I have posted multiple times here. I live in an area where there are only 3 Heating and Cooling company's, very small town. All 3 have been out and all 3 have left saying everything was fine. My house is not old, my heat pump is a 4 ton unit, zoned, ugly pictures can be found in my other posts. I am getting very depressed. High electric bills, 120 KWh a day without even heating the basement. I just want to know why the temperature will decline 6 degrees after 6o seconds into startup. Is there anyone here that could give me a answer to this question.
