would reccomend Custom Air over and over again. Rob is an expert technician and actually can fix your furnace as opposed to telling you to buy another one or replace parts. I had no power at all getting to my furnance, i feared the worse. Rob inspected the wiring and quickly resolved it. He clearly has master level knowledge of how these things operate and enjoys fixing them as oppose to replacing. Hes also reasonably priced and i would definitely give him a call before i start buying expensive replacement parts or buying another furnance.
