"Our experience with Earth Right has been impressive from the start. Joe came to our home twice to examine the feasibility of going solar, since we live in a wooded area. The creative approach of combining our garage and house rooves in order to have enough space for the panels was far and above the other companies saying YES or NO from the satellite photos alone. Today Jeremy and Jonathan installed the foil and fan in our attic. They could not have been more professional or considerate in their approach. Installation scheduled for fall. We are sure we chose the right company... Earth-Right!"

Energy Efficiency Auditing FAQs, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

There are a couple of ways you can save on the cost of your home energy audit.

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.
