Car Air Conditioning Compressor
Repair & Replacement
Your Car Air Conditioning Compressor is the heart of your car’s air conditioning system.
Like a heart pump’s blood around your body the Car Air Conditioning Compressor pump’s refrigerant (gas). It takes the gas, pressurises it and passes it along to the condenser than to drier, TX Valve, evaporator and then back to the compressor.
Why did my Car Air Conditioning Compressor stop working?
The most common reason for your Car Air Conditioning Compressor to fail is leaky seals and inadequate lubrication. It is good practice to turn the AC on periodically so that the seals don’t dry up and stay lubricated. If you notice a change in the temperature of the air through the AC vents (not as cold as it should be), get it inspected.
What common symptoms indicate you may need to replace your Car Air Conditioning Compressor?
- No cold air from the vents.
- Clicking sound from under the engine.
- AC not working.
About your Car Air Conditioning Compressor
The AC compressor has several moving parts (including pistons and valves). These internal parts can fail, causing the AC compressor to stop working. It is common for the internal parts of the compressor to come apart and disperse metallic debris throughout the system. Consequently, it is a requirement to replace the orifice tube and the receiver dryer when replacing the compressor since some of the debris may have ended up there.
For an AC compressor to work, it needs a clutch, bearing, and an electrical connector. The clutch is driven by a drive/serpentine belt, which engages the compressor when you switch on the AC. The clutch can burn or the bearing can fail. If the bearing or clutch have failed, it is recommended that the compressor is replaced. Sometimes replacing the entire compressor with a remanufactured one can be cheaper than replacing an individual clutch or bearings.
It is also common for the seals in the AC compressor to go bad. The compressor may start leaking refrigerant and/or the AC oil. If the seals no longer hold, you will need a new compressor, as the seals cannot be replaced. A compressor may also fail if there is sludge or debris in the air conditioning system. If there is sludge or debris, the hoses, evaporator, and condenser should be flushed to get rid of the contaminants. When it is not possible to flush the parts, you may need to replace those parts.
