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.

It can be a difficult task to find the perfect air conditioner for your business. With so many options in the market, how to choose? You have to think about your commercial premises; is it just a small office? Then you may choose to go with ductless air conditioning. But if you need to cool down several offices, then ducted air conditioning may be the best option for you.

Remember that choosing air conditioning that does not suit your purposes can result in issues like excessive cost, failing to create a comfortable environment, and poor energy efficiency.

Take into consideration that employees that are comfortable while working are more productive, happier, and less stressed. Suitable ducted air conditioning can provide outstanding return on investment.

What is ducted air conditioning?

Ducted air conditioners consist of the outdoor device, which is normally installed outside on the ground, wall bracket, or roof. It is connected to an indoor unit of rectangular shape that goes above the ceiling of a room/indoor area. The two units are connected by refrigerant pipework.

In this way, it will go unnoticed and help ensure the pleasant aesthetics of the office or work space. From here, running off the indoor unit, there will be a series of ducts that are located in the ceiling space running to all rooms/zones.

In each room or zoned area, there will be supply air grille/s, through which air is expelled. There will also be return air grille/s located elsewhere via which air returns to the indoor unit. This ensures proper air circulation.

Many key design elements must be taken into account. For example, all ducted air conditioning equipment requires a control device that often also acts as a thermostat. This is usually placed in the main room or in the hallway, where you can control and operate the ducted aircon.

So, what are the advantages of ducted air conditioning?

There are many factors you should consider before installing ducted air conditioning.

More productivity

Regardless of the weather condition outside the workplace, it will maintain an optimum temperature throughout the indoor workplace. This will lead to people feeling comfortable, thus they will be more productive.

On the other hand, if they feel that their office is really hot then workers will not be focused. This is the last thing you want. Remember that if you are serious about creating a perfect work environment then you need to have aircon to help staff be healthy and productive.

Energy-efficient and thermal insulation

Ducted air conditioning has great thermal insulation and this feature significantly limits the energy consumption of the entire ventilation system. Furthermore, the aluminium coatings present on both sides of the panel ensure excellent waterproofing and vapour blocking performance.

Also, it is proven that ducted air conditioners are capable of reducing your energy consumption. Furthermore, the performance can be higher, even higher than conventional aircon units. Additionally, ducted systems are often the most aesthetically pleasing option you can find in the aircon market.

Uniform temperature

Another one of the great advantages of ducted air conditioning is the uniform temperature. With correct ductwork designed and installed, you can achieve more uniform air conditioning and climate control across the different areas of your office or business space.

The reason for this is that a centralized system allows you to distribute better air through different outlets. In this way, it optimizes its performance compared to a single air outlet where you need higher power or lower temperature to cool down the areas that are far away from the machine.

Capability of zoning

Zoning is amazing if you are going to climatize different offices and areas because not everyone likes the same temperature. Some may feel it is too cold while others may feel it is not cold enough. The temperature battles in offices around the country can be endless. However, zoning can help this.

Not all centralized air ducted systems allow zoning but they are the main aircon type that has this feature and it is an important advantage. You will be able to manage every room independently through the controller. Also, you will be able to close the circulation of hot or cold air by zone if you want to. The degree of control depends on the zoning system in place.

This is a great way of making sure that the power and consequent expenses are focused only on those rooms where people are using the aircon. This lets you save money in the long run as well as preserve the ducted air conditioning equipment.

Secure

The air conditioning ductwork is relatively light and it requires few anchor points to install. Thus, it is much safer in case anything falls due to an accident or even earthquake.

Another important advantage in safety terms is the excellent fire resistance. In the commercial setting, R1.5 (fire rating) or higher is often recommended and used, compared to R1.0 in homes.

Useful for summer and winter

Unlike other systems, ducted air conditioners can help you in winter and summer. Reverse cycle air conditioning is standard for ducted aircons. This allows achievement of a perfect temperature with only one air conditioning unit/device.

This is why ducted air conditioning offers you a complete solution for its whole lifespan. This  can be up to 20 years if you give it proper AC maintenance.

What may be some disadvantages?

The ducted air conditioner has a lot of advantages, but it also can have some disadvantages depending on your budget, needs, and location.

If your office does not have the pre-installation of ductwork done, then you will have to include installation of the ducts in the air conditioning installation. This may increase the cost of the complete aircon system and installation.

It is a possibility that your office does not allow you to run refrigerant pipes because of the building structure. For this reason, you may have to reject this air conditioning system type.

Also, investment in ducted air conditioning systems is often high depending on the spaces to be air-conditioned.  However, as we mentioned before, you can save money in the long run because it’s likely that you will be choosing an energy-efficient device and this will reflect in the quarterly energy bill.

Finally, ducted air conditioners have a particularity because in very cold regions it is better not to install them. Otherwise, the air conditioning equipment can suffer and have poor performance when the temperature outside exceeds -5ºC.

Children, especially newborns, are very sensitive to sudden changes in temperature. This is because temperature alters them easily. For example, at night if they are feeling too cold or too warm they can wake up and feel distressed.

Remember that air conditioning can be very beneficial for your family, especially for your children, but only if you know how to manage it properly. Air conditioning is not harmful to the health of your children at all, but you have to use it with a series of precautions and not use it excessively.

If you make responsible use of the air conditioning, you can help your newborn achieve a better sleep. You can also keep him or her away from some diseases related to extreme heat.

Temperature and humidity

With the presence of very young children, it is necessary to control the humidity and temperature of the room where air conditioning is in operation. In other words, indoor climate control.

Remember that air conditioning is an excellent ally to be able to cope with the extreme temperatures of summer days and nights. In this way your child will be much more comfortable, thus enjoying a fresh and pleasant atmosphere and avoiding any bad experience related to extreme temperatures.

You just have to ensure that temperature and humidity are suitable as an atmosphere too cold and dry can affect the baby’s respiratory tract. A temperature of 25 degrees will be ideal so the heat does not negatively affect adults and there is limited risk of over-cooling in young children.

Keep in mind that as you are looking not to have a dry atmosphere, it is also necessary to avoid excess moisture. This is because moisture favours the growth of mould and fungi, increasing certain health risks.

The moisture at home should oscillate between 30 and 50%. Also, you must try to “air out” all the rooms regularly. To control these parameters, it is useful to have a thermometer and even a hygrometer at home.

Finally, it is preferable to have air conditioning throughout the house and not only in certain rooms. In this way, you and your children will avoid abrupt temperature changes, which can have a negative impact, especially on newborns. These changes can weaken the immune system of minors, which increases the risk of diseases.

Tips for using air conditioning when you are at home

When you have a newborn you must be careful with the use of air conditioning. If you are going to use it, keep these tips in mind:

  1. To avoid sudden temperature changes. The difference between the inside of the house or the car and the outside should not be very large. Ideally it should not exceed 10 degrees of difference.
  2. Do not place the baby near the air conditioning. If the cold air gets on the baby directly, this can make him/her ill. All the rooms should have the same temperature if the air conditioning is functioning properly, then there is no need to place the baby that closes to the air conditioning.
  3. Remember that excessive air conditioning of the indoors can cause stinging or eye itching and drying or irritation of the respiratory system. You must get some degree of humidity at home.

For this reason, you may choose to use a humidifier. That is, a container with water in the bedroom or use an air conditioning system that also regulates the humidity at home.

  1. If you use a humidifier, keep in mind that you should never surpass 50% humidity. Otherwise, this may encourage fungi to grow in the environment and induce baby allergies.
  2. Do not turn on the air conditioner and the humidifier constantly. It is important to leave time for good outdoor daily ventilation.
  3. Do proper cleaning and maintenance on your air conditioner, because pollen, dust, mites, and fungi accumulate inside the filters.

Tips for using air conditioning when you are not home

When you and your family leave the house there are some things you should do.

  1. If you have to go outside when it is very hot, turn off the air conditioner for a while before your children get in because they are now used to the outside temperature. As we have pointed before, you have to avoid sudden temperature changes.
  2. When you walk out with your new-born, you have to always put them in warm clothes. This is because you may go to a store, restaurant, or shopping centre where air conditioning has a lot of power and the temperature is typically very low.
  3. As for the air conditioning in the car, before getting in you have to open the windows so that the hot air goes out. Also, when using the car, you must be very careful with new-borns. You have to mitigate the heat with frequent stops and low air conditioning.

Benefits of using air conditioning for a new-born

Unstable temperatures at home and poor air quality can cause children to suffer from several health problems like skin irritations or rash, bleeding nose, scratchy throats, congestions, infections, itchy eyes and extreme fatigue, just to name a few.

Also, a new-born 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. Keep in mind that the cooled air reduces humidity levels and mould in your home.

Air conditioning is designed to purify the air, removing allergens and pollutants. However, you can further improve your indoor environment with something like the Daikin air purifier.

Remember that a home air conditioner is greatly beneficial at any time of the year if it is used correctly. Getting adequate air conditioning greatly improves quality of life for people living there. This is especially true with energy-efficient air conditioners or more digital devices where you can easily schedule it to obtain a friendly environmental outcome.

Keep in mind that, especially in summer, you must use common sense to protect children from heat since they are not only more susceptibility to changes in temperature but also depend on adults to control everything related to their environment. This is especially true for newborns, who depend solely on adults for their health and survival.

If we tell you that you can save money and take care of the environment while having an air conditioner at home, would you believe us? Well, the truth is that it is possible, if you choose an energy-efficient air conditioner.

You can find energy-efficient appliances including air conditioners in almost all their forms. It may be a higher investment at the beginning compared to a regular air conditioner, however the long-term savings can make up for it.

What is energy efficiency?

Energy efficiency refers to the optimization of resources to achieve a goal. This means using less energy than normal for an appliance to work but achieving the same results. Thus, energy efficiency includes all those actions that aim to save energy without representing an impact on your qualify of life.

Using energy efficiently also means not using it in unnecessary ways and doing what you require with the minimum possible consumption. To achieve this, it is essential to explore new technologies and systems that save energy to achieve a sustainable life.

The efficient use of energy contributes to protecting natural resources and reducing environmental impact. For this reason, it is not only necessary to have efficient technologies, but also responsible for consumers like you.

How to measure energy efficiency?

To make sure that you are truly increasing energy efficiency throughout your home, optimizing the performance of your appliances, and achieving your objectives it is essential to measure energy consumption.

The easiest way to measure your energy savings is through the annual cost of electricity. If your power bill is small/smaller, it means that the energy efficiency in your home is high.

The importance of energy-efficiency

The energy efficiency of the air conditioning is measured based on the amount of energy generated for each kW of energy consumption. The higher the energy generated for each kW spent, the more efficient your system will be.

Furthermore, all appliances have a label that explains their energy efficiency. This efficiency is measured with different letters, from “A” to “G”, with “A” being the most efficient and “F” and “G” the least efficient.

Remember that energy efficiency is one of the main saving factors that must be taken into consideration if you want to ensure optimal use of your air conditioning.

How to choose an energy-efficient air conditioner?

To choose an energy-efficient air conditioner you need to think about your own needs but also identify the models that consume less energy.

Energy

For you to make sure to invest in an air conditioner that doesn’t consume too much energy you need to look at its label, which can range from A +++ to B depending on kW rating.

You should have a higher budget to install your air conditioner because cheaper alternatives often offer low performance and high electricity consumption.

The EER rate

To measure the true efficiency of an air conditioner, it is essential to compare the EER rate or Energy Efficiency Rating of each model. This refers to the amount of electricity needed to obtain a defined cooling capacity.

To sum it up, the more energy it takes to reach the desired objective, the more power the device uses.

Energy consumption

Energy consumption is an excellent indicator to anticipate the impact of air conditioning on the annual electricity bill. It is measured in kWh and you can simply compare the information for each model to make an informed decision.

Sound of the air conditioning system

The sound of an air conditioner varies between 45 and 60 dB. What you should do to not have any problems with your air conditioner is looking for the ones with the lower levels.

The good news is that energy-efficient air conditioners possess high-level technology with hardly any sound.

How to optimize your energy-efficient air conditioner

Look at the label

An energy-efficient air conditioner can save up to 60% more than a conventional one. For this reason, as we stated before, there are appliances that are cheaper but they are not energy-savers but in the long run. You will pay for them eventually!

Always keep your appliance in good condition

Performing regular maintenance on your air conditioner is key to extending its lifespan. Also, avoiding dirty aircon filters is essential for the proper functioning of your air conditioner. It also keeps away all the mould and bacteria that may affect your health and the health of your family.

Having habits to minimize the heat in your home

The best tip that we can give you to minimize the heat in your house is to ventilate your home at night, so this will cool down the environment in the morning. For the rest of the day, it is better to keep the windows closed so this will avoid increasing the temperature of your home.

Keep in mind that if you are going to leave the house, you should turn off your air conditioner and turn it on when you come back. In this way you will be saving energy and money.

Monitor and regulate the temperature

The main reason to buy an air conditioner is to be comfortable at home. However, it is a great idea to make your air conditioner work as efficiently as possible. For this reason, we recommend you set your aircon at 22-24ºC. For each degree you adjust beyond that, you can increase the cost of your bill up to 10%.

Help yourself with other elements

When the heat is not suffocating, having ceiling or portable fans installed can help you save energy and money as you will not be using the air conditioner as frequently.

Even when you do have the aircon on, fans can further enhance the cooling effect and reduce demand on the air conditioner. This leads to further energy savings and comfort.

Get advice from a specialists

It is not the same to cool down a small place vs a large place or design an air conditioner system for a room vs a whole house with several rooms. There are many other factors that effects which size of air conditioner you need to have greater energy-efficiency. For this reason, it is better to get advice from a specialist.

Remember that being more efficient does not mean giving up a degree of well-being and quality of life. It is simply a matter of adopting a series of responsible habits, measures, and investments at a technological and decision-making level.

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.

Ill woman

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.

When you invest in a new air conditioner, it’s common to be focused on the cost of the system upfront, the energy efficiency of the aircon, and when can it be installed.  Once these initial concerns are resolved, it’s time to start thinking about the lifespan of your air conditioning system.

There are many different factors that impact how long an air conditioner unit will last.  These includes but are not limited to installation quality, how your use the system, strategies in place to assist the aircon, type of maintenance carried out, the nature of repairs, and paperwork in place from start to finish.

Fortunately, there are many things you can do to ensure your new air conditioning system reaches its full potential.  For this reason, the article will go through 7 key areas worth focusing on.  For each area, we will narrow-down information into 4 main points that can make or break your aircon’s expected lifespan.

Installation

Before you even install your air conditioner, there are things that can be done to ensure the air conditioning equipment reaches its full potential and lifespan.

Two workers in uniform installing air conditioning

Design/Size

Design

Before installing any air conditioner units, you want to ensure they form part of the most suitable, well designed AC system for any given application.  For a floor, ceiling or wall mounted split system, position and associated components installed are vital.  For a ducted system, layout and quality materials can seriously impact the longevity of your air conditioning system.

For a ducted AC system, with a network of ductwork in the ceiling space, it’s important that the system is designed and installed by an experienced ducted aircon installer.  Many factors impact the ongoing efficiency of the system, including zoning type and layout, ductwork size and insulation rating, supply/return air outlet size and number, and wall controller/thermostat/sensor location.

Poor design, inferior materials, and poor workmanship will cause the system to struggle and wear out faster as a result.  It will also cause endless issues and excessive power usage along the way.  This is true for ALL air conditioning unit types.

As a result of sub-standard design, you will need replace the air conditioning system sooner than you would with a higher quality and suitably designed system.  For the sake of a few dollars saved upfront, you can easily end up paying far more in the long run.

Size

Before installing an air conditioner, it’s important to ensure that it is a suitable size for the area it will serve.  This refers to the capacity, typically measured in kilowatts (kW).  Just like Goldilocks and her run in with the Three Bears, an aircon can be too big, too small, or just right.

If you put in an air conditioner that is too big, it will cycle on and off more frequently as it tends to overshoot the desired temperature, detect this, stop, wait for temperature to go the other way, and then blast out hot/cold air again.  This constant on/off and short cycling damages the internals of the AC units as they are designed for run for longer periods of time and complete certain cycles.  This means the internal components will fail earlier than designed.

If you put in an air conditioner that is too small, it will tend to have to run for longer and complete more cycles before it turns off.  It may not even reach the desired set point, meaning it continues to run non-stop!  This will cause the internal components to wear out much sooner as they never get a break, except when the system is not in use.  This is why server room aircons (running 24/7) only come with a 1-year manufacturer’s warranty, rather than a standard 5-year warranty.

If you are not sure what design and kW rating air conditioner you need, it’s best to chat to an experience AC installer about what sized air conditioning system would be best for a certain space.  There are many factors to consider, such as the size of the area (m2), heat load/activities conducted indoors, insulation/materials used in the building, and building/window/door orientation.

Unit Location

Indoor Unit

Before getting air conditioning units installed, you want to make sure they are going in the right location.  Otherwise, the system can be compromised and lifespan reduced as a result.

For a wall split indoor unit, it’s best for the unit to be installed:

  1. Back-to-back with the outdoor unit. Efficiency of the system decreases as pipework length increases, so you want to prevent excessive pipe run.  Decreased efficiency means increased strain on the whole air conditioning system.
  2. Centrally near the middle of the room without obstruction. Supporting even airflow and temperature dispersions with a central, obstacle free location reduces workload.  This preserves the AC system as whole and helps extend its feasible running time.
  3. Up high up on the wall close to the ceiling (~2.4-3.0m off the ground). Obviously if there are cathedral ceilings or similar, then the indoor unit should be as high as reasonably practical.  This recommendation is designed to complement the natural phenomenon of hot air rising and minimise demand on the aircon.  It also helps support optimal performance and allow reasonable access for routine maintenance.

There are also important factors to consider when installing a ducted air conditioning system.  Ducted AC units need to be installed in a position that supports ongoing efficiency, maintenance, and repairs.

For a ducted indoor unit, it’s best for the unit to be installed:

  1. Close to the manhole. This allows ease of access to the unit to support routine maintenance.
  2. Suitable distance away from the ceiling and/or beams in the roof. This also allows suitable access for a professional service, chemical coil clean, and/or repairs.
  3. Suitable proximity to supply and return air ductwork. This ensures efficiency is not lost through excessive flexible duct runs.

The ducted return air grille/filter that allows air back into the indoor unit is also important to consider.  This critical air re-entry point must be visible and accessible in a well-ventilated part of the home or office.  Otherwise, it can easily get blocked, increase pressure on the system, and lead to AC equipment failure.

Outdoor Unit

Just like with the indoor unit, before getting your new air conditioner installed, you want to make sure the outdoor unit is going in the best location.  Failure to do so can result in reduced AC lifespan in many ways.

The outdoor unit (i.e. condenser) is the powerhouse of an air conditioning system.  The harder it has to work, the less efficient the whole system is.  Running the air conditioner in a lower efficiency state causes the system to wear out faster.

To prevent this issue, it is recommended to install the outdoor unit a well-ventilated, cool, dark/shaded place.  This is because heat and sunlight can increase the unit workload as well as cause certain components to wear out faster.  Condenser pipework insulation is just one example of a UV-sensitive aircon component.

It’s also recommended to install the unit down on the ground, or in an easily accessible location, as opposed to a roof top or similar.  Not only does this help reduce sun and heat exposure, but it also supports routine inspection and servicing as the unit is then in a suitably accessible location.

Wherever the outdoor unit is installed, it’s important for it be level, clear from obstruction, and suitably secured.  If not level, the unit cannot work property and components wear out faster.  If not clear, airflow is reduced, causing components to overheat and fail prematurely.  If not secure, opportunist vandals or clumsy passers-by can damage the unit with a range of life-altering consequences.

Pipework

To ensure your air conditioner reaches its full potential, it’s important to ensure the correct refrigeration pipework is used in conjunction with the unit install.  Specifically designed pipework improves AC operating efficiency and prevents a range of issues.

Pipework used should be purposed for aircon installs; pre-insulated, UV-rated, annealed copper pair coil.  It should also be of the correct size for any given air conditioner and suitable length as per AC manufacturer specifications.

  1. The insulation component reduces sweating of pipes.  This is important as water is never a good thing to have around an electrical device such as an air conditioner unit.
  2. UV-Rated. The UV protection component reduces degradation in the face of UV light.  Unrated/inferior pipe insulation can breakdown and reduce system efficiency in as little as a few years.
  3. Correct Size. Undersized pipe will prevent the system from operating at is maximum potential, meaning the system can struggle to adequately heat or cool a given indoor area.  Oversized pipe can cause serious compressor damage and premature equipment failure.
  4. Correct Length. AC system efficiency increases as pipework length decreases, to a certain point.  While it is recommended to keep pipework length as short as possible, there will still be a minimum length required depending on the unit size and manufacturer instructions.  Incorrect length can also cause noise and/or vibration issues, which negatively affects aircon lifespan.

Drainage

Drainage may not immediately come to mind when considering how to extend the life of your air conditioner units.  However, it can certainly play a significant part in preventing unnecessary and life-reducing damage.

AC units produce condensate (i.e. water) during normal operation.  That water is collected in internal drip trays and drained away as required.  If your aircon is leaking water where it shouldn’t, it’s a big problem.

Excess water can promote micro-organism, fungi, and bacterial growth within an aircon unit.  This can cause mould and matter to build up on the coil, fan scroll, filters, and other AC components.  This reduces airflow and increases workload of an air conditioning system, impacting its expected lifespan if not resolved in a timely manner.

Failure to install a drip or safety tray, or suitable drainage, means that water may not be collected at the indoor unit and/or suitably drained away.  This can result in water overflowing onto AC electrical components.  As we all know, water and electrical do not mix.  Modern-day aircons are heavily electrically based, so water can cause significant damage to components such as printed circuit boards, capacitors, controls, etc.

Water can also damage structural or supportive components of the air conditioning system.  For example, water can compromise the structural integrity of the wall, floor, or ceiling below the unit.  As a result, the aircon may become unlevel or fall completely.  Unlevel units wear out faster or may fail to operate correctly at all.  Meanwhile, a complete fall could see the end of that particular AC unit.

Usage

Once your air conditioner is installed, there are many ways you can preserve the equipment and extend the lifespan of the system as a whole.

Controller/Temperature Sensors

Heat Load

Usage of an AC controller and temperature sensors can make or break the lifespan of any air conditioning system.  Incorrect usage can prevent correct system operation, increase workload, and waste power.  On the other hand, correct usage can extend lifespan and save you significant money in the process.

The air conditioner controller can also double as a temperature-sensing point.  This is often the case for entry-level ducted systems.  An increase in heat load near a temperature sensing component of the AC system will result in excessive cooling and subsequent workload for the AC system.

Once correctly installed, the area around sensors and temperature-sensing wall controllers must be considered.  It is recommended to avoid placing anything producing excessive heat in close proximity.  This includes common home devices such as washers, computers, TV screens, phone chargers, etc.  Direct sunlight must also be monitored and managed.

Set Point

Once the area around the temperature-sensing point is managed, the next consideration should be the temperature set point.  Minimising excessive usage of the air conditioner helps with preservation and system longevity.

Standard home air conditioners are designed to run at full capacity or idle.  They continue to work at full capacity until they detect that a given set point is reached.  At this point, they can then ramp down and reduce demand on the air conditioning system as a whole.

It is recommended to set the air conditioner to a temperature as close to the outdoor temperature as possible.  Some change is obviously expected, otherwise why would you use the AC, but every degree counts.  Not only is the system running life extended as a result, but aircon running costs are also reduced by 10% for every degree the set point is set closer to the ambient temperature.

Settings

Mode

The modes selected when running an air conditioner can reduce or enhance the expected lifespan of that system.  It is one of simplest ways to extend the life of your air conditioning units.

It is recommended to avoid Auto mode most if not all of the time.  Auto mode causes the aircon to automatically switch between Cool and Heat modes with the aim of steadily maintain a given set point.  This is an inefficient use of the AC system which unnecessary causes it to wear out faster.  Heat mode or Cool mode is recommended to be used instead.

There are other modes that can help enhance your air conditioner and its lifespan.  Dry mode increases the amount of air passing through the indoor unit, designed to remove moisture from the air rather than cooling it.  This this a more efficient mode that reduces power usage and demand on the system.

Fan mode is another more efficient mode available to preserve your air conditioner.  It allows air movement without inherent temperature adjustment or dehumidification.  It is one of the best modes available for extending the life of your air conditioner units.

Many aircons also have a Sleep mode or Night mode which can help extend the life of both you and your air conditioning system.  Sleep/Night mode increases temperature gradually by a few degrees, 0.5 – 1 degree at a time, to reduce demand on the aircon units without impacting your sleep.

Fan speed

Fan speed has a surprising impact on air conditioner energy efficiency and therefore system lifespan.  Fan speed refers to the speed of air travelling through the indoor unit, i.e. over the internal heat exchanger coil and subsequently blown out into the room/s.

Using high fan speed is recommended to rapidly and efficiency cool down a given indoor area.  This is the recommended way to bring up or down the temperature indoors to support your air conditioner and prevent unnecessary strain.  Once the desired comfort level is reached, fan speed can then be adjusted down to maintain the temperature.

Overnight, low fan speed it recommended as temperature maintenance is often the goal and the outdoor temperature often decreases significantly.  If it is a particularly humid day, and/or moisture removal is the primary goal, then low fan speed is also recommended for use.  This allows more time for the indoor unit to remove moisture from the air before it leaves the unit and enters the indoor environment.

Timers/Reminders

Timers and reminders are handy to have in an air conditioner unit as they help you manage its usage and extend its life.  Not all aircons come with timers, so it’s worth ensuring your chosen system has one before making the final purchase and installation.

Timers can be basic, push-button operated, controllable over Wi-Fi, or even integrated into a complete home automation system (e.g. Google Nest).  The set and forget type timers may be the most beneficial, with life being so busy these days that few of us have time to stop and think about the aircon schedule on a daily basis.

Reminders also come in various forms, from basic “filter check/wash required” reminders through to “time for professional service” reminders.  These help to maintain the system overall and keep it in good working order.  The key is to actually action the task prompted; there is no point having a filter check/wash reminder come up if you just clear it without touching the filter!

Once installed and familiar with, the next step is to actually use them.  Timers can help manage demand on AC units at key times, such as when sleeping or out of the house.  As indoor climate requirements change, so should use of the air conditioner system to match.  By doing this, the system is preserved and life extended.

In a commercial setting, timers and reminders can contribute to significant life extension of the heating, ventilation, and air conditioning (HVAC) system.  Timers can be used to switch off units out of business hours, while reminders can prevent AC system neglect and assist with routine HVAC maintenance.  These benefits can significantly extend the life of any commercial system.

Additional Features

Timers and reminders aside, new air conditioning units come with a range additional features; some designed for convenience, some designed to enhance performance, and some designed to protect the aircon.  Better yet, some features can provide a combination of these benefits.

Control over Wi-Fi, typically via a smart phone App, is one of those features that has many benefits.  Convenience aside, being able to check and control an AC system remotely can support you in optimal running of the system.  For example, you can pre-cool the home gradually before you get home, rather than overloading the AC when you walk in the door on a hot day.  Similarly, you can check in on the teenage kids at home on school holidays and ensure they are not demanding excessive cooling or heating from the air conditioning system.

Many modern-day air conditioner units also have an Auto or Self Clean function inbuilt.  This function typically involves drying out the inside of an aircon unit, which preserves the internal components in many ways.  Moisture management reduces the growth of mould, mildew, fungi, and other unwanted microorganisms.  It also reduces rust and corrosion that would otherwise damage key components such as the heat exchange coil.

Assisting

Air conditioning units can be preserved by considering their place in the home as a whole, rather than in isolation.  There are many cost-effective methods of supporting the air conditioning system in place and extending its lifespan as a result.

Ceiling fan and air conditioning

Building

Air conditioning systems are best supported when used in a building environment that holds the hot or cold climate produced.  Insulation and window treatments are two key factors that have a significant impact on indoor temperature retention.

Insulation can be present in the ceiling, walls, floor, or combination of these locations within a building.  The impact of insulation is significant, with an insulated roof space saving you up to 50% on your home heating bill!  This saving shows just how much the demand on the AC system can be reduced.

Window treatments come in all shapes and forms, including blinds, curtains, shutters, tinting, or a combination of these.  Windows can allow significant heat to enter and leave an indoor space, and an imposed barrier can dramatically reduce any unwanted exchange. As a result, the air conditioning system doesn’t have to work as hard or for as long to achieve desired comfort level indoors.

Fans

Many properties have air conditioning installed without fans, thinking that fans are not required when aircon is in place.  However, this couldn’t be further from the truth.  The reality is that fans are needed, especially in hotter climates, to assist and help preserve air conditioner units.  They are in fact one of the cheapest ways to extend the life your aircon.  If not already installed, it would be well worth contacting a local electrician today.

Fans help to circulate air in a given space.  While they may not inherently change the temperature of the air, they help people in the space feel cooler due to the cooling effect produced.  As a result, demand on the AC is reduced as a higher set point can be comfortable with the presence of air movement.

Whirlybirds and other roof-mounted exhaust fans can also assist your air conditioner units in a different way.  These out-of-sight fans are designed to extract heat at the top of the house, lowering the temperature in the ceiling space.  As a result, the rooms below the ceiling space (i.e. indoor space) will automatically be cooler.  This will subsequently reduce demand on the air conditioner, as the rooms are already closer to the desired temperature.

Heat Load

Heat or cooling load refers to the amount of temperature adjustment required to maintain a given temperature set point.  The higher the heat load, the higher the demand on the air conditioner.  Therefore, it is recommended to manage heat load in order to extend the lifespan of air conditioning equipment.

Using heat-producing devices when an aircon is already under significant pressure should be avoided wherever possible.  For example, cooking sausages on the outdoor BBQ on a hot summer evening, rather than in the kitchen, helps to reduce the indoor heat load and subsequent demand on the AC system.

Running clothes and/or dish washers in the morning before the weather heats up is another way to assist your air conditioner.  Further methods include turning off lights when not needed, especially non-LED ones, and putting the extraction fan on when showering/bathing.

By reducing heat load indoors, especially when the AC is working at is max, you can reduce workload required from the device.  This prevents the air conditioner from being maxed out and protects the internal components.  As a result, you can expect to enjoy the aircon in your life for many more years.

Surrounding Area

The area around an air conditioner unit is just as important as use of the device itself.  A clear, well-ventilated space around all units is required to ensure an aircon reaches its expected age.  This can be difficult as standard house block sizes are decreasing and storage space is becoming limited.

The minimum clearance zone around an outdoor condensing unit is typically 300mm, with 1000mm required in front of the unit.  The area between the back of the unit and a wall may be slightly less but must still comply with manufacturer install recommendations.  Failure to do this causes reduced airflow and operating efficiency.  This can see an air con system over-worked, over-heated, and all over before its time.

Not only can items around the condenser impact the unit, but it can also invite unwanted flora and fauna damage.  While certain greenery can protect your aircon, like a shady tree over the unit, it can also harm it if neglected and allowed to grow into the unit itself.  Furthermore, animals feeding on or living in the garden can interact with the air con unit in several life-shortening or even life-ending ways (unfortunately for both parties).

DIY AC Servicing

One of the most effective ways of extending the life of your air conditioner units is servicing them.  Just like your car, your aircon requires a minimum amount of maintenance to get it through an expected lifespan.

Cleaning air conditioning filter

Frequency

DIY maintenance starts with regular filter checking, every few weeks, and washing when dirty.  It’s also recommended to check them after dirt or dust generating activities, such as spring cleaning, renovating or moving furniture.  More on filters later.

Aside from filter washing, there are many other simple aircon maintenance tasks that should be carried out routinely.  These tasks are designed to keep your air conditioning system working as designed, which helps it reach or even exceed predicted lifespan.

In a commercial setting, routine HVAC servicing is recommended monthly as Australian Standards.  Home air conditioners could also benefit from monthly maintenance, however every four to twelve months is typically sufficient.

The basic tests, checks, and cleaning recommended to maintain your own air conditioner has many benefits.  In relation to life extension, DIY aircon servicing allow for minor issues to be detected and resolved before they cause major damage.  It also supports optimal AC function and efficiency, which helps preserve major internal components.

Filter Maintenance

Filter maintenance is the number one service task you can do yourself to protect and preserve your air conditioning system.  However, there are more to filters than you may think.

Type

Firstly, it’s important to ensure the correct filter type is used with your AC system.  Types to consider, particularly for a commercial HVAC system, include manufacturer-specific, full/half ceiling tile panel, pleated, pocket, v-form, HEPA, or carbon.

The next consideration is the media type; washable or disposable.  Factors such as access, water availability (for washing), and finances (for purchasing disposable ones) impact which type is most suitable to support your particular aircon system.

Next point to consider is media/filter thickness.  There are clear Australian Standards for suitable air filter design and use in Australia depending on unit type and application.  To ensure correct AC operation, the filters should let air through to the indoor unit but be thick enough to suitably filter the air.

Clean/Replace

Filter cleaning is one of the most effective ways to maintain your air conditioner and ensure a long and healthy life.   Dirty filters increase air conditioner workload by 15% as evidenced by power draw.

Dirty or damaged filters prevent dirt, dust, dander, and other types of matter from being filtered property.  These can reach and/or build up in the indoor unit, which impacts aircons in many ways.  It promotes the build-up of dust, mould, mildew, fungi, and other microorganisms that reduces heat exchange on the evaporator coil, increasing strain on the system.  It also spreads dirty air, which is not only bad for your health but also for the health of your aircon system.

While it is a far less common issue, it is worth noting that filters can actually be washed too much.  This is more commonly seen with commercial HVAC systems, where business owners may insist on monthly filter washing even when a system is hardly used.  The media wears out over time, especially with washing.  This may not be a life-impacting issue for your aircon system UNLESS you fail to replace the filter when required, which may be sooner than expected with over-washing.

When a filter has worn out, it’s important to replace it or at least the filter media.  You can tell that a filter needs to be replaced when it is wearing thin in parts and/or light is more visible when you hold it up to a light source.  Failure to replace a relatively inexpensive part can see major aircon repair expense due to component damage, failure, or complete AC system failure.  An experienced HVAC technician can help you decide when filter replacement is due, as it can be a fine line between premature and overdue replacement.

Water/Cleaning

We all know that water and electricity do not mix.  The same can be said of electrically based devices such as air conditioners.  Water damage to AC components such as capacitors, PC boards, and motors can have life-shortening or even life-ending consequences for the system.  It can also cause corrosion and rust.

It’s not as simple as you may think, as some water is unavoidable when it comes to aircons.  Condensation (water) is produced as a normal part of refrigeration cycle.  It’s just a matter of managing the presence and use of water in order to maintain the air conditioning system.

As with filters, certain components of your AC system require inspection and cleaning when dirty.  For an indoor unit this includes the drain pipe/tray, fascia/covers, air inlets/outlets, fan barrel/scroll, and evaporator coil.  For an outdoor unit this can also include the drain, covers, coil, and area immediately around the unit.

Failure to keep these components clean can result in reduced heat transfer, reduce airflow, and reduce efficiency of air conditioner units, which shortens their life.  In the drains, all manner of blockages can occur, including algae, mould, sludge, insects, and even materials such as insulation.  To clean the various components, it’s recommended to use as little water as possible and the correct equipment for the job.

You also required complete knowledge of the electrical components (both directly and indirectly) involved in the area being cleaned to avoid harm to you and the air conditioner.  If you are not 100% sure, it may pay to call in a professional aircon service technician for such work, to avoid damage to the AC system you are looking to preserve, as well as yourself!  They also carry special chemicals and equipment designed to not only clean the system but slow future growth of mould and algae.

Visual Checking

Visual checking is one of the safest ways to maintain and extend the life of your air conditioner units.  It allows for issues to be detected while minimising the risk of physically harm.  Just take extra care if need to use a ladder or similar to access the aircon units.

When looking over the air conditioner, look at all visible parts of the system.  It is recommended to look for exposed electrical components, cracked insulation, water droplets or leaking in abnormal places, smoke or dust coming from the units, any signs of vibration or movement, and wearing/degradation in general.  You can also listen out for any abnormal noises, including banging, whistling, humming, squealing, gurgling, buzzing, rattling, etc.

It is recommended not to insert any foreign objects into the air conditioner while checking it.  This includes torches, sticks, screw drivers, brushes, and especially fingers.  Otherwise, damage can occur to AC components, the whole aircon system, the item you are inserting, yourself, and/or those around you.  Air conditioner damage can be as minor as a scratch or as major as complete system failure.

Professional HVAC Maintenance

While you can carry out a certain degree of maintenance yourself, there are some tasks that are best left to the experts.  It also pays to invest in a professional air conditioning service on a routine basis to help extend the life of your air conditioning system.

Technician checking air conditioner

Frequency

If DIY maintenance is routinely carried out on your air conditioner, professional maintenance is typically not required as frequently as if no home servicing has been conducted.  This home aircon servicing includes frequent filter maintenance, visual checking, basic cleaning, etc., as discussed.  However, it certainly doesn’t hurt to call in the experts to help maintain and extend the life of your aircon, and it is actually recommended to be done on a periodic basis.

Home air conditioners are recommended to receive professional maintenance every year at a minimum, and even every 4-6 months in certain situations.  Commercial air conditioners are recommended to receive monthly maintenance as per Australian Standards.   For anything less, it is recommended to arrange a formal inspection and proposal from a good commercial HVAC service company.

Even if the heating, ventilation, and air conditioning (HVAC) systems are seemly working OK, there can be hidden issues that impact unit operation and cause the equipment to wear out faster.  A professional can test technical components and resolve issues before they start to reduce air conditioner lifespan.  A primary example is testing of capacitor tolerance and replacing these minor parts before they damage the associated motor and system as a whole.

Service Level

Extending the life of your air conditioner not only involves maintenance, but also the correct type of servicing.  There are many different AC service types that can be booked, from minor checking through to major pull apart and deep chemical cleaning.  It’s recommended to arrange the highest level required to suitably maintain your aircon, otherwise you may just be wasting your time and money as well as reduce AC lifespan.

Ideally, the aircon service technician you book has the ability to upgrade the service level while onsite.  For example, start with a minor/standard AC service with the potential to add on indoor unit chemical cleaning if mould is found deep within the unit.  Similarly, if insulation on the outdoor pipework is cracked or UV affected, it is recommended to patch it at that time or follow up another time at a suitable add-on price.

While some professional attention is better than none, failure to fully maintain your system will severely shorten its expected lifespan.  If you are going to all the effort of arranging an air conditioning technician, it pays to get the complete service done at that time.  You can easily save the extra money spent with the extra life given to your air conditioning system.

Technician Type

There is a lot of choice when it comes to air conditioning service technicians.  Many air conditioning and electrical companies promote AC servicing, although their specialties and expertise can be worlds apart.

To get the most out of your professional AC service, it is recommended to book a technician with a valid ARCTICK licence.  This Refrigerant Handling Licence ensures that the tech can complete all tasks in a routine service, rather than just the electrical ones.  Handling AC gas/refrigerant is an offence unless you have this specific licence in Australia.

It is also recommended to book a technician with specialized air conditioning training and qualifications.  A heating, ventilation, and air conditioning (HVAC) contractor is technically a “Refrigeration Mechanic”.  This type of contractor is specialised in the refrigeration cycle, which is what all air conditioners are based on.  To help extend the life of your air conditioning units, it’s important to book the contractor that has been specially trained to care for them.

Recommendations

Once you have booked the correct technician at the recommended frequency to carry out the most suitable level of AC servicing, it’s then important to consider and action as many of their recommendations as possible.  Otherwise, you may not get the full life out of your air conditioner units.

Common recommendations worth actioning include set point for your system, filter cleaning frequency for your environment, chemical cleaning for your degree of mould/matter build up, clearance around the AC units for your unit location, and minor repairs for the state of your aircon.

Reputable air conditioning companies and technicians genuinely want to help you get the most out of your air conditioner.  Their reputation is also on the line if the units pack up and fail sooner than expected.  Therefore, a good tech will recommend ways to preserve the AC equipment.  However, if recommendations are ignored, they can not be held responsible for the shortened lifespan of your air conditioner units.

Repairs

Air conditioner repairs can vary from minor to major.  Some are critical to system operation, while some may not impact the lifespan of an air conditioning system.

Air Conditioner Parts

DIY vs Professional

Just like with air conditioning serving, there are tasks that you can do yourself and some that are best left to the experts.  You may be wondering what to do if air conditioner is broken.  Do you tackle it yourself or call in a professional?

First, the issue needs to be diagnosed correctly.  Just like Dr-google for diagnosing a medical condition, home air conditioner owners can feel like an air conditioning/refrigeration mechanics after 5 minutes of research online.  While you can be on the right track, error codes, noises and loss of function can be the tip of the iceberg in terms of air conditioning repairs required.

Misdiagnosis can waste time and cause further AC damage as you incorrectly think the system is still OK to use.  Furthermore, if you launch into repairs, the issue can actually be made worse.  This can cause great damage to an air con system.  Even worst, you can cause great damage to yourself and those around you.  It is recommended to call an expert to consult on your air conditioning issue/s and allow them to manage the repairs appropriately to maximise AC lifespan.

Timing

Sometimes we can’t help when our air conditioner needs fixing.  However, wherever possible, it is recommended to consider the timing of your air conditioner repairs.  This helps you to extend the life of your air conditioning units in many ways, but only if done correctly.

Firstly, some repairs cannot wait.  For example, gas leaks should be attended to ASAP to minimise the amount of gas lost from the air conditioning system.  However, if an air conditioner motor breaks down at the end of summer and the system isn’t needed until winter, it may pay to hold off repairs until the cooler months.

During the off-peak season, most air conditioning companies offer winter specials and more flexibility with when they can attend.  The AC repair tech is not as busy, so you may receive longer and more focused time onsite.  Aircon parts suppliers will also not be as busy, so they respond quicker with part details in order for quotes to be formed.  Parts can also be dispatched faster as they are not held up with high demand.

Overall, this results in a more pleasant, cost-effect air conditioning repair experience.  As a result, you are more likely to repair your air conditioner again in the future and work with the AC repair company to set up ongoing maintenance.  This helps you get the most out of your air conditioner and extend its life for years to come.

Noise

To extend the life of your AC system, it’s important to be aware of normal operational sounds.  By doing this, you can detect abnormal noises when they arise.  You can then do something about it to preserve your air conditioning system.

Indoor Unit

There are an array of noises possible from your indoor air conditioning unit.

  • Banging/Clanging – Possible loose/broken part such as fan barrel, louver, motor, or blade.
  • Squealing – Possible faulty fan motor bearings or housing. Noise may travel through ductwork.
  • Rattling/Chattering – Possible loose screws/bolts, faulty fan, or failing electrical contactor.
  • Clicking/Humming – Possible defective electrical component (wiring or thermostat) or loose part.
  • Buzzing – Possible range of issues, including dirty filters, debris in unit, rubbing/loose parts, motor/s out of balance, pipes rubbing between units, coil icing up, and/or refrigerant leak.
  • Screaming/Whistling – Possible refrigerant leak or component stuck.

These issues must be resolved by an expert in order to protect your air conditioning units and ensure a suitable lifespan.

Outdoor Unit

There are an array of noises possible from your outdoor air conditioning unit.

  • Banging/Clanging – Possible broken condenser fan blade, motor out of balance, or compressor issue.
  • Squealing – Possible failing condenser motor bearings or could be a normal start up sound.
  • Rattling/Chattering – Possible faulty fan or contactor, loose screws/bolts, or general wear and tear.
  • Clicking/Humming – Possible defective component (electrical or mechanical), loose component, or refrigerant piping vibration.
  • Buzzing – Possible range of issues, including dirty condenser coil, motor/blade out of balance, pipework rubbing, components icing up, and/or refrigerant leak.
  • Screaming/High-pitched Whistling – Possible jammed component or refrigerant leak.

All these issues should be assessed by an AC technician.  If the issue is not normal, it can reduce the expected lifespan of your air conditioner unit.

Refrigerant Gas

A gas leak can severely impact the health of your air conditioning system, the environment, and your family.  If suspected, it is recommended to book an aircon repairer ASAP to resolve the issue.  The air conditioner should not be used until issue resolved, otherwise major damage can occur to components such as the compressor.

You may first suspect a gas leak when the system fails to cool down the indoor space as well as normal.  If you lift the cover, you may also see ice forming on the evaporator coil.  Alternatively, water may be leaking from the indoor unit (i.e. melted ice).  Ice can also start to form on the outdoor coil and/or at the connection between pipework and unit.  This doesn’t mean that the leak is there, it just highlights that the system may be running short of refrigerant.

You may be able to hear hissing from small leaks, and gurgling from larger ones.  However, there may be no noise at all.  Another way you may detect an air conditioner being short of gas is your electricity usage.  If your power bill has increased significantly without another other explanation, it may be worth investigating your aircon.

A full gas leak search and repair is required to identify and fix all leaks.  The leak can be anywhere on the air conditioning system; indoor unit, outdoor unit, pipework, or connection between any of the components.  If the AC is less than 1 year old, it may be covered under installation warranty.  If the AC is less than 5 years old, it may be covered under manufacture warranty.  Either way, failure to resolve the issue will see a premature death to your air conditioning system.

Paperwork

Like all great things, your air conditioner will come with an array of paperwork.  This paperwork is important for many reasons and can be used to extend the life of your air conditioning units.

Licences

Firstly, before purchasing any new aircon, it is recommended to get a free quote for air conditioning supply and install in writing.  This sets out the inclusions and exclusions of your new air conditioner system as well as key details about the install company.

Next, it is recommended to check out the licences and qualifications of the proposing installation company.  For example, do they offer AC install, but fail to have a Queensland Building and Construction Commission (QBCC) air conditioning licence?  Checks like this can help ensure you are getting an air conditioner installed by an expert, which helps extend the life of the aircon.

Correct electrical licencing is also critical to ensure your air conditioner doesn’t wear out sooner than it should.  Not only is incorrect and unlicensed electrical work dangerous and can cause major property damage (including fires), it can also damage your air conditioner units.  Air conditioners come with electrical specifications such as power requirement, cable size, etc.  Failure to adhere to these specs will see a premature failure of the AC equipment.

Having a fully licenced company also ensures warranty for the new air conditioner units is maintained.  If not installed correctly, manufacturers will not honour their manufacturer warranty.  If the issue is major enough, you may be looking at throwing out your new aircon before it even reaches its expected half-life!

Receipts/Registrations

Once you have had your air conditioner installed, it is important to obtain a copy of the purchase and/or install receipt for your records.  This ensures you have important details on hand in situations that can assist with AC life extension.  However, any good air conditioning company should be able to resend a copy of your receipt at any time.

Air conditioner units typically come with a 5-year manufacture warranty, on the condition that the units are installed by a fully licenced air conditioning company/technician.  If any issues occur with the system within that 5-year period that is not caused by external causes, the system can typically be repaired at no cost to you.

However, if installation paperwork cannot be provided, manufacturers may not honour warranty work.  Effectively, warranty is void without valid install paperwork.  As a result, costs may be so significant that you find yourself throwing out the whole air conditioner and starting again with a new system.  This is particularly common with cheaper brands; the units are cheap to buy, but spare parts are terribly expensive.

Aside from installation paperwork, it also pays to register your air conditioner units and associated products whenever offered.  Sometime this supersedes the need for installation paperwork if a warranty repair is required, as the system details has already been registered with the manufacturer.  Furthermore, some AC components have an extended warranty.  For example, iZone zoning equipment comes with a 10-year parts warranty.  This can help you extend the life of your air conditioning system in the most cost-effective way.

User Manual

An air conditioner user manual is the ultimate guide for your air conditioning system.  It is sometimes called Owner Manual, Operations Guide, or Manufacturer Instructions.  Whatever it is called, it is full of useful information to help extend the life of your air conditioner units.

The manual contains operating instructions for the certain aircon model it relates to.  This helps ensure that the system is used correctly to prevent early equipment failure.  It also contains specific instructions for aircon maintenance and other ways to care for your units.  This further assists with system preservation and life extension.

When the air conditioner is installed, ask for a copy of the user manual.  If not received, just ask the installer to provide it or jump online to download a copy.  The next step is to actually read the content.  It’s probably no surprise that women tend to be far better at reading manuals than men.

Insurances

Once your air conditioner has be supplied and installed by a fully licenced installer, paperwork is received, any registrations completed, and user manual has been referred to, the next step is to review/update your home or business insurance policy.  While seemingly unrelated, this can actually end up being one of the most cost-effective ways of extending the life of your air conditioner units.

An air conditioner is a significant asset in any home or commercial building, so it should be covered by any appropriate insurance policy.  It’s worth checking what is covered and also what is exclude in relation to your air conditioning.  Common causes of damage relevant to your air conditioner includes motor burn out, fusion damage, storm events (including hail, water, or storm surge), electrical failure, fire, flood, animal, and accidental damage.

It’s worth weighting up the cost of some optional extras for your given situation.  For example, do you live in an area where flood could damage your AC?  Do you live in warmer climate where geckos (animals) wreak havoc with electrical equipment?  Is the outdoor AC unit in a carport or similar where it is at risk of accidental damage?

If the cost of repairs to your air conditioner is significant, you may think twice about proceeding with them.  For example, a compressor change in a ducted system can be half the cost of a new one.  You may consider investing the money into a whole new system instead.  However, if the repairs are related to an insured event, like a storm surge (lightening), then you are more likely to proceed with the life-extending repairs when all you have to pay is the excess.

In summary, there are many different ways to extend the life of your air conditioner units.  From the design and installation, to usage and assisting, to maintenance and supportive paperwork, there are many things you can do to support your air conditioning system.

The points outlined in this article are all cost-effective ways to support optimal AC operation and preserve your aircon system for many more years.  If you need help reviewing your air conditioning situation and extending the life of AC equipment, please don’t hesitate to contact us to discuss.

When the summer season begins, also begins the time of rest and enjoyment. However, on these dates, it may be difficult to sleep at night due to high temperatures, which can cause fatigue and prevent you from resting properly.

For this reason, some people prefer to sleep with the air conditioning on at night to alleviate these discomforts. This helps by keeping the indoor environment cool and ideal for optimal rest.

Still, not everyone knows all the benefits an air conditioner can provide when it comes to sleeping. This is even when many people are looking for the most optimal solution to fall asleep and achieve a complete night’s rest during the hot season.

That is why in the following article we will be talking about how sleeping with air conditioning can really help you, in lots of different ways, and can even be beneficial for your health.

Prevents sweating

Air conditioning will provide you with convenience and comfort of preventing bed sheets from sticking to your skin due to the effect of heat and sweating. What you have to do is choosing the most comfortable temperature for you, which will facilitate the transition to sleep.

Also, using the air conditioner can help you reduce humidity, avoid sweats throughout the night, and avoid waking up in the middle of your sleep. You need to keep in mind that when you go to sleep, the body temperature drops naturally to make it easier for your body to slow down. This is so you can recover from the activities carried out during the day.

Keeping the room cool, but not cold, can make it much easier for the body to relax, making it easier to fall asleep faster and sleep peacefully.

Regulates the temperature

By sleeping with air conditioning you will be able to regulate and maintain the temperature you want throughout your place. The greatest thing about air conditioning is that the system can be designed so that the air reaches every corner of the room.

Reduce the presence of insects

By having an air conditioning unit to cool your home, you will avoid opening the windows. This reduces the appearance of insects and mosquito bites that are so frequent during the summer months.

Improves the quality of sleep

Sleeping in a cool environment, not cold, allows the body to relax and makes it easier to fall asleep. This promotes better rest and improves the quality of sleep.

You may have heard that the noise that comes from an air conditioner makes it difficult to fall asleep. Maybe in the past, this was true, however nowadays it is not so. Not only has technology improved a lot in this regard, but also more and more devices include a night function, making the aircon much quieter than daytime use.

Keeps you energetic in the daytime

When you sleep uninterrupted you will be more energetic the next day. You will be more alert and will have a positive mindset as well. Remember that when you wake up exhaust and angry it is probable due to a lack of quality sleep.

Air conditioning helps you in this way, by improving your physical and mental health that goes hand in hand with great sleeping.

Good sleep helps you against aging

Air conditioning, believe it or not, can help you fight against aging. By lowering the temperature in your home and achieving a great sleeping cycle, your body is more likely to realise melatonin, a hormone that helps you prevent wrinkles and benefits your skin.

On the other hand, you may have heard that subtracting humidity from the environment, using the air conditioner, can cause some dryness on the skin. What you need to do is not lower the temperature extremely and keep good hydration by drinking water.

Remember that it is recommended to drink 2 litres of water a day, especially in hot months.

Contributes to weight loss

Sleeping is very important to lose weight. A study by the US National Institutes of Health found that sleeping in cooler temperatures can increase the amount of brown fat, which is a healthy fat and burns faster than white fat which is an unhealthy fat.

It can also improve insulin sensitivity, helping to reduce the risk of diabetes. Remember that you need a great sleep pattern to achieve weight loss, and air conditioning can be your best ally.

What to keep in mind when sleeping with air conditioning

Temperature

One of the basic rules for the proper use of air conditioning is temperature control. The first thing to keep in mind is that the daytime temperature is different from the night time temperature. Remember that your body temperature drops while you sleep. For this reason, controlling the temperature is essential.

Take note; a temperature between 24/26 degrees may be ideal to facilitate rest.

Maintenance

Another of the fundamental rules to use air conditioning while sleeping, and to be beneficial for your sleeping cycle and your health, is proper maintenance. Otherwise, it can be harmful to your health as a dirty filter will proliferate dirty air.

Changing or cleaning the filters is necessary to avoid the accumulation of bacteria that can cause diseases in the respiratory tract and avoid any discomfort or problem related to your health.

Also, you should be aware when it’s time to service your air conditioner, when is just cleaning and you could perform it by yourself with some maintenance tips, or when it comes the time to call an expert and perform proper maintenance to your system.

Prevention

To avoid any respiratory problems, try not to focus the aircon directly on your body. Also, do not overuse it, keep a cool temperature, and do not exaggerate the cold. Otherwise, it can be harmful to you and your family.

Sustainability

Finally, you need to keep in mind that incorrect use of the air conditioner can cause high energy consumption and therefore the quarterly energy bill will be high. Try to use it smartly,  adjusting the thermostat from 21 degrees to 24/26 degrees cuts consumption by almost half!

Another recommendation to reduce consumption is to keep doors and windows closed when it is turned on. Open the interior doors for the air conditioning to distributes evenly through all the house.

If you are looking to save energy while helping the planet we recommend an energy-efficient air conditioner that also has a temperature regulation system.

In conclusion, sleeping with air conditioning is the best option for you if you are not able to sleep at night due to heat. However, you have to keep in mind all the recommendations and good practices to make the most out of this experience.

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.

To combat the high temperatures of summer there is no better solution than having an air conditioning system at home. Especially during those hot and muggy summer days where your life keeps going but you feel exhausted by the heat.

Remember that when you choose an air conditioning system, it is very common to consider two main options; the split aircon system or the ducted air conditioning system. Also, you may be wondering what the best solution for your home is and which of these two systems is the best value at the end of the day.

If you are starting your research to make an informed decision, in this article we will go through the main advantages of each one, as well as their differences, so that you can choose the best home air conditioner type for you.

Central Ducted Air Conditioner

Typically, central air conditioners have two units; an evaporator and a condenser.

The first unit is outdoors, called a condenser, and contains the compressor, Tx valve, and other critical refrigeration components. The second unit is indoors, called and evaporator, and blows warm or cool air through the ducts in your home.

Central Air Conditioner Pros

The main advantage that central air conditioning systems have is their ability to cool down the entire house using one unit. If you have a ducted reverse cycle air conditioning system, the benefit is double. A reverse cycle central aircon will not only be able to cool down your house but also heat it up when the winter comes.

Another advantage is the quality of the air that is being pumped out through the ducts. As the majority of central air conditioning units have filters that can remove harmful pollutants and micro allergens from the air, your indoor air will be cleaner.

Furthermore, this type of air conditioning system produces less noise than mini splits systems. Most central units do not produce any audible noise in the home. Also, it is perfect if you are looking for air-conditioning spaces in your home at the same time.

When it comes to the aesthetic side of things, ducted central air is a great option. Since you will not have to have a device in each room, you will only have a grid in each space. This can be located in the ceiling, wall, or floor.

When talking about the investment aspect, the initial cost may not be as high as you think if the house already has ductwork installed. Ongoing costs in terms of maintenance may also be lower as it can be relatively straight forward.

Central Air Conditioning Cons

When you want to air-condition a single room, it will not generally be possible. In general, this type of system is designed to emit cold air or hot air throughout your entire home.

Another huge con can be in the case that you do not have duct pre-installed in the house. In this instance, the installation or initial costs can be high. In that case, a specialist should carry out the installation work as the indoor unit and ductwork has to be carefully and strategically laid out behind the ceiling.

Another con could be the fact that central air conditioning unit ducts can often leak. This leak can negatively affect energy efficiency. Another downside is that central air conditioning cools down the entire house, usually with one constantly open living area, even if you are not using the relevant living space.

Split Air Conditioning

These air conditioning units only cool the individual spaces in your home. Mini-splits are equipped with an outer and inner component as well. However, mini-split air conditioning units are best used for multi-family homes or for homes that are not capable of having central air conditioning.

The installation of this type of equipment must always be carried out by a professional. You can opt for the Split, which for each indoor unit has one outdoor unit, or for the Multi Split, which has several indoor units but only one outdoor unit.

Pros of Split Air Conditioner

The main advantage of a split air conditioner system is that the installation is quite simple. Also, each indoor unit is individually controllable when it comes to a temperature. This which each zone can be treated individually.

Also, if there is a fault with a split unit, it only affects that room or zone. This is better than having the entire house without heating or cooling as a result of one unit breakdown.

Cons of Split Air Conditioner

The biggest disadvantage of mini split air conditioning units is the investment. Electricity consumption can be higher than with a ducted air conditioning system due to having an internal unit for each room of the house. Keep in mind that these units are characterized by producing 30% more cooling capacity than comparable central AC units. This may double your monthly energy cost.

Also, the initial investment will be higher, since you will have to install an indoor unit in each room that will be heated or cooled independently.

When it comes to the aesthetics of your home, it may not be the best option. This is because it has a unit for each room. Furthermore, the noise level may increase as the fan of each unit is located directly in each room where the indoor unit is installed.

Which of the two options should you choose?

The option that best suits your home will depend on many factors. For example, your budget, your needs, the type of installation available, and the architecture of your house, just to name a few.

For these reasons, and before deciding on a split air conditioner or central air conditioning system, it is preferable to be guided by a professional or technician specialized in air conditioning systems.

A thorough and current evaluation of your needs is one of the most important parts of the decision-making process. Furthermore, a specialized technician can measure your home and verify which aircon system will suit you best.

Specifications

A ducted air conditioner should be installed when:

– You have pre-installation of ductwork done.

– You want to air-condition all or almost all the rooms of your house equally.

–  If aesthetics is an important factor for you.

– Your house is large and spacious.

– You do not have enough space outside to install more than one external unit.

It is ideal to install a split air conditioner when:

– You have not done the pre-installation of ducts or the roof space is not high sufficient to allow for ductwork installation.

– The air conditioning needs in each room are different.

– You have a small and compact house.

– You do not mind that the indoor units are visible.

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.
