  When I call them because my basement was quickly flooding over a busted boiler, they were here just minutes after I hung up the phone then fixed the problem in no time... Best customer service ever !!!

  Really great service!  Charter Oak went out of their way to make sure I was happy.  When I had an issue with my boiler, they showed up fast. They diagnosed and fixed it immediately.

  Everyone at Charter Oak Mechanical is fantastic!  We can call and know that they'll be there for us anytime.  Julie, the Kevin's, Steven - everyone is great.  Pricing is truly fair - we don't even go out for other quotes.  You will forever have our business.  We love that you are local, in our community and a small business - not some global organization where we would get lost in the shuffle.  Thank you for all that you do to keep us warm in the winter and cool in the summer.

  These guys are real good.  Every year we have them come and check the AC system and they help us to keep it in tip top shape.

  Charter Oak Mechanical LLC excelled at customer service yet again. After business hours, I had an issue with the furnace that led to water leakage. The lady who was on support for emergency repairs was courteous, made note of all the details and promptly called in the technician Eric S, for assistance.
Eric S was punctual, professional, courteous, thorough in his assessment and documentation of the issue and helped remedy the root cause. There was water pooled around the area and he cleaned that up as well.
I would recommend Eric S and Charter Oak Mechanical for your heating, cooling and ventilation services.

  I was very impressed by Charter Oak Mechanical. We just moved into our house in Glastonbury and wanted to install a ducted A/C system before the summer. We solicited a few quotes, and Steve was the first to submit an estimate which was very reasonable given the scope of the work. He committed to begin work within only a few weeks.

Robbie and his team were prompt and professional during the installation process. They were always willing to answer questions and were very accommodating of our needs. The work was completed earlier than anticipated, and it was clearly of high quality. I was also impressed with the subcontractors used, especially Angelo who did a fantastic job boxing in the closet ducts.

I highly recommend Charter Oak for A/C installation.
