What does an air conditioning compressor do?

The AC compressor pumps and pressurises the refrigerant through the air conditioning system, feeding cold air into your car. The compressor is powered by your car’s engine.

How often should a compressor need replacing?

A well-maintained and properly serviced compressor could last as long as your car does. However, as with all vehicle components, they’re prone to wear and tear. Leakage and blockage can create irreparable damage.

The law, vehicle regulations and your MOT

A **faulty air compressor **won’t affect your car’s MOT, but it can affect the comfort of you and your passengers. It’s worth keeping your air conditioning running correctly as the impact it can have on your vehicle’s fuel efficiency could affect the day-to-day cost of your motoring.

You will be advised of any other parts that may need to be replaced for the best operation and health of your vehicle. This includes replacement of refrigerant and possibly the orifice tube and receiver dryer.

What causes an AC compressor to stop working correctly?

Over time, the internal components of a compressor can wear or fail, including the seals that cannot be replaced independently. In other cases, the valves, pistons, bearings or clutch may need replacing, and it could be a cheaper option to replace the complete unit rather than each of the individual parts. Your compressor may have stopped working properly due to infiltration by dirt and debris, or from being affected by other faulty parts in the system.
