“the best of the best!! They have done annual maintenance service of our system (which they installed 15 years ago). Recently the replaced the air handlers and boiler. The plumbing was museum quality. Hats off to Joe and Steve!! FIVE STARS PLUS !!“

“We recently had a leak in one of our copper pipes behind the vanity in our bathroom. Gabe came out and fixed the problem promptly and was extremely friendly and professional, and provided additional information and suggestions on what to do going forward. I would highly recommend this company.“

“Excellent, knowledgeable plumbing and hvac pro. Came within hours of our call, investigated and solved the issuein within 1/2 hour. Charge was way below expectation. Definitely would call again, and trust his expertise and meticulous style, without question.“

“Great outfit! They just helped up grade from oil to gas. This is an inherently challenging undertaking for us -- but working with JP was really a pleasure and he guided us from beginning to end -- professionally, efficiently, with patience for a zillion questions, and reassuring us that it would all work out great -- which it did! JP helped us to feel comfortable with all of the decision points -- cutting through lots of variables -- making sure we got exactly what we wanted -- and showing a lot of flexibility when it came time to schedule the actual install. I was honestly dreading it -- an old oil tank had to come out of our basement -- as well as giant original boiler dating back to the 60's -- it seemed like a lot could go wrong. But no -- the Sullivan team are all pros. A bunch of technicians came -- they worked incredibly hard and were clean and organized and highly efficient -- you instantly knew that they do this a lot -- they know their stuff -- they got everything done faster than expected and there were no "oops" moments. Our home is transformed! We really value working with a trusted local company that has pride of workmanship and who clearly cares about their customers. A rarity these days. Thank you JJ Sullivan!“
