My experiences with One Hour Heating and Air Conditioning have been excellent. I have been using them for years, and the last time I had them out, my air conditioning unit had frozen up. I called them up, and their technicians came out and fixed the issue that same day. They have a great preventative maintenance program where they service the unit in the spring, along with the furnace in the fall, to make sure they're ready for the upcoming seasons. I will absolutely use them again.
