Understand how your home actually performs. Real data, real answers — not guesses.
Serving Richmond, Midlothian, Henrico, Chesterfield & surrounding areas
Most HVAC companies guess. They look at your home's square footage, make assumptions, and hope for the best. That's not how DNA Heating & Cooling works.
We test. We measure. We verify. Our energy audits and diagnostic testing give you real data about how your home performs — where you're losing energy, where comfort issues come from, and what improvements will actually make a difference.
Whether you're troubleshooting high energy bills, planning a system upgrade, or just want to understand your home better, testing gives you the answers you need to make smart decisions.
Our testing services are valuable for homeowners in several situations:
If your bills seem too high for your home size or usage, testing can identify where energy is being wasted — leaky ducts, air infiltration, or equipment issues.
Rooms that are always too hot or too cold, drafts, or humidity issues often have root causes that only testing can reveal.
Planning to replace your system or add insulation? Testing tells you what your home actually needs so you don't over-spend or under-solve the problem. Learn more about system upgrades.
We offer several diagnostic tests that measure different aspects of your home's performance:
How airtight your home is — the total amount of air leakage through walls, ceilings, floors, windows, doors, and other openings.
We install a calibrated fan in an exterior doorway and depressurize your home. This exaggerates air leaks so we can measure total leakage and identify problem areas.
How much conditioned air your duct system loses before it reaches your living spaces.
We pressurize your duct system and measure how much air escapes through leaks, gaps, and disconnections. This tells us the percentage of air being lost.
Overall home performance — combining testing, inspection, and analysis to give you a complete picture of your home's energy use and comfort issues.
We perform blower door testing, duct leakage testing, thermal imaging, combustion safety analysis, and a detailed inspection of your HVAC system, insulation, and building envelope.
Testing isn't just a report we hand you. We use the results to design better solutions — properly sized equipment, targeted duct improvements, and fixes that address root causes.
Our team understands how homes perform as systems. We don't just run tests — we interpret the results and explain what they mean for your specific situation.
Testing gives you information. What you do with it is up to you. We'll make recommendations, but there's no obligation to move forward with any work.
