Heat pump not warming the house
We bought a house a few months ago and it has a heat pump that is about 10 years old. The house is about 3000 sq ft and every room is cold. I have never even heard of a heat pump before this, but it doesn't seem to make the house warm even when the temp outside is well above freezing. I had the temp in side set at 75 degrees but it never gets above 70 degrees. Even when it cycles to electric heat the air coming out of the vents is cool. Could there be something wrong with it or is this what I can expect with a heat pump? I am nervous about switching it to emergency heat because of cost. Does using emergency heat raise the electric bill significantly?
