DNA Heating and Cooling

DNA Heating and Cooling operates as a boutique, owner-operated HVAC contractor based at 9831 Kingman Road in Richmond, Virginia. Founded by husband-and-wife team Derek and Laura Aarstad, the company holds a Class A contractor license (#2705187056) and has built its reputation through master-level diagnostics and meticulous installations. The company maintains a perfect 5-star rating across 303 verified client reviews, serving residential customers throughout Richmond, Midlothian, Henrico, and Chesterfield. Operating Monday through Friday from 8 AM to 5 PM, the company focuses exclusively on all-electric heating and cooling solutions, avoiding gas furnaces entirely.

What distinguishes DNA Heating and Cooling from larger regional contractors is their commitment to verified performance. Every installation includes airflow measurement, pressure testing, and duct leakage analysis, practices most companies skip. Their 4% duct leakage guarantee and Lifetime Craftsmanship Warranty set a measurable standard. The company specializes in heat pump installations, duct replacement, and comprehensive energy audits. Derek personally oversees each project as master contractor, ensuring consistent craftsmanship without rotating crews or subcontracted labor.

Customer reviews highlight specific scenarios where DNA exceeded expectations. During the 2026 winter storm, a first-time homeowner in Richmond contacted DNA after their heat failed, and Derek arrived the following day to diagnose and repair the issue at reasonable cost, avoiding the high-pressure upselling common with other contractors. K Nguyen described a same-day emergency appointment after a snowstorm damaged their heating system, with Derek providing prompt professional service and keeping the homeowner informed via text updates throughout.
