An easy guide to the main air conditioning components

In general, we tend to associate our air conditioners with indoor air cooling – but in reality, they do so much more. The purpose of installing an air conditioner is not only to cool or heat a room but also to dehumidify and filter the air we breathe. How are all these things possible? Together with the compressor, expansion valve and evaporator, there are a few more other components working hard in all this air conditioning process. So let’s take a closer look at them.

Air con filters

We all want to breath clean air, which is why air filters are very important for your air conditioning system. Located in the indoor unit, they are responsible for the air quality in your home or office. Technically, air con filters fight and remove most of the air pollutants that circulate through the air which might otherwise be harmful to your health. When they are dirty, filters lose their efficiency, causing health issues and high power bills. That’s why you should ensure regular good quality maintenance based on the manufacturer’s recommendations.


Refrigerants are equally important for your air conditioner’s operation. Basically, refrigerants make air conditioning possible. Contained within the coils of an air con unit, these liquid agents cool and dehumidify indoor air.

Whilst there are many types of refrigerants out there, few of them actually meet criteria related to costs, performance and sustainability. Nowadays, due to an increasing trend towards environmental protection, the Australian Government has started HFC phase-down in January 2018.

Air con thermostats

Finally, a thermostat acts as a ‘control centre’ of your air con unit, enabling you to set the temperature manually or automatically. Depending on your preferences, the thermostat is constantly checking the temperature of the air until it reaches the set point. Next, the thermostat sends a signal to the device to stop working. Once the sensor detects that the temperature rises again, the air con will resume cooling down the air.

Effectively solve your air conditioning problems

As you can see, all air conditioner components are linked to each other and play an important role in the air conditioning process. That’s why we highly recommend you keep them in good working order so that you can enjoy uninterrupted hours of comfort, all summer long.
