"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"I had a new electrical line I wanted to run for a display light attached to a grandfather clock in our foyer. I also requested a switch be added to our wall panel by the front door to operate it. The job involved seeking a route for running wire behind the ceiling and drywall from our basement to the first floor of the house. The installation was complicated and obviously required a healthy amount of expertise in all respects. The work was accomplished with a minimal amount of mess (two small holes) and the quad switch panel added by our front door operates flawlessly. During the same visit they also replaced four decorative ceiling light fixtures and repaired a bad electrical outlet to boot. The workers were fast, efficient and friendly (even to my dog). I can't say enough about this company to do this justice. Very satisfied with my decision to give them a call."

FAQs for energy efficiency auditing projects in The Plains, VA

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

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.

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.
