Welcome to CalCERTS!

Quality Assurance Reviewers

When your new or replacement furnace, air conditioner, or duct work was installed, that work should have been verified by a HERS Rater per California’s Title 24 Energy Efficiency Standards. Those HERS Raters are trained, licensed, and overseen (but not employed by) HERS Providers; CalCERTS is one such provider. We are mandated to perform Quality Assurance review on all of our HERS Raters in order to ensure truth, accuracy, and completeness of work. CalCERTS Quality Assurance Review will follow the exact same testing protocol followed by the initial HERS rater, and there is NO CHARGE to the homeowner.
