WHO WE ARE
At DNA Heating & Cooling, we’re not just another HVAC company — we’re Derek and Laura Aarstad, Richmond natives who built this business on integrity, trust, and personalized service. As a husband-and-wife team, we take pride in offering a boutique experience where every client feels like part of our extended family.
Derek is a Master HVAC Contractor with a Class A license, bringing over 15 years of technical expertise, hands-on craftsmanship, and a commitment to continuing education. He ensures every system is serviced with precision, consistency, and care. Laura brings over 15 years of experience in administration, customer service, and management, making sure our operations run smoothly and that every client receives clear communication and outstanding support from start to finish.
We may be a small company, but that’s by design. With DNA Heating & Cooling, you’ll always get personal attention, unmatched quality control, and a level of care you won’t find with larger operations.
That’s the DNA difference.
Meet Derek – Master HVAC Tradesman
When you choose DNA Heating & Cooling, you’re not dealing with a large crew of rotating technicians — you’re working directly with Derek Aarstad, a Master HVAC Contractor with a Class A license and RBEA (Residential Building Energy Analyst) certification. Derek is the only technician who will service your equipment, which means you get unmatched attention to detail, consistency, and quality control on every job.
With over 15 years of hands-on experience, Derek believes in doing things the right way — no shortcuts, no cut corners. Every visit is about building trust and treating your home as if it were his own. That’s the foundation of DNA Heating & Cooling: a boutique HVAC company that’s small, focused, and built on integrity.
Derek is NCI certified and committed to staying ahead of the curve through continuing education and advanced training. His expertise goes beyond traditional heating and cooling. DNA is at the forefront of the electrification movement — spearheading the shift away from combustible fuels to safer, cleaner, and more efficient technologies. That means replacing outdated gas furnaces with high-efficiency heat pumps, and upgrading gas water heaters to modern heat pump water heaters that save energy, reduce emissions, and protect your family’s safety.
With Derek, you’re not just hiring an HVAC technician — you’re gaining a partner who’s dedicated to comfort, efficiency, and the future of home heating and cooling.
