We have had no problems with One Hour Heating and Air Conditioning. They have been nothing but polite and professional. They come in, do their job, and provide excellent service. About two years ago, they installed a new central air conditioning unit, and their service is why we've called them back since then. Because of water in our basement, they recently had to come out and assist us with our hot water tank, and furnace. They needed to order a few parts, but once they did, they came back and finished their work. They did a wonderful job, and we would use them again.
