Greg did a great job! we had a power outage / surge that fried the controller for our boiler - therefore no heat at 10pm on a frigid night. Within 25 minutes of my call, he called me and said he would be at our house in approx 10 minutes. He showed up on time and got the boiler repaired in about 45 minutes. Great Job. Thank you for the professionalism, skill, and responsiveness!
