Energy Audits near you

The visit has a shape, and knowing it lets you tell a real audit from a sales call. DOE's Weatherization Assistance Program describes the audit it uses as a computerized assessment of the home's energy use that involves an analysis of energy bills and a blower-door test, with an inspection of all areas of the home for potential improvements and for health and safety issues, after which the auditor provides recommendations, and, once work is complete, an inspector verifies that it meets specifications.

The measurement sequence follows the same logic as any retrofit. The house is depressurized with a calibrated blower door so total envelope leakage can be quantified, duct leakage is measured separately with a duct pressurization test, infrared imaging is used while the house is under pressure so that leaks and missing insulation show up as temperature differences, and the combustion appliances are tested, including draft pressure testing with a combustion analyzer.

The deliverable matters as much as the visit. An audit that ends in a verbal summary and a quote has given you nothing to compare, nothing to re-test against and nothing to take to a second contractor. Ask before booking what the written report will contain and whether the raw test numbers will be in it.

There is no federal license for home energy auditors, but there is a federal list, and it is the most useful credential check available. For the purposes of the Energy Efficient Home Improvement Credit, the Department of Energy published the qualified certification programs an auditor must hold, and the IRS in turn defines a qualified home energy auditor as an individual certified by one of those programs at the time of the audit, or someone working under the supervision of such an auditor.

The programs DOE lists include the Building Performance Institute's Building Analyst Professional and its Home Energy Professional Energy Auditor, the Residential Energy Services Network's Home Energy Rater, ASHRAE's Building Energy Assessment Professional, the Association of Energy Engineers' Certified Energy Auditor and Certified Energy Manager, several Building Science Institute credentials, the Energy Management Association's Energy Management Professional, and the California programs CalCERTS Whole House Home Energy Audit and CHEERS HERS Rater.

Even where a tax credit is not in play, that list is a reasonable shortlist for anyone hiring. Ask which certification the person arriving at your door holds, ask whether they are the certified individual or working under supervision, and check the credential with the issuing body rather than accepting a logo. Any state or local licensing that applies to contracting work is separate, and still applies.

The Energy Efficient Home Improvement Credit under section 25C included home energy audits, and the requirements it imposed are a good specification for an audit even now. The IRS states that a home energy audit for your main home may qualify for a credit of up to 150 dollars, and that the audit must include a written report and inspection that identifies the most significant and cost-effective energy efficiency improvements, with an estimate of the energy and cost savings for each such improvement.

The report also had to be traceable to a person. The IRS requires it to be prepared and signed by a qualified home energy auditor, to be consistent with industry best practices, and to include the auditor's name and relevant employer identification number or other taxpayer identifying number, an attestation that the auditor is certified by a qualified certification program, and the name of that program.

The timing is the part to verify rather than assume. The IRS page for the credit states that you can claim the credit for improvements made through December 31, 2025, and the Department of Energy notes that the One Big Beautiful Bill Act, enacted on July 4, 2025, revised dates and provisions in the Internal Revenue Code affecting some or all of these credits, directing readers to the IRS for current details. Check the IRS page yourself before relying on any tax treatment, and treat anything you read elsewhere that assumes the credit is open as out of date until the IRS page agrees with it.

Many utilities and state programs offer a no-cost or low-cost home energy visit, and they are worth taking. They typically involve a visual survey, some direct-install measures such as lamps and aerators, and a report of recommendations. What they usually do not involve is a blower door, a duct test or a combustion analyzer, and without those the visit cannot tell you how leaky the house is or whether the ducts are the problem.

A diagnostic audit costs money and produces measurements. It is the right purchase when you are about to spend meaningfully on insulation, air sealing, windows or heating equipment, because it tells you which of those will actually change the bill, and it gives you a before number to test against afterwards.

There is a third category to be wary of: the free assessment offered by a company that sells one product. The assessment may be perfectly competent, but it is scoped by what the company sells. If the recommendation from a free visit is always the same measure, that is worth noticing.

Audits vary in price mainly because they vary in depth. What moves the number is the size and complexity of the house, whether duct testing is included alongside the blower door, whether combustion safety testing is part of the visit, whether infrared imaging is included and under what conditions it is done, whether multiple heating or cooling zones have to be assessed separately, whether a formal energy model and savings estimate is produced, and whether a follow-up test after the work is included.

Ask four things before booking: which certification the auditor holds, which tests will be performed, what the written report will contain, and whether a post-work test is available and at what price. The IRS specification for a qualifying audit report is a fair benchmark to hold any auditor to, whatever the tax position: a written report identifying the most significant and cost-effective improvements, with an estimate of the energy and cost savings for each.

LokalMatch connects you with people who do this work. Describe the house once, auditors and contractors serving your area see it, and those interested contact you. Pros pay for the requests and homeowners pay nothing. LokalMatch does not perform audits, does not set prices and does not vet or recommend any company, so verifying certification and insurance is still your step.
