s face it, for leased apartments, air conditioning is not commonly included.

This could represent a problem for the tenant because this may mean great discomfort in the rented place.  However, unfortunately, installing an air conditioning is not a landlord obligation.  In the best-case scenario, you may ask your landlord to install an air conditioner system and negotiate coverage of the investment.

How to negotiate this?

Shared responsibility

From the beginning, you can talk about this matter and negotiate in a way that is fair for both parties.  Normally the landlord wouldn’t want to spend more than he/she has to, so it is a good idea to propose shared responsibilities.

You as a tenant would pay for the maintenance and the repairs while the landlord would be the one to install it or replace it if/when a new one is needed.  It is a good idea for the landlord and tenant to contract a qualified air conditioning service company for the installation/replacement, ongoing maintenance, and repairs.

This agreement may include filters cleaning, duct maintenance, and the replacement itself if/when required.  However, the tenant should be responsible for replacing the system if it gets damaged by his/her negligence.

You, as the tenant, will pay it all

You, as the tenant, should be aware that in the contract you may have all the responsibility for HVAC maintenance, repair, and replacement.  This may cause tension between the tenant and the landlord because it seems like something that is not fair for one party.

Carefully read any contract and try to negotiate or go for the shared responsibility.  Keep in mind that this kind of contract will not be cheap and it may be preferable to include the costs in the monthly rent.

Limited responsibility

If the installation of a new air conditioner system is needed then the landlord may divide the total price of the new aircon by its useful life, that is normally 12 to 15 years.  In this way, he/she will add this price to your annual contract, so you will pay based on how many years you stay in this property.

This is also a fair type of contract because, either way, the landlord should include a price of having an HVAC system in place.

What is the best air conditioner in this case?

A common air conditioning option is a window air conditioner because it doesn’t require too much installation work.  Also, if it is the case that you as a tenant will be the one investing in this aircon then it is great for you because of the portability and low upfront cost of box unit installation.

Also, landlords prefer this option because it can minimize the possibility of damaging the interior of the property.

What is window air conditioning?

This kind of equipment has all the elements within the same device.  When it is installed, the condenser is on the outside of the room while the evaporator is on the inside.

The installation of a window air conditioner can be carried out on walls and windows and also it has a powerful refrigeration capacity.

Window air conditioner in leased home

What are the features of window air conditioning?

Easy installation

One of the most outstanding characteristics of the window air conditioner is that its installation is very easy to carry out.  This kind of unit can be up and running in a few hours from its installation.

This type of air conditioner can be placed in the opening of a window and its installation is the simplest option out of all the different types of air conditioning systems since it does not require any type of complicated work.  You can even install it yourself.

Another option is to embed it in a wall, either under a window or in a wall that does not have this kind of opening.  For these options, a cavity has to be made in the wall to install the unit.  In this case, the tenant should always have the approval of the landlord.

In this way, half of the equipment will remain inside the room and the other half will stand out from the facade of the building.

All in one solution

The window box air conditioner is an all-in-one system, this means that it works with a single unit.  It incorporates all the necessary elements to work in the one box!

Since it is not necessary to connect two units, like a split model, it is also easier to manage.  However, it’s worth noting that repairs can be limited by its simplistic nature.

On the other hand, as there are different types of wall air conditioning units with increasingly compact and modern alternatives.  A wall unit it is an excellent option when the space you live in is small.

Lower cost

Another great feature of the window air conditioner is the low-cost equipment, compared to other alternatives on the market.  Generally, this kind of unit represents a much lower investment than other types of models, which is great for the tenant and the landlord regardless of who is going to invest.

Practical units

Window air conditioners are really practical because even when you already installed it in a window you can easily move it to another room.  In the case that you as the tenant invested fully in this air conditioner unit, when you move to another place then you can take it with you.

Also, they can be adapted to just about standard room around the house and their performance can be wonderful.  Since there are more and more models that incorporate environmentally friendly, efficient refrigerants, they are transforming into very efficient units.

What is the best brand of the window air conditioner?

Remember that each brand has its unique advantages and the best brand for you also depends on your needs.

For this reason, we encourage you to contact us as we can give you better advise once we know your exact needs.

There are many common mistakes made with air conditioning.  From pre-purchase decision making and installation, through to usage, maintenance, and even assisting the air conditioner, there are many pitfalls to be aware of and avoid where possible.

The mistakes vary from minor to major, and can result in a range of different air conditioning outcomes.  The stakes are high as they affect air conditioner performance, efficiency, and safety.  They also affect your hip-pocket as heating and cooling can account for half of all home energy usage.

Furthermore, poorly installed, used, and/or maintained air conditioners can result in the growth of microorganisms and other nasties that can be harmful to your health if inhaled.

In this article we’ll outline some simple tips, checks, and adjustments you should be aware of to help the health of you, your family, the air conditioner, and hip pocket.

AC Unit Selection & Purchase

1. Not considering air conditioner installation

Before even purchasing and installing an air conditioner, you may make the common mistake of not considering the value of aircon beyond the basic financial sense.  It is truly worth taking into account the many health, wellness, lifestyle, and even economic benefits air conditioning can provide when making your initial decision.

If you already have air conditioning then it may be reaching end of life, but you resist the need to purchase a new air conditioner.  Don’t make the mistake of patching or pushing your old aircon past its reasonable lifespan.  While the initial cost of AC replacement is relatively high, it may be the most financially viable option as repairs start becoming more frequent and costly.

The new system will also be more efficient compared to older models as technology evolves every year.  This will help decrease your power bill and save you money over time.  If your home air conditioner is over 10-12 years old and requires substantial repairs or is energy-hungry, it is worth considering investing in aircon replacement.

2. Installing the wrong AC unit type

When selecting an air conditioner type for your home or business, you must consider the bigger picture.  It can pay to look long term from the very beginning.

For example, if you want to heat or cool a single room, sure, you can arrange for an aircon unit to be installed that suits that room.  Maybe a wall split system, window/box unit, or a ceiling cassette system.  Then the following year, you decide to cool another room, and repeat the process.

If this continues over a number of years, you may surpass the cost of something like a ducted system.  A ducted system may in fact be a more suitable residential or commercial air conditioning system, but now it’s too late as you’ve forked out a fortune in individual units throughout the home or office.

Alternatively, you may decide to renovate.  Now the individual DX systems are no longer suitable for the areas they serve.  This is why you really must consider your heating and cooling requirements now and into the future before spending a cent on any AC unit.

Different type of air conditioners

3. Replacing like for like without question

If you are replacing an existing aircon system, you may the mistake of automatically replacing it with the same style of system.  Just because you have floor-mounted split system or box/room air conditioner, doesn’t mean you need to replace it with the same unit type.

A wall-mounted split air conditioner may actually be a more suitable option compared to other styles you already have in your home.  It is worth speaking to a reputable air conditioner installer who could quote like for like and other suitable options for you.

Similarly, many people make the mistake of replacing their existing system with the same capacity (kW rating) system without a moments thought.  It pays to ask yourself 3 main questions when replacing your air conditioning system:

  1. Did my system adequately heat or cool the room when it was working as designed?  E.g. it took too long to warm up, or never really cooled down the space that well.
  2. Has the function of the room changed since the aircon was installed?  E.g. was a bedroom, but is now a study with computers, screens, printers, scanners, modem, and other heat-generating equipment.
  3. Will the function of the room change over time?  E.g. dining room may become a media room.

4. Installing the incorrect size air conditioning system.

Like Goldilocks and the Three Bears, there will be an aircon size that is just right for a room or whole building.  As mentioned previously, if you are replacing an existing system, you may the mistake of automatically replacing it with the same sized system without question.  With capacity, further to the 3 key questions, you can’t always assume that the correctly sized air conditioner was installed originally.

If a system is undersized, it will continue to run non-stop when on.  This will cause the system to be overworked, causing it to wear out faster and breakdown more often.  An undersized air considering will struggle or even fail to bring the indoor temperature up/down to the desired level, causing great discomfort and frustration.

An oversized air conditioner will continue to cycle on and off, causing premature damage to the compressor and other internal components.  This will also cause the system to breakdown quicker and shorten the expected lifespan.  It will also blast hot/cold air, then stop, then blast, and so on, creating an inconsistent and uncomfortable indoor environment.

If the new or existing AC unit didn’t seem sufficient, or you have any doubts, ask an expert air conditioning contractor what size air conditioner you need.  They can offer some advice after considering all factors in determining suitable kW rating; room size, ceiling height, building orientation, building materials, insulation, window size/number, heat load, and room usage, just to name a few.

5. Selecting the wrong aircon brand

There are a lot of different air conditioning brands on the market, creating overwhelming choice.  The range is also expanding annually as existing manufacturers diversify and new players enter the market.  Many people make the mistake of selecting a brand of air conditioner based on limited factors or even just one reason.  However, there are many factors to consider when deciding what air conditioner to buy.

AC brand may be selected on price alone – the cheapest aircon brand available may be selected.  However, this may cost you more in the long run as some brands have shorter lifespans, some cheap units have horrendously expensive replacement parts, and some don’t even have spare parts readily available.

AC brand may be selected on name alone – the most well-known brand may be selected without a second thought.  However, popularity doesn’t always mean it’s the best aircon brand.  Some popular home air conditioner brands, with frequent promos like cash back, can have a range of painful post-install issues such as long delays in spare parts and even lack of parts before the system even gets close to the end of its reasonable lifespan.

This is a tricky one, as there is not one AC brand that fits all; they all have their own merits and drawbacks.  The best thing to do is chat to a reputable air conditioning company about who they recommend and why.  Alternatively, you can do your own research online looking at balanced and unbiased sources.

6. Not considering refrigerant type

There are 2 reasons why choosing the right gas or freon is important when planning an air conditioning installation.

  1. Certain refrigerant can be poisonous with long or even short-term exposure. E.g. R410A.
  2. Certain refrigerants are being phased out and now heavily taxed and restricted by the government as a result.  E.g. R22.

It’s also important to make sure there is nothing in a new air conditioning system except the refrigerant designed for the AC units.  The wrong refrigerant can cause premature failure of internal components, costly repairs, and even complete system failure.

Another major issue with incorrect refrigerant in a system is reduced power efficiency.  Non-condensables in an AC system do not flow normally through the pipework and build up in the outdoor condenser coil.  This causes higher pressures, higher compressor electrical usage, and lower heat transfer.  The result?  Short-term: reduced efficiency.  Long term: premature system failure.

7. Not considering style or design

Air conditioners have become more attractive in recent years.  This is primarily in response to consumer demand and changing style trends.

With smaller head units, gentle curves, and cleaner lines, today’s aircon units do a better job of blending in with modern and landscape design.  The range of colours has also expanded, with blacks, blues, reds, metallics, and wooden finishes.

Designed living room with air conditioner

In some homes and businesses you can hardly even notice that air conditioning is there, with quiet bulkhead units placed flush into the ceiling so that only the suction and discharge grilles are visible indoors.  This is a great option for those wanting minimal impact to internal aesthetics and acoustics of a room.

8. Failing to consider the AC model

Most AC brands have a range of models available.  Some have valuable features, while some added extras that may not be necessary.  Many people make the mistake of going with whatever model is on sale or presented to them at the time without being aware of other, potentially more suitable, models from a given manufacturer.

Many people assess the full product range for a given brand before purchasing, whether it be as major as a car or as minor as sliced bread.  So why not for something as significant as an air conditioner?

For a Daikin aircon, its worth having a read about the differences between Daikin wall split systems currently available.  A little research and reading can help you work out which model or series is the best for you, your budget, and specific needs.

9. Buying units from the wrong supplier

When it comes to purchasing an air conditioner, there are a variety of suppliers to choose from.  You can buy your air con unit from a general retailer, wholesaler, online, or from an air conditioning company as part of a package deal (i.e. supply and install).

Most of the time, purchasing the system through a reasonable air conditioning company will be cheaper than purchasing it through a general retailer.  Even if you do find an air conditioner cheaper elsewhere, you will likely pay more for the install only portion when not part of a package.  This means you end up paying more overall when sourcing the new aircon separately to the install.

You can save money buying through an AC company because they usually buy in bulk and/or have trade accounts with wholesalers.  This means the company receive greater discounts on air conditioner units, which should then be passed onto customers.

Air Conditioning Installation

10. Using the wrong installer

It’s true what they say, especially in the world of air conditioning; you get what you pay for.  Installation costs can vary dramatically, but buyer beware.  People can make the mistake of just looking at initial cost when choosing an installer.  This can result in greater expense, pain, and frustration.

Good aircon installers use the correct materials for every installation.  This ensures optimal running conditions for the AC system.  This also affects efficiency and reduces running costs.  Professional air conditioner installers also take the time to ensure that units are level.  This helps prevent system components from wearing unevenly and/or failing prematurely.

Good AC installers also ensure all connections are secure to prevent water or gas leaks.  Not only does this prevent avoidable repair costs, it also helps the environment.  For example, 1kg of R410A refrigerant has the same greenhouse effect as 2 tonnes of carbon dioxide.  This is equivalent to running a standard car for six months!

If you can look at the bigger picture, you may end up saving more in the long run by choosing a better air conditioning installer.  This includes more money, more life from the AC, and more peace of mind.

11. Poor wall split indoor unit location

Many mistakes can be made when it comes to indoor AC unit placement during installation.  As a general rule of thumb, the best place to install a wall split unit is:

  1. On an external wall,
  2. High up and close to the ceiling, and
  3. Near the middle of the room.

The location of aircon units can have a significant impact on the installation complexity and therefore price.  It costs far more for an up and over installation, where pipework and cables run up through the ceiling, compared to a standard back-to-back installation.

For a back-to-back installation, the indoor unit is installed on an exterior wall with the outdoor unit installed on the other side of that wall.  Less materials, less complication, and less labour means a cheaper, faster air conditioner installation.

A high wall location close to the ceiling helps to counteract the well-known phenomenon; hot air rises.  This way, cool air is pushed closer to the ground where people reside.  It’s often recommended to install a wall mounted indoor unit at least 2.4-3.0m off the ground, while ensuring still reasonably accessible for routine maintenance and cleaning.

Similarly, a central location ensures the conditioned air is spread evenly around the room.  The indoor unit should be located where the air can be distributed throughout a room with minimal to no obstacles.  This helps ensure temperature and airflow consistency, as well as supporting maximum system performance.

12. Poor ducted indoor unit location

Wall splits are not the only units that suffer from poor location selection; split ducted indoor units can be installed in the wrong location also.  Due to ignorance or laziness, the indoor unit can be installed in the most convenient location at the time, rather than the most convenience location for future access, maintenance, and repairs.

A ducted indoor unit it typically installed in the roof, behind a solid ceiling in a home or false ceiling in an office.  The indoor unit often goes up into the ceiling through the return air grille hole.  It may then be installed there, or preferably closer to the manhole for future ease of access.

The unit may also be installed hard up against or very close to the ceiling or structural beams in the ceiling because easier at the time.  However, this type of installation may prevent panels being removed in future when needed for servicing, indoor coil cleaning, and/or repairs.  As a result, ceilings may need to be cut open and/or major building works undertaken, just to attend to a poorly installed indoor ducted unit.

13. Poor outdoor unit location

The outdoor unit for any air conditioning system be installed in a variety of places, some suitable and some not so great.  There are a number of points to consider to avoid the mistake of installing the condensing unit in the wrong location.

Firstly, the air conditioner condenser is a major component affecting overall air conditioning system operation.  The less work the condenser has to do, the more efficient the whole system is.  Sunlight and heat increase the workload for an already-hardworking unit, therefore it is recommended to install it in a shady, cool location wherever possible.

Installing a condenser down on the ground in a shady ventilated location, as opposed to up on a roof top, also assists with ongoing service and maintenance.  A technician’s work on a condenser is limited if it is too hot, too high, or too exposed during the day due to modern-day workplace health and safety regulations.

14. Wrong outdoor unit attachment/support

Once an outdoor unit location is correctly established, it’s then important to ensure it is secured to a building or placed on the ground correctly.  Unfortunately, many people still get this install aspect wrong, with great consequence.

Most outdoor units are either installed down on the ground, raised up off the ground onto a wall, or placed up on a roof.  For units installed on the ground, these are sometimes incorrectly just placed on the bare earth or an old pathway/surface.  These surfaces may not be level, firm enough, or stable over time.  A better option is to install the condensing unit on a pre-made, stable poly slab.  This avoids stressing the pipework, looks a lot neater and tidier, and stops any grass or weeds growing through to the unit.

For wall-mounted outdoor units, these are still occasionally bolted directly to the building.  You’ll certainly know about it if this is the case, as condensers generate a lot of vibration and noise that can travel through a wall.  The correct method involves attachment to wall brackets with special mounts, padding, leaving a gap, or a combination of these.

For condensing units installed on the roof, these are not always secured correctly.  A reputable installer will use suitable methods of attachment, including a strap over the top when required.

15. Failing to correctly install isolation switch

As per Australian Standards AS/NZS 3000 (aka the Wiring Rules), since December 2012, all new air conditioner installations require their own lockable isolation switch be installed and a Certificate of Compliance (COC) issued.  A COC can only be issued by a licensed electrical contractor (this is an additional license to an electrician).  Incorrect isolation switch installation at your property is unsafe and a serious liability.

The isolation switch should also be directly adjacent to, but not on, the outdoor condenser unit.  For roof-top unit installations, a separate isolator stand may be required to achieve the correct isolator position.  Unfortunately, poor AC installers can still make the mistake of installing isolators on the condensing unit, which is not only illegal but can also damage internal components such as printed circuit (PC) boards or even refrigerant pipework.

Furthermore, the isolation switch should be as accessible as possible.  It is designed to protect the air conditioner, but also serves as a point of isolating power to the unit prior to undertaking certain service or repair tasks.  It is also useful for resetting an air conditioner after a surge or other event that causes the system to trip out and/or stop working.

Aircon isolator

16. Poor or unlicenced electrics

Isolation switch aside, there are a wide range of electrical mistakes made when it comes to air conditioning installations.  Incorrect power run, overloaded switchboard, exposed wires, lose connections, and incorrectly installed components can wreak havoc in so many ways.

A dangerous mistake is DIY or unlicenced electrics.  This can come with heavy fines and penalties.  A fully qualified air conditioning technician and/or electrical contractor should be the only people working on your air conditioner electrics.

If an air conditioning installation is not done correctly, the system can obviously fail to work properly.  Furthermore, it can cause faults with the air conditioner unit and/or electrical circuit in the building.  Finally, and most importantly, poor electrics can start a fire or cause physical harm to humans and animals.  It’s certainly not worth the risk!

17. Poor drainage system

An inadequate drainage system is an all-too-common mistake made during many air conditioner installations.  Standard aircon units generate a significant amount of moisture (condensate) during operation, and that moisture must be suitably drained away.  If not, damage will likely occur to the AC unit and surrounds.

The surrounds can include rooves, walls, floors, as well as property underneath such as TV, furniture, carpet, and more.  Water build-up in the roof can lead to whole ceiling collapse, which happens more commonly than you may think.  Water in the walls and other areas of your home can lead to damp, rot, mould growth, and drywall deterioration.

To avoid such issues, ensure you use a reputable aircon contractor to carry out your air conditioner installation.  Ask them about the drainage system – where will the water run to?  It’s also vital for routine AC maintenance to be carried out to pick up any issues and clear any blockages before they become disastrous.  Don’t hesitate to call for help if your air conditioning system is leaking water.

18. Lack of drip tray and/or safety tray

Further to condensate drainage from the AC unit, safe-guards should also be installed to prevent more serious damage in the event of primary drain failure.  Unfortunately, these can be mistakenly forgotten or blatantly left out.

A blockage or primary drain failure can lead to an overflow of water where it shouldn’t be.  For split and ducted AC units, a drip tray should be installed (under the indoor evaporator coil/unit) to catch any such water and prevent it falling further.  A safety tray can also be installed under a ducted unit to further protect from water falling onto the ceiling and anything below it.

To protect yourself, your property, and your belongings, it pays to ask your aircon installer about this.  What safe-guards are in place in case of a drain blockage?  How can you check these safe-guards in your system?  A few questions now could save a lot of damage, pain, and expense down the track.

19. Poor ductwork design/layout

There are a wide range of different companies offering new ducted air conditioning installation.  Unfortunately, there are many mistakes made in the design process by inexperienced and underqualified ducted aircon installers.

The process typically starts with designing the complete system, including ductwork for the ceiling.  Too many zones and/or outlets for a given AC capacity (kW rating), inadequate flex size and/or number, and too many or not enough supply air outlets are just some of the mistakes made.

The design of ducted system is best left for companies specialising in ducted air conditioning.  Otherwise you may lose the money you saved on a cheaper installation, and much more, through inefficiencies and inadequacies.

Furthermore, the system may never work properly.  What a waste!  At the end of the day, if you are going to spend thousands of dollars on a ducted install, it’s well worth paying that little bit extra for a reputable company to design and install.

20. Incorrect flex type/sealing

Another common ducted aircon mistake is using the wrong type of flex or duct, and failing to seal it properly.  Only fire retardant ducting should be used in ducted air conditioner installation.

Furthermore, the correct rating should be used; At least R1 for home air conditioners, and typically R1.5 or higher for commercial heating, ventilation and air conditioning (HVAC) systems.  Unfortunately, these requirements are not always followed by sub-parr ducted installers.

Another common ducted AC install mistake is inadequate sealing the flex on ceiling.  This mistake reduces the efficiency of the ducted system, as air escapes through the gaps and is wasted into the ceiling space.  It will also push up your power bill as energy is wasted heating or cooling your roof void.

21. Incorrect refrigeration pipe type

In a bid to undercut the market, too many installers cut corners and/or make the mistake of using the incorrect refrigeration pipework for unit installations.  Pipework used should be pre-insulated, annealed, UV-rated, copper pair coil, specifically designed for air conditioning and refrigeration installations.

Pipe insulation improves system efficiency.  It also helps prevent sweating that occurs without it, and the resulting water damage and associated issues in any area adjacent to or under the pipe run.  A little water can quickly build up to become a major issue, including ceiling collapse, dry rot, damp, mould, and sick building syndrome.

UV-rated pair coil is proven to last longer under the sun’s harsh UV rays and slower to degrade in general.  Unrated, inappropriate pipework can start to breakdown and cause issues in as little as 12 months, so it pays to ensure the correct pair coil is used for your aircon install.

Another common mistake is incorrect refrigeration pipe size selection.  There are 4-5 common pair coil sizes used for modern day home and commercial air conditioner installation, and they are more expensive per roll as the sizing increases.  Some cowboys try and get away with using a smaller pipe size to save a few dollars, to the detriment of the air con system installed that will never work to its full potential.  On the flip size, oversized pipe can also cause problems including compressor damage.

22. Excessive or inadequate refrigeration pipe length

When it comes to refrigerant pipework, efficiency decreases as length increases.  Therefore, you want to keep the refrigeration pipe run as short as possible.

However, a certain length of pipe run is still required as a minimum.  Smaller split systems generally require a minimum pipe run of ~1.5m, while larger wall split systems may require ~3.0m as a minimum.

Installing an aircon system with less pipe work than the minimum requirement specified can create a range of issues.  The system will not perform at its maximum operating level, and issues with noise or vibration can occur.  Furthermore, failure to adhere to manufacturer specifications voids the manufacturer’s warranty.

Each AC model will come with specific technical specifications, often outlined in the installation manual.  The best air conditioner installers will take note of the manufacturer instructions when installing your air conditioning system in order to avoid these issues.

23. Failing to keep out vermin

During the installation of a wall split or split ducted system, there is typically a need to make some entry/exit holes for pipework, electrical, drainage, etc.  This site can become like a pet door for unwanted pests such as insects, spiders, geckos, mice, rats, snakes, and many more.

It’s important that any holes made during air conditioner system installation are sealed properly as soon as possible during the process.  It is a mistake to leave holes long-term or even short-term, as they can quickly allow unwanted vermin enter.

A reputable installer will restrict hole-making to the bare minimum.  They will also most certainly seal new holes when carrying out new installations, and during changeovers unless otherwise specified for suitable reasons.

24. Incorrect wall controller location

A wall controller should be installed at a suitable height, often ~1.6m off the ground, to ensure the average user can comfortably reach it and see the display screen clearly.  While it can be moved up or down slightly, unfortunately the height of the users is not always considered.

Furthermore, wall controllers should be installed in a logical area in the room being served by the air conditioner.  If they can not be for whatever reason, then they should be clearly labelled.

Another failure with wall controller installation can be 2-fold; failure to provide or read the instruction manual, and failure to set ground rules around adjustment of the controller.  Staff incorrectly or sneakily adjusting the wall controller can cause endless temperature wars in an office environment!

As a result, an AC technician can frequently be called out and often blamed for the system not working properly.  Solution?  Install a lockable box around the wall controller, with key access by 1 suitably trained and reasonable staff member onsite only.

25. Misplacing thermostat and/or sensors

The location chosen for installation of an air conditioner thermostat and/or temperature sensors can often be messed up.  This can prevent an entire air conditioning system from working correctly and waste power due to excessive heating or cooling being called for.

Thermostats and sensors are designed to detect the temperature where they are located, and communicate with air conditioner units to call for more or less heating or cooling.  If the temperature detectors are installed too close to a heat source, they will inadvertently call for extra cooling and the AC will ramp up to provide this.  Direct sunlight can also cause excessive heat adjustment from an aircon.

This error may not be detected until someone questions the excessive power bill.  Alternatively, an air conditioning professional may be called in to see why the system doesn’t seem to be working as designed; excessive cooling in some areas, detracting from cooling in other areas.

26. Poor clean up

Unfortunately not all AC contractors leave a property in the same state, or better, than they find it in.  Some make the mistake of not cleaning up to an acceptable level.  Leaving behind significant dust, debris, scrap, and rubbish is not only unacceptable and damaging to property, it can be dangerous to the occupants (humans and animals).

Following any work onsite, the premises should be left as clean as it was found, if not more so.  Vacuum cleaners, spray and wipe, rags, rubbish bags, and other cleaning items should be standard in any AC technician’s work vehicle.

Furthermore, a good technician should leave your air conditioner in a clean state wherever practical, both inside and out.  Failing to do this can cause damage to air filters and other internal components.  If you’re not happy with the state of your aircon on completion of a site visit, don’t hesitate to speak up to the air conditioner contractor or their company.

Air Conditioner Usage

27. Incorrect set point

An incorrect set point is one of the most common air conditioning mistakes made.  This mistake goes back to the days where most people had no idea how a reverse cycle air conditioner works.  Occupants would often just turn their thermostat right down, assuming that this would cool an area quicker, with the reverse for heating.  However, this is not the case.

An average home air conditioner unit runs at full power or turns off.  Therefore, when the set point is low, the system continues to work at the same level but just works for longer.  This is true whether it has to lower the indoor temperature by 2 degrees or 20 degrees.

It is recommended to enter the set point to where you want the room temperature to be, not lower.  Amazingly, there is a 3% saving on AC running costs for every degree you adjust your thermostat or sensor set point.

Furthermore, humans have the inbuilt ability to adapt to hot or cold conditions relatively quickly (i.e. within 1-2 weeks).  So to save a little more on your power bill, maybe try and adjust the set point up/down a little to reduce the demand on the air conditioner and reassess after a few weeks.

28. Incorrect fan speed

Many people make the mistake of ignoring air conditioner fan speed.  However, it can make a big difference in terms of comfort levels and energy efficiency.

To get the indoor temperature down quickly, it is recommended to use high fan speed.  This is the most efficient way to cool down an area and reach the desired set point.  However, if humidity is the main focus such as on very humid days, then it is recommended to use low fan speed.

Fan speed impacts the time air spends travelling over the indoor evaporator/heat exchange coil.  When fan speed is high, air is simply cooled and blown out indoors.  When fan speed is low, the air is still cooled but there is also time for moisture removal from the air before it is blown out into the room.  At night, fan speed may be lowered to just maintain temperature overnight.

29. Using auto mode

Using Auto mode on an air conditioner is a common mistake that can easily be avoided.  The ideal setting on your home air conditioner is Heat or Cool, rather than Auto.  If you want to heat up the indoor space, select heating.  If you want to cool it down, select cooling.

When Auto mode is selected, and the temperature reaches set point, the system may switch between heating and cooling as the temperature fluctuates above/below the chosen set point.  This is not an efficiency way to use the device and can wear out certain internal components quicker than normal.  You will also experience blasts of hot and cold air intermittently.

To dehumidify, select the Dry mode (if available).  This will cool but also allow some air to just past through the indoor unit and remove moisture from it, reducing humidity in the indoor environment.

To circulate air, select the Fan mode.  This is suitable for cooler period at night and other times where air movement is required, without the need for heating, cooling, or dehumidifying.

30. Blocking supply air registers

Ducted air conditioning systems can be surprisingly sensitive to air flow changes made to any one of its multiple supply air outlets.  It’s quite easy to mistakenly close off too many outlets, or too much of any one outlet, and negatively impact the rest of the system.

Closing/blocking any outlet will change the flow of air around the system, positively to some areas but negatively to others.  To change the way air flows through a ducted aircon system, a full air balance is recommended to balance the air in one hit using a TSI Air Flow Hood.

AC vents blocked by furniture or curtains can also limit air circulation and impact system performance.  Unless you spend a lot of time huddled under your sofa, you surely wouldn’t want any of your AC vents to be obstructed.

31. Conditioning empty rooms

Rather than closing off unused supply air outlets, it is recommended to close off rooms that are not being conditioned.  This will avoid hot air entering the conditioned spaces or heat being wasted into unoccupied rooms.

Further improvements can be made by closing cupboards in conditioned rooms (or all rooms to be safe).  This means that even less space needs to conditioned overall, reducing demand and improving system efficiency.  Just remember to leave a small gap/opening to those rooms receiving the conditioned air to allow air circulation.  The average space under a door isn’t typically enough for optimal air recirculation.

Also ensure the unconditioned areas are switched off on the controller in the case of zoned air conditioning.  This is also important to help ensure the ducted aircon system is not being used excessively.

Air Filters

32. Incorrect air filter type

There are a wide range of filters types on the market; manufacturer, panel, pocket, pleated, v-bank, carbon, and HEPA, just to name a few.  The range is typically greater for commercial heating, ventilation, and air conditioning systems compared to home air conditioners.

Filters can also be categorised by media type; washable or disposable.  It can be a mistake to use disposable where washable are suitable, as you may literally be throwing away money whenever the filters are replaced.

Washable filters are the most common these days, at least where water is plentiful.  Disposable filters may be more suitable wherever water restrictions are in place, or where you cannot remove, clean, and reinstall the air filter/s as required in the case of washables.

33. Inadequate return air filter size/quality

Another common mistake with filters is incorrect thickness or patching them up haphazardly.  Despite the fact that there are clear Australian Standards relating to air filters in Australia, you would be surprised at the variation in filters use.

Suitable return air filter thickness depends on the AC type and application.  It must be thick enough to filter the air sufficiently before it reaches indoor unit, but thin enough to let enough air through.  Standard thickness range is from 9 to 90mm.

Patching a filter incorrectly is not acceptable by any means.  Air flow can be affected, and this is a major determinant of correct system operation and performance.  For the sake of a few dollars, an incorrect filter can cost you hundreds or even thousands in equipment damage.


34. Unsuitable return air grille location

Mistakes are often made in regards to return air grille and filter location (i.e. location where air is entering the indoor unit/AC system)Back in the day, return air vents were placed out of sight and even hidden in closets.  This is the opposite of there they should be installed.

There are many issues with having the return air grille hidden away.  Firstly, the air being sucked in may not be representative of the air temperature throughout the rest of the house.  The air may also be dusty/musky, causing the return air filter to block up faster without you realising it, decreasing air flow into the aircon system.

Furthermore, the grille may end up being covered by boxes and other items stored in the same location, as well as potentially being in an enclosed area, restricting air intake and decreasing system performance.  This puts strain on many AC components, causing premature equipment failure and reducing overall system lifespan.

35. Not enough filter cleaning

Without a doubt, one of the biggest mistakes with air conditioning is not enough filter cleaning.  Without cleaning, a filter can not do its job which is to literally filter the air entering an air conditioning system.

This mistake also decreases air flow into an AC unit, decreasing efficiency of the air conditioner significantly.  In fact, a dirty filter can increase the aircon energy consumption by up to 15%.

Dirty filters allow dust, dirt, hair, allergens, and other matter pass through to the indoor unit, causing build up in the indoor unit.  This further reduces system efficiency, promotes growth of mould and other microorganisms, and causes dirty air to circulate throughout your home or business.

It’s recommended to check filters at least monthly, clean seasonally or after any dusty activity (e.g. moving, renovating, major cleaning), and replace them when wearing thin or can see light through.  More tailored, system-specific recommendations may be made by a technician during a professional aircon service visit.

36. Too much filter cleaning

This may be a surprise to many, but cleaning filters too often can actually be a mistake.  Business owners in particular can get a bit concerned when AC contractors don’t clean every filter every month, but they may be doing this for good reason.  In the case of disposable filters, these should never be washed.

Washable filter media/material wear out over time.  Every time you clean the filter, the media wears away a little.  Washable filters are designed to handle routine cleaning, but they start falling apart at a certain point.

With excessive washing, and even with suitable cleaning, filters may not last as long as the air conditioning units themselves.  This is especially true in the case of ducted aircons and most commercial HVAC systems.

Cleaning air conditioning filter

37. Incorrect replacement frequency

Some people may suggest that filters need to be replaced every year, every season change, or even every month!  While it does depend on the filter type (washable or disposable), air conditioner application (residential, commercial, or industrial), and frequency of use (24/7, 50% of the time, or occasional), this is still highly unlikely.  99% of the time, filters just need routine checking and subsequent cleaning when required.

On the flip side, some filters are used well past their serviceable lifespan.  This allows dirt and dust to pass by the filter media, affecting system efficiency, cleanliness of internal components, and the health of the AC system and humans.

It’s a fine line between premature and overdue replacement of filters.  An experienced air conditioning contractor would be able to tell you if/when your aircon filters need replacement.

DIY Aircon Service

38. Failing to perform general AC maintenance

Firstly the biggest mistake when it comes to DIY air-conditioning servicing is simply not doing it.  Air filters aside, general AC maintenance should be carried out on a home air conditioner at least once a year, if not two or three times.

In a commercial setting in Australia, HVAC servicing is recommended monthly.  This is over and above routine filter checking and cleaning.

There are plenty of checks, tests, and tasks that you can do yourself to help maintain your air conditioning system.  This allows your aircon to perform at an optimal level, allows minor issues to be detected before they become major, and helps extend the lifespan of the air conditioner.

39. Failing to clean indoor components

Just like filters, other indoor components of your air conditioning system require routine checking and cleaning when they become dirty.  These include the fascia, drain, fan scroll, barrel, coil, and supply air outlets.  Once big mistake is not cleaning these with water/damp cloth when needed.

Some of these components can be cleaned by yourself, provided you fully understand where and how electrical components can be of harm.  You also need to ensure there is safe access for cleaning, and you are not at risk of falling.  The safety of you and those around you should be the number one consideration!

Furthermore, it pays to understand where it is safe for water to come in contact with an indoor air conditioner unit.  The last thing you want to do is cause damage to the very air conditioner unit you’re trying to clean and maintain.  The safety option is to enlist the help and service of a professional aircon technician when it comes to AC cleaning.  It’s better to be safe than sorry in regards to the health of yourself, your family, and the air conditioner itself.

40. Inadequate drain clearance

Another common mistake is failure to maintain, clean, treat, or fully clear air conditioner drains.  As a result, condensation produced as a normal part of the refrigeration cycle can back up and/or overflow out of the designed drainage system.

AC drain blockages can occur when an array of matter builds up in the drain line.  Such matter includes slime, sludge, mould, insects, and even pieces of insulation.  Special drain condensate tablets can help slow the growth of algae which is a common contributor to drain sludge and blockages.

Once a blockage occurs, it needs to be vacuum out with a wet/dry vac and flushed with water.  This will clear most blockages and restore a normal drain to full function again.  However, if water continues to leak where it isn’t supposed to, or you see any ice building up, it’s time to call in an expert as a more serious issue may be present.  Your need to act quickly with this, to prevent or at least minimise damage to the area surrounding the drain.

41. Incorrectly applying liquids

Liquid, either the wrong type or incorrectly applied, can cause great damage to any electrically-based appliance.  This is especially true for modern day air conditioner units that are electrically based.

Any type of moisture, particularly in excess, can easily damage aircon parts such as PC boards, capacitors, soft starters, transformers, and motors.  Like getting water on your non-waterproof phone, computer, or TV, the device could not be expected to work property after such damage.

Even the condenser coil and compressor can be damaged by incorrect or excessive liquid.  The refrigeration cycle is designed to be a closed system.  If any moisture enters the system, it is considered a non-condensable.  As this moisture can not be condensed by the condensing unit, it builds up and cause issues.  Impacts include metal corrosion, damage to the copper plated condenser coil, chemical damage, and compressor failure.

42. Not cleaning/correcting/clearing for outdoor unit

Similar to an indoor unit, certain work can be done to an outdoor condensing unit that people fail to consider.  Coils can be cleaned, fins can be combed/straightened, and the area around the unit can be cleared.  Cleaning or combing of the condenser coil is best left to the professionals, but clearing is fine to do yourself.

The condenser coil outside absorbs and releases heat.  This heat transfer is affected if coils are covered in dirt, grime, leaves, pet hair, or any other matter.  Hail-damaged coils also have reduced area for heat transfer, impacting system performance and efficiency.

Suitable clear area around the outdoor unit ensures adequate air flow into/out of the unit and also helps prevent build up of matter on the coil.  Organic and inorganic matter must be cleared; trees, bushes, weeds, pet beds/blankets, boxes, screens, bins, equipment, tools, bikes, etc.  Generally, you want to always ensure at least 300mm clear around an outdoor unit.  At the front you need about a metre, while at the back may be a little less than the general rule of thumb.  However, the more the better.

43. Inserting foreign objects

Heating and cooling contractors can find all sorts of foreign objects mistakenly entered into air conditioning units.  Screw drivers, sticks, rulers, brushes, and all sorts of other items (including fingers) are inserted into aircon units and associated components.  This rarely ends well (especially for fingers…).

Foreign objects can easily damage AC components such as fan blades, motors, scrolls, coils, drains, flexible duct, supply air registers, and return air filters.  This damage can be anything from minor scratches through to complete system failure as subsequent repairs may not be financially viable.

Apart from the air conditioner, harm can also occur to the person inserting the foreign object and those around them.  For example, fan shards can fly out and hit family members, refrigerant gas can leak out and poison pets, and the list goes on.  Best not to insert anything into an AC unit unless you know 100% what you are doing – leave this for the trained professionals.

44. Relying on self-diagnosis

People often make the mistake of self-diagnosing a commercial or home air conditioner without a complete understanding of how the system works and/or what an error code (if applicable) truly means.  It’s a bit like googling your health symptoms and making a self-diagnosis without the knowledge and experience of a medical professional.

Some issues may be suspected based on personal experience or anecdotal evidence.  In some cases, the diagnosis could be correct.  But in most cases, it is either not correct or does not tell the complete story about what is going on with the air conditioning system.

It really pays to calling in an expert when it comes to diagnosing issues with your aircon.  Furthermore, the professional can actually assist with complete repairs or proceed with the most suitable course of action in relation to your AC system.

Professional HVAC Service

45. Infrequent professional service

Even if your AC is working well, regular heating, ventilation and air conditioning (HVAC) maintenance appointments are a must and all-too-often neglected.  A professional air conditioner service can help to increase efficiency, lower your energy bill, increase the lifespan of your system, and prevent or address issues before they become more costly.

It’s often recommended to have your home aircon checked over by a professional at least once, if not 2-3 times per year.  This type of preventative maintenance is often over-looked.  However, it could actually save you more in the long run, as discussed previously.

For businesses, is a requirement of Australian Standards (including 3666.2.2011, 1851.6.1997, 2467.13.1997, HB32:1995) and state-based Work Place Health and Safety Acts that commercial air conditioning equipment/plant be inspected on a monthly basis in order to maintain an acceptable commercial environment.  However, the decision to follow these guidelines ultimately lies with the business/owner.  A good commercial company would be happy to offer an HVAC maintenance proposal upon request.

46. Poor timing

Is highly recommended to plan ahead and book your professional air conditioning service outside of peak times.  This is for many different reasons that help you and the AC company.

Outside of peak season, most aircon companies will have better availability and may offer lower off-peak pricing.  Furthermore, the attending technician may have more time and headspace to focus on your air conditioner as their days may not be as busy.  Suppliers are also quicker to respond with part details and dispatch parts, if needed, as demand is lower.

Furthermore, if any further work is needed then it can occur in a more timely, price competitive, and relaxed manner.  There will also be time for the system to be brought up to scratch, if needed, before the peak of summer or winter.  All-in-all, many reasons to plan ahead and booked your AC service nice and early!

47. Incorrect service type

There are many different types of air conditioning service that can be booked.  They may be referred to in many different ways by air conditioning companies; major/standard/minor, gold/silver/bronze, etc.  All-too-often people make the mistake of booking a minor service when in fact a major aircon service is needed.

It’s important to discuss your service needs upfront and ensure the service you book the the most appropriate for your air conditioner, as far as reasonably practical.  You don’t want to waste your time or money by having to re-book another service visit and/or receive a quote for further work.

A good air conditioner service company will have some flexibility in their service structure.  For example, certain technicians will have the additional training and carry the specialised chemical cleaning equipment, in case needed.  Alternatively, there may be an acceptance of halting work onsite until the most suitable AC service can be arranged.

48. Not considering chemical cleaning

Over and above routine cleaning and servicing, certain components of your air conditioning system can be chemically cleaned.  A common mistake is discounting this option before even considering it.

Internal components that can often require chemical cleaning include the fan scroll, barrel, coil, and drain in a wall split unit, and indoor coil and drain pan in a ducted aircon.  Specialized equipment, training, and food-grade safe AC cleaning chemicals are required to carry out this work.  There is also an option for full ductwork cleaning, which takes many hours for a highly experienced duct cleaning team to complete.

There are a lot of people advertising air conditioner cleaning, however consumer beware!  Currently no specific licencing is required to be able to promote and carry out aircon unit cleaning.  If any issues are found with your air conditioner, you may have to call in an actual HVAC technician if your cleaner is not suitably qualified.

49. Wrong company/technician

Many companies promote the fact that they service air conditioners.  However, in reality there is a wide range of qualifications and backgrounds that so-called “air conditioning service technicians” have.  Don’t make the mistake of booking the wrong man or woman for the job.

Firstly, you want to book a technician that has an ARCTICK licence to look at your air conditioner.  This is a Refrigerant Handling Licence (RHL) that must be held by anyone carrying out work on refrigeration and air conditioning equipment.  Handling common AC refrigerants without an RHL is an offence.  National regulations are in place to regulate this requirement.

You also want to book someone who can complete all aspects of your air conditioning service and repairs, in case needed, rather than someone with an electrical background only.  If the attending air conditioner contractor is not fully qualified (aka a Refrigeration Mechanic/HVAC Technician), their ability to check and truly service the aircon, let alone complete any additional repairs, is severely limited.

Air Conditioner Features

50. Not having/using a programmable thermostat

Not having or using a programmable thermostat on your air conditioner is a big mistake.  Auto-adjusting the temperature up or down a few degrees, just to take the edge off any extreme ambient temperature, can save you hundreds or even thousands in annual electricity costs.  If fact, there is up to 3% in savings for every degree you adjust the thermostat.

With today’s technology, you may disregard a programmable thermostat as a boring, old-fashioned feature.  However, while common, they are still not standard with every air conditioner.  It’s well worth checking, so that you have the power to program temperatures for certain times of the day.  They allow you to manage indoor climate control without constant attention.

Thermostats are also not created equally.  Advanced thermostats, such as Google’s Nest thermostat, actually learns your home’s rhythms and shifts to accommodate repeated schedules.   Smart thermostats also allow control, including temperature adjustment, via an App using Wi-Fi.  If you don’t have a programmable thermostat, now is the time to upgrade and enjoy the many benefits.

51. Not setting timers

Similar to programmable thermostats, timers come standard with certain air conditioners but people still make the mistake of not utilising them.  They are worth having and using to manage indoor environment, not only when out of the house but also overnight when climate requirements change.

Using timers to manage the running of your air conditioning system/s can save you decent money, as heating and cooling your home uses significant energy.  The same goes for businesses, where the savings may be even more significant depending on the size of the commercial premises and type of aircon in place.

Set and forget timers can really help those of us who have enough to think about when racing out the door without also having to try and remember to adjust the AC!  Heating and cooling timers can be pre-set, so you can relax and know your aircon is under control.  This assists with the climate control of your home so you can focus on the many other things going on in life these days.

52. Not utilising Wi-Fi

If you haven’t programmed a thermostat or set up a timer on your air conditioner, then a Wi-Fi-enabled air conditioning set up can save the day.  This is often an added extra that many make the mistake of disregarding before truly considering it for their work or home aircon.

Wi-Fi set up with your air conditioner allows you to make adjustments from the comfort of your couch, bed, or when out and about.  It’s worth stopping to think about how this would work for you; laying in bed, one cold winter morning, and being able to take the edge off the air with some remote heating control before even having to remove the doona.

Smart phone applications make adjusting your home air conditioner simpler and easier.  Imagine heading home from work on a hot day, and being able to pre-cool the house to avoid walking into what feels like an oven.  It also allows you to monitor and adjust the climate for precious pets or the children when home on school holidays, all while you are at work.

53. Not having/using sleep mode

Sleep Mode or Night Mode is an under-rated, under-utilised, energy saving feature on many modern-day air conditioners.  It’s worth having and using this economic heat/cool setting to automatically adjust temperature overnight, as the name suggests, to help promote a better night’s sleep.  The relationship between air conditioning and sleep is well-established

To commence and maintain restful sleep, the human body needs to drop its core temperature by a few degrees.  Sleep is hard or even impossible to start without this temperature drop.  Meanwhile, excessive cooling can cause discomfort and contribute to a range of negative health outcomes.  This mode can help achieve a happy medium, especially useful for sensitive sleepers.

Air conditioner Sleep or Night Mode will automatically increase temperature gradually (i.e. 0.5 – 1 degree per hour), up to a maximum of 3 degrees.  This change isn’t noticed while sleeping but does significantly reduce the aircon workload.  This can contribute to significant savings over time, in terms of both your hip pocket and air conditioner lifespan.

54. Not utilising self/auto clean functions

It is becoming increasingly common for air conditioners to have a Self Clean or Auto Clean function.  However, this isn’t much good if consumers don’t bother to use this rather handy feature.  If you do have this feature, it’s recommended to use it every 1-2 weeks depending on where you live.

A self/auto cleaning function typically cleans and dries the inside of an indoor AC unit.  This is useful because the indoor aircon unit becomes quite moist due to moisture production during normal operation.  This moisture creates the perfect environment for micro-organisms, mould, mildew, and the like to grow.  It can also causes corrosion and rust of internal components such as the evaporator coil.

The self cleaning function helps keep the growth of nasties at bay while improving the indoor air quality.  It also improves the operation of the air conditioner and supports it working as designed.  It’s important to note that this supports but does not replace regular aircon filter washing, routine maintenance, and professional servicing and cleaning where required.

55. Failing to set/action/reset reminders

Another useful feature that is a mistake to ignore is service/action reminders.  Many air conditioners, particularly ducted aircons, have a service or filter cleaning indicator that will show up after certain number of hours run time (e.g. 200-250 hour).  This is a generic reminder that the filters need cleaning.  In a business environment, this may signify time for commercial aircon servicing.

Once the cleaning or servicing has been carried out, the reminder needs to be reset on the panel.  It’s important for this to happen straight away to ensure accurate timing between maintenance intervals.

Resetting the reminder also prevents it coming back before cleaning is actually required.  This can occurs if it wasn’t showing up at time of attention.  Remember, like any reminder, this feature is pointless if it is reset/cleared without the required action actually taking place.

Associated Paperwork

56. Not checking with Body Corporate/Council

When looking to install an air conditioner, or undertake any significant AC modifications, its not uncommon for people to make the mistake of going ahead without the required approval.  This can result in costly removal/adjustments being required, and often a waste of the original install or modification investment.

For Body Corporate approval, you will need to check specific requirements for your property and complex.  There is a wide range of requirements for obtaining approval.  Most require a copy of the quote, many require a diagram showing the layout, while some even require meeting attendance and more detailed explanations.

For Council approval, most applications can commence or even be completed online.  The degree of difficulty in approval will depend on what zone you are in and the specific approval you are seeking.  While is can be painful, it is worthwhile undertaking the required process of approval ahead of time.

57. Not having formal agreement/fixed quote

While we like to be able to trust people, please don’t make the mistake of relying solely on a hand shake or verbal agreement when it comes to air conditioning.  Unless it is a well-trusted family-member or friend, not having a formal agreement in place can cause headache if things go pair-shaped.

Firstly, you should be able to obtain a free quote for air conditioner installation.  This way everything can be set out and negotiated before the aircon is installed.  This should also outline all inclusions, exclusions, terms and conditions.  This allows a truly informed decision to be made.

For repairs, any reputable AC company and/or technician will outline costs involved and not proceed without approval.  This may be via confirmation text, email, or customer signature.  This agreement is designed to protect the customer, the technician, and the company.  No one likes nasty surprises, so it pays to be upfront with costs and ensure complete agreement before work is carried out.

58. Not checking installer qualifications

A lot of businesses advertise air conditioning installation, but not all businesses are necessarily fully licensed.  If your air conditioner is not installed by a licensed contractor, apart from causing issues down the track, it can void the manufacturer’s warranty.

It really does pay to check that your air conditioner is being installed by a suitable tradesman and/or company.  Firstly, you can check for the relevant Refrigerant Handling Licence (RHL) at  You can also ask to see the relevant Electrical Licences for piece of mind.

Furthermore, for any ducted aircon install, large-scale split install, or significant repair work, it pays to check relevant Building Commission licensing.  For example, in Queensland, any work over $3,300 requires the appropriate class of Queensland Building and Construction Commission (QBCC) contractor licence.

59. Not reading user manual

Many of us don’t like reading instruction manuals.  The same is true of air conditioner user manuals, that many of us make the mistake of never referring to.  Men are even less likely to read or refer to manuals than women (no surprises there!).

When you purchase a new aircon, it comes with a manual of some sort; Operations Guide, Owner Instructions, or User Manual.  This outlines operating instructions for your particular model of AC unit as well as key features and ways to care for it.  These instructions help ensure correct usage, help optimise performance, assist with maintenance, and promote longer life of the equipment.

If you don’t have a copy of the manual, contact your air conditioner installer for this.  Alternatively, you can usually obtain a copy online.  Just jump online, type in the model number, and there should be a copy of the guide towards the top of the search results for you to review/download/save/print for easy reference.

60. Not retaining receipt/s

Some people are naturally better than others at organising their paperwork.  Like any major purchase, you want to keep the receipt and any associated paperwork somewhere safe or easily accessible in case required during the warranty period.  This includes for the installation and the air conditioner itself (if purchased separately).

In the case of air conditioning, home air conditioner units typically come with a five year manufacturer’s warranty.  This is a long time to keep paperwork.  Electronic copies are handy in a long-standing email account, or paper copies in a well-organised filing cabinet.

If not retained yourself, all may not be lost in the unfortunate event that warranty repairs are required.  A reputable supplier or AC install company should be able to provide a copy of the receipt at least within the five-year period.

61. Not registering products

A lot of products these days ask for you to register them online.  In the case of air conditioner products, it can be a mistake not to do this if the option is presented to you. 

Registering your air conditioning system may prevent you needing to find paperwork in the unlikely/infrequent event that warranty repairs are required.  Even if you forget your password, your email, name or even street address may be all the manufacturer requires to recognise your aircon.  If/when recognised, repairs may happen without you having to do anything else.

Some products also offer extended warranty if you take the time to register your air conditioner.  For example iZone offer a 10 year parts warranty on their registered ducted zoning equipment.  LG also offer extended warranty on certain compressors for up to 10 years if the equipment is registered.

62. Not checking home insurance

It pays to know what you’re covered for under your home and contents policy or business insurance.  This is even more true when it comes to causes of damage that can impact your air conditioning system.  Don’t make the mistake of being in the dark about your specific coverage.

Insurance policies come in all shapes and sizes.  Items and causes of damage covered vary dramatically.  It’s worth being aware of causes of damage relevant to your air conditioner.  Common types of damage include motor fusion/motor burn out, storm damage, flood, electrical surge (non-storm based), fire, animal damage, and even accidental damage.

When reviewing or renewing your policy, consider your property location and likelihood of all possible events.  Do you often see geckos running around and think animal damage is likely?  Do you have an AC unit in a certain location at risk of accidental or intentional damage?  Taking out the most suitable coverage and knowing the inclusions could save you thousands in out-of-pocket expenses down the track.

Air Conditioning Assistance

63. Excess heat load inside

Many people make the mistake of unnecessarily straining their air conditioner.  Increasing the heat or cool load indoors when the ambient temperature is high is one key example.  Heat/cool load typically refers to the amount of heating/cooling a room or building needs to maintain the temperature set indoors.

Heat/cool load depends on many different factors, but there are ways to decrease this demand.  Cooking outside in summer is a great example.  Also running appliances in the early morning/evening helps to decrease load.  Turning off non-LED lights and bathing with extraction fan on are more simple examples that can reduce the demand on your AC system.

Increased heat/cool load makes your air conditioner work even harder at a time when it may already be stretched to the limit.  If the system is getting on in years, then efficiency will typically have decreased.  Any added strain could then push the aircon over the edge, resulting in individual component or complete system failure.

64. Not having/using ceiling fans

Don’t make the mistake of thinking you don’t need fans with aircon in place.  Fans assist and enhance the air conditioning effect in your home or business.  They are one of the cheapest and effective ways to assist your air conditioner.

Any type of fan, especially ceiling fans, helps circulate cool air throughout your home.  This results in lower temperature throughout.  Air movement enhances the cooling effect felt by people indoors and decreases demand on the aircon system.

Many ceiling fans spin both ways; one way for summer to increase air flow, and another way for winter.  The direction can typically be changed by a reverse switch on the base of the fan, near the motor.  Blade design impacts which direction is which, so check out the manual for your fan, or just stand underneath it while on high for each setting to discover which is which for your fan.

65. Not considering roof/attic fans and whirlybirds

Over and above ceiling fans, you don’t want to make the mistake of ignoring the benefits of attic exhaust fans (power or solar) or whirlybirds (mechanical or wind-driven).  These can assist in lowering in-roof and in-room temperatures, reducing aircon demand.

These devices are designed to suck out heat in the roof space.  This lowers not only ceiling but whole property temperature.  This is how it reduces demand on the air conditioner and facilitates a cooler indoor environment.

Roof exhaust fans and whirlybird are particularly useful in warmer climates.  The sun can easily heat up a roof space to 60-70+ degrees celsius in summer, which has a significant impact on temperature throughout a building.  This is one of the reasons why sensible air conditioning companies limit ducted servicing/repairs in summer to the early morning; no technician wants to or should be crawling around in such temperatures.

66. Failing to consider windows and treatments

It is easy to make the mistake of failing to consider window number and location when looking at air conditioning in a home or business.  Investing in suitable window treatments that can assist an air conditioning system is also not considered as often as it should be.

Firstly, large windows can significantly impact heat/cool load indoors.  South-facing window in particular can soak up the sun.  Remember to consider window location and sizing when calculating heat/cool load for an air conditioner initially.

Secondly, keep windows covered during the heat of the day wherever possible.  For natural light, consider the array of window treatments available.  This includes tinting, sheer curtains, shutters, and tilting horizonal blinds, just to name a few.

67. Not considering/installing insulation

It is recommended to consider the insulation in your home when investing in air conditioning.  Don’t make the mistake of investing in a new air conditioner, only to have it’s effects diminished by lack of insulation.  If the impact is significant enough, the new aircon may no longer be suitable for the area that it is designed to heat or cool.

Ceiling, wall, and floor insulation all have a significance impact on temperature control in a building.  For example, a properly insulated attic space can save up 50% on home heating expenses.  So, not only is the impact of insulation felt indoors, but it is also felt in your wallet.

Insulation is often straight forward and cost-effective to install, if not already present.  As mentioned, it has subsequent impact on your power bill.  Insulation should simply not be ignored.

68. Neglecting pest management

People rarely stop to consider pest management in relation to air conditioners.  There are two main factors when it comes to animals and aircons; We need to consider pest management to protect the AC units, but also air conditioning can help protect us against unwanted animals.

If an air conditioner is too close to animals’ natural habitat, the risk of animal damage to the AC unit is high.  Such damage is common when animals such ants, roaches, geckos, lizards, frogs, snakes, mice, rats and even possums interact with the aircon unit.  Domestic pets can also cause damage, but few people would consider these pests.

On the flip-side, air conditioning can help keep out unwanted animals.  By having an operational air conditioning system in place, windows and doors can be closed.  This prevents unwanted visitors such as flies, mosquitos, and all other animals mentioned above, from sneaking in through openings.  Furthermore, a routinely maintained air conditioner can control dust mites which otherwise thrive in warm, damp, dark conditions.

69. Neglecting the garden

Letting the garden go a little is not uncommon with our busy lives, but this neglect is a big mistake around air conditioner units.  Don’t let this routine maintenance task lapse and result in damage to your aircon.

Strategically planted landscaping can help shade your outdoor unit, windows, and parts of the home, which reduces demand on the air conditioning system.  However, if too close to the home or overgrown, greenery can provide a home or invite animals around that can damage your AC.

An overgrown garden can also start to grow into the AC unit, wrapping around internal components and/or causing electrical issues.  Having items so close to the condenser also reduces airflow, causing reduced efficacy, performance, and potentially permanent damage.  To avoid such issues, assess and maintain all trees, bushes, grass, weeds, garden beds, vegie patches, and any other living matter near your air conditioner units.

70. Storing items around AC units

Gardens are not the only issue when it comes to mistakes made around the condensing unit or air conditioner as a whole.  It’s relatively common for people to make the mistake of storing items around an air conditioner with negative impact.

The outdoor condensing unit needs space all around it to work properly.  Any items placed too close can reduce air flow and system efficiency.  In general, there needs to be at least 1 metre clear in front of the unit and 300mm clear around a unit.  The area behind the unit is may be slightly less, depending on manufacturer specifications.  However, the more space the better.

Any items placed too close to an indoor or outdoor unit can reduce air flow and system efficiency.  Such items include furniture, plants, screens, covers, boxes, fences, bins, gardening equipment/tools, bikes, pumps, and pool chemicals/equipment.  Basically, anything within the recommended clearance zone around the unit should be removed to protect your air conditioner and ensure maximum performance.

There are so many different mistakes that can be made with air conditioners.  Errors can be made at all stages of an aircon lifecycle; selection, purchase, installation, usage, maintenance, assisting, and replacement at end of life.

Air conditioning technicians are trained to avoid and help advise on these issues, which is why their skills and experience can not be underestimated.  Failure to appreciate a decent heating, ventilation, and air conditioning (HVAC) technician may be mistake number 71!

This article has outlined just some of the most common aircon mistakes.  Hopefully you have picked up some tips and now know what to look out for with your own air conditioning journey.

When you start a small business, or you are in charge of one, you will have to make many important decisions.

One of those decisions is how you are going to handle the air conditioning in your new location.  There are plenty of options for you, but you need to think strategically.  Take into consideration that you are just starting, so investing a lot of money upfront may not be the best idea.

The most common air conditioning system for a business is ducted air conditioning that usually gets installed in the roof.  But if you want something for a small business, i.e. smaller place but want it to be equally effective, then you should consider acquiring ductless air conditioning.

What is ducted and ductless air conditioning?

Ducted air conditioning works with air conditioning grilles/ducts.  Air is expelled through them and the supply air outlets are distributed around the ceiling.  The indoor unit is connected to an outdoor unit via refrigeration pipework and interconnect cable.

In comparison, a ductless system provides separate heating and air conditioning without the need for ductwork.  You can also combine multiple indoor units to create a multi-zone system.  Indoor units can include wall split units, floor-standing units, ceiling-mounted cassettes, and under-ceiling split units.

Advantages and Disadvantages of Ducted Air Conditioning

Currently, many domestic and commercial buildings have the pre-installation of a ducted air conditioning system.  This would be an advantage when choosing ducted over the other AC types available on the market.

To have ducted air conditioning in your office, your office will need to have these ducts, through which the hot or cold air from a single unit will circulate.  If you don’t have these ducts, then it can be rather expensive to install initially.


Ducted aircon usually enhances the aesthetic of rooms in your office as you will not have to have a large device inside each of these spaces.  Also, the bulk of the system will be covered or hidden behind the ceiling, so people will hardly notice it is there.

Furthermore, ducted units are highly effective if you need to cool many rooms at the same time.  Also, by having a single outdoor unit, maintenance costs can be lower.


In many cases, you will not be able to choose which room to air condition.  This is because ducted devices, without a separate zoning system installed, constantly pump out air when switched on.

The air will come through the ducts and out in all the rooms where there is a grille installed.  This can make you spend more on your business energy bill than you need to.  You have enough expenses already, without adding more.

Also, if your office does not have ductwork or drainage already installed, the investment can be reasonably high if you have to carry out remodelling works.

Ductless Air Conditioning

Advantages and Disadvantages of Ductless Air Conditioner

The first thing you should know is that these devices can have an amazing air conditioner function.  With this, you will be able to obtain a far more comfortable working environment.

There are a range of options available.  For example, the silent ductless portable air conditioner is very easy to install and you will not have to do any expensive renovations or installation.


The main advantage of ductless AC are devices that save half the electricity consumption compared to other air conditioners.  You can switch off units in rooms that aren’t in use rather than continue to heat or cool the whole workplace.

Remember that traditional HVAC systems sometimes develop leaks in the ductwork that can reduce the efficiency dramatically.  You can avoid this problem entirely with a ductless air conditioning system.  Also, they do not usually require as much maintenance, saving you money in the long run.

Constant air circulation by an air conditioner, plus its ability to filter the air, helps to improve breathing.  Ducted AC units can be some of the quietest options of all with fast installation, so you can start operating your new business as soon as possible with no distraction.

Last but not least, you will save a lot of space with these devices.  This makes ductless aircon a great option for a typical small business premises.


The efficiency of ductless AC units can decrease in places where humidity and temperatures are very high.  Also, the air conditioning may not reach everywhere in larger places.

Also, ventilation cannot be integrated into a ductless system like it can be with a ducted system.  Unless you buy the high end Daikin US7, outside air cannot be brought into a central location like it can with ducted HVAC.

Furthermore, you typically can’t integrate humidifiers, dehumidifiers, air cleaning, or air purifiers with ductless air conditioning.  This is compared to ducted air conditioning where you can find these features.

Why ductless air conditioning is beneficial for your business?

Ductless aircon can be ideal for a new business when starting from scratch.  For example, you do not need to install any ductwork.  This will save you time and money, as well as preventing a more complicated installation and maintenance.

Also, it makes it easier for you to control which room you want to air condition.  It is also easy for workers to manage the devices and adjust the temperature to their needs. Furthermore, this will save you money as there are less heat loss and heat gain with a ductless system.

It’s modular, which means that if you need more heating or cooling or your office expands, you will just need to acquire other ductless air conditioner units.  Compare this to the cost of installing more ductwork and materials for the new rooms, if even possible with ducted air conditioning.

Turning air conditioning thermostat

How to choose?

Choosing an air conditioning system will depend on many factors.  Factors are linked to the characteristics of the place where you are going to install AC and your specific needs.  These include how many rooms you want to air condition and if you want to cool down/warm up with the same device.

Also, you have to take into consideration how much are you willing to spend on your air conditioning as you can also opt for air conditioning without installation.  This is suitable for consideration in places where temperatures are not so high.

Remember that buying the best air conditioning for your business is an important decision, so please do not hesitate to contact us in case you have any question or need any advice.  We can help find the best solution to match your business needs.

Window air conditioning units are a simple, easy-to-install solution for keeping a room cool.  It is the simplest of the many direct expansion (DX) systems available.

By installing a window air conditioner you can save a lot of money.  If you’re only looking to cool a couple of rooms, something like a central air conditioning system may not be a suitable use of money and resources.

The best thing is that your window air conditioner unit should only take a matter of hours to install.  Also, when the summer heat is over, units may be easily removed for storage.

Similarly, when you move to a new house, you may be able to pack up and take the unit with you.  This is a great option in a rental property or for commercial tenants.

In the following article, we will present you with a guide for the correct installation of a window type air conditioner as well as outline their benefits.

What are the benefits of a window air conditioner?

Window air conditioners are still one of the most popular types of air conditioners out there.

For many people, these devices have become the only cooling system in their home or office.  But, what are window air conditioner benefits?


The smallest box unit models are the cheapest ones, while air conditioners with large cooling capacities can obviously cost a little more.  It depends on your needs but they can still be some of the cheapest air conditioner units on the market.

If you live in a rented home and you do not own the place, and the owner will not install any air conditioning for you, one solution is to install a room air conditioner (RAC).  This is logical as your investment is limited and it may not worth installing a more expensive air conditioning system.


Many units these days have variable digital controls instead of simple high and low settings.  Therefore it’s important for you to know how to choose an energy-efficient air conditioner.

Units with energy-saving switches provide further assistance in reducing utility costs.  Also, compared to whole-house ducted aircon, room air conditioners are very cost effective if you are only looking to cool one or two rooms.

Easy to buy

Window and room air conditioners are easy to find instore if you are planning to buy one.  Also, you can find them in online stores.  Buying them is as easy as a trip to the store or a few clicks online.

Easy installation

Unlike other cooling systems, such as central or large DX air conditioning systems, installation of window air conditioners is fairly straightforward.  Most people can do it without any prior experience or knowledge.  You don’t need a fully qualified air conditioning installer for this one!

How to install a window air conditioner?

Measure the room

Window air conditioning units come in various sizes and cooling capacities, so it is important to choose one that best suits the given room.  Firstly, check the measurement of the room.   This information will allow you to work out the area the unit will have to heat or cool.

If the room is unusually hot or cold, you can adjust the capacity (kW) of the unit accordingly.  Other factors that affect the performance of the window air conditioner are the number of people in the room and the size of the door/s to other rooms.  These are just some of the things to consider before buying a unit.

Once all factors have been considered, you can then work out what size air conditioner you need.  You can then move towards the fun part; buying a window air conditioning unit.

Choose a window

After choosing the room and AC size, you have to identify the window in your room where you want to install the window air conditioning unit.  Then measure the width of the window and the width of the air conditioner to ensure the unit will fit.  It’s wise to know the space available before buying the box unit!

If the window is too large, don’t worry too much because many window AC units come with an accordion-shaped panel to fill in the gap.  But if the window is too narrow, you will have to buy a smaller window unit or consider a through-the-wall install.

Keep in mind that window air conditioners come in two versions: one for double-sash windows and another for casement windows.  Some units are not interchangeable and you will have to make sure you have purchased the correct version for the type of window in which you want to install your air conditioner.

Check your window

Most units are designed to fit various types of windows. When choosing a window to place the air conditioner, keep safety in mind.

If you notice that your window frame is unstable, it is recommended to fix this problem first. Once everything is in order, you can proceed to place the window air conditioner.

Place the window unit

Once you have the window air conditioner ready, it’s time to install it.  Carefully remove all parts from the box and assemble the unit as directed in the instructions.

Most window air conditioners require you add additional components, such as flanges and accordion-style panels.  If your package comes with screws, use your screwdriver and insert them where needed.  If not, you will need to purchase them separately before starting the installation process.

Insert the air conditioner in the window

For this step, may need a friend or family member to help you because window air conditioners are heavy.  Open the window where you are going to install the unit.  If your air conditioner came with waterproof tape, run it along the windowsill.

Although these strips are optional, they help protect your unit from any damage that may occur during installation and removal.  They also prevent cold air from escaping.

With the help of your friend, lift and place the air conditioner on the bottom of the window frame.  While your helper holds the unit in position, proceed to the next step.

Adjust the window

Carefully adjust the window frame until it rests behind the top flange of the air conditioner. At the same time, make sure that the bottom flange fits well with the windowsill.

Install the angle brackets

Your unit should come with two angle brackets. These brackets are essential as they lock your window frames preventing the unit from falling.  To install the brackets, place one on each side of the top of the window frame that supports the air conditioner.

One of the angle brackets will usually fit into the inside slot of the window, while the other will rest on top of the window frame.  Put these brackets in place, using your screwdriver and the included or purchased screws.

If the wood is too hard, you may need to use a drill to create a starting hole and tighten the screws.

Old Window Air Conditioner

Seal the window gap

The last step in the window air conditioner installation process is to create a seal that blocks the gap between the upper and lower frames.

You can do this with an insulating foam strip.  Your window air conditioner kit should include one.  However, if it doesn’t, you will need to buy an insulating strip.

Push the strip where the bottom window frame meets the top one.  If the strip is too long, use a utility knife to cut it to the correct length.  Once the foam strip is snug, you are done installing your window air conditioner.

Now all you have to do is plug it in, turn it on, and enjoy.

If you want to get the most out of your air conditioner and extend its lifespan, you should perform regular maintenance to your system.

The first step is to clean the aircon filters. An air conditioner filter is a removable part often made of nylon. Its function is to filter the air that enters the unit and clean it by trapping dirt and a degree of microparticles including dust.

Air conditioner filters tend to become clogged mainly due to dust particles. If they become partially or fully blocked, this can cause problems such as motor overload, overheated components, compressor floodback, and/or dripping water.

Furthermore, if you don’t clean the filters regularly, your aircon will have reduced performance, poor energy efficiency, and its life span will reduce. The excess dust particles will also affect people in the home or building suffering from allergies.

At this point, you may be wondering, “how do I clean my aircon filters?”. Well, you can pick up some tips here to do it yourself before calling in the experts for regular maintenance.

How to clean a ducted filter?

The most effective way to maintain an air conditioning system is to clean the filters regularly.  This is also a critical way to help ensure a healthy environment in your home or business; especially if you have a ducted aircon system where the same air is circulated around and around.

Ducted air circulates through the building and it is blown out through outlets in every room.  The air is then sucked back into the aircon system, and the cycle repeats. In this way, given the cycle of the airflow, the cleanliness of the air largely depends on how clean the filters are.

Remember that a filter prevents dust and airborne particles from recirculating indoors. If filters are dirty, further particles cannot be captured by them. This will cause dirt to enter the indoor unit and cause dirty air to flow out into every air-conditioned room as a result.

Furthermore, the aircon system will have to work harder if the filter is blocked and airflow is reduced. Sadly, this can cause unnecessary air conditioner damage.

At this point, you may think that the cleaning process is kind of complicated.  However, it is simpler than you may think.

The first step is to make sure the filters need to be cleaned. To do this, you can hold a filter up to the light and see if you can see light through it. If you cannot see light or it is very dull, you will need to clean it or change it depending on the filters you have (washable or disposable).

What are the steps to follow?

  1. The first thing you should do is to make sure the AC system is off.
  2. After that, you should undo the return air grille hinged frame fixing, that is usually a thumb screw or sliding clip.
  3. Then, you should slide the filter out carefully and vacuum off any dust, lint, grime or any other matter on the filter, outside if possible.
  4. Once you have vacuumed everything, wash the whole filter with mild detergent and warm water, soak it in a bath or a large body of water and move the filter around to dislodge anything that could be stuck in the filter. Also, you can rinse it off with a hose outside the house or do it in the shower with low-moderate pressure water.
  5. Give the filter a final rinse. You may choose to sanitize the filter with vinegar, diluted with water (50/50).
  6. After that, gently tap the filter to remove excess water and allow it to dry in a warm area. It is better to leave them outside but not under direct sun. Also, keep the filters out of windy areas and away from dogs and other animals that can damage them.
  7. Remember to check your filter condition regularly. If it is coming away from the frame, has any tears or if the material is getting thin then it is time to change the filter. You can get a made-to-measure replacement filter on request with a good air conditioning service and repairs technician if you want to.
  8. Once your filter is dry you may choose to apply an antibacterial spray to help prevent bacteria and mould build up.
  9. Slide the filter back into the hinged grille inside, swing the grille back into the ceiling recess and secure it. Remember that the filter is directional, which means that it has a right and wrong way to slide it back. Just makes sure you put it in the right way.
  10. Finally, turn the aircon on and test run the system. If it makes any whistling noise, adjust the filter so the sound disappears.  If you hear any other weird noises, turn the aircon system off and contact an expert to see where the problem may be.

Replacing air filters

How to clean wall split system filters?

Servicing filters for wall split units, box air conditioners and cassette systems is also necessary to increase the lifespan of these systems and maintain a healthy indoor environment.

What are the steps to follow?

  1. First, turn off the aircon system and open the front cover of the indoor unit.
  2. Gently slide the filters out and look for specific instructions or refer to manufacturing specifications.
  3. Vacuum off all the matter on the filters like dirt, lint, grime, dust and mould. This is best performed outside.
  4. Once you vacuum everything, wash the filters with mild detergent and warm water and soak them in water to dislodge anything that could be stuck within them. Another alternative is to rinse them with a hose or in the shower.
  5. After that, rinse the filters one more time. You can sanitize them with vinegar diluted in water as a 50/50 mix.
  6. Then, tap the filters to remove the excess water and put them to dry in a place with warm, fresh air, away from pets and wind.
  7. Remember to check filter condition. If they start coming away from the framing, have any tears, or the filter media is getting thin, then is may be time to change them. You can contact an air conditioning service and repairs company to help you replace filters.
  8. Once the filters are dry you may spray them with an antibacterial spray to prevent mould and bacteria growth.
  9. Finally, slide the filters back into the indoor air conditioner unit and turn the power back on as well as to the aircon system.
  10. Test run the system. If you hear any whistling, adjust the filters to solve the problem. However, if the noise is abnormal then the best recommendation is to call an expert to see what the issue may be.

Cleaning air conditioning filter

What to consider before performing the cleaning?

Aircon filters are delicate so you should not use abrasive cleaners. Otherwise, you may damage the nylon or similar material your air filters are made of. If this occurs, your filters will be useless so please be gentle when cleaning them.

It is also not recommended to use brushes with hard bristles because this can cause holes, reducing the filtering capacity. Also be wary of pets and other animals around that may like to nibble (or completely chew) the filter when left out to dry.

Also allow plenty of time for the filters to dry, especially if you are in a cooler climate or alternatively very humid environment. Both environments cause complete drying to take longer than it would if you were in a hot, dry climate.

How often the filters should be cleaned?

It really all depends.  It depends on the environment where you live or work; if there is a lot of pollution, if anyone smokes regularly, if there are animals present, or if the place in general has a lot of dust. If yes to one or more of these, you should clean the filters more often compared to places that don’t have as many pollutants.

It also depends on usage of the air conditioning system; if the air conditioner is used most days, if the AC is run at low temperatures, or if the aircon unit is closed up immediate after heavy use, as well as the settings and fan speeds used. If yes to any of these, more frequent aircon filter cleaning will be required.

In general, the most common recommendation it to clean your home air conditioner filters every 3-6 months, i.e. with every change of season, or every time you change the function of the aircon if it is a reverse cycle air conditioning system.

However, it should be recommended to at least check your aircon filters monthly, especially in a commercial setting. Depending on the environment and usage, cleaning may be required at the same time or can occur with the change of season or function as mentioned.

Why the aircon filters would smell bad?

Filters don’t generally smell bad; they just perform their function of filtering air and trapping dust particles in the mesh from which they are made. By doing this, filters prevent these particles from reaching the interior of the unit and therefore help prevent the aircon from getting dirty inside.

Aircon filters may start to smell bad when they become clogged and saturated. At this stage, they can no longer perform their function properly. This causes dirt to gradually pass into the indoor unit.

Dirt and matter can build up within an AC unit as well as lead to the growth of microorganisms and mould. Any of these can cause an unpleasant odour. Therefore, it is usually the interior of the air conditioner unit that smells, rather than the air filters themselves.

Dirt and matter, when combined with moisture produced by an indoor unit operating in cooling mode, can cause mould, bacteria and fungi to proliferate and may be harmful for your health. For this reason, you have to carry out regular maintenance and keep your aircon filters clean.

Air Conditioning Odor

If your air conditioner is not cooling properly after cleaning the filters you may need to consider two common situations:

  • If the equipment is old or if the installation was not done correctly, component/s may be faulty or gas may have leaked. If so, you will need to call an air conditioning contractor to investigate and solve this problem as soon as possible.
  • If you live in a place with excessive pollutants and dust, this may result in the accumulation of dirt within the indoor unit. It would also be best to have this attended to by an AC expert as soon as possible.
