The different air conditioner parts and functions are the most important part of your home comfort system. It is imperative that you know what these parts do in order to maintain complete control over your AC. This blog post from our professional aircond service technicians from Puchong will discuss the different parts that make up an air conditioner and its functions.


The evaporator is the part of an AC that actually cools the air. It does this by absorbing heat from the surrounding environment and releasing it into the refrigerant gas. The refrigerant gas then travels to the compressor, where it is pressurized and turned into a liquid.

Condenser coil

The condenser coil is located outside of the building and absorbs heat from the surrounding environment. It does this by using a special type of metal, which acts as a resistor when it’s heated up. Heat flows through the metal quickly to reach the air inside your house or office, where you are much cooler.


The compressor increases both internal pressure and temperature while also ensuring that there is enough refrigerant gas flowing throughout all parts of your AC system. This allows for efficient cooling over time without constantly having to refill the machine with more refrigerant gas. The compressed liquid then moves on to pass through an expansion device, allowing it to be turned into a hot gaseous state again so it can boil back into its original form: pure refrigerant gas.



The thermostat controls the AC so that it only runs when necessary. This way, you don’t have to worry about wasting energy or wearing out your machine too quickly by constantly having it on and off again. The majority of modern-day thermostats are programmable, so they can turn on before you even think to reach for them!

Drain pipes

Finally, the drain pipes at the bottom of your AC unit ensure that excess water can escape and not collect inside. This is important to do since standing pools of water in any part of an air conditioner will cause it to corrode and rust very quickly.

The filters in an AC filter out dust and other debris that could potentially get into the machine. They help increase air quality by preventing harmful particles from making it through to your breathing space, which can cause allergies or even worse conditions such as asthma attacks.

The New Understanding

This blog post has given you information on what an air conditioner does and how it works. You’ll also be able to identify the different parts of a unit and their functions. With that knowledge in hand, you can make more informed decisions about your cooling needs and which type of system is best for your home or business.
