Professionalism, Quality, Responsiveness
I'm very happy with the installation of our oil to gas conversion. Matt was extremely diligent in making sure everything was working properly, stayed late, and returned the next day promptly after the installation to resolve a minor issue he identified. Took pride and ownership of his work. I was impressed and would recommend these guys to anyone. The sales experience with Brendan was a good one too. He explained everything thoroughly and made a number of sensible recommendations. No high pressure sales tactics. Accessible and responsive.

We Were Pleasantly Surprised
Last year our central air system went down and were having horrible summer, we ended up calling lots of vendors to come give us quotes. We were pleasantly surprised when one of the owners Chris came himself to evaluate our issues and guiding us on what system we should replace it with. Hence we decided to go with them and we were glad we did. The installer and customer service were beyond friendly and Uber professional. Highly recommended.

I Would Definitely Recommend this Company!
My brother was impressed by their local advertisement. So I called. From the first person to the last person I communicated with, in the company, were kind & warm. Let’s not forget about their expertise & responsiveness. They explained my choices, the cost & the process in a manner I understood without dimming down the info. We ultimately chose to install two new heating units. I would definitely recommend this company!

The Crew was Extremely Professional, and Courteous
I am never at a loss for words, but its hard to describe the work that T.F. O'Brien did at our home. within one day we went from having a boiler from the nineteen sixties to having state of the art equipment, hot water heater and boiler installed.
The crew was extremely professional, and courteous.
Having Tom one of the owners stopping by our home to make sure everything went smooth was a pleasure. And let me not forget Pat truly professionals the way they take care of your every question and needs.
YOU GUYS ARE AWESOME!!

Professional and Informative Service
Was very pleased with the professional and informative service I received while purchasing a Fujitsu ductless AC and heating unit. The installation of the unit was completed by knowledgeable installers. The follow up maintenance service was performed by a qualified technician.

Most Professional, Most Responsive, and Informative
Met with several contractors for a ductless AC installation. T.F. O'brien was the most professional, most responsive, and informative out of all of them. Just felt the most comfortable with them. Very happy with the new unit and highly recommend them for their professionalism, knowledge, and experience.
