Home Energy Assessment

Home energy assessments help homeowners understand their residential energy consumption by analyzing energy flow. Energy assessments typically provide a report on your home’s energy use and help determine the most cost-effective home improvements. They may also provide results on radon, carbon monoxide, and natural gas leak testing to help keep your home safe. If you are interested in learning more or scheduling your own home energy assessment you may want to check out Xcel Energy and Efficiency Works.

Contractor Requirements

You must use a participating contractor in order to qualify for this rebate. Ask your contractor for the rebate application.

High-efficiency solutions for your home are only as “highly efficient” as the Quality Installation techniques used by your contractor. There is no state-wide licensing program in Colorado for residential contractors, so national certification programs have been selected to ensure contractors have the necessary technical knowledge and expertise. Once they meet the program requirements, they are added to the participating contractor list and are given access to the rebate application.
