Customer Testimonials

"We highly recommend Duncan Heating and Air!! We called them a little over a month ago to come out and try to fix our nightmare we had been dealing with for 8 years and give us a quote to replace our entire unit along with all duct work and move the unit. From the 1st phone call and service call all the way through the entire installation of our new units they were a pleasure to work with. The 1st thing I noticed was the compassion from Kathy and Cole. We were freezing because our unit once again was not working. They came out the same day to try and get us some heat. This happened 2 more times where the day I called they had someone out there. The whole process was professional and done in a very timely manner. We love our new units!!! We will continue to use them for all of our hvac needs. Thank you all so much!!! Happy New Year!"

"If I could give Duncan Heating and Air Services 10 stars I would. They are the best company to work with. Local, family owned, and very considerate. I needed to have a whole new system put in and they mean what they say when they will take care of you. Thank you I truly appreciate everything you have done. I would highly recommend them."

"Cole Duncan and his team are amazing!! They installed a new unit for me a couple of years ago and complete 2 annual checkups. Not only are they a local family from Dawsonville, they are so pleasant to work with. I know when I call, they have me covered, even on a Friday night! If you need a dependable, honest company to service your heat and air, give them a call. Chav"

"Shout out to Cathy/Cole and team for everything they've done to get our A/C back up an running. Duncan replaced our condensing unit a while back and the quality has been excellent. We now only have to refill our propane tank once a year. Also, they've done an awesome job supporting Athens Boat Club on the facilities here. Highly recommend Duncan HVAC!"

"Absolutely amazing service from Duncan heating and air. Cole and the gentleman he had with him, I completely forgot his name, they got our unit up and running in less than the time he estimated. Very warm and welcoming company. We will be doing business again in the future with them."
