Air conditioning has become so necessary that many forget that less than a century ago it didn’t even exist. Also, air conditioning has changed a lot through the time thanks to tech and all of its advances.

Just a few years ago, we used to associate air conditioning with equipment that is quite large, noisy and not very efficient in terms of energy consumption. Today, thanks to tech applied to air conditioners the improvements are truly spectacular.

With the current technology, many of the main benefits are in terms of energy efficiency, noise reduction and automation.

Still, nowadays, tech keeps redefining air conditioning and there are several changes that you will see implemented in the near future and today we will share with you.

Voice control

An air conditioner is undoubtedly one of the best allies in the summer due to the high temperatures. But this can be much more comfortable if it has functions that facilitate its management and control, such as voice control command.

In most of the current air conditioning equipment, or better known as the new generation air conditioners, you will see an integrated voice command that with a remote control it will allow you voice control. Also you will see voice commands through an application.

Filters self-cleaning

Air conditioners tend to accumulate a lot of dirt in their filters. This is because the filters are designed to prevent the passage of particles or dirt into the air that is expelled in the rooms.

This is why filters get filled with residues that need to be cleaned. Keep in mind that in general cleaning the filters should be done regularly. Many people forget about this important step since it is not directly visible and on many occasions it is usually believed that it is not necessary.

To avoid this, there are already air conditioners that offer this function. The idea is that the same device does the cleaning of the filters automatically. A very innovative technology that guarantees us to always have our air conditioner clean which maximizes air quality.

This also has great benefits regarding health because the accumulation of dirt and bacteria may cause diseases. With filters self-cleaning diseases could be avoided. Also, with self-cleaning, manufacturers ensure more hygiene in these appliances, and therefore fewer health-related problems for users.

Heat pumps with R32 refrigerant

Heat pumps are heating and air conditioning equipment that is used in a very efficient way for the AC to work with very low energy consumption. However, in the past refrigerant gases were used, which used to be quite harmful to the ozone layer due to their high pollutant level.

Today, the laws are much harsher in relation to air conditioning and it is for this reason that manufacturers are looking for alternatives not only to comply with these laws, but also to contribute to the planet.

A heat pump is in itself really efficient, but mixing it with R32 refrigerant gas makes it even more attractive since this gas is one of the least polluting.

Intelligent control system

Smart climate control replaces your AC remote control. It allows you to control the temperature of your house from wherever you are. There are two ways the Smart AC Control can operate to control your air conditioner:

In thermostatic control

Smart climate control operates directly on your AC. This acts as a room thermostat and measures the current temperature in the room. It also turns your AC on and off to maintain the temperature you’ve set.

In non-thermostatic control

The intelligent climate control sends a temperature setpoint and settings to your AC. Your air conditioner directly controls and maintains the room temperature based on the measured temperature and the fully programmed setpoint temperature.

Heating, cooling and DHW units

Air conditioning systems that have heating and cooling incorporated in the same unit are  getting more popular day to day. This is because many manufacturers have realized that creating integral AC units avoids people’s inconvenience of buying another system.

For example, there already exists an AC that was designed to cover heating, cooling and domestic hot water consumption. This makes it a device with multiple functions and definitely a great solution for many homes that are looking to have a system that covers their needs.

Bladeless fan

A fan without blades is one of the latest innovations that we can find in the market regarding air conditioning. Not only is it quite an aesthetic equipment, but it is capable of cooling the rooms with great power.

The fans without blades actually do have them but they have them hidden in such a way that they are not visible to the user.

Air conditioning and ventilation by aerothermal energy

The air conditioning and ventilation sector has revolutionized a lot due to aerothermal energy, as it works with a heat pump extracting energy from the subsoil in the form of latent heat.

Keep in mind that air and ground are excellent carriers of energy and at the same time they are renewable. In order to get that kind of energy you need a mechanical compression cycle and an electric compressor.

Remember that when it comes to ventilation and energy changes will be several through time for air conditioning as manufacturers are always trying to use more eco friendly elements.

Controlled mechanical ventilation

Controlled mechanical ventilation is a device itself which goes integrated into the house or building. It works with central ventilation that forces the extraction of air to renew and thus guarantee the quality of the indoor air.

Controlled Mechanical Ventilation makes it possible to efficiently manage energy consumption when renewing the air inside a building.

In conclusion, the future of air conditioning is changing and you are able to get the most advanced air conditioning for your home already. Things like air purification, built-in cleaning systems and controlled ventilation are revolutionizing the market and you can be part of it.

Air conditioning, either portable, by splits or by ducts went from being a luxury item a few years ago to becoming a necessary appliance in any home.

When buying an air conditioner you are not only looking to control your home temperature, you are interested in other factors. For example, if it is enough to serve your home, if it is eco friendly or if it has any advanced technology that gives you more comfort.

Truth is, there are several factors when it comes to buying a new air conditioner to make a good purchase decision.

Define your criteria

First of all, if you live in an apartment or a house inside a condominium, you should be sure that you have the required permission to implement air conditioning at home. Keep in mind that the installation of air conditioning involves changes in the exterior appearance of your home and sometimes noise pollution.

Also, you should check the condition of your home’s insulation before choosing your air conditioning. If necessary, perform a thermal balance at your home. Keep in mind that air conditioning can be very expensive daily if the home is poorly insulated and prone to heat loss.

Furthermore, it is essential to choose your air conditioning according to your needs. Ask yourself what you are going to use it for. Is this a one-time or an ongoing need? Do you need air conditioning just for a room in the house or for the entire house?

Determine your needs

The type of air conditioning that you will acquire for your home depends on different factors.

Type of accommodation

You will not choose the same type of equipment whether you live in a new apartment or an older house. Knowing the quality of your home’s insulation is essential to invest in a high-performance air conditioner.

Do not hesitate to bring in a professional to assess the energy performance of your building before making the investment decision.

Weather conditions

Your air conditioning must adapt to the climatic conditions of the region in which you live. For example, when the summer arrives and in your region, it is particularly hot, your air conditioning system will be required to operate continuously. In this case, you should choose an air conditioner that has the operation power that you need.

Space to be air-conditioned

Defining your needs will allow you to buy the ideal air conditioner for your home. You have to ask yourself what is the number of rooms you want to air-condition and calculate their surfaces. There is no need to acquire oversized Air Conditioning, just adapt it to your needs to avoid wasting energy.

Main types of domestic air conditioners

Portable air conditioning

The most basic air conditioning type is the portable air conditioner that does not require a machine outside, just a tube that expels the hot air to a window or other hole.

Its main advantage is that it can be moved from one place to another as long as it has an outlet for the tube, that they are not careful and do not require installation, but their price is high and they are not very powerful.

Wall and ceiling split

Split air conditioning is the most common air conditioning type. They are relatively inexpensive and offer a wide variety of power capacities. A device is installed outside that is connected to the interior appliance.

Split type air conditioning can be embedded in the wall or the ceiling and you can install as many splits as the house requires, always depending on the power of the external machine.

One of its main advantages is that it makes little noise and also the hole is relatively small and they are easy to maintain.

On the other hand, their installation is more difficult and expensive, and they cannot be installed in some areas of the house. Also, for the ceiling split air conditioning, it is necessary to take into account that they are powerful but their installation is expensive and they can be noisy.

Window air conditioner

The window air conditioner has its functional parts inside a “box”. It is installed in a hole in the wall with one part of the device facing outwards and another part facing inside.

Its advantages are that it has a low cost of installation and maintenance, but it consumes more than other appliances, it is more noisy and it is necessary to cut a hole in the wall to install it.

Ducted air conditioners

The ducted air conditioning is centralized in a single unit, which distributes the air through the ducts to the grilles, which lets the airflow into the room.

It has great advantages like uniform air conditioning throughout the house which is perfect for large spaces, but also it is more complex and expensive.

ceiling mounted cassette type air conditioner

Reverse cycle air conditioning

Finally, every day we hear more about reverse cycle air conditioning. This system consists of a new technology that regulates the power of the device while maintaining the ideal temperature without the need to turn it off and on and also it provides heat and cool.

A system specifically designed to be more energy-efficient, which means increasing the efficiency of the device while providing great energy savings.

Which air conditioner is for each room?

Now it’s time to choose, after reading all the information above, ask yourself what are the main objectives for you to acquire an air conditioner.

If you want to improve your comfort in the summer in a living room, invest in mobile air conditioning for occasional use or a fixed mono split air conditioner if you plan to use it daily.

However, if the area exceeds 35m2, you should rather opt for the bi-split or multi-split option. But if it is a larger place, it is recommended to opt for ducted air conditioning

For example, for a bedroom, you should choose the quietest air conditioner. Prefer the split air conditioner since the noise is mainly generated by the outdoor unit on this type of system.

Do not hesitate to be accompanied by a professional to find the air conditioning that best suits your home and your expectations.

Residential air conditioning has become an essential appliance in our homes, especially at certain times of the year when the heat becomes intense. Furthermore, with reverse cycle air conditioning, you can adjust the temperature as you want.

But despite the essentiality of what air conditioners do, what we want to show you today is the technology behind air conditioners and how it works, as it may be less complex than you think. Understanding it will also help you deal with AC problems, understand breakdowns, and choose one model over another when acquiring your AC for the first time or changing it.

What does its operation consist of?

First of all, it must be said that a normal air conditioner works thanks to thermodynamics applied to the use of a particular type of gas with specific characteristics. The most widely used currently, because it is capable of guaranteeing great savings from the energy point of view, is R32 gas.

The operating mechanism of an air conditioner consists of a constant process of increasing and decreasing the temperature of this gas, through a compression and decompression system.

An air conditioner is made up of two parts. An external one, which is essentially the engine from which the process starts and which is installed outside the home and an interior one, commonly called “split”, is the part that ends the process, putting cold or hot air into the space where it is installed. The internal machine can be wall-mounted, portable, or channelled.

What are the parts of an air conditioning system?

Contrary to what many believe, air conditioners do not generate cold air and “expel” it, but rather extract the heat from the air in the room to be heated.

The operation of this basic refrigeration circuit where a refrigerant gas runs through a circuit of copper pipes changing from a gaseous to a liquid state and vice versa as it passes through the different components of the system.

The constant changing in the state of the refrigerant is what causes the thermal exchange that allows the air conditioner to extract the excess heat from the air and to condition the room.

air conditioning service maintenance


Indoor unit

Also known as split, this element is essential to understand how the air conditioning works. The indoor unit of the air conditioner, which is the one located inside the room to be cooled, contains an evaporator.

This part is responsible for extracting the hot air from the room and transferring this same heat to the refrigerant gas. Inside this unit, there is also a fan to distribute the air once cooled.

Outdoor unit

The outdoor unit is in charge of expelling the hot air from inside the room to the outside. It is made up of three parts: compressor, condenser and expansion valve. The compressor is the most important element in the refrigeration circuit, the one that consumes the most energy and the one that determines how the air conditioning works.

What the air conditioning compressor does is compress the gas that comes from the evaporator in a gaseous state until it becomes a liquid and heats it. The compressor works according to the speed set by the temperature sensor controlled with the thermostat.

For this reason, when the indicated or programmed temperature is reached, the compressor slows down, even turning off.

Refrigerant gas

The refrigerant gases change their state from liquid to gaseous, absorbing, in this process, the heat from the room.

Expansion valve

The expansion valve causes a loss of charge in the refrigerant and a drop in gas pressure and temperature. This process is similar to that used by sprays: inside there is a gas in a liquid state and when pressed it sprays and comes out cold.


The thermostat is an electronic component that is used to regulate the operation of the air conditioning. Optimal use of thermostats can help you save up to 30% on the energy consumption of your air conditioning.

What are the phases of air conditioning?

The refrigeration cycle is the set of processes by which the refrigerant gases pass from one state to another until they return to their initial condition. This cycle is made up of four phases or processes.

young women turn on air conditioning


Expansion phase

The expansion is the first phase in which the refrigerant is in a liquid state and at high pressure. Also, it is stored in the outdoor unit of the air conditioner. As it is necessary to send it to the indoor unit to achieve the cooling effect, this process is done through the expansion valve.

The purpose of the valve is to reduce the pressure and temperature of the liquid, leaving it in optimal conditions for the next phase.

Evaporation phase

Inside the indoor unit, there is an evaporator, which is what allows the liquid gas to evaporate. After this process, the liquid, already converted into gas, gives up its cold to the air in the room to be heated, where it is distributed thanks to a fan.

Compression phase

During this third phase of the cycle, the refrigerant, in gaseous mode, returns to the outdoor unit to become liquid again. For this reason, it is necessary to compress the gas, which goes to the compressor located in the outdoor unit, where it will be subjected to high pressure to change its state once again.

Condensation phase

In this last phase, the high-pressure steam circulates through the condenser. The heat escapes to the outside and the coolant condenses, turning back into liquid. Afterwards, the refrigeration cycle begins again.

What happens when the air conditioning is turned on?

When the air conditioning is turned on, the two machines, the exterior and the interior begin to work simultaneously, starting a hydraulic circuit formed by copper tubes, through which it circulates, that is, the gas, which plays the fundamental role of heat transfer.

Once the gas has travelled through the evaporator, it will return to the compressor and the cycle will begin again.

Does an air conditioner cool and heat in the same way?

You may be wondering at this point if the process is identical when the air conditioner produces warm air instead of cold air.

First of all, for this to happen an air conditioner with a heat pump is needed, therefore it is used for the winter season.

One of the most important factors to feeling comfortable at home is temperature regulation. For example, in summer, if the rooms accumulate too much heat, it becomes uncomfortable to be able to rest or do any task indoors and it can happen the same with extreme cold.

This is why it has become so important to choose your air conditioning wisely considering all the needs that you have at home regarding temperature and to help you make a great decision we have created a guide of what you should know before buying an air conditioning.

Keep in mind that before making an AC buying decision, make sure that the chosen system has the following basic characteristics: adjustable thermostat, at least two fan speeds and that it has an optimal energy regulation that stops the system when not cooling.

Basic functions of air conditioners

Air conditioners can perform various functions. The basic one is cooling. However, reverse cycle air conditioning is gaining popularity which will allow you not only to cool or heat the room but also helps you control the humidity level inside and dry or moisten the environment if necessary.

It is also important to know that modern air conditioners are equipped with appropriate filters that guarantee the purity of the air in the house and additional functions, for example, motion sensors or Wi-Fi control.

Buy before the heat hits

It is important to buy your air conditioner in other seasons but in summer to prepare your house for the hot season because in summer their price rise. Keep in mind that you should not opt for the first air conditioner you see in the market, but the one that best suits your budget and your home.

Not everything is for everyone

As we said before, before buying an AC and installing it, it is important to determine which is the most appropriate system for your home, something that varies depending on the region of residence, the characteristics of the home and its location.

Therefore, before buying air conditioning under the advice of family and friends, it is better to check which one will suit you best and consult with an expert because each home is different and what works in one may not work in another.

UV light

Some air conditioners incorporate an ultraviolet light capable of disinfecting the air, eliminating living organisms such as bacteria, fungi and viruses, as well as polluting particles, allergens and bad odours, disinfecting the cooled air.

This UV-C light is inside the device, being safe for health since it does not emit light to the outside so in case you want all of its benefits you should make sure the air conditioner you will buy has it.


Filters are included in all air conditioners and thanks to them you can improve air quality, which is essential for those who suffer from allergies, asthma or want to avoid the smell of tobacco.

So in this case, you need to make sure that the air conditioner you choose has the level of efficiency you are looking for, depending on the space.

CADR (Clean Air Delivery Rate)

The amount of air that a filter can purify in a specific size or space is linked to the efficiency of the filter and it is called the Clean Air Delivery Rate. The higher the CADR index, the more filtering power the appliance will have and the better the air quality in the room will be.

Refrigerant gas

If you want to help the environment and help create a more sustainable planet, you must take into account the refrigerant gas used by the appliance.

You should choose an AC whose refrigerant has a low environmental impact and excellent thermodynamic properties. Keep in mind that there are devices that do not use any type of refrigerant gas at all.

Energy efficiency

Energy efficiency is related to energy consumption, power, functional capacity and respect for the environment and you should check on the appliance before buying it. Keep in mind that on March 1, 2021, the new energy label for household appliances came into force in Europe and probably it will extend worldwide.

The classes A +, A ++ and A +++ disappear. The new scaling goes from class A, most efficient to class G, least efficient.


Keep in mind that there are air conditioners that include, in addition to the cold function, ventilation options to promote airflow, dehumidification to reduce and control the humidity of the environment and heating so that you have that coverage for the winter.

Different AC types

Even though we all are faced with different types of air conditioning systems like window units, wall units, portable systems, central air conditioning units and ducted systems, it is convenient to know the characteristics of each one and see which is the one that best suits your needs and budget.

senior choosing air conditioning

Energy expenditure

It is very important to estimate how much energy the air conditioning you choose will consume because it is one of the main items on the electricity bill. For this reason, it is necessary to find out which AC’s generate the greatest electricity savings and at the same time provide a good service.

Truth is, technological advancement has allowed new systems to no longer spend as much energy as they used to and for this reason if you have an old air conditioner you may consider changing it.


The capacity of air conditioning systems is measured in British Thermal Units (BTU) per hour. The higher that number, the more power the appliance will have. On average, 5,000 BTU / hr is ideal for a 40-square-meter room.

However, the size of the room is not the only thing that determines the number of BTUs required, since the number of windows, the orientation of the room, the natural light, the insulation and some other factors also influence.

Trust the professionals

Remember that it is important to consult with a professional before making an air conditioning buyer decision. We will be glad to help.

Air conditioning makes life easier for us and it also brings many benefits to our life at home and to our life at the office. Independently of the type of air conditioning you choose for your business, they have many advantages.

It is easy to recognize offices and workplaces in which, unfortunately, there is not a good environment and not necessarily referring to the relationships between the different workers, but the temperature and airflow at the office and that’s a mistake, as air quality has a great impact on people indoors.

Maybe you are wondering what kind of impact it has. The reality is that poor air quality can worsen mood, performance, and also lead to illness and irritability. To solve it, the best option is to have great ventilation at work. This means that a good air conditioning system can help and a lot to the workers and the company.

According to scientists from the Technical University of Denmark, good air quality can improve productivity by 10%. Certainly, a great reason why it is advisable to invest in air conditioning is that in the long run, it has more benefits despite the cost of installation.

However, the main reason why an air conditioning system is necessary for workplaces is for the health of the workers, which is also positive for the business owners since air conditioning air helps prevent diseases and also leads to fewer illnesses, which also means a decrease in sick leave.

What can happen in a work building if there is not good ventilation?

If your office has not had good ventilation you can feel exhaustion, worse cognitive abilities, and it can even increase the possibility of allergic reactions. It can also lead to general tiredness, headaches, throat irritation and stinging in the eyes.

Indoor air quality in work environments is largely dependent on workplace ventilation. Mechanical systems can combat the main air pollutants that can originate in working areas. Typically, the main causes of poor quality air at work are:

  • The location of the building. If it is located near large avenues or highways, the property can be affected by many sources of dust and particles.
  • Dangerous materials. Certain types of indoor plastics and specific materials can worsen air quality and be harmful to your health.
  • Poor air circulation. If it is not ventilated well, an indoor room can create what is known as stale air, which would significantly affect the health of workers.
  • Indoor air quality is highly dependent on the ventilation system and its ability to replace low-quality air with fresh air. This means air conditioning can prevent moisture and eliminate the presence of pollutants in the air. In addition, it may be able to improve the energy efficiency of the building and also offer more sustainable climate control.

team working design

Improve ventilation at work and in industrial environments

Ventilation in offices is very important, but in other professional environments, air quality can be even more problematic. For example, ventilation in industrial environments. In addition, the industry generates a lot of heat and humidity, so they have to be kept on a reasonable scale.

In both harsh professional environments and offices, ventilation at work can be ensured by the following actions in addition to air conditioning:

  • Minimize processes that generate heat and produce water vapour. For example, screens that can be used in front of heat sources.
  • Increase indoor air renewal and circulation if it gets dirty frequently
  • In the case of offices, the installation of reverse cycle air conditioning can help you renew the air, help combat low temperatures in winter and heat in summer.
  • Reverse cycle air conditioning also blows constantly filtered air. In no case does the Remember that all the air is filtered, so you can breathe better indoors than outdoors.
  • The indoor temperature should not be very high in winter or very low in summer.

What are the benefits of air conditioning for offices, workshops, offices, factories and shops?

Improve the comfort of your employees

If in the workplace the cold is intense or the heat is excessive, the comfort level of the employee’s decreases and this affects their work performance. An employee who works in an uncomfortable place produces less and it can affect the business.

Reduces the presence of insects and parasites

A good air conditioning system reduces the presence of parasites and insects in the environment. These animals do not like low temperatures and that is why if you want your office to be free of mosquitoes choosing to install a good air conditioning system is a smart move.

Reduces hydration needs

In a very hot work environment, people’s sweating increases and therefore, their need for hydration increases. If you do not want to dehydrate or see your workers suffering from dehydration the best you can do is have air conditioning at work, mainly when the summer heat gets intense. In this way, the air conditioning will improve the efficiency of your staff.

Fewer allergies

An air conditioning system incorporates filters, so in this way, if there are people allergic to pollen or other particles, it is very useful especially when spring arrives. With air conditioning, there will be fewer allergic reactions.

people working modern office

If the temperature remains within the advised parameters, the air quality in the office, shop, factory or workshop and the respiratory problems of the workers will be reduced. Remember that the recommended temperature for air conditioning in summer is 24 degrees.

In conclusion, an air conditioning system ensures that the staff will work better, take fewer breaks, enjoy greater comfort and have a better mood, which will lead to the workers performing better and producing more. In facto, as we have seen, buying an air conditioner is not an expense, it is an investment.

When summer arrives, many people think about how to save energy while using air conditioning, even though AC it’s a key part of surviving the hottest summer hours. The reality is that savings can be seen in the long term if you take action from the first moment you start using air conditioning in your home.

Ice Blast, a highly-recognized air conditioning company located in Brisbane, Australia, highlights that even from the purchase of air conditioning, you can make a significant change by purchasing an energy-efficient air conditioner that helps with long-term energy savings,

But many other tips can help you save energy while using air conditioning at home, such as the ones we are going to name below.

What type of air conditioning should I buy for my home?

Currently, in the market, there are different types of air conditioning and each of them has a different installation, power, refrigeration and operation.

Portable air conditioning

This type of air conditioning does not require prior installation. This equipment is louder than others and although it is cheaper, its operation is less efficient.

Split air conditioning

Split air conditioning is the most common AC out there. Also, it is cheaper than, for example, ducted air conditioners. It is easy to install, its system consists of an outdoor unit with a compressor and an indoor unit that can be installed on the wall or ceiling and also it is a silent device.

Multi-split air conditioning

The main difference with the single split AC is that it can have up to 8 indoor units while having a single outdoor unit. These air conditioners have great power and are suitable for big homes with more than 2-3 rooms.

Keep in mind that even when the installation is similar to the single split one, the indoor units work individually.

Ducted air conditioning

This type of air conditioning requires a more complex installation through a false ceiling but it can offer great air conditioning features as well.

How to save power while using my air conditioner?

Check the energy efficiency label

When purchasing an air conditioner, you must check the energy efficiency label on it. The best option is to opt for the one that has an A label. If it is A +++, the energy savings will be approximately 40%.

Keep in mind that appliances with this rating are priced higher than those with a worse energy rating. Still, it is not worth saving on the device when, in the long run, it will cost you more in terms of consumption.

Use medium temperature

It is advisable to set a temperature between 20 and 25 degrees in summer and 20 and 22 degrees in winter. Beyond this temperature, the air conditioner will start to consume more electricity. This will cause the electricity bill to increase between 6% and 8%.

This temperature is not only ideal when it comes to consumption, but it is also the best for your health. It is important to note that the difference between the outside temperature and that of the house should not exceed 12 degrees.

Program the air conditioning

One of the options to save on the electricity bill is to program the air conditioning to turn off, especially when you are not home or at night. Sleeping with the air conditioning is not the best option, but if the user does, it is best to program the operating hours to avoid excessive consumption.

You can also activate the Eco mode if your air conditioner has this option as you can save up to 30% on energy consumption.

Make sure a good installation is performed

When installing the air conditioning it is very important to define where the appliance is going to be placed. Avoid putting it in areas where the sun’s rays hit directly as it is preferable to put it in a shady place.

Also, make sure that you do not cover the airflow of the air conditioning to pass as this will decrease the efficiency and it will be reflected on the energy bills.

Perform regular maintenance

Like every household appliance, the air conditioner also needs maintenance. You can perform a really deep maintenance once a year but also you should keep the filters clean regularly.

It is not hard to do it as cleaning can be carried out with water and any cleaning agent or you can just replace the AC filters if your air conditioner works like that.

Natural ventilation

Natural ventilation consists of openings, doors and windows that allow the circulation of the air between the interior spaces of the house. It is highly recommended, especially for climates with controlled temperatures, which means that it is best to do this if you do not live in an area with extreme temperatures.

In this way you can turn on the air conditioner only if it is really necessary. Also, you can control the temperature by closing or opening the curtains and changing them with ones of different materials when it is necessary.

For example, in winter you can put ones of thick material while in summer you can put ones that cover you from the sun.

Thermal insulation

The most important thing to do to avoid energy losses is to use high thermal insulation materials at your home. This kind of material will help to equalize the temperature from outside and the temperature from inside as this works as a barrier.

If you want you can try to insulate the ceiling, doors and windows of your home by using materials such as polyurethane, expanded polystyrene, mineral wool among others.

Keep in mind that you can save a significant amount of money in the medium and long term by having good thermal insulation. This is because if doors and windows are well-sealed, it will ensure that the temperature generated by the air conditioning is maintained, without cold or heat entering the property.

We hope that you found these tips useful. Remember that when it comes to air conditioning it is better to consider long-time savings than savings you can make just when buying the AC system.


There are many different types of air conditioning systems. We are sure you have heard about portable air conditioning, central air conditioning and in this case, we are going to go through all the information you should know about split air conditioning systems.

What is Split system air conditioning?

The split air-con system is one of the most bought types of air conditioning available on the market and one of the most widely used today in private homes.

The split air conditioner consists of an outdoor unit known as the condenser, which is installed on the facade or on the balcony of the house and an indoor unit called the evaporator that cools the air.

To install the indoor unit of a split air conditioner it is necessary to drill the wall to connect the pipes with those of the outdoor unit and install a drain. The installation of this type of air conditioner is easy, but not advisable to perform if you are not a certificated air conditioning technician.

How does split air conditioning work?

A split air conditioner separates the hot and cold sides of the system as follows:

The cold side, made up of an expansion valve and an evaporator, is placed inside a unit that is commonly known as a console. This unit is installed in the environment to be air-conditioned.

The hot side, known as the condensing unit, is on the outside of the building. The unit consists of a cylinder-shaped spiral tube heat exchanger. Inside the exchanger, there is an air blowing fan, a weather-resistant compressor and a control system.

This system has evolved over the years as it has a low cost and also promotes noise reduction inside the house.

On the other hand, in buildings, shopping centres, and in other businesses, the condensing unit is usually on the roof. However, there can also be smaller units on the roof, each connected to the interior of the building by separate consoles, which cools a specific area of ​​the building.

What is a multi-split system?

Multi-split air conditioners work in the same way as split air conditioners, but the main difference relies on how many indoor units can be installed.

Inside the house, up to eight indoor units can be installed in different rooms, allowing the temperature to be regulated in each of them independently. In addition, it is possible to place different types of units in each room according to the needs: wall unit, cassette type or ceiling.

What are the advantages of split air conditioning?

It is silent

As we already said, the split system is divided into two units: the condenser, which is installed outside, and the evaporator, which is inside which means you won’t hear the noises as they will stay outside.

Great Variety of Sizes

With capacities ranging from 7,000 to 80,000 BTUs, split air conditioners are perfect for homes of different sizes.

Energy saving

If you are looking to save energy while keeping comfortable in the summer then you should consider acquiring a split system. If you compare a split and a window air conditioner with the same load capacity, the split will save up to 25% of the energy consumed, doing the same work.

This number increases dramatically with the implementation of Inverter Technology, reaching even 60%.


Split air conditioning units uses little space at home and the hole you must do in the wall for the  installation is smaller compared to other types of air conditioners. No major damage is done to your wall and also maintenance is not as expensive as you may think.

Great Aesthetic

If your home decoration is important for you and you are worried that a split air conditioner may disturb your home aesthetically then worry no more.

The design of a split does not affect your decoration in any way, moreover, split air cons are designed so they can also become an ornament while helping to create a pleasant atmosphere.

You can also match the colour of your device with the paint on the wall it will be installed on. In addition to white, there are options in black and silver tones to choose from.

Air filters included

Those with respiratory diseases know how important it is to maintain air quality. With that in mind, split air-cons have integrated purify filters with bio-active agents that eliminate odours, impurities and microorganisms.

As a result, you will have a much comfortable and much healthier breathing environment.


Split air conditioning types

Window Split Air Conditioner

It is a square box containing all the functional parts of the system. To install it, a hole must be made in the wall so that in this way one part of the device is located on the outside and the other half of the device is on the inside.

The installation of a window split air conditioner cost is low and the maintenance is really easy but they consume much more electricity compared to other split aircon types, however, it could be said that these types of air conditioners are in disuse.

Split wall air conditioner

These air conditioning systems are currently the ones that are being installed the most since the advantages are numerous in relation to the window ones. They are also usually cheaper. The unit in which the compressor is installed is located outside the building and it is connected to the indoor unit in which the evaporator-condenser is integrated.

The advantages of the split wall air conditioner are that they are not usually noisy and at the same time they are very aesthetic devices, especially if we look at the latest generation, and they are also easy to maintain.

However, the installation is usually more complicated than the installation of window air conditioners. For this reason, the cost of carrying out an installation is higher than other models. In addition, installing them in specific places can be difficult, as in the case that we want to do it in prefabricated walls.

Split Air Conditioner Floor-Ceiling Console

They have a higher capacity, compared to split wall air conditioners, but their operation is similar. When talking about the installation, we must mention that it is more expensive and complex.

The advantage of the split console ceiling air conditioner is that they have a larger capacity that ranges from 36,000 to 60,000 BTUs, and therefore highly recommended for bigger places.

Air conditioning has become a must in our homes due to summer heat. However, many people wonder if air conditioning is good or bad for their health or if it can put their family’s health at risk. The truth is that, contrary to what people believe, by installing air conditioning at home you will have many advantages and some of them will positively impact your health.

For example, temperature changes occur so constantly in the city, that it is not surprising for anyone that we get sick more and more often. Sadly, we do not have a remote control to change the climate to our liking, but we do count on air conditioning at home where we can change the temperature according to the circumstances.

Ice Blast, an air conditioning company that offers residential and commercial air conditioning services in Brisbane, Australia, highlights the main benefits of air conditioning like the reduction of humidity, the increase of the air quality, and the reduction of mould.

Reduces high humidity

The most important health benefit of air conditioning is that it reduces the humidity in our home. It is much healthier to live in a home without humidity because it is related to mites, dust mould, heatstroke, and dehydration.

Although there are other ways to reduce humidity and keep your home cool, having an air conditioning system is the best way to reduce high humidity.

Reduces asthma attacks

People who suffer from asthma should put special attention to the air in their homes as it should be a safe place for them. By using air conditioning at home you will be able to reduce the chances of asthma attacks.

This is achieved by filtering dirty air that may contain dust mites, pollutants, or allergens, as well as removing any moisture that we can find at home. Do not forget to change the air filters, otherwise, the air conditioning will generate dirt that may affect you as well.

Remember that it is important to clean the air filters once or twice every two months.

Increase air quality

Air conditioning increases the air quality making it easier to breathe.

From dust to bacteria, our indoor air can become a health threat due to inadequate ventilation and overheating. We can develop coughs, colds, headaches, and fatigue. With air conditioning, we can improve ventilation and control the temperature of our home.

Reduces the risk of dehydration and heatstroke

The cause of dehydration is a lack of water and liquids in our bodies. Our sweat contains water from our bodies and in this way, the more we sweat, the more water we lose and the more vulnerable we are to dehydration.

We can prevent this by installing air conditioning at home and enjoying having an AC at our office. Remember that fresh air in your home reduces sweating and lowers your body temperature.

Help you fight insects and parasites

Did you know that having air conditioning reduces the number of insects and parasites at home?

Insects and parasites are not only annoying, as they disturb our daily life, but they can also transmit diseases.

Air conditioners stop insects and parasites by cooling our home, in this way it creates a cool atmosphere for those insects that prefer a warm climate and cooling our body temperature so that we are less desirable to mosquitoes.

Help you sleep better

When we go to bed we expect the climate to be cozy for us to sleep like babies. The worst that can happen to us is tossing and turning in bed, turning the pillow, and not achieving REM sleep.

The next day we may feel more tired and angry because we lacked sleep due to the heat. In this case, the best way to have a nice sleep is to have an air conditioner.

By using your air conditioner at night we lower our body temperature to achieve more restful and fresh sleep. Remember that the correct use of air conditioning eliminates any bad effects we can have at night due to the climate just by setting the correct room temperature for us.

Clean odours and fumes

Air conditioning helps keep odours from fumes, dirty air, or cleaning chemicals and other odours that build up in your home away. By cleaning the air at home and eliminating the dirty ones we are destroying odours or chemicals that can directly affect our health and our lungs.

Decrease work stress

When you work, the last thing you need in your life is more stress that can be caused by heat on a hot day. Thanks to the air conditioning, you can create a good work environment and works more comfortably.

Fight mould growth

Without air conditioning, your room can get humid, which helps make your room susceptible to mould. The health benefit of air conditioning is to preserve a dry atmosphere and thwart any traces of mould.

Gives you a better life quality

Finally, keeping a room with fresh air will help you feel better and be happier. Instead of complaining about the heat, you can be happy at home with your air conditioning and a comfortable temperature which increases your well-being in general.

In conclusion, taking into consideration the air from the outside enters our homes through windows; and that this air contains dust, pollutants, mites, smoke among other particles, cleaning the air is imminent.

Also, inside the house, unpleasant odours such as tobacco and food may accumulate disturbing our comfort. Air conditioners circulate the air and filter it, removing all these particles. In this way, we can breathe cleaner air at home, which is especially recommended for people who suffer from allergies or respiratory problems.

Remember that air conditioning should be a complement to the home and not the determining factor for the well-being of your health.  For this reason, elements such as windows or doors are fundamental to favour proper insulation.

When you have a business it is really important to offer quality products or services, the decoration of the place and good customer services. But those factors are as essential as offering comfort at your store for people to feel cozy, comfortable and enjoy every time they come in.

For this reason, choosing the best air conditioning for your business is an important task so we will give you some key factors to consider for you to do it properly either if it is your property or if it is a leased property. Just keep in mind that if it is a leased property you have to be clear of who is responsible for the HVAC system.

Also remember that before choosing the right air conditioning, you must know the dimensions of the room and clearly understand how these systems work. This will help you when deciding to choose the most comfortable, useful and practical air conditioning according to your needs.

Know the urban regulation to choose air conditioning for businesses

Some specific rules are depending on the city where you want to install the air conditioning. You should choose an air conditioner that exactly executes these guidelines so that you do not have any inconvenience.

In some cities, you may have to consider elements such as carbon monoxide concentration and aesthetics of outdoor devices, so you need to do this research.

This is very important to know because it goes hand in hand with choosing the ideal air conditioner for your business. In Australia the government has their regulations, to know about the regulations for your specific city you can consult an expert who knows about the local regulations and learns about the different models that you will find on the market.

The interior design of your business

The size and decoration of your business are important when choosing the air conditioning you need. For example, in restaurants, a ducted air conditioner is generally the most used one. It goes located on the walls and the ceiling because in this way they do not have such direct contact with people, and blend better with the environment.

On the other hand, for closed spaces, or smaller sizes, a ductless air conditioner is the most common one and also it is important to consider choosing an air conditioner that emits the least amount of noise possible. Perhaps in a large space, the sound can be imperceptible, but the closer people are to the aircon, it will be annoying.

The functionalities of the equipment

There are a lot of features that the most up-to-date air conditioner have. These features can make it easier for you to choose the right air conditioner for your business. Some of them have an automatic shutdown, which saves energy and improves the efficiency of the appliance.

A lot of air conditioning systems have energy efficiency factors that reduce energy consumption and are great for those people that want to lower operating costs and do something for the environment.

Also, you can find reverse cycle air conditioning systems which means that you do not have to buy other appliances to cool down or warm up your business, you will have everything in one system. If that is not your thing you can also find independent heating and cooling systems on the market with saving functions.

Just remember that proper maintenance of the HVAC system is vital to ensure that it works properly. Also, you must place it correctly so installation is also a key factor for your device to extend its lifespan.


If we want to know how to calculate the air conditioning for your business, the first thing you must consider is the square meters of the place.

For example, for a place of 30 square meters, you will need an air conditioner with between 2000 and 3,000 frigories. Or for 50 square meters, which is a large space, you will require an air conditioner between 4,000 and 5,000 frigories. To verify this information you must look at the energy efficiency label.

Although this is a correct estimate, to know exactly how many frigories you need you to have to take into account other factors in addition to the meters or directly contact an expert who can  help you with the calculation:

  • The size of the room
  • Ceiling height
  • The number and size of the windows
  • The orientation
  • The amount of light
  • Thermal insulation

The air conditioner type

To know which air conditioner to choose, it is important to know the types of air conditioner systems you have at your disposal and which are the most suitable for a business.

Ducted air conditioning

Ducted air conditioning installation requires a false ceiling so that it is not in sight. It works with a system of tubes that transport the cold air and grids arranged in different places that allow the air to escape. They are very useful for large spaces as they distribute the air in different places effectively.

These systems are attractive for industrial decorations in which you want to leave the ducts in view, but they are also discreet, since when they are located on false ceilings.

Split air conditioning

It is very useful for air conditioning independent spaces or the ones that have more than one room. These systems are located inside the room to be air-conditioned, and also have an outdoor unit. They are comfortable and although they are visible, the large number of models and designs will adequately accompany the decoration.

You can also use multi-split equipment, with several devices installed in a single system, so that you can get the best out of your split type air conditioning.

Cassette type air conditioner

To install a cassette type air conditioner you need to have a false ceiling or a space in which it can be embedded.

This system has two important advantages: they are very efficient and reduce energy consumption. They are also compact, allowing to reduce the aesthetic impact they may have.

They are the most recommended ones for large offices, large commercial spaces and large restaurants, as they allow the entire space to be air-conditioned quickly.

In conclusion, there are many factors you have to consider before investing. We hope that with this guide you will be able to find the best air conditioner for your business and do not hesitate to contact us if you have any questions.

With the arrival of the summer, many people face the need to buy an air conditioner, because with the heavy heat in Australia, even with the effort of trying to keep cool without air conditioning it becomes necessary.

For this reason, it is important to know what are the different options that you have in terms of types of air conditioning and their characteristics. Remember that buying an air conditioner system represents an investment and it is better to make sure you opt for the best option for your specific situation.

What are the types of air conditioning and their benefits?

Portable equipment without an outdoor unit

This type of equipment does not require installation, unlike splits or heat pumps that require the placement of an extractor outside, in the facade or window. Simply place the hot air extractor tube manually in a window.

Window air conditioner

A window unit can be considered a compact machine because it has an indoor and outdoor unit in the same unit. This represents an advantage in terms of installation.

How it works is that it takes the internal section takes air from the room to be cooled and drives it through a small grill located on the front of the equipment. Then, in the external section,  it takes air from the exterior and heats it even more to expel the energy that it has absorbed from the interior when cooling.

The main advantages are that it has a low installation cost and it is easy to maintain. On the other hand, they tend to consume more electricity and they can be noisy.

Split air conditioning equipment (wall)

The wall split air conditioner is the most common one since they have many advantages over the window systems and are relatively inexpensive.

The split air conditioner has a compressor unit that is located outside and it is connected to the evaporator equipment inside through tubes, so the hole to be drilled in the wall is relatively small.

The variety of power offered is very wide and the noise levels are very low, also its design is very aesthetic, especially for the latest generations. Another advantage is that maintenance is easy.

On the other hand, the installation is more complicated than in the window system it is more expensive. Keep in mind that these types of systems are difficult to place in certain places, such as prefabricated walls.

Split air conditioning equipment (ceiling)

Its operation is similar to the wall one, but they tend to be of greater capacity. Also, its installation is more expensive and complex.

As an advantage, it is very suitable for large spaces because you have high capacity in one single device, but it tends to be a bit louder and has a higher cost of installation.

Ducted air conditioning

The Ducted air conditioning is an air conditioning system, generally centralized, that is embedded in the false ceiling of your home.

The distribution of cold air, or hot if it is a reverse cycle air conditioner, is carried out through hidden ducts also located in the false ceiling that ends in strategically placed grilles.

Multi-split air conditioning

Finally, the multi-split air conditioning is a split system with one outdoor unit and several indoor units, which allows you to cool down several rooms with a single outdoor unit.

What are the things that you need to know when buying air conditioning?


We are not talking about the electrical power it consumes, but rather the cooling power it is equipped with.

The need for more or less power will be determined, not only by the surface of the room that you want to acclimatize but also by the following main factors:

  • Orientation of the room towards the south or how it faces the sun.
  • The insulation, if the room has or not a completely correct insulation system, or it is deteriorated or deficient.
  • The use of the room, if it is intended for a large number of people or just one or a few.


The amount or intensity of noise is measured in decibels (dB). Currently, most devices have a fairly low level in terms of the noise they emit during operation. However, some models make less noise than others.

A device with these characteristics should not exceed 45dB to be considered silent. If this is an important aspect for you when deciding on one model or another, the advice is to ask for the characteristics of the aircon and opt for the one with 5 stars.

Cost and energy label

A mistake that is usually made when purchasing an air conditioner is to look at its initial sale price, and not pay enough attention to its consumption. This consumption will be, after all, the one that will determine the true cost of our air conditioning system in the long term.

Therefore, it is basic for you to consider the different labels or energy classes that are available. Keep in mind that an air conditioner can be in use for many hours, mainly in periods of high heat and therefore, consume a large amount of electrical energy.

In this way, the A +++ energy class will be the best possible option for you. Although a lower-class model may be cheaper to buy at first, the higher power consumption will eventually result in a more expensive option.

Also, you can opt for an energy-efficient air conditioner with an ECO mode, which many models have today since it allows you to use the same device with lower consumption.

For you to know what the total investment will be, consider the annual cost, where the sale price is contemplated, with a period of 10 years as average life, and sum it up with the cost of consumption.

In this way, you will be able to compare, more correctly, some models with others.

Refrigerant Gas

Refrigerant gas is a main factor to consider.

The R410A is the gas that has been used the most in recent times, and therefore the one with the greatest supply. But the greatest disadvantage is that the tax assigned to it is higher, and is in the phase of disappearing.

On the other hand, the R32 gas is the one to be used in the future and is more respectful of the environment, also it offers higher efficiency. The disadvantage is that currently, the offer is lower compared with the ones run by R410A.

Installation and maintenance

Finally, it is highly recommended that the installation of an air conditioning system be carried out by an accredited professional and the cost of this also has to be considered when buying your device.

On the other hand, proper maintenance and cleaning of the air conditioner will be essential. This will help you prevent allergies, and eliminate pollen, other particles.

The design of the device will be important in terms of facilitating access to the filters, to carry out cleaning.

If you want to cool down or heat your home the more obvious choice is to buy a reverse cycle air conditioner, but at a certain point, it can crash your green soul and you may be wondering, how to be responsible with the environment and at the same time do not give up comfort?

Let’s face it, having an air conditioner at home gives us extreme comfort but it is not a green practise considering all the energy that it uses and the carbon dioxide emissions it produces every year. However, it is possible to not give up your comfort and at the same time add your little grain of sand to the environment.

It is true that at the beginning it could represent a higher initial investment if you choose an energy-efficient air conditioner, but at the end of the day, it is worth it. This is because you can reduce home energy usage by 20 to 50% by going green in the cooling department.

When it comes to air conditioning, going green is almost guaranteed to pay for itself and it is not only the energy saving that is beneficial, the benefits extend to a healthier home environment for you and your family, a reduction in fossil fuel consumption and the happiness of knowing that you are doing a part in creating a better and more responsible world.

Key factors to watch out for the environment while using the aircon

Some things have to do with the device itself like choosing an energy-efficient air conditioner, but other things have to do with its usage, for example, you can have less air conditioner usage.

Tips for an energy-efficient air conditioner

Buy a high-efficient air conditioner

This is the first tip and the most obvious one, replacing an old air conditioning system will help you reduce costs and energy consumption because an old device, even worst if it is not well maintained, will be consuming a lot more energy than it should.

By changing it you will be saving energy by 20 to 50%, but take into account that the new system should be highly energy efficient. To do this you should be looking for a SEER rating of 14 or higher in ducted air conditioners and an EERE rating of 10,7 for window units.

Get an air conditioner of the right size

Remember that getting an air conditioner that is too small or too large for your space is a waste of energy as it will run inefficiently. What you want is an air conditioner that works properly and that saves energy, also it should dehumidify well, which is impossible if it is constantly turning on and off.

For this reason, it is important to bear in mind what is the size of the place that you want to air condition before buying an air conditioner device.

Install programmable thermostats

You won’t have to remember to turn the AC up or down with programmable thermostats. This will help you reduce energy consumption because this will adapt to the exact temperature that the room requires.

Keep in mind that this will reduce your home cooling costs by 3 to 5%.

Man adjusting thermostat at home

Avoid other sources of heat

Put heavy curtains if the sun is too intense to reduce unwanted passive solar heat gain. Also, move all the appliances that produce unnecessary heat and that you use not so frequently to the garage or basement.

This may include clothes dryers, dishwashers or ovens. This doesn’t mean that you won’t be using your appliances, but you will relocate them to a place where the heat production will not interfere with the work of the air conditioner.

Get advantage of zoning

Consider installing a split system that lets you individually regulate the temperature of each room of the house. This not only will help you reduce the overall energy consumption but this will also be more efficient and comfortable for the members of your family.

Not everyone likes to have the same temperature in the house, some people may want a colder or a warmer temperature than others.

Tips to reduce the air conditioning use

Increase your home insulation

One of the best investments you can make to make the most out of your air conditioning and reduce its use as much as possible is to insulate your home. If you are going to build a home then the best option is to insulate it with concrete forms. This means that the insulation will be in the home structure.

However, if you are insulating an existing home your best option is to use spray foam as in this way, you will maximize energy efficiency.

Install ceiling fans

Installing ceiling fans is not a huge investment and this allows you to eliminate the need to run the air conditioner on cooler days, also on warmer days, a fan will allow you to set the thermostat a few degrees higher.

In case you use a reverse cycle air conditioning system for winter as well, a ceiling fan will help you distribute warm air which will help you reduce the costs of air conditioning.

Use natural ventilation

Natural ventilation uses the natural forces of wind to deliver fresh air into your home. You can use it to your advantage by opening the windows to create a steady flow of air in your home.

If the hot weather is too intense, then you can open the windows at night when the air is fresh and this will also help you clean the environment from dust and pollution.  Turning your aircon on all the time without proper ventilation not only will make you spend more energy, but worse, it can be harmful to your health.

Remember that having an air conditioner is not bad, but it is important for you to use it consciously.

Buying an air conditioner is an important decision that will affect positively the comfort, way of living, and even health of you and your family.  This is why this decision is something that cannot be taken lightly.

Take into consideration that an air conditioner at home guarantees better rest, relaxation, mental and physical health, and even increased productivity if you work from home.

On the other hand, if you buy an air conditioner that doesn’t meet your needs you can encounter some annoyances like low energy efficiency and discomfort.

So, before buying your air conditioner, do your research and read the following factors that you should consider to make the best decision.

What air conditioners to choose from?

The most common types of air conditioning systems are the following:

  • Split system

It has a good performance and aesthetic design that does not clash.  This one is the easiest to install.

  • Multi-head system.

They consist of several split indoor units in different rooms, all connected to the same outdoor unit.  This system is used when it is difficult or impossible to install multiple outdoor units.

  • Portable

It can be used in different rooms because of portability and does not need installation.

  • Ducted system

It is important to have ceiling space to install ducts that distribute the cold or heat in the house.  They do not alter the aesthetics much because indoor unit is not visible.

What to consider?

The size of your place

The size of the place is an essential factor to decide which air conditioner is the best fit for you.

The power of the air conditioning system, typically in kilowatts, must go hand in hand with the size of the room.  For example, a very large room cannot be cooled by a device with a small kilowatt rating.  Likewise, a device with many kilowatts would be wasting power in a small room.

For this reason, it is more important to know the power required by the rooms to be air conditioned to buy the device.  It is not complicated to calculate it – just ask an AC expert.

Remember that the higher the power, the more you will have to pay.  That is why it is important to bear in mind that choosing a device with more power than you need will not mean better air conditioning, but simply a higher cost upfront and in your monthly energy bill.

Specifications of your place

It is not enough to know the size of your place, you will also need to know other specifications like the impact of the light, how many windows are in your home, where they are located, and how many people usually spend the time in each area of the house.

Also, you should know about the weather of your location, the orientation of your house, how many degrees it is exposed to the sun, the square meters of windows and doors to the outside, and even the length of walls on the facade.

In general terms, the worse the energy rating of the property, the harsher the climate, the more exposed the house is to the sun, and the more people live in it, then the more powerful the air conditioning required.

The installation distance

At the time of installation, you not only have to take into account the place, but also the distance.  This is because the greater the distance between the indoor unit and the outdoor unit, the lower the efficiency of the system will be.

For example, an installation with 10 meters of separation represents a loss of performance of between 3% and 5%, and a 15 meter separation represents a loss between 7% and 10%.

Also, when it comes to the outdoor unit, its location is very important.  Being able to have adequate ventilation is essential.  For example, if it is installed near a wall, you must ensure enough suitable distance for the air to flow easily.  Its is also better to have it in a shady place where possible.

The difference in temperature from being in direct sunlight or being in the shade can be from 5ºC to 10ºC.  This difference can result in up to 20% excess consumption and we are sure you will want to prioritize energy savings.

Energy saving

Talking about energy saving, the amount of energy used by an air conditioning system is another aspect that also must be taken into account, especially to contribute to the environment and at the same time-saving in electricity consumption, which leads to a significant reduction of expense in the long run.

Remember that energy efficient air conditioners have a cycle that goes on and off less frequently and tend to have less wear and tear over time.

Also, because they perform so well, they don’t need to be replaced as soon or as often as less efficient systems.  So, an increased lifespan is an amazing reason to get an energy-saving system and know exactly how to choose one.

controlling an air conditioner

In conclusion, as we have seen, you need to consider several factors to choose the most suitable aircon system for your home.  The size of your place and its specifications, the installation distance, and how much are you willing to spend on your new aircon at the moment of buying it and in the long run are key factors to make a decision.

Remember that a wrong choice can lead to excessive electrical costs and poor system efficiency, so make sure you research your options and/or find help with an expert if you think you need so (or just want to save some time!).
