"Replaced my water heater in an emergency and went tankless. Super happy with the entire team. They provided me temporary hot water and came back the next day to put on the tankless water heater. They gave me options and I’m happy with going tankless"

"R&B are great! They were able to come out and see the job and give me a price. They came back a week or so later and knocked it out in under 2 hours."

"Metro West Mini Splits recently installed 6 mini splits in February 2025 to our new home in Marlborough, MA. Alan, Jamie, and their team were so kind, respectful, knowledgeable, timely, communicative, and easy to work with. We could not be happier with the final product! Metro West Mini Splits was also very reasonably priced, and they made the Mass Save rebate process a breeze. 100% would recommend to anyone needing heating or cooling services!"

"Shawn Thompson did a great job diagnosing our AC issue and repairing it promptly. He is an above-and-beyond the call of duty kind of guy who came out after hours to help us out during a heat wave. I couldnâ t recommend him more highly."

"The first HVAC contractor (a national chain) I had in to look at my central A/C diagnosed the air handler's fan blowing backwards as a result of a lightning strike scrambling the circuitry. (I told them about the lightning strike in the interest of full disclosure.) This other contractor said it likely needed a new fan but because of the strike they would not repair it. Instead, they would only replace the entire air handler...to the tune of $5700. We were prepared to suffer through the imminent heat wave and fork over the big bucks, but I wanted to get at least one other quote. I had found B&M on HomeAdvisor and requested an appt for a quote. HomeAdvisor wound up canceling the appt because they hadn't heard back from B&M. I decided to call directly. I talked to Paul M and he said they were so busy and couldn't commit to the HomeAdvisor appt time but that they would squeeze me in. I was expecting only a quote, but they didn't give up and wound up fixing it on the spot. It's been working like a champ through the heat wave, and it only cost me $217. Paul even followed up a few days later to ask how it was performing. I highly recommend B&M."
