Every month you open your energy bill and wince. You’ve tried turning off lights, adjusting the thermostat, even buying new appliances—but the numbers barely budge.
The frustrating truth: you can’t fix what you can’t see. Your home could be leaking energy through dozens of hidden gaps, poor insulation, inefficient equipment, or ductwork problems you don’t even know exist. A professional home energy audit shows you exactly where your money is going and what to do about it.
What Is a Home Energy Audit?
A home energy audit is a comprehensive assessment of how your home uses—and wastes—energy. Think of it as a diagnostic checkup for your house.
A qualified auditor evaluates your insulation, air sealing, HVAC system, ductwork, windows, doors, and appliances. Using specialized equipment, they identify hidden problems and produce a prioritized list of improvements that will actually make a difference.
Types of Energy Audits
DIY walkthrough: Free self-assessment—good starting point, but limited scope.
Utility company audits: Free or low-cost online assessments or basic in-home evaluations. Dominion Energy offers options for Virginia customers.
Professional energy audit: Comprehensive testing using diagnostic equipment.
Comprehensive audit with diagnostics: Includes blower door test, thermal imaging, duct testing, and detailed report. Most thorough option.
What’s Included in a Professional Audit
A comprehensive energy audit typically includes visual inspection of the entire home, review of past energy bills, insulation assessment (attic, walls, floors), air leak detection, HVAC system evaluation, ductwork inspection, window and door assessment, water heating evaluation, and a detailed report with prioritized recommendations.
The Blower Door Test
The blower door test is the cornerstone of professional energy audits. A powerful fan mounted in an exterior doorway depressurizes your home, revealing hidden air leaks that are invisible during normal conditions.
The test measures your home’s overall air tightness and quantifies how much conditioned air you’re losing. Combined with a walk-through inspection, it pinpoints exactly where sealing is needed—gaps around windows, outlets, plumbing penetrations, and the attic-to-living-space connection.
Thermal Imaging
Infrared cameras reveal temperature differences invisible to the naked eye—insulation gaps inside walls, air leaks around windows and outlets, moisture problems affecting efficiency, and hot spots indicating ductwork issues.
When combined with the blower door test, thermal imaging provides dramatic visual evidence of exactly where your energy is escaping.
HVAC System Evaluation
For most homes, heating and cooling account for roughly 50% of energy use. A thorough HVAC evaluation covers equipment age, condition, and efficiency ratings; proper sizing for your home; airflow and temperature testing; ductwork inspection for leaks and damage; and thermostat review.
Ductwork issues are one of the most common problems we find. Leaky or poorly insulated ducts can waste 20-30% of the energy used to heat and cool your home.
Insulation Assessment
Auditors measure existing insulation levels and compare them to current recommendations. For Richmond-area homes, the Department of Energy recommends R-38 to R-60 for attics, R-13 to R-21 for walls, and R-25 to R-30 for floors/crawlspace.
Common problems include insufficient depth, settling over time, gaps from previous work, and moisture damage. Insulation upgrades are often the highest-impact, most cost-effective improvement.
Energy Audit Costs
Audit costs vary based on home size, tests included, and depth of analysis. Basic walk-through assessments cost less than comprehensive audits with blower door testing and thermal imaging.
Ways to reduce costs: Dominion Energy customers may qualify for subsidized assessments; federal tax credit covers 30% of audit cost (up to $150); some contractors credit audit cost toward improvement work.

Are Energy Audits Worth It?
According to the U.S. Department of Energy, implementing audit recommendations can save 5-30% on energy bills, with most homes achieving 15-20% savings. For a household spending $200/month on energy, that’s $360-$720 in annual savings.
Beyond energy savings, audits identify comfort problems (drafts, uneven temperatures), detect safety issues, provide documentation for rebate programs, and give you a prioritized improvement list so you fix the right things first. The audit typically pays for itself within the first year of implementing recommendations.
What Happens After the Audit
Review findings with your auditor, prioritize improvements by impact and budget, explore rebates and incentives, then implement improvements (phased over time if needed). Consider retesting after major improvements to verify results.
Virginia Rebates and Incentives
Dominion Energy programs: Home Energy Assessment program provides personalized reports and may qualify you for rebates on improvements.
Federal tax credits: 30% credit on qualifying energy improvements (heat pumps, insulation, air sealing, efficient HVAC), with annual limits up to $3,200.
Virginia Home Energy Rebates: When launched, may provide significant rebates for efficiency retrofits and high-efficiency appliances for qualifying households.
Check current program availability before starting—requirements and funding change frequently.
The H&H Approach
At H&H, we focus on the HVAC-related factors that most affect your energy efficiency: your heating and cooling equipment, your ductwork, and how they interact with your home’s overall performance.
We evaluate your system honestly—not just looking for equipment to sell, but identifying what’s actually wasting your energy. If insulation or air sealing is your bigger problem, we’ll tell you. Fifty years of experience with Richmond-area homes means we understand the common issues and solutions that work best in our climate.
