Why Your Car AC Stops Working

Why Your Car AC Stops Working

Virginia summers are no joke, and a failing car AC can make your commute miserable. Here are the most common reasons your car AC stops working:

1. Low Refrigerant (Most Common) — Refrigerant slowly leaks out over time through seals and connections. A recharge restores cooling, but the leak should be found and sealed.

2. Refrigerant Leak — Small leaks in hoses, connections, or the condenser cause refrigerant to escape. UV dye testing can locate leaks accurately.

3. Failing Compressor — The AC compressor pressurizes the refrigerant. A seized or failing compressor won't circulate refrigerant at all.

4. Clogged Cabin Air Filter — A clogged filter restricts airflow and reduces cooling effectiveness. Easy fix!

5. Electrical Issues — Failed relays, fuses, or AC control modules can disable the entire AC system.

6. Condenser Problems — The condenser sits at the front of the car and can be damaged by road debris. A bent or punctured condenser causes refrigerant loss.

7. Evaporator Issues — Less common but can cause leaks inside the cabin.
