"Comfort Ductwork replaced my gas boiler. The price was reasonable and the work was impeccable. When they left, the area where they worked was spotless. I wouldn't hesitate to use them for my heating and air conditioning needs in the future."

"We had a heat pump system installed. Eric promised and delivered. Every step of the process was fully explained. Eric took the time to explain the whole system and how it works. His crew were courteous and worked efficiently. I would definitely hire them again ."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"You will not be disappointed with Kyle and company. Replaced old AC unit with a new AC/heat pump system. After the deposit Kyle didn't ask for any money until the job was DONE! AND...while other companies jacked up the price for a heat pump system, Kyle was on the nose. You won't be disappointed at all!!!!"

"The installation of a new split unit Air conditioner unit was done by Joe. He installed the unit, ran the electrical work to my panel, installed all the lines needed. Joe completed the project with the expertise needed and was sure to address all the indoor and outdoor cosmetic piping and ductwork with a great appearance to meet my expectations. Joe was on time, very attentive to all my questions, emails and text messages and the price was very reasonable. I highly recommend using Joe for your AC unit installation and I will be calling him again for any future projects that I may have! 😊"
