Adam helped us last month with complicated AC/Furnace problems in our new home. We didn't know very much about these appliances, of which there are several, but he was able to find and service each one. He also let us know the need to replace some of them in the near future and the reasons for this, and even made a diagram of each one, their locations and correct thermostat for each area of the house, etc. He was courteous, clean and understandable in layman's terms. I could not believe the time he took to track down some puzzling problems and ultimately he solved them. I would definitely trust him with our AC/Furnace problems, their replacements and so on.
