I can not get the tech to explain to me why it would be blowing air before the heat pump turns on. Is this normal operation?
My first guess was that a saftey in the outdoor unit is opening-anti cycle timer or pressure switches. But my knowlege is fairly limited to the less sofisticated systems...thr ones that i can see, hear, touch...
Could I be wrong, and the heat pump compressor is on, but the heat pump fan is not? Could it be a redundant delay? If so, is it unavoidable or can it be corrected?
If you can get to the furnace then put your hand on the refrigerant lines.If its in defrost and compressor is pumping then the large line should be cold.
My final question, is there a good reason for not turning on the stat option that automatically flips the system from heat to cool or vice versa, as the case may be?
I dont like auto changeover because it is wasteful.But I dont dont think it is relevant here.
