"We had two technicians out over two days. One was for a repair, Daniel. He did a fantastic job troubleshooting and explaining throughout the repair process. As a retired VP of Services, I notice the details and process. They delivered. Louis was sent for a follow-up to service because our fan motor unit needed to be cleaned. All of this was very well documented with pictures and showing me the actual motor unit. Louis did a great job of explaining and showing me the actions and results. It was a service text book delivery of services. Really good... Plus, both technicians worked to save me money with discounts and customer loyalty savings. Fantastic... An honest group of technicians and a company that promotes that in the customers best interest."

"During the hottest part of the summer this year our outside A/C unit stopped working. We had another 3-4 days of 90+ weather in the forecast. We called 3 different companies and no one was able to come out for at least a week.Finally, we did what we should have done first. We called TRG and they came out the next day and quickly diagnosed the issue. They were very straight forward with their assessment and gave us some hard truths that we needed to hear. TRG gave us our options, and within 48 hours we had cold air pumping through our home. After having our options carefully explained to us, we opted to replace our entire A/C unit inside and outside. In the long run, we know that we made the best decision because TRG explained the savings that would occur with the choice that we made. TRG’s technicians and engineers were very thorough and they provided us with all the information and details that we needed to know for us to get the most out of our new A/C system. Our heating unit has got some years behind it, but we are not worried because TRG will come through once again.

Energy efficiency auditing services FAQs

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.
