Jon was very courteous and explained the options during the order so I was satisfied with my choice. Jim did a very competent job in the installation, working well with our property manager to insure the installation looked right on the outside of the building, and even working in the rain to complete the connections to condenser. Jim also patiently explained the system’s operation to me. The units have functioned smoothly since the installation, 4 months now, and the system works well in my home.

Outstanding attention to detail. Neat, competent technicians who were meticulous in their work practices and excellent in the results achieved. My wife frequently comments that the heater installation is more like a piece of art than mere plumbing. Very satisfied with this second installation in 13 years – both perfect.

We love our heat pump! The technician who installed our unit, Jim Brissette, was efficient, knowledgeable and personable. Overall it was a very positive experience. Here it is toward the end of December, and we are still using the heat pump for the main part of our house.

Dunklee is always quick to respond to a problem. I have bought 6 air conditioning units, two furnaces and 2 tank-less hot water heaters between 3 houses over the last 20 years.

I couldn’t be happier. Their service only buys piece of mind.

I have to say I was very cautious when choosing a company to help us replace a destroyed ductless cooling system in our home. Cautious because of my previous experiences with companies I’ve chosen that really did a horrible job.

But, after getting three quotes I chose Duncklee because quite honestly, it just felt right and the price was right. John and everyone were very down to earth and honest. The technicians were very professional and knowledgeable.

I wasn’t surprised to read that John Duncklee was named employer of the year 2012 by the greater Mystic chamber of commerce; he deserves that kind of recognition.

I will be a forever customer of Duncklee Cooling and Heating… Thank you so much!

Obtained necessary technical guidance for HVAC replacement given constraints for my particular condo setup, provided with an overview of considerations, necessary timelines that were respected during the project.

John Duncklee listened to my needs and design a system to convert my newly purchased house to Propane. His technician installed a propane central air heater, on demand hot water heater, propane stove, and propane dryer. All the employees were very courteous and professional. I plan on having a back up generator and barbecue install by Duncklee Inc. this year. I would strongly recommend Dunklee Inc. I found that their prices were competitive and all systems were very efficient. I used less than 300 gallons of propane for the entire year, my house is solar. John, my sincere Thank You

I would like to thank … Duncklee, Inc. for the great job during the installation of two new heating and air conditioning units at the Council of Governments office in Norwich. The project was accomplished when promises, the work site cleaned up at the end of each day, and the crew assigned to the job was most considerate in seeing to it that one of the old AC units remained on while the new one was being installed.

Your installers, I must say, were excellent. They were very professional and considerate of our home. It was a pleasure letting them into the house to work away on the system. They were all business in getting the job done and quite quickly, I might add.

I wanted to take this opportunity to thank you and your staff for the fine installation of our heating and cooling systems… From our beginning consultation to the final installation of the central air conditioning system, the process has been seamless from beginning to end…. each day, during the installation process, the staff was considerate of the building’s interior and extremely careful not to disturb antique furnishings. Special attention was given to making sure our home was in order after each days work shift and clear of any debris before the installers called it a day.

I would be very happy to recommend your services to other home owners looking to improve the value of their personal investments.

I wanted to drop a letter of appreciation and satisfaction with your fine crew during the recent installation of my air conditioning and filtration systems.

Your company was originally recommended by one of my co-workers who stated that your firm was the best one around. Your personal professionalism and that of the installation crew lived up to these accolades.

You may feel free to use us as a member of your satisfied customers! We will certainly recommend Duncklee to out other neighbors and colleagues.
