How Does AC Work?

Air conditioning (also called aircon or AC) is made to cool, heat and filter air.  To do this, it extracts air using fans into the indoor “evaporator” unit, where it passes through the filter of the unit, such as a Titanium Apatite Deodorising Air Purification filter (approved by the National Asthma Council). These filters trap most airborne particulates and decompose odours while absorbing and deactivating bacteria, making them perfect for turning stale air into fresh air.

After the air has been filtered, it circulates around coil structures that are heated or refrigerated based on the temperature in the room compared to your desired warmth. This works because the coils pump mixtures of special gasses that turn to and from liquid in order to transfer heat from the indoor unit to the outdoor unit. It is a common misconception that air conditioning takes air in from an outdoor unit and exchanges it through the buildings indoor units. Actually, it is a far more complex process whereby the indoor unit acts as the mouth and lungs of the room, with the outdoor unit acting as a brain that ensures each connected indoor unit is at the proper temperature.

All of this is controlled simply through a wall-mounted thermostat or the Daikin app, which allows remote control from your phone, tablet, car & more.

The Condenser Unit

The outdoor counterpart to your stylish interior device works with your evaporators to keep each room at the ideal temperature. The large fans in these machines quietly ventilate excess heat and cold from the intricate system of liquid and gass filled coils within, maximising efficiency. The power capability, features and more need to be matched with your interior units, so most customers leave selecting the condenser up to our qualified engineers. 

Our experts select the condenser unit that suits your kitchen air conditioning needs, so you get to pick how many units you want and where plus the style.

The basic concept for how air conditioning works is that a gas is condensed into a liquid by the cold air outside. This cool liquid is then evaporated back into a gas when on the inside, as the heat in the air is transferred into the pipes where the liquid is, heating up the liquid as described before. When the heat goes into the pipes, it subsequently cools down the air inside and this is what you feel coming out of the face of your air conditioning. It all boils down to one idea: absorb energy (in this case heat energy) in one place and release it in another.

The process of treating the temperature, humidity, cleanliness and distribution of the air is very similar in the way it works to that of a refrigerator.


Our air conditioning offer precise temperature control giving you the ability to create the perfect climate for you. Not only does the cooling properties provide comfort on hot days, but it additionally helps you to feel fresh and energised, even when there are extreme conditions outside. This makes it perfect all applications, however it is particularly perfect for home offices as we have found that the majority of people find it very difficult to work in extreme temperatures. In short, having air conditioning can boost your productivity in home offices while making the rest of your house that much more habitable.


While the most common view of air conditioning is that it is there to cool the climate down to a habitable temperature, the vast majority of air conditioning units can heat too. Any air conditioning unit is a heat pump and so the process that it uses to cool your homes is simply reversed. It is much more environmentally friendly than all other types of heating and therefore adds to the eco-friendly nature of the air conditioning unit.


Our air conditioning units produce clean, healthy air and they are all equipped with filters that remove dust, pollen and smoke, to name a few items. The level of filtration can be increased as necessary to provide an extra safeguard for people with allergies. All new air conditioning systems are made in such a way that they will never have stagnant water in them and so there will never be the location for diseases such as Legionnaires’ disease to become established. This leads to much safer, clean environment.


In cooling mode, an air conditioning unit dehumidifies the air, creating a lighter atmosphere. This feature is particularly important to people who suffer from chest infections or pneumonia as this means that there is a greatly reduced level of water vapour in the air. Furthermore, a correct level of humidity limits the growth of parasites like dust mites, and moulds, which gin has a positive effect on people with allergies. Around 40% to 60% humidity is said to be a comfortable level in which to live. Importantly, having a reasonable level of humidity increases the lifespan of your household appliances.



Ventilation is important in summer to keep your house from getting stuffy. Ventilation takes the inside air out, and replaces it with fresh air from outside. In the mid-seasons when the air conditioning is not completely needed, the ventilation system works independently. It can be installed with or without the air conditioning system.
