Richmond's Boutique HVAC Company
Derek and Laura Aarstad founded DNA Heating & Cooling with a mission: deliver HVAC that prioritizes safety, efficiency, comfort, and health—not just equipment replacement. As a boutique, owner-operated company serving Richmond, Midlothian, and Henrico, we've built our reputation on doing what larger contractors won't.
We test every system. We size equipment to your home's actual needs. And we're leading the region's shift to all-electric heating and cooling. No gas furnaces. No carbon monoxide. No rotating crews. Just expert service backed by measurable results.
Expert HVAC Services
From all‑electric heat‑pump installations to comprehensive energy audits, we provide high‑performance heating‑and‑cooling solutions throughout Richmond, Midlothian, Henrico, and Chesterfield. Every system tested, measured, and verified.
Heat Pump Installation
Upgrade to a modern heat pump system — efficient heating and cooling from one unit, installed by a Master HVAC Contractor.

Duct Replacement & Sealing
Most duct systems leak 20–30%. We design and install ductwork that performs — verified by testing and backed by our 4% leakage guarantee and Lifetime Craftsmanship Warranty.

Maintenance Plans
Preventative maintenance protects comfort and equipment investment. Our annual tune-ups improve efficiency, prevent breakdowns, and include priority scheduling and repair discounts.

Energy Audits & Testing
If your home has hot/cold spots, high bills, or just doesn't feel right — testing reveals why. We measure how your home actually performs and provide a roadmap to better comfort and efficiency.

Indoor Air Quality
Your HVAC system impacts more than temperature — it affects the air you breathe. We add filtration, humidity control, and ventilation for a cleaner, healthier indoor environment.

Ductless Installation
Ductless mini-splits deliver high-efficiency heating and cooling for additions, remodels, and rooms ducts can't serve. Quiet comfort, zoned control, and no ductwork required.

How We Work (And Why It's Different)
01
Learn Your Home, Not Just the Unit
We start by understanding how your home actually behaves—comfort issues, hot/cold rooms, allergies, utility bills—not just 'what's broken.'
02
Diagnose With Data, Not Assumptions
Most HVAC companies guess. We measure airflow, pressure, duct leakage, equipment performance, and system design. If we can measure it, we do.
03
Engineer the Right Fix
Comfort isn't one-size-fits-all. We design solutions tailored to your home—not oversized box swaps or lowest-bid shortcuts.
04
Install With Accountability
A Master HVAC Contractor oversees every project. High-performance installation built for comfort, efficiency, and reliability — with quality control from start to finish.
05
Prove It Before We Leave
We test and verify system performance, share results with photos, and explain what changed—so you know it's working and why it matters.
