How to Repair a Broken Air Conditioning Compressor?

Repair methods for a broken air conditioning compressor: 1. Add an appropriate amount of Freon; 2. Replace the power supply line clip and use sandpaper to clean the surface of the compressor terminal; 3. Reorganize the connecting pipes between the indoor and outdoor units to reduce the workload of the compressor; 4. If the air conditioning power supply is aging, replace it promptly. A compressor is a type of driven fluid machinery that converts low-pressure gas into high-pressure gas, serving as the heart of the refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it via piston movement driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle. Depending on the working principle, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.
I remember one summer when the AC suddenly stopped cooling while I was driving. I suspected the compressor might be faulty because adding refrigerant didn’t help. During my own inspection, I checked if the belt was broken or loose but avoided touching the high-pressure lines—those are dangerous. It’s best to take it to a professional auto repair shop for diagnosis. Technicians will use tools to check pressure and locate leaks. If the compressor is indeed faulty, it needs replacement, possibly along with vacuuming and refilling new refrigerant, which can be costly but prevents travel delays. Safety first—driving without AC in extreme heat leads to fatigue and increases accident risks. To slow compressor wear, avoid idling with the AC on for too long during regular driving.
