T.F. O'Brien Cooling & Heating

We had a gas-to-electric boiler conversion completed by the Team at T.F. O'brien with the installation of two 138k BTU units, and the experience was outstanding from start to finish. The service team did a wonderful job—professional, knowledgeable, and efficient throughout the entire process. They clearly communicated progress at every step and made sure everything was fully tested and working perfectly before they left. The whole experience was smooth and stress-free. I would definitely recommend them to anyone looking for reliable, high-quality service for all their heating and cooling needs.

We had a wonderful experience with T.F. O’Brien for our oil-to-gas conversion and mini-split installation. From start to finish, the entire team was incredibly professional, respectful, and kind. The crews were very mindful of our space, kept the work area neat and clean, and caused minimal damage to the walls. Everyone we interacted with was genuinely sweet and pleasant, which made a big project feel much less stressful. The pricing was very fair for the amount of work completed and the level of professionalism provided. Brendan, our salesperson, truly stood out; working with him felt like working with family. He took great care of us, was always accommodating of our schedule, and made sure we felt supported throughout the process. Communication between Brendan and the crews was excell

Had a plumbing emergency at my mom’s house in freezing weather and T.F. O’Brien responded right away. Same-day service, great communication, and they came back the next day to double-check everything. Super grateful for how quickly and efficiently they handled it! So trustworthy, reliable, responsive!

Their free estimate quote was not the cheapest, but it was very reasonable. I would definitely consider wroking with TFObrien for my heating needs at home. I would rate it a 5 stars, nothing is wrong with the quote and they show you how much things are..etc. No BS.

I recently had a brand‑new 140 kBTU Burnham hydronic boiler installed by T.F. O’Brien, and the experience was nothing short of exceptional.
From the first call making the appointment, to meeting Chris Oak (Salesman) impressed us with his professionalism and genuine willingness to listen. He walked us through several options, clearly explaining the pros and cons of each system.

Chris’s courteous demeanor and transparent communication made the whole decision process smooth and stress‑free. The installation crew of Anthony, Angel, and Nick were equally outstanding. They arrived on time and treated our h
