No getting rushed off the phone, time taken to convey info clearly. This is a family run business and it shows. Everyone there takes pride in what they do and are a pleasure to work with.“

“I needed assistance to deal with an emergent boiler service. Fred Jordan showed up the next morning and corrected the problem in no time. He then noticed my more than 70 year old steel oil tank that was on it's last legs. He replaced the tank and really demonstrated his expertise and workmanship. The price was very fair. I highly recommend Accurate Boiler.“

“We needed to replace our air conditioner unit and wanted to take advantage of the substantial rebates available from Eversource. Bill advised on the technology and recommended the correct equipment to qualify for the rebates. He installed a new heat pump system and air handler and integrated it with our existing hydro air system. Bill was very timely and professional throughout the process.“

“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!“

“It was so great to have a company respond quickly to my inquiry to have some work done. They were able to fit us in quickly, did an excellent job and were very reasonable.“

“The owner Steve goes above and beyond for his customers. Excellent service, great prices!“
