Even if your air conditioning system is one of the simplest and easiest to use, it is made up of many parts that work in sync to provide maximum comfort. Each of these parts has a specific purpose in the system and performs a specific function.


We have created this quick guide for those interested in what the main parts of an air conditioner are and how they actually work. In it, we'll note the most important elements in an air conditioning system and look at their function.


Learning about the basic anatomy of an air conditioning system and how it provides us with quality air conditioning is very helpful. This information can help you spot a potential problem earlier and resolve it with the help of an air conditioning specialist.


We'll start with the three most important parts of an air conditioner, then move on to the secondary parts.


1. Air conditioner compressor

The compressor plays an essential role in the air conditioning system. It processes the warm air and then releases it into the room cooled. How does this happen? A refrigerant gas circulates in the system, which under the action of the compressor is converted into a liquid state. During this process, heat is released to the outside.


A professional technician should check this element regularly at least twice a year. We do not recommend that you attempt to repair it yourself.


2. Air conditioner condenser

The condenser is another important part of the system that extracts the warm air and helps to pass it outside. It is made up of hollow coils through which the refrigerant passes, which then reaches the coils.

During the operation of the air conditioner, moisture can become trapped and cause corrosion in the condenser and the rest of the system. This damage is repaired by chemical cleaning, which air conditioning specialists perform. The annual maintenance is very important, as during it the specialists can determine if there is a need for such cleaning and prevent the damage of internal parts. If the process has already affected some parts, they may need to be replaced.


3. Air conditioner evaporator

The air conditioner evaporator is another major part that is responsible for completing the cooling process. The refrigerant in liquid form passes from the condenser into the evaporator to become gaseous again. This allows the cooling cycle to be closed.


If the evaporator coil is not cleaned regularly, dust and dirt begins to accumulate on it. It then starts to run inefficiently, and the air conditioner uses more electricity. You can clean the coils with a vacuum cleaner and a soft brush. If you decide to do the cleaning, be careful as the fins are prone to bending.


Other air conditioner parts


1. Expansion valve

The function of this part is to regulate the amount of liquid refrigerant that enters the evaporator.


2. Air conditioner filter

The function of the filter is to clean the air. During this process, dust, dirt and other debris are trapped in the network. This is the part you should check and clean regularly - at least once a month.


3. Air conditioner thermostat

The thermostat has sensors and a control panel. Thanks to it, you can set the desired temperature and other settings. The function of the sensor is to transmit information to the device as soon as the room temperature reaches the set degrees.


4. Drain pipes

The drainage system in the air conditioning system is responsible for draining the condensate. Maintenance of this part of the air conditioner is also essential as various debris and dirt accumulate in the pipes which can lead to clogging and leaks.


5. Air conditioner fan

The fan ensures proper ventilation and air regulation in the air conditioner. The air conditioner also has vents that should be cleaned regularly.
