Local family owned air conditioning company with 25+ years of experience. I offer free second opinions on another company’s diagnosis of your system. No overtime charge. Free estimate on equipment change outs. I do air quality testing for your home or business. Dehumidification, solving airflow issues, repair or maintenance, system design, I can do it. Give me a try, I won’t let you down. Chris Rattray @Aire Serv

"Our system was not cooling and we needed it checked for all issues that could be causing it. The technician did incomplete checks and declared the issue was just that the plug was not in place, he did not give us an estimate for approval, he directly billed us to pay $275 for putting the plug in place. After a few days the issue with our cooling reappeared, he came back and mentioned there could be leak but refused to check where the leak was without another payment. When he came the first time he should have at least checked our system properly for the $275 he charged us. They just declared everything is good without even checking with the meter."

My firm helps organizations increase profits by reducing expenses, recovering overcharges, and taking advantage of available tax incentives. We're helping employers reduce the cost of their health benefits, typically by 12 to 25%, and sometimes much more, and without necessarily changing their broker or changing their health plan provider. We don't sell insurance, we address the medical billing issue that drives the costs. We are better than any broker/agent because we build your plan from the ground up, then manage it to keep costs down. We have over a decade of experience saving our customers millions of dollars. We are "zero contingency", which means if we don't find you savings, there is no fee.

"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.
