JP Dunn Heating & Cooling describes itself on its BBB page as an HVAC installation and repair company working on gas, oil, heat pump and forced air systems. Its website lists a service area that includes Northfield, Litchfield, Bristol, Naugatuck and New Hartford, and the company says it has been in business 20 years. A family without hot water said the company answered after hours in the evening, had a technician out immediately, and had the issue fixed less than an hour from the first call. A recent customer said James managed the replacement of a failed mini split system, from removal to installation of the new equipment. Another job went to James Dunn JR and Joe, who a recent customer said installed a new boiler and left the boiler area and hallway clean. A recent customer said their oil delivery guy recommended J.P. Dunn to replace their 60-year-old Granby oil storage tank. In a 2026 review, a customer of 14 years said James came out within the hour after hours, replaced a part, updated the thermostat and bled the pipes, and they had heat within an hour. A 2025 customer said the company fixed a leak on a toe kick heater, piped it in copper and re-wired it, after a two-week wait. A 2023 customer said a tech found the exhaust pipe disintegrated during a furnace cleaning and replaced it within an hour. A 2016 local news article named J.P. Dunn of Northfield as Omni Energy's partner for full service on oil heaters. A recent customer who took the day off said the appointment was cancelled 10 minutes after the planned arrival time due to the rain. A 2025 customer said three calls did not fix their air conditioning and that another HVAC company fixed it the same day. A 2022 customer said they were billed for boiler parts and services that a second company found were not done, and that the dispute ran for four months. Connecticut lists its S1 heating and cooling contractor licence, HTG.0388506-S1, as active, held by J P Dunn Heating & Cooling.
“JP Dunn out of northfield .. they don’t cover the entire state unfortunately but quite a bit.”
“Omni Energy also provides full service for oil heaters with partner J.P. Dunn of Northfield.”
I had a failed mini split system that had to be replaced. James and team came in and managed the entire project, removal to installation of the new equipment. The design and placement of the equipment is almost invisible on the house, unlike our old equipment which was an absolute eyesore. They were all friendly, professional, and very clean coming in and out of the house. I highly recommend this company!
So far not great. I’ll post a follow up after they show up. Booked this appointment weeks ago. Took the day off. Cancelled 10 minutes after planned arrival time due to the “rain”. Were not flexible with rescheduling day.
This company is awesome. I will recommend them always. Lisa is always helping me out trying to figure everything out and what works best for us. They guys that have come to do the replacements and repairs are always very respectful and down to earth. I've never had any issues with them at all and my dogs don't bark at them eithier. Thank you for making our first home warmer literally and for the new tank installation and hot water. I will recommend this family company to anyone and everyone...Y and A🤗
Our Granby oil storage tank was 60 years old and looking extremely dicey. Having lived through the nightmare of a leaking oil tank at a previous residence, I wasn't about to go through that experience again. I asked my oil delivery guy to recommend someone to replace the tank, and he unhesitatingly told me to use J.P. Dunn. That was great advice. I was quoted a very fair price for a new Roth oil tank, and they scheduled a time for the installation that was convenient for me and not way off in the future. The technicians (Carl and Joe) arrived on the designated date, looked the situation over, discussed everything with me, and got to work. Both of them were friendly and professional, and did a fantastic job from beginning to end. I truly couldn't be happier with the completed installation. I highly recommend using J.P. Dunn for your heating and cooling needs.
We lost hot water unexpectedly and needed help fast. No hot water isn’t necessarily always an emergency so to speak but when you’re without hot water with an 11 week old baby and a 2 year old, it complicates things A LOT. JP Dunn answered right away (in the evening after hours), prioritized our emergency, and had a technician out immediately. From start to finish, the experience was excellent. From the initial phone call to having the issue fixed was less than an hour!! AJ was amazing! He clearly explained the issue, walked us through our options, and got everything repaired on the spot. You can tell they take pride in their work and genuinely care about their customers. In a situation that could have been stressful, they made it easy. We’re so grateful and will absolutely be using them again in the future! Thank you guys so much!
