Michael Pierson came to our home to check out the (lack of) efficiency of our heat pump system after our electric bill had risen dramatically in December. He found the cause of the problem, fixed it, installed the new Nest thermostat we had purchased, showed me how it worked and helped me set up the app AND signed me up for a year of maintenance all for $169.00! Incredible deal and a very nice guy who seems to love his job and his employer, which I think says a lot. We have found our new HVAC dealer and would recommend them to everyone. I'd give more than 5 stars if I could.
