3 year old package unit heat pump outside for the downstairs of this house. . I tested the cooling (it was above 90 degrees here yesterday) and it seemed to be working properly. I turned it off and waited around 5 minutes.
I turned on the Emergency Heat and tested it. It appeared to be working properly.
I turned off the Emergency Heat and let it sit about 5 minutes. Next. I turned on the cooling to the original setting the homeowner had it on and it just blew hot air.
I tried shutting off the breakers to the heat pump thinking that it might be a computer error and that maybe it just needed to be reset.
Nothing worked. I called a local HVAC company over and they said that the capacitor and contactor needed to be replaced. . $415 out of my pocket later everything was working fine.
Any ideas at all on what might have caused this?
