Radiator & Car Air Conditioning Repair Service in Perth

At AME we really care about your car and you. Here’s a short guide to how air conditioning (AC) works, why it might not work, And a few auto air conditioner repair tips. Your air conditioning system is made up of a compressor, a condenser, an evaporator (or drier), refrigeration lines and a couple of sensors here and there.

The compressor puts the refrigerant under pressure and sends it to the condensing coils. In your car, these coils are generally in front of the radiator. Compressing a gas makes it quite hot. In the condenser, this added heat and the heat the refrigerant picked up in the evaporator is expelled to the air flowing across it from outside the car. When the refrigerant is cooled to its saturation temperature, it will change phase from a gas back into a liquid (this gives off a bundle of heat known as the “latent heat of vaporization”). The liquid then passes through the expansion valve to the evaporator, the coils inside of your car, where it loses pressure that was added to it in the compressor.

If the AC is not working it might be because of the compressor, and the reason ccould be a bad fuse, a wiring problem, a broken AC switch in your dash, or the system could be low on refrigerant (most systems have a low-pressure safety cutout that will disable the compressor if there isn’t enough refrigerant in the system). We will check for all this and fix anything at bad.

Bad switches, bad fuses, broken wires, broken fan belt (preventing the pump from turning), or seal failure inside the compressor could be the cause of AC failure. At AME we will carefully inspect and replace any faulty part.
