HERS Verification and HERS Raters

What is a HERS Rater?

A Certified HERS Rater obtains a certification from an accredited Rating Provider. The only two approved HERS Providers in California are CalCERTS and CHEERS. A California HERS Rater must be certified by at least one of the two. RESNET is an approved HERS Rater for outside the state of California. The DuctTesters Team has some HERS Raters certified by all three.

A HERS Rater inspects, verifies, and tests a home to make sure it meets or exceeds the minimum required compliance or features to earn a HERS Rating. This process is often referred to as HERS Verification.  In California, HERS Rater’s verify and document the Title 24 requirements. DuctTesters has a large team of Certified HERS Raters covering the entire state of California and Nevada. The team is HERS and HERS II Certified to cover all testing, verification, and documentation. Additionally, DuctTesters covers select areas in AZ, CO, and NM.
