Hi: I`ve posted before in regards to my Heat Pump blowing cool air while in defrost...well the Tech`s finally came and their solution was to install an outdoor tstat on my Heat pump...now the heat pump will not work below 32f or 0c....my electric strips will do the heating....the problem started when the heat pump was defrosting the electric strips were not coming on so the fan in the handler would blow 55f air...at first they suspected a reversing valve...but later ruled that out..at what point should the heat pump be shut off? Is the straight electric going to be effiecient enough?:confused:I have 1200sf raised bungalow R2000 with air exchanger... My Heat Pump is a Armstrong Air Concept 1000....I am using a White Rogers Tstat 1F79...and the air handler is also a Armstrong Air with electric heat... the Tech eluded to the fact he wasn`t to familiar with Armstrong wiring:eek:

I have a RHEEM 4 ton central heat/air unit I belive to be around 6 or 7 years old, (thats what th eprevious owner told me). Well all summer the AC would run NON STOP and the house night get down to 75deg if I was lucky. I had it checked out and the guy cleaned it and checked the pressures and said everything was fine its just really hot out.... Well everyone else I know if there air runs ALL DAY even on a 100 deg day the house will be 60 deg inside. Anyways, its now cold outside (only about 40-45 at night) and the house will not get above 70deg at night. The heat runs NON stop at night and the AUX heat(im guessing that stants for auxiliary) will come on and stay on for quite a while and when it does come on it makes a awfull sound outsude at the unit for about 2 seconds. It will blow heat for a while then the air will turn cool, then it will blow heat then cool ect. Very sorry for the long post just trying to describe this problem. Thanks alot
