Hey all, I am at a crossroads and would like some opinions on purchasing a Heat pump. I currently have a split system consisting of an Electric furnace (think 15KW) inside with a 1991 2-ton condenser on the outside. This year, we have spent approx. $600 on repairs to this system for various reasons. It has been recommended that we consider replacing the entire system. All of the local contractors that have given estimates recommend the installation of a heat pump with 15KW electric backup in the inside air handler. My concern is the negative opinions I have heard from a few previous owners of heat pumps. Most state that air source heat pumps are not a good match for our Kentucky climate which can have some cold winter stretches. On the other hand, some of these experiences were with older heat pump systems. It stands to reason in my opinion that I would save money by running the heat pump when the temperatures are mild outside. When outside temps reach a certain point, my electric backup would kick in and I would be heating with basically the same resource I currently use, obviously not at the same efficiency. However, I still think I would save money in the long run. Can anyone comment on their experience with a heat pump system? I am looking for people in climates like Kentucky or even more north. Thanks, Tim

I have 2 central ac systems (gas furnace w/ ac's about 2 tons each)in my home (have recently moved in) and have discovered that each unit has 2 filters located at the return air areas, one high at the ceiling and one at the floor approx. 20 x 20 each. the previous homeowner has left spare filters, however some do not appear to be compatable and I assume that they are from the older unit which was replaced. is it possible that there are other filter locations that I am not aware of - where could they be if so?
