Q: AC not working

asked by on

I put Freon in the AC unit, but the air is still coming out hot.

Hi. If the pressure in the AC system isn’t enough, the computer will never cycle the compressor on and no cold air will flow, I suggest having the car tested for leaks. If no leaks are present, a certified mechanic, like one from your mechanic, can recharge your AC system.
