The air conditioning unit in your vehicle operates similarly to a refrigerator. Your vehicle’s air conditioning unit is designed to move heat from the inside of your car to outside of it. Your vehicle’s air conditioning unit has six major components:
- The refrigerant: carries heat. In modern cars, refrigerant is a substance called R-134a. Older cars’ refrigerant is called r-12 freon, which is more expensive and difficult to find than R-134a.
- The compressor circulates and compresses refrigerant within the vehicle’s cooling system.
- Your vehicle’s condenser changes the refrigerant from gas to liquid and expels heat from the car.
- The expansion valve (sometimes called the orifice tube) is a nozzle that simultaneously drops the pressure of the refrigerant liquid, meter its flow and atomize it.
- Your vehicle’s evaporator transfers heat to the refrigerant from the air blown across it, cooling your car.
- The receiver or dryer filters your vehicle’s refrigerant and oil, removing moisture and other contaminants from them.
When your air conditioning unit is not working as it should please call us for an appointment and one of our trained air conditioning specialists will inspect your car’s air conditioner, all lines, the evaporator and the compressor for leaks and wear.
