"I needed an inspection done on our new home. This is an older house so I had some concerns. Bill was incredibly thorough and professional. His report was detailed and left no questions about any of the info provided. He allowed me to arrive at the house after the inspection and review some things he found.

"Extremely dissatisfied with my consultation! First off, booked an appt due to Toilet tank seal leaking and needing to be repaired/replaced. I book an appt for them to charge me $89 for them to tell me exactly what I told them was wrong in the first place. Second, the options presented to me where astronomical and absurd. I'm talking about a toilet repair mind you! $1375 for them to replace my toilet altogether. $591 to install a toilet that I purchase. Or 721 to rebuild the current toilet. I settled for paying $89 for those options I suppose so Free Estimate as advertised isn't correct! I'm an Army War Veteran and I refuse to be ripped off by companies like this one. I can buy a brand new toilet at Home Depot for $1-300 and install it myself in under an hour. Thanks for nothing and enjoy my $89!!!"

"I would recommend taking your business elsewhere. We signed a contract with them in Nov '21 for work to be completed in May '22 for a large multi-house project. In Nov '22 the work was finally "completed." Throughout that time there was minimal to no communication. I would get text messages about a work crew coming to work on the install and no one would ever show up. I would get last minute text messages asking for access to inside areas they had previously claimed they didn't need access. I have had them call and inform me that a "string of panels" was not functioning, only to have the tech arrive and say everything looks fine and it's all working. I still have never been given access to the system monitoring software, despite claims that I have, so I have no way of verifying if anything is working outside of random screenshots they send of their computer monitors. On of the least professional companies I've encountered. Save yourself the headache and look elsewhere."

FAQs for energy efficiency auditing projects in Darmstadt, IN

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.
