"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Within hours of my inquiry on a Saturday, Bill was out to my house to assess my needs. I needed a new water heater and my AC repaired. I knew I would be looking at a lot of money, because I had other quotes. His price was amazing and the job was completed in less than a week! I would highly recommend this company."

"By the time I found Joe’s business, the water heater had been deemed dead’s by the manufacturer, it was Sunday afternoon, a blizzard was to start around 8:00pm. Joe and his partner took out the old heater, drove with me to HD picked up the new one, installed it and I had hot water before the first snow flakes hit the ground. The price was very reasonable too, regardless of the circumstances. Two thumbs up and five stars."

"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!"

"They installed a new hot water heater for me back in March. Nine months later, a part failed. Although the water heater was under warranty, Burke told me I would have to pay the labor but the manufacturer would reimburse me. The manufacturer refused and Burke Plumbing and Heating stepped and reimbursed the labor fee of $250.00! They are awesome and I would highly recommend them to anyone!"
