Find Energy Auditors Near You
A professional home energy audit is the smartest first step before any major energy upgrade. Our directory lists certified energy auditors who use blower door tests, infrared thermal imaging, and duct leakage testing to identify exactly where your home is wasting energy — and which improvements will save you the most money.
What an Energy Auditor Does
A certified energy auditor conducts a systematic evaluation of your home’s energy performance. Using diagnostic tools like blower door fans and thermal cameras, they measure air leakage, identify insulation gaps, check duct integrity, evaluate HVAC equipment efficiency, and test combustion appliances for safety. The result is a prioritized report showing which upgrades deliver the best return on investment for your specific home.
A professional audit typically costs $200 to $600, though many utility companies offer free or subsidized assessments. The Inflation Reduction Act also provides a $150 tax credit for qualifying energy audits.
Who Should Get an Energy Audit?
An energy audit is especially valuable if your energy bills are higher than expected for your home’s size, your home was built before 2000 (likely missing modern air sealing and insulation standards), you experience drafts, hot and cold spots, or uneven temperatures, you are planning to install solar panels (reducing usage first means a smaller, cheaper system), or you want to upgrade your HVAC system and need sizing data.
Choosing an Auditor
Look for BPI (Building Performance Institute) certification or RESNET HERS rating qualifications. Ask whether they perform blower door and duct blaster testing (some “audits” are just visual walkthroughs), what their report includes, and whether they are affiliated with any contracting companies that would perform the recommended work (independent auditors tend to give more objective recommendations).
