How does the A/C system work?

The Air Conditioning system cools and dehumidifies the air in the passenger compartment using a refrigerant.

What kind of maintenance is necessary on Vehicle's Air Conditioning System?

Air conditioning systems require minimal maintenance. Usually just a visual inspection according to the manufacturer's recommended schedule is sufficient. Symptoms that may indicate a problem are system's inability to cool down the interior of the car on not-so-hot days, or noise coming from the engine bay when the A/C is on.

How do I know if my vehicle's Air Conditioning System needs repairs?

You will normally only be seeking service on your car's A/C system when you notice a decrease in its cooling capability or when it isn't working at all.

Components of Your Air Conditioning System

Some of the components of your Air Conditioning system include


The compressor is a belt-driven device that compresses refrigerant gas and transfers it into the condenser. It is the core of your vehicle's air conditioning system.


The condenser's primary function is to cool the refrigerator. The condenser dissipates heat released by compressed gases and condenses them into high pressure liquids.

Receiver (Drier)

The receiver is a metal container that serves as a storage receptacle for the refrigerant; also known as a drier because it absorbs moisture from the refrigerant and filters out harmful debris and acids. It is recommended that you change your drier every 3-4 years to ensure quality filtration and prevent any chemical damage.

Orifice Tube/Expansion Valve

The orifice tube (also known as the expansion valve) is a controlling mechanism that regulates refrigerant flow throughout the system. It also converts high pressure liquid refrigerant (from the condenser) into low pressure liquid, so that it can enter the evaporator.


The evaporator removes heat from the inside of your vehicle. The evaporator allows the refrigerant to absorb heat, causing it to boil and change into a vapor. When this occurs, the vapor leaves the evaporator through the compressor, cooling your car and reducing humidity. The evaporator houses the most refrigerant in the heat transfer process and harmful acids can corrode it.
