"Highly advise not to use them for any installation jobs. Sloppy work, incorrect with regulator placement and double billed after another experienced technician did the job. Even the experienced technician did a half assed job reconnecting an exhaust vent that he decided to remove to run the gas line which did not need to be removed. cannot get ahold of customer service to discuss or dispute the service bill which then has my oil and gas deliveries on hold. I prepaid for the gas delivery while under dispute and am being double billed. I may just find a more reliable local person as this big time company with small time feelis simply not working out."

Jim Moon started Gutter Helmet of New England in 1993. Gutter Helmet quickly grew and homeowners began asking him to install other products. What started as a gutter protection company, quickly grew into one of New England's premiere home improvement companies, Moonworks Home Improvement. In addition to Gutter Helmet, Moonworks also provides high quality products including; Heated Helmet, Ice Defense, Dr. Energy Saver, and GAF Roofing.

"I would void these guys like the plague. The original estimate for their "Ice Defense" system was # 3700 and I was told I needed to figure a couple of hundred dollars additional to have their electrician connect the wiring. After the install, I come to find out that their electrician actually wanted over $ 5000 to do the wiring. That's right FIVE THOUSAND ! After a months worth of e-mails and calls back and forth they finally hooked me up with a different electrician that said he got calls like these from a lot of their customers and the cheapest he could do it for was THREE THOUSAND. More calls and more e-mails and they finally agree to split the cost (to avoid small claims court), and the units are finally wired up. Of course by now the first winter is over so I never actually turn them on until the following winter. When I finally do get to use them, my first electric bill is almost $300 higher than any previous bill ever. Contacted them about that and never heard back. Just had them on this winter for ONE DAY during the last storm and my bill is almost $150 dollars higher than the previous month ... FOR ONE DAYS USE. A complete and total waste of time and money."

FAQs for energy efficiency auditing projects in Chester, NH

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.
