In this article, we break down air conditioning back to its bare bones to give you an insider’s view.


Every kind of air conditioning system whether it be big or small, expensive, or cheap, new, or old, they’re all designed for the same thing – to cool down indoor spaces by replacing hot air with cold air.


Sounds simple right? Well, it is, and it isn’t.


Standard air conditioning units utilise a chemical called refrigerant, a gas that gets heated and pressurised, transformed into liquid and then back again. This is achieved when three main components work together – the compressor, evaporator coil and condenser coil. The compressor sits on the outside of the home, heats up and pressurises the gas, sending liquid through the condenser coil and into the evaporator coil.


Once the liquid is in the evaporator coil, it will cool the coil on the inside of the home. When the fan blows air across the coil, the air is cooled down and enters your home. The heat that is lost when the air is moving across the coil is sent outside through the evaporated gas. This process of transferring heat will continue until the room reaches its desired temperature.


What makes your aircon work?

The components that make your aircon work were mentioned above but for the curious, here’s a more in-depth explanation


Evaporator Coil

An evaporator coil is the mechanism that the liquid from the outside flows into and the heated gas flows out of. The cold liquid cools the coil which the air is pushed through, while passing the coil, the heat is absorbed back into the liquid, turning it into a gas and back into the compressor.



The compressor is kind of like the heart of an air conditioning unit. It turns the gas into a liquid to transfer it into the evaporator coil while also receiving the recycled gas once it’s passed through the condenser. The compressor regulates the amount of gas and the overall temperature the unit will put out.



The gas that’s come from the evaporator coil will pass into the condenser which releases the heat into the outside air usually via a fan. Once cooled again the liquid is moved back into the compressor and sent back into evaporator coil.


Health Benefits

There are many benefits of using air conditioning to your home that go beyond just making it more comfortable.


Improves Air Quality

Harmful allergens and dust particles can be removed by air conditioners with adequate filters. This will greatly improve the quality of the air that is circulating in your home and that you and your family breath every day.


Heat can be deadly

The risks of dying from heatstroke is very real today. Many people around the world unfortunately die each year during heatwaves without access to air conditioning.


Improved sleep and mental wellbeing

We all know how important a good night’s sleep is and how hard it can be to come by if we’re too hot. By regulating the temperature with air conditioning, you can avoid the stress and worry of not getting enough sleep.
