What the price includes
An audit covers a look at your home and a report on where you lose energy and what to fix. Higher levels add tests. Fixr lists a blower door test at $150 to $450, duct testing at $50 to $200, and infrared imaging at $300 to $500 as add ons. A HERS rating test costs extra too, at $375 on average, says Bob Vila. It does not include tax or extras the provider adds on the day.
Who charges this and how it is billed
Energy audits are sold by home energy raters, building performance firms, and some utility partners. Most bill a flat fee, and the fee depends on the audit level and the size of the home. Fixr lists $0.08 to $0.50 per square foot. Extra tests such as a blower door test or a HERS rating are billed as add ons, and Bob Vila lists a HERS test at an average of $375. Ask for a written scope and a sample report before you book, so you know what you will get.
When you need this
An audit helps if your power bills are high, some rooms are too hot or too cold, or you feel drafts. It also helps before you buy new windows or insulation, so you spend on the right fix. Many people get one when they buy an older home. The report shows where air leaks and heat loss are the worst.
How to judge your quote
- Ask which audit level the quote covers.
- Ask if a blower door test and thermal imaging are in the price.
- Ask for a written report with fixes ranked by cost and savings.
- Ask if the auditor is certified and carries insurance.
- Compare the total with the range above: $145 to $700 per audit for most people in 2026.
Ways to pay less
- Ask your electric or gas utility first. Some run audit programs, and one call can show whether you qualify for a lower price.
- Pick the level you need. Bob Vila lists a Level 1 audit at $150 to $200, far below the $650 to $900 for Level 3.
- Skip add ons you do not need. Fixr lists a blower door test at $150 to $450 and infrared imaging at $300 to $500, so pick one.
- Get two quotes. Prices vary by city, with Bob Vila listing $300 in San Francisco and $800 in New York.
- Use the report. Fixr says you can save 5 to 30 percent on your yearly energy costs if you make all the suggested changes.
