Hi there. I just had an American Standard hybrid heat pump, new coils, a new Honeywell thermostat installed. My blower motor worked fine so I did not replace that. Now I have an issue that I have never had with my old heat pump and it's happened about 10 times since install about 2 months ago. The heat pump will shut off once the temp. I have the thermostat set to (78) is reached. However, my blower stays on blowing. This has only happened during the night and between 1 a.m. and 4 a.m. The only way I can get the blower to shut off is by lowering the temperature on the thermostat, this makes the heat pump kick back on, and then everything runs normally again. If I try to turn the system off on the thermostat the blower will stay on, if I raise the temp the blower stays on, no matter what I did the only way I could get it to return to normal operation was by lowering the temp. Does anyone know what this could be? I have a warranty on all new parts but wanted to get some info before I called the company out here. Any help is greatly appreciated, thanks!
