DIY Car Air Conditioning Repair

ALWAYS TALK to someone about your car air conditioner who has had some experience in the car air conditioning industry, for example, technician, auto electrician, mechanic, or car restorer, before you start repairs.

Parts that may need replacing are the TX valve, the condenser, the evaporator and/or the compressor.

In this case, let’s say your compressor needs replacing.

You then order from an air con dealer a generic compressor by referring to the numbers and model shown on the label of the compressor. Also purchase from the same dealer a receiver dryer or filter to match the new compressor.

The receiver dryer will help your air conditioning system run efficiently. Remember, the Australian Refrigerant Council protocol is to replace the receiver dryer every 5 years.

When dealing with the 134a gas it requires a licensed handler to recover the escaped gas once the old compressor is removed. Mobile Auto Air will provide this service free upon request.

Now it’s time for you to fit your new compressor. To prevent inadvertently spilling new oil from the new compressor, do not remove the plugs that are attached on the new compressor until it has been fitted to your car.

The plugs relate to the suction inlet pipe and the high pressure outlet pipe. The ‘o’ rings on both these pipes will need to be replaced. If you are unable to purchase the correct size ‘o’ rings, place a small amount of ‘o’ ring sealant on each ‘o’ ring (purchased from an auto shop). Leaking of gas will be prevented if these ‘o’ rings are correctly positioned and sealed into the new compressor.

Well done!

Before starting the engine the air con system needs to be de-vacuumed to remove any moisture and then re-gassed with the correct amount of 134a refrigerant by a licensed refrigerant handler.
