AC Running but Not Cooling? Causes, Checks and When to Call
If the indoor fan runs but the air is warm, check the thermostat, the air filter and whether the outdoor unit is running. An outdoor unit that hums but does not spin usually has a failed capacitor or fan motor. If everything runs but cooling is weak, a dirty coil, low refrigerant from a leak or a failing compressor are the likely causes.
