For two generations in my family, I have used Pass One Hour Heating & Air Conditioning. That's nearly 40 years! I belong to their club. The last time they came out was for the annual service call. They checked the furnace for the upcoming Winter. They did a good job--a Very good job! The technicians at Pass One Hour Heating & Air Conditioning always come out when they say they are going to and the work is always completed in a timely manner. I really like that they do not try to sell you more products that you really do not need. I highly recommend them!
