The Main Parts Of A Car’s A/C System

Car air conditioning system

Your car’s A/C system works to regulate the temperature and ensure proper air circulation within your cabin. Each of these components plays a vital role in keeping the system working, but do you know what they are?

When your car’s A/C system malfunctions, the root cause can usually be narrowed down to one specific part or a few parts, making it important for you to familiarize yourself with each of them. Read on to find out more about the essential car’s A/C parts to pay attention to!

Compressor and Compressor Clutch

The compressor works by distributing refrigerant throughout all parts of your car’s A/C. As the first point of contact that refrigerant passes through, the compressor is highly important for maintaining a normal airflow within your car’s A/C system. The compressor clutch is a pulley that connects your compressor to a crankshaft of your engine.

Condenser and Condenser Fan

Next up, we have the condenser. Here, refrigerant changes form between the gaseous and liquid states. Condenser pipes are typically curved in a fin-like shape to assist refrigerant in changing forms at a higher speed. The condenser fan works by blowing air throughout the condenser, ensuring that cooling can take place within it.

Filter Drier

In contrast with the cabin filter, which works by trapping dust, dirt, and other contaminants in the airflow of your cabin, the filter drier is located within the receiver drier of your car’s A/C. Its function is to capture contaminants carried by the liquid refrigerant.


The evaporator absorbs heat when the refrigerant passes through the expansion valve. One thing to take note of is that evaporators are prone to refrigerant leaks. When refrigerant has the chance to escape, this can affect your A/C’s cooling function over time.


Your vents can typically be found under the dashboard of your vehicle. They work to circulate cool air throughout the cabin. It’s important for drivers to clean the vents regularly, removing any dirt that may have accumulated here as this can compromise airflow in the long run if not removed.

Expansion Valve

In the expansion valve, refrigerant changes form from liquid to gas. This valve connects the filter dryer and evaporator, and also serves to regulate the amount of refrigerant flowing through the system.
