The AC compressor is the heart of your car’s AC system—it moves the refrigerant that AC operation depends on through the system. There are a number of issues that can lead to the failure of the compressor in your vehicle’s air conditioning system, including:
Lubrication loss: There are only a few ounces of lubricant needed to keep compressors working properly, so even a small loss can compromise normal operation. If there’s a leak or if the lubricant has become contaminated and broken down, the compressor will eventually stop working. A loss of lubrication can happen when refrigerant is leaking elsewherLeaks may occur in points where hoses and pipes connect, the compressor shaft seal, the evaporator, or the condenser.
Seized clutch: A compressor clutch allows the compressor to rotate only when it needs to (rather than have it stay constantly engaged with the engine). When it doesn’t turn when the clutch engages, you may hear squealing sounds.
If your compressor is failing, it’s usually more economical to have it replaced rather than have parts in it repaired or replaced. The experts at Ramona Tire & Service Center will do a thorough inspection of your vehicle’s air conditioning system, including a comprehensive compressor check.
