Integrity Heating & Air Conditioning, Inc. was established in 1998. We began installing high efficient heating & air conditioning systems and after many years in business, Integrity wanted to help their customers save even more. Integrity has created a long history of educating customers, homeowners & business owners about the huge loss of energy that can take place in various areas of their home and businesses. With that, Integrity has now incorporated Solar into the list of services & products offered by Integrity. Darrin began working in Solar in 1984 while residing in Hawaii during one of solar's peak seasons for approximately 3 years. He has always been very interested in alternative resources. As the climate changes in many aspects environment, economy, increasing costs of utility rates, Integrity continues to help their customers be as efficient & as comfortable as they can.

"This is the second time we have had Integrity do work for us. They have lived up to their name both times The men who installed our system were knowledgeable in what they were doing. They were hard working, personable and polite. Integrity provides both quality equipment and service. When the job was finished everything was cleaned up; the new equipment well explained and we were ready to go. The estimator knew exactly what he was doing and did not try to oversell us on anything. We are well pleased with Integrity and will use their services again!"

"I had a very positive experience with NRG during the sales process: the people I spoke to were knowledgeable, easy to talk to, and quick to follow up with answers to my questions. That changed as soon as we signed the contract and paid our deposit. Communication became sporadic at best, with each step of the process taking much longer--in some cases many months longer--than what I was told during the sales process. To be fair, there were external factors that contributed to the delays. Our project involves installing new roofing, and apparently several roofing contractors are still backed up after the winter storms in early 2023. But that doesn't explain or excuse the near-total lack of communication or the apparent lack of interest in moving our project forward. It has consistently been a struggle to get even the most basic details from NRG, and I've had to follow up every few weeks just to see if anyone is still working on our project. I can't speak to the quality of their work because no work has been done, or even scheduled, more than seven months after signing. I strongly recommend against working with NRG."

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.
