"From the estimate to job completion everything was professional and on time. LHS left my house as clean as they found it.

I placed a thermometer in my attic and there’s close to a 40 degree difference between before and after the spray foam insulation. Job well done."

"I've been with Posigen for about 7 years now and have always paid my bills on time!!!! As of Feb. 2022, I haven't been able to monitor my Solar Production because Posigen haven't updated their system to 5g Capability!!! I told them my payments are to be deferred until they update the system on their end!!! I spoke with a couple Reps that said your panels are producing what they should based on your production on your Electric Bill!!! I asked how can I know if I cant see the daily production to ensure the panels are producing what they should!!! They said take my word for it!!! I'm like that's very bogus to tell a faithful customer to take your word!!! Especially when the issue is not on their end!!! Now because of Non-Payments for 2 months of me not knowing what I'm producing since Feb, they're now threatening to shut my system off!!! Who treats a customer like this when the issue is on their end!!! Especially when that customer has been making faithful payments up into them not upgrading the system on their end!!! Can someone please recommend A good lawyer to stop them from interfering with system!!! Again, the issue is not on my end!!! I need help!!!!"

FAQs for energy efficiency auditing projects in Bay Saint Louis, MS

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.
