"We have had NECS to our home several times for different projects: energy audit, attic insulation, and wall insulation. These are very professional, considerate, and honest people to do such work in your home. Our house is much more energy efficient after all we have done. Insulation pays for itself very quickly, and NECS took care of all incentive programs for us. You won't go wrong with them."

"I rated them B for responsiveness because the first time I called I was told they would call back and they did not. As you would expect the price was too high. They ended up tightening a union of pipes and testing to see if it leaked. The first time it was tightened, it did leak and they went to replace the part. A second tech tightened it further, retested and it did not leak.Not sure why the first person didn't tighten further. So the question remains; is the problem solved. We will see when the heating season begins. The techs were young, personable and seemed knowledgeable and willing to answer all my questions. They spent over two hours here, some of it waiting to get the heating up for testing. Had a $50.00 coupon or the cost would have been over $400."

"The work he did was good but they did charge too much for the work. They did try to upsell other services. The charge for the additional work was too much. The charge for the part was very high. I did not have them do the additional work."

"They did an excellent assessment, were good listeners for our goals, gave us updates as to when the custom windows would arrive, installed promptly and expertly respecting our time limits due to our children's nap schedule, cleaned up, communicated with us through the installation, and we have had reductions in our energy bill since the installation.

Energy Efficiency Auditing FAQs, answered by experts

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.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

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.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200
