Question about Whirlwind FH-778 Air Conditioner
Installed a new Hunter thermostat a few weeks ago. All was cool (pun intended) until yesterday when the air was warm to almost hot. Called the Hunter Fan tech line. We reset the thermostat and all was ok until about an hour ago when it started blowing warm air again.

SOURCE: Hot Air from the cooler
check the a/c unit. make sure you dont have any leaks around your system. sometimes when you have a small leak it will take time to lose out of system. but you may need to charge your unit up again. Also your compressor may be out of service. check and make sure compressor is running

SOURCE: PROBLEM WITH MY AIR CONDITIONER
Is the outside unit running? if so can you feel warmer than outside air blowing from outside fan? If not your system may have a leak and pressures low. You can also check the piping to and from the unit larger one should be cold small one should be warm

Your unit may be going into a defrost cycle. If so sounds like a bad defrost board. It sends a signal to electric heaters inside to come on. Change board and sensor

You will need to replace the fan motor. Basically when the system starts running in reverse the fan motor is shot, and the electrical is telling to motor to spin one way but since the winnings are shot then are making the motor spin the opposite direction.

Assuming you are not low on freon:
I have seen this symptom caused by too much moisture in the system too, it freezes near the metering device which kills the refrigeration effect which makes it warm up, the ice melts and it starts working until moisture builds up and freezes which kills the refrigeration effect again.
