In 2006, the California Energy Commission approved the HomeEnalasys™ Third Party Quality Control Program (TPQCP), developed by Enalasys Corporation which allows one out of every thirty HVAC jobs to be verified by a an independent HERS Rater compared to one out of every seven jobs. On July 22, 2014 Enalasys was re-certified as a Third-Party Quality Control Program under the providership of US Energy Raters Association.

Because of our cutting edge, patented tamper proof technology, HVAC contractors can be more efficient and compliant in their alteration and installation of HVAC energy units.

"HERS raters are to be considered special inspectors by enforcement agencies and shall demonstrate competence, to the satisfaction of the enforcement agency, to conduct the required visual inspections and diagnostic testing of the regulated energy efficiency features installed in the dwelling."
