Best boiler installation pros near Millis, MA

"The thermocouple on my gas-fired boiler needed to be replaced, and the pilot needed to be cleaned. The tech was helpful and forthcoming with information. Took about an hour, as my boiler does not have easy access. Would hire again!"

"J.T. came to evaluate installation of an over-the-range microwave. He was very thorough and explained everything so I could understand the complexities of the installation. Very friendly and competent!"

"I originally called the company that did my regular maintenance less than a year ago. They told me they couldn't send someone out for 3 days! This in the middle of a cold snap. When I called Rodenhiser, they were able to send someone the next day. While they were not able to completely fix the problem right away - a part was needed - they were able to restore heat while we waited for the part. They came back in a few days and repaired the boiler zone controller."

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"On a Monday holiday I turned on my air conditioner and it refused to work. I went to HomeAdvisor and left my name and phone number but called a company that has worked for me before where I got a recorded message. In the meantime Burke plumbing and heating called and left me a message to call them. I called them and they said that they would send someone out that very afternoon. I needed a complete new furnace and compressor. The next day he ordered everything he needed and it arrived to be stored in my garage overnight. The next day he and another workman arrived at 8 AM removed the old system and installed the new. They were finished by 1:30 PM, cleaned up and everything worked like a charm, I would definitely recommend Burke plumbing and heating to anyone needing their service."

"From start to finish, Rodenhiser provided exceptional quality customer service. Dan on the front end, designing the combination tank less-hot water/boiler system and assisting with the MassSave program. Tyler, Dillon and the other gents on the 1.5 day of installation of our system were extremely professional and courteous. They left the worksite cleaner than when they started. It’s a thing of beauty. We love our new system and look forward to the cost savings! I’d recommend them at the drop of a hat!!"

"Amazing experience all around. Easy to schedule and to work with, good deal and amazing work installing a tankless water heater. I will definitely call for any future needs."
