HERS Testing Experts

Don’t get delayed on your project. GM Builders HERS Testing was born from a developer who was tired of the incompetence of the available raters out there and decided to get trained and certified himself. The paperwork submitted through the online system which shows up on the inspector's end is half the battle and it's crucial that it's done correctly. Truly, I think most of the guys doing this don't have the critical thinking skills needed to do the computer portion properly or overcome the complications and they try to cheap out by not registering the documents because it costs $ to register them. The building departments are now getting audited by the California Energy Commission so the inspectors and their supervisors demand the paperwork from the rater to be perfect and if it's not the Certificate of Occupancy will be delayed.

We do Rater verified CF2R, HERS Report/CF3R, cheers, CalCERTS Certified, HERS, duct leakage, and refrigerant charge.
