“Our old HVAC system was struggling and we knew we needed to have it replaced. Derek came out next day to take a look at it and gave us our options (tune-up, replace, etc). We decided on a full replacement with new duct work. They were willing to get the unit & ductwork replaced in our crawlspace within 2 days of us talking about it! When the day came for the install, they completed the entire project in just a day. Fantastic work!”

“My AC unit was way over due for a preventative maintenance check so DNA Heating and Cooling came out today to perform an AC Tune Up. Derek was very thorough and knowledgeable, taking time to educate me during the process. I will definitely use him again. Overall great experience. Thank you Derek!”

“HVAC technicians are valuable and sometimes hard to find. I am grateful for Derek and his service was excellent. He will be my goto.”

“I would give DNA 10 stars if I could! Before Derek came for a diagnostic appointment on my attic unit, I had TWO different techs from two different companies come out, because of my home warranty. Neither of the first two techs were able to fix the issue I was having in its entirety, in fact, the very first didn't do more than just look at it. Derek spotted the issues within seconds, and fixed my attic system within a matter of a few hours, while he was already at my home for the diagnostic. I SO appreciated that I didn't have to schedule another appointment. He was knowledgeable, and more than happy to share any and all information. As a single mom on a budget, the cost was also incredibly reasonable. I will NEVER trust anyone other than DNA with my HVAC!”

“We had an outstanding experience with DNA Heating and Cooling. Derek, the owner, is by far the most knowledgeable and thorough HVAC professional I've ever met. He took the time to explain everything in a way I could understand, and it was clear he's focused on helping us for the long term—not just trying to sell something. His analysis and service were far more detailed and comprehensive than what we've experienced with other companies, including Woodfin. Highly recommend!”

“Thank you for coming out to diagnose our ac duct leak. Looking forward to having all that outdated and worn ductwork in the attic replaced.”

“I just had a complete system replacement including all new ductwork throughout. The entire process from the initial consultation to the planning and execution went great. After speaking with Derek about the install I felt at ease about my decision to go with DNA heating and cooling. Derek was honest and up front and I never felt pressured or like he was trying to sell me something. I would not hesitate to recommend DNA Heating and Cooling to anyone who may be in need of there services. It can be difficult to find trustworthy businesses these days, and I am relieved to have found DNA to handle all of my heating and cooling needs. I am certainly a customer for life.”

“Today Derek with DNA came out to help us with what turned out to be a minor repair/adjustment and some education with our mini split HVAC. Just as before Derek did a great job, good communication on appointment time and arrival, quick understanding of concerns and identifying the issue; followed by a full explanation and photos of repair. I really appreciate the service! My largest project to date with DNA was recently completed and I am very pleased with the outcome. Derek and Jeff came to install a mini split system that included one outdoor unit and two indoor room units. I love these mini splits, and they are defiantly the way to go if you have spaces like my basement that are hard to keep comfortable with the standard system. DNA really did a great job with this install both with quality of product and workmanship.”

I can't recommend DNA enough!”

“Had a referral from a well respected colleague and friend to contact this company for a fresh new install for our farm house.i went over my thoughts and concerns and he came up with a game plan for split units one in each room of the house (thank God). Derrick not only took my call long with the very accommodating office manager,came all the way to Amelia to get my install done with a fair price considering the drive to our home. Derrick was on par with making sure how we felt during and after the install, he called checked on us 30 days later to make sure everything was running smooth and as it should and our house was comfy for the kids. Had an issue with one unit for a brief moment he answered at night and called me back immediately and helped me remedy the easy which was just batteries in the remote!! Highly highly recommend DNA HEATING AND COOLING if you don't want to be ripped off, and have quality work done with a decent customer service experience.”

Thank you DNA for giving me a fair price $199 for the year and peace of mind!”
