After waking up on a Sunday morning to a cold house, I started to panic. New heater? If not that, how much for the repair? My husband and I called Kevin and we quickly to try to get on Monday's schedule of calls, and we were surprised with his return call an hour later. He talked us through what the possible problems were and instructed us on something we could do to fix the sensor. It worked! Kevin saved us a fair amount of money. He's also gained our trust and he'll be receiving our business from now on! Thanks, Kevin!
