"I couldn't say enough good about Wise and their folks - they replaced my furnace and hot water heater, as well as did all the insulation in my basement, walls and attic entrance. The staff was knowledgeable, friendly, professional, respectful and left my home spotless. Seriously, I've never had as positive experience as I did with these folks. I *highly* recommend them!"

"Michelle was great. Very detail oriented, knowledge, and gave great suggestions during the post-purchase inspection. She allowed us to accompany her during the inspection and answered any and all questions we had, very approachable. She spent almost two hours with us and gave a great, 22 page report with photos afterwards. Good communication pre and post inspection. Highly recommend, I have already sent her info to a friend who is looking for an inspection."

Energy Efficiency Auditing FAQs, answered by experts

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

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.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

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.
