One Hour Heating and Air Conditioning is very accommodating with their appointments and schedule them very quickly. The service person who helped me was very courteous, and I was very comfortable having him in my house. He did a great job replacing the motor in my furnace and checking my fireplace for leaks of any kind. I've used them for a couple of years now, and I think they are very thorough, very courteous, and very easygoing and very easy to work with. Not only that, but they are also very knowledgeable: I have gained information about my furnace and also my gas fireplace from talking with them.
