DNA Heating & Cooling

DNA Heating & Cooling serves the Greenbrier, Tennessee community as a residential HVAC contractor holding a 4.0-star average rating across four customer reviews. Available around the clock seven days each week, the team handles heating and cooling equipment needs for homeowners throughout the region.

Dewayne, the primary technician at DNA Heating & Cooling, differentiates this contractor through a hands-on approach that reviewers describe as refreshingly non-pushy. One customer noted receiving a same-day price estimate and multiple follow-up visits to optimize system settings after installation completion. This commitment to ensuring proper configuration sets the business apart from contractors who complete work without confirming long-term performance.

A reviewer named Lakreshia detailed her experience calling Dewayne when her aging unit required replacement. She collected bids from two competing companies before selecting DNA Heating & Cooling based on the combination of competitive pricing and thorough explanation of the replacement process. Dewayne arrived for an estimate the same day and returned several days post-installation to verify optimal thermostat calibration.
