Our technicians will repair and return your vehicle to its cooling ways quickly and correctly.

The ABCs of A/C
Basically, your vehicle's Air Conditioning system consists of two major sides – high and low. Beginning at the high side, the compressor acts as a pump, moving the refrigerant (freon) through the system. The low side consists of an expansion valve that restricts the flow of refrigerant, creating pressure the system needs to ensure the expansion and decrease in temperature and boiling point.

Your A/C system has four major parts. The industry generally has two types of systems — expansion valve or orifice tube type, but they function much in the same manner.

• The compressor, mounted on the engine, is a pump that circulates the refrigerant through the system. This is the most important and expensive component of the A/C system.
• The condenser transfers heat removed from the passenger compartment to the outside air. It is located in front of the radiator, just behind the front grille of the vehicle.
• The evaporator, located near the dash or firewall, transfers the passenger compartment heat to the refrigerant, which transfers it to the condenser.
• The dryer absorbs any excess moisture from the refrigerant.

Other areas that should be inspected include the flexible hoses that connect each of the major components together, their metal connectors and rubber seals. Each of these components are a potential source for leaks and need to be inspected regularly.
