Finally, I'm a proud owner of American Standard central air conditioning system installed by great team of people led by Jeremy! They did an excellent job overall and left the place spotless. Showed up on time and started working right away and did an awesome job installing and hiding the pipes and replacing the wires. They listened to my suggestions and answered all my questions. I would recommend them any day, anywhere. Thank you!

I had tried a DIY installation of a Third Generation Nest. There was an issue with the electric hookup of the thermostat in my house. I put in a work request for a Third Generation Nest installation for my home. Kevin from Charter Oak Mechanical was quick to respond and very helpful. He was able to identify the issue and solution the installation of my Third Generation Nest. He was pleasant, knowledgeable and quick to complete the work request. He even assisted in the initial program setup for the Nest.

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value If you are in need of an HVAC company in the Hartford that knows what they are doing, this is the company you are looking for. I recently had them come out to address a problem we were having with our smart thermostat which was in need of extra wiring to avoid a slow battery drain. I had already called the "pros" per the manufacturer's website to look at it and they simply threw their hands up and concluded it was a compatibility issue....but, it just didn't smell right to me. Had Charter Oak stop in for a second opinion, and wouldn't you know it, I had been misled and they knew exactly how to fix it and proved that the so called "pros" weren't the experts as advertised. Not only that, but, they really educated me about our system in our new home that we've only been in for a year. I will definitely be calling up Charter Oak for my future HVAC needs and I recommend you do the same.

We recently replaced our 40 year old gas boiler with a Bosch high efficiency boiler. The new boiler comes with a tankless water heater so we no longer need a separate water heater. We have been so thrilled with your service, from the office manager Sarah to the salesman to the installation crew. Due to the structure limitation of our house, the new boiler could not vent through the wall, which would have been a much simpler installation. It needs to vent through the chimney via a specially designed concentric flue. During the installation process, the team led by Jeremy encountered some unforeseen obstacles. Jeremy and his team's 'can do' attitude resolved each and every road block, and the mission was accomplished flawlessly. The technicians are courteous, pleasant, punctual, organized and professional. Being a perfectionist myself, I am extremely impressed by their work ethic. Their knowledge and superb workmanship led to the awesome end result. Thank you Charter Oak.
