5 Star Rated HERS Rater
Responsive Testing, Meticulous Balancing, and Submission-Ready Paperwork
- CF-2R & CF-3R Registered
- Residential & Commercial
- Scheduled Around Your Install
A-Class HERS Raters is a CHEERS-certified HERS / ECC rater handling the Title 24 verification your final city approvals rely on: duct leakage, refrigerant charge and airflow, QII, and full air balancing for homes and commercial spaces across Los Angeles, Orange and Ventura counties.
Testing isn't just about passing inspection; it's about optimizing performance. We pinpoint air loss and system drag so you can implement precise fixes, protect your bottom line, and ensure long-term energy efficiency.
What we do
All Required Title 24 Field Testing, Handled by a Single Certified Rater
No chasing three vendors around one inspection date. We test, we balance, and we register the forms.
Air Balancing
Room-by-room airflow measured and adjusted to design CFM, with a test & balance report for every register and return.
What's InvolvedCF-2R & CF-3R Forms
Compliance and installation certificates completed and registered, matching exactly what was installed.
What's InvolvedDuct Leakage Testing
Calculates hard leakage percentages against permitted code allowances to ensure full regulatory compliance.

Insulation verified before drywall closes it in, plus ventilation and indoor air quality checks newer code requires.
