"Did a great job but then told me he had to clean it much more than he originally planned and added another $25. Their office told me it would cost $250 which is already quite high when I usually pay $200 max. Then he wanted to service my water heater with an annual flush for hundreds of dollars. I have never had one for the past 7 years since the water isn't hard and I don't expect to need one for the next 7 years."

"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+++"

"I am a new homeowner that was looking to complete a few projects around my new home but wasn't sure where to get started. I recently had a heat pump installed and integrated to my existing oil furnace by Blue Bear. The Blue Bear project manager helped explained the difference between fully electric heat pump systems and dual fuel heat pump systems, both options were Mass Save eligible so I would be able to benefit from an instant rebates and not have the hassle of filing rebate applications! Blue Bear took care of it all! We chose a dual fuel heat pump system and the installation looks great! I look forward to saving on oil consumption this fall/winter! Everything went well with our HVAC install and now Blue Bear will be installing a whole home well water water filtration system in my home! We look forward to getting rid of the water staining in our toilets and showers! The Blue Care maintenance plan was a no brainer to sign up for! I highly recommend Blue Bear! 5 out of 5!"
