DNA Heating and Cooling

Derek worked some serious magic to install a smart thermostat in my house. He was able to trace the maze of wiring from my thermostat upstairs to my air handling unit in the basement and replaced the wiring to make sure my new thermostat (and any future ones that are installed) will work properly. On top of all the great work he did, he took some extra time to look at other projects I’d like to have done around the house. I can’t wait to work with Derek again the next time I need any HVAC or mechanical work. He is professional, incredibly knowledgeable, great to chat with, and does quality work. Support this locally owned business—you will be glad you did!!

Hands down the most thorough A/C maintenance I have ever had. Derek offered suggestions for efficiency improvements but was not pushy or over dramatic. He took pictures where he cleaned my outside unit which no one has ever even look at since it was installed, as well as my intake duct which is surely a source for my worsening breathing. He provided a trusted resource for duct cleaning and explained why he recommends them. I offer DNA this deserved 5 star review knowing the busier they are the harder it will be to get them out. Totally worth any wait (well, at least now when it’s only in the 70s). I feel confident I have found my new HVAC team.

I had run into an emergency with my HVAC unit not heating my house after a snowstorm. I had called and they were able to schedule a visit to my house the same day. They provided texts keeping us looped when someone was coming. Derek was professional and prompt, getting a fix for our unit the same day. Highly recommended.

6 months into being a homeowner, my heat went out during the 2026 “snowmageddon.” I reached out to DNA on a friends recommendation. Derek came out a day later and made a quick and professional assessment of my problem and was able to fix it at a very reasonable price. DNA was the right choice for me, especially when some other contractors tend to be more “sales” oriented rather than focused on fixing a smaller issue in a normally healthy system. 5 stars

We are so appreciative of the thorough services with DNA Heating & Cooling for our HVAC. We trust that they will take good care of our home without ever overcharging or upselling, and we know we're getting expert-level services. Highly recommend!
