I called up One Hour Air Conditioning and Heating because I had a dryer that needed to be running. I've fixed refrigerators, hot water heaters, but despite my best efforts, I could not get this thing to run. They sent someone out the same day, and not only did he get it fixed, but he also showed me a trick of the trade. He was very thorough and showed me what to do if it happened again. I was very pleased and very happy with him. He was professional, pleasant, and from now on if I have any issues, I will be calling them.
