I have no complaints about One Hour Heating and Air Conditioning because they are very good to me. My AC wasn't working good recently, so the technician came down and put some Freon into it. Now, it's working fine. I like that they call me for appointments (because I'm in the Diamond club), and they call me before the AC and furnace have to come on--just when it's time to inspect everything. They are real friendly and very efficient there, and I like their service.
