  • My husband and I just had a Carrier Furnace installed today and the five young men who worked on the installation were fabulous. They were here early and took their time with the installation, left my basement cleaner than when they came, and were very thorough in their explanation of every detail regarding the use and care of our new furnace. Joel, Donnie, Kurt, Joe P and Joe T, did a fabulous job!!! I would not hesitate to ask to have any of these young men come and work on house in the future. We would highly recommend Dipietro and their workman for any heating or cooling job!

  • “Russell came to look over my very problematic heating situation: an uninsulatable cinderblock house with hot water baseboard heat from a chronically malfunctioning boiler that I wanted to just get rid of He was both professional and personable, figuring out what I did and did not want, or need,and I went with the ductless mini splits, using the Mass Saves Program.

    The DiPietro crew, Daniel and Tom, and Joe Dipietro himself, when needed, did a great job under difficult circumstances, including drilling through concrete! They were careful, polite, hard-working, uncomplaining, and cleaned up after themselves and the work. And Russell helped with the extensive paperwork that rebates and loans require.”

  • Realizing it was time to consider upgrading our nearly 20 yr old inefficient heating and cooling system the task of choosing the right company and product seemed daunting. After reviewing our options it was clear that "DiPietro Heating &Cooling was the choice hands down and we could not be happier with our decision.

    From the initial no cost consultation which included an analysis of our existing equipment and then sitting down at our kitchen table to review all of our options just simplified the process. Their expert recommendations and knowledge of available rebates from multiple sources allowed for a simple and educated decision.
    All facets of the job from beginning to end to complete the installation were well planned and orchestrated and the installation team was very impressive. Additionally, the office staff was extremely helpful assisting with multiple rebates in excess of $2,000.00.

    We have been much warmer this winter and cooler this summer yet our utility bills have decreased significantly. We are confident that we absolutely made the right decision and would encourage anyone else to do the same. Simply " Call DiPietro." we are very glad we did.

  • DiPietro installed a new hot water heater, cleaned the furnace and fixed a faucet and toilet for me. They were prompt and clean. Matt was helpful and informative. Their receptionist is also great. I would highly recommend them.
