Q: AC only blowing cool air, not cold

asked by on

My truck's AC is blowing cool, but not cold air.

Hi. There are many potential causes for the symptoms you are having. However, the most likely reason for your AC issue is simply low refrigerant. This can be confirmed by performing an AC performance test using a manifold gauge set. Hooking the gauges up to the AC system allows the technician to read high and low side AC pressure and diagnose the poor system performance. If both the gauges show low pressure, the refrigerant level is low. A trained technician, such as one from YourMechanic, will be able to diagnose your AC system and recharge it with refrigerant if necessary.
