Our house is 12 years old and things are starting to show their age, including the heater which serves a two story house. The fan would not shut off and I was expecting to have to wait for a couple of days for a repairman to come out. Boy, was I surprised after making the call, they were there the same day! What is more amazing is they fixed the problem and I wanted 2 updated control units and they got them ordered and returned the next day. On top of the great price and service, they were so nice and polite. I will refer them out and use them for all my heating needs.
