Pass One Hour Heating & Air Conditioning is a great company which I have used for a very long time. I am on their annual maintenance agreement. I really liked the young man they sent out to my house this last time for a checkup. He was very nice, knowledgeable and prompt. He cleaned all of my furnace for me and everything turned out just fine. I really do like this company or I would not be using them all this time. I always recommend them to everyone.
