Blue Bear Plumbing, Heating & Air is proud to be the premier provider of air conditioning, heating, and plumbing solutions for South Shore and MetroWest residents. We take pride in meeting our community’s home service needs and delivering unbeatable customer service. With same-day service and 24/7 emergency repair availability, you can rely on us whenever you need fast and effective service!
"As a property manager, we contacted a local company to look at a furnace over a minor leak. I received a phone call from somebody who is wishy-washy, unprofessional, and caused me to treat the call with extra caution. After realizing he had no intention to look at the problem that was called about, I was explained that the heat exchanger was starting to have issues, causing carbon monoxide. When I asked, why doesnâ t the detectors catch it and he said Sometimes it doesnâ t and sometimes itâ s not bad enough yet. So I asked him is there a problem or something that you believe is coming and I could not get a straight answer. He threatened to shut the heating system off Safety concerns. To shut the heat off on my tenant on a cold day. My big issue is how they went about this, instead of shutting the gas off or possibly the breaker, I learned later in the day that they cut wiring inside of furnace. Which I promptly had repaired. And I had the heating system taken apart to confirm or deny whether the heat exchanger Had a crack in it or not. Come to find out everything is fine, all done, by a licensed HVAC person. After discussing this with other people, I have found that this company is prone to pressureTactics, threats and scams. Stay away from Blue Bear of Pembroke!! If you have any questions, you can leave a comment here or you can find me on social. Iâ ll be happy to walk you through why you should not hire or call this company."
