"Excellent. The serviceman arrived on time, was knowledgable. He explained what he was doing. He went right to work and completed his work in an appropriate amount of time. Very pleased with their work. Already set up an appointment for the fall heater tuneup!"

"David helped me install Heat Pump Water Heater that I purchased from Home Depot. It was his first time installing a heat pump water heater but he made sure it gets installed as per code and right way. He worked with me to install stop valve in the end."

"Damien arrived on time, was very hard working, charged an exceptionally fair price, and did an outstanding job. When he left, everything was spotless. He replaced a kitchen faucet, installed a new bathroom faucet/shower head, fixed a running toilet, and even showed me what to use on stubborn hard water stains that I was unable to remove with all the usual methods. We also had him install a second hose for the backyard and replace the existing outdoor spigot. When we redo our bathroom, we will definitely call Damien."

"I cannot recommend these guys enough! I am not a patient person, when it comes to work on my house. They EXCEEDED my expectations! Their install was professional, well communicated, clean and efficient. Work was done while my twin babies were home, and they were incredibly accommodating. Their service people have been quick to reply to every question I have had after install was completed. I, honestly, will never have to shop around again - Comfort Professor will be my first and only call."

"Milltown was exceptionally responsive (before, during and after) the work was performed. Across the Milltown organization, they were responsive to my questions about water heater selection; Mike was responsive and a partner in selecting the best location for the new unit and after, Milltown and Mike were immediately responsive when part of the unit was not operating as expected. Milltown is a solid organization that takes pride in their work."

"I couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

"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"
