“Chris Carne was the technician who came to our condo today to repair and service our gas furnace. He did a very thorough testing of the furnace and discovered we had a faulty gas valve. His courteous explanation of what he was doing along with his nice personality made this repair a pleasant experience. We would highly recommend him for any of your service issues.”
