Q: Air conditioner not working

asked by on

My air conditioning is not working, though the AC has Freon. The gauges are not reading up to par. The compressor might need replacement.

Hi. It may be a compressor issue, or it could be an expansion valve that is a stuck open. A stuck open expansion valve would show a higher than normal pressure on the low side when the AC is in operation. You may want to enlist the help of a mechanic to inspect the AC problem with your vehicle.
