Donny and his crew were beyond professional and reasonably priced. I had inquired about a thermostat, knowing it would be a shot in the dark. Donny said no problem at all and removed the old, mercury thermostat. We got a new Honeywell that worked with our Wifi, for which was set up too! Now, not only did we save money on the rebate, but we can change the temps right from our phones. Great work!
