"Damien arrived on time and determined our issue quickly and corrected our clogged pipes. We also asked him to check out another issue. He stayed and fixed this issue as well. He also cleaned everything up before leaving. A true professional. We will definitely be hiring him again and recommending him to all of our friends. Thanks again Damien"

"The technician and electrician were both very respectful, knowledgeable, provided all options, were open and honest about why they recommend the service chosen, helped in obtaining the financial services, walked me through the entire process. The technician went above and beyond making sure the. After the water heater install was completed he performed a safety inspection on my heating system, cleaned the debris from the flute into the chimney, made a few tweaks here and there to make sure my system was performed to his satisfaction. I was extremely appreciative of his care, concern and professionalism."

"After spending 2 days trying to find someone to replace my hot water heater, Home Advisor recommended this company. They fit me into their schedule the same day and it was installed about 4 hours after my initially contact with them. Casey and Phil were great. Had them look at a couple of other minor future projects to do while they were here. Will definitely hire them again."

"Could not be happier with the install of our new propane system. They were very easy to work with Quinn answered all my questions Doug and Bernie and I forget the other guys name were a pleasure to have in my house. They did the work and the Quoted amount of time. They handled all the inspections and permits with the town. Extremely happy with the level of service and would recommend to anybody looking for heating needs. Edit from 2 years ago?. The company still has not picked up old water heater and boiler. Have called a number of times to get this done. Vicki is extremely unpleasant to deal with. Rude. Has zero phone skills. Should really look into finding a new person to answer the phones. She was basically yelling at me for asking, follow up questions. And when I I said, why are you yelling? She said so you would know if I was yelling at you. But she definitely was yelling. I really hope those phone calls are recorded. They?ve got their money. So obviously the customer service ha"

"Later, they actually sent their manager Mark to take another look who is more knowledgeable for the steam radiator system and finally found several leakages from radiator supply valves and other minor issues. They gave me a quote to replace valves and vents. Since then I have been tighten the nuts over the weekend and seems to fix most of the leakages."
