I am currently researching heat pumps and actively reviewing companies, their services and quotes. Darren E. from Dunn Heating was professional, highly informative, and was able to explain my options and how they would be of benefit and which choices in my situation would be optimal. Darren was sincere and helpful. I never felt pressured, only heard. Going forward I would trust Dunn heating for both their product warranty and service. Something I can’t say about other companies through direct past experience.

Very efficient and takes time to explain the details of what was found and corrected. Dave also installed our new AC unit a few yrs ago, never had any issues with it.

Alex, NFansu, and Gagan were so professional when they installed our new A/C system yesterday. The worked as efficiently and quietly as they could. All were friendly and courteous too. I especially appreciated how Alex carefully explained what they would be doing before, and then summarized after. He was really patient with all of my questions. We have been loyal customers for over 10 yrs, and will continue to use them. What a great Team!

From top to bottom, the folks at Dunn did a magnificent job outfitting me with a new furnace. Henrik was able to revive my old one long enough to keep me from freezing (important!); Josh explained my options very clearly, giving me great advice about the best long-term solution for my home, and answering my questions with friendly enthusiasm; Tanner and Alai were willing to come to my place early on a Saturday, and thanks to their hard work the new furnace was up and running in less than 3 hours. The whole team was excellent--professional, courteous, skilled--and the price was very competitive. Dunn's the one!

Converted from a tank water heater to a tankless model. Dunn was easy to work with and the install went really well. The old tank was taken away and work site was neat and tidy.
Thanks to Tanner and Alai for their work, and thanks to Darren for his quick response to my request for a quote.
Dunn has an excellent team.

Dave B, the repair technician, has a wealth of knowledge and was able to complete the repair. I've never needed a repair on my furnace or air conditioning system (10 years old now) so I was exploring building a relationship with a reputable local company. So far, they have met my expectations and beyond.

Dunn Heating came back on Friday to clean my ducts after my furnace and heat pump install a few months ago. Luis, Alai and Dale were on time, efficient and quick. They did a very thorough cleaning - the before and after pictures made me glad I had them back!

I just had a new York furnace and heat pump installed by Dunn Heating. Alex and his crew did a great job on the install! They installed the heat pump off my deck (where the AC had been) and into a much better spot beside my house and the thermostat to a far more convenient location. The whole team was very professional and cleaned up thoroughly after getting things set up and tested. I would highly recommend Dunn Heating and Air Conditioning.

We had no power to our furnace and a/c. Called Dunn around 1:00pm and they sent a service tech by 3:30pm - same day. Dave B was respectful of our home, knew exactly how to troubleshoot the problem and solve our issue. Very impressive service on a holiday long weekend. Thanks to Dave B and the Dunn team.
