How to Repair a Car Air Conditioner Nearby?

Replace the compressor. When the pressure gauge detects that the low pressure of the air conditioning system is higher than the normal standard while the high pressure is lower than the normal standard, it usually requires replacing the compressor. Cooling issues. When the pressure gauge detects that both the high and low pressures of the air conditioning system are higher than the normal standard, it is usually due to air inside the system, requiring evacuation and exhaust. When the external ambient temperature is high, the problem is generally caused by clogged or dirty cooling fins or insufficient cooling fan speed. An air conditioning detector can be used to locate the leakage point.
I've been driving for over 20 years and have seen plenty of AC issues. The most common reason for no cooling is refrigerant leakage, meaning insufficient Freon. Start the engine and turn on the AC, listen for the compressor sound—normally there should be a humming noise; if there's no sound, check the fuse box location. If the fan isn't spinning or airflow is weak, it might be due to a clogged filter—regular cleaning can improve this. A broken compressor or blocked pipelines requires a professional mechanic who uses tools to detect pressure leaks—never tamper with the high-pressure system yourself, it's too dangerous. Check the AC condition during every maintenance session, including refrigerant levels and wire connections—prevention before summer is better than emergency repairs. Immediately find a reputable auto repair shop or 4S dealership for diagnosis and repair to avoid spending more money later.
