Central Ac Unit Blowing Warm Air
The central ac unit is blowing warm instead of cool. The blower is (obviously) working and the outside fan is running also. But while the fan on the outside unit is running, I can hear something trying to kick on and I'm guessing it is the compressor.
The central ac unit will make a humming noise for a second or two and then it stops. Two years ago the outside unit was only humming - the fan wasn't running - and the technician changed the capacitor.
Could a bad capacitor keep the compressor from kicking on or am I facing the cost of replacing the compressor?
