![]() ![]() Sure, your fans might still run, but you won’t feel any cooled air coming out through the vents. When the compressor fails, the whole air conditioner fails along with it. It’s what enables the refrigerant process so that your air conditioner will actually do the job it was designed to do. If the thermostat serves as the brain of your AC, then the compressor is the heart. The next question is, should you pay to have your system repaired, or should you have it replaced? Before we answer this, we have to explain the role of the compressor in your air conditioner. We let you search and book from over 1600 qualified mechanics, who eat car troubles for breakfast.So, you’ve been told (or you suspect) that your air conditioner’s compressor has failed and is the cause of your cooling system breakdown. So next time you need a service, repair or inspection, visit. If you’ve read this far, you obviously care about your car. #Air conditioner compressor repair driverTypically, a failed AC compressor won’t cause safety-related concerns but instead an annoyance for the driver and discomfort for all occupants. #Air conditioner compressor repair windowsWhile it does so, the AC compressor also draws moisture out on the defog settings, maintaining clear windows so you can see. You may think it’s designed only to keep you cool. How important is replacing your AC compressor? Proper diagnosis by approved technicians can eliminate needless repairs A leak elsewhere in the AC system can seem like a failed compressor.Refrigerant should always be recovered safely by a certified technician as releasing it into the environment is known to be harmful.The technician confirms the AC system’s operation.The AC system is recharged with refrigerant according to manufacturer’s specifications.The lines are refitted and the belt and wiring put back in place.The failed compressor is unbolted and removed, and a new AC compressor fitted.The low-side and high-side refrigerant lines are disconnected from the compressor body.The serpentine belt is removed from the AC compressor clutch pulley and the clutch is unplugged.The technician recovers the refrigerant in the whole AC system, discharging any pressure.How is AC compressor replacement performed? External leak detected by technician’s diagnosis.Broken serpentine belt from seized AC compressor clutch.Warm air blowing through dash vents with AC system turned on.Clunking noise when clutch engages instead of light click.Symptoms that your AC compressor requires replacement The clutch mechanism utilises a bearing that can fail as well.Īnd if one of the seals or internal parts in the AC compressor develops a flaw, the compressor won’t function as it should or not at all, and will need to be replaced. This cycle continues as long as the AC system is activated or the defogger is turned on.Ī small amount of oil is required to lubricate the moving components. Inside the AC compressor, two pistons attached to a wobble plate pump the low-pressure refrigerant entering the compressor into the high-pressure side. In turn, the rest of your AC system enables that refrigerant to cool the air that enters your car, but it all starts with the compressor.Īn electrically-activated clutch on the compressor engages when the system detects lowering pressure. It pressurises and circulates the refrigerant in your car’s AC system. On average, you can expect AC compressor replacement to cost $800 to $1,200 or more, depending on the make and model you drive.īecause it’s a cornerstone component of your air conditioning, your AC won’t function if the compressor is broken.Īt the basic level, an AC compressor is a mechanical pump. In many situations, the AC compressor lasts the whole life of the vehicle without requiring replacement, although failure is more likely after 150,000km. Through normal wear and tear, and possibly due to an unexpected defect, the AC compressor may stop functioning or seize. The AC compressor pressurises the system to push the refrigerant throughout. When the temperature gets steamy outside, the air conditioning system keeps your car’s interior comfortable by circulating refrigerant throughout the AC system.
