DNA Heating & Air

DNA Heating & Air has earned a 4.8-star average across 144 reviews in Columbus, Georgia, and the surrounding Fortson area. As a Lennox Network Dealer, this contractor maintains the factory support andparts access that comes with a national brand partnership. Their technicians handle residential and light commercial work across the Chattahoochee Valley, with service trucks rolling out every day of the week on demand.

What separates DNA Heating & Air from independent shops is the Lennox dealer relationship. That connection opens access to factory-direct rebates, extended warranty coverage, and equipment that smaller dealers cannot order. Their website also lists indoor air quality upgrades, duct cleaning, and mini-split system installs alongside conventional gas furnace and central AC work, giving homeowners options beyond the standard replacement job.

Michael Skillern used DNA Heating three separate times over the years, noting that office manager Amy runs communication like a texting service, sending real-time arrival updates so customers never wait in the dark. When an issue flared during Skillern's last call, technician Justin arrived and resolved it the same morning. For Jamarius Wade, the crew completed an entire unit replacement while his family was on vacation, with no homeowner presence required. Both scenarios demonstrate how this company handles large and small jobs without disrupting the household.
