We have been doing business with One Hour Heating and Air for quite a while, they actually installed our A/C unit a long time ago when we first moved into our home. They are excellent, professional, and I have always been very satisfied with the quality of the work they have provided us. We also have a service contract with them, meaning that about once a year they come to our home to make sure that all of our equipment is up to date and working properly. You can't mess with perfection so there's nothing I can recommend they do better. We wouldn't do anything else.
