Keeping your home or business energy-efficient in California isn’t just an eco-friendly choice — it’s the law. The combination of HERS testing and Title 24 compliance ensures that buildings across Sacramento, El Dorado Hills, Folsom, Roseville, Rocklin, Davis, Vacaville, Granite Bay, Auburn, Stockton, Bay Area, Napa, Sonoma, San Francisco, San Mateo, Santa Clara, Marin, Lake Tahoe, and nearby areas meet strict energy standards while saving money over time. In this all-inclusive guide, we’ll explain what HERS testing is, why it’s required under Title 24, and how homeowners, HVAC contractors, and builders throughout these locations can quickly achieve compliance.
What is HERS Testing and Why is it Needed for Title 24 Compliance?
HERS testing — short for Home Energy Rating System testing — is required by the California Energy Commission to verify that a building is as energy-efficient in reality as it was on paper in the Title 24 Energy Compliance Report. If your project requires a permit (for new construction, HVAC changeouts, duct relocations, or remodels), you must complete a HERS test before the permit can be closed.
Licensed HERS Raters perform on-site tests like duct leakage, airflow, blower door, and refrigerant charge to certify compliance. The completed paperwork (CF1R / CF2R / CF3R forms) is filed through a HERS registry such as CHEERS or CalCERTS to satisfy Title 24 requirements.
Step-by-Step: How the HERS Testing Process Works
- Energy Modeling & CF1R Title 24 Report
Before construction or installation begins, a Title 24 Report (CF1R Form) is prepared based on your building plans. - HVAC Installation or Building Alterations
Systems like ducts, insulation, furnaces, or AC units are installed according to CF1R requirements. - HERS Testing Performed On-Site
A certified HERS Rater visits the property in Sacramento, El Dorado Hills, Folsom, Bay Area, or whichever location you’re in to perform mandatory field tests. - Submission of CF2R / CF3R Forms
Passed results are uploaded to the HERS registry and approved. - Permit Closed & Final Inspection
The local building department accepts your HERS paperwork and closes your permit under Title 24.
Types of HERS Tests You May Need
Whether your project is in Sacramento County, Placer County, El Dorado County, or across the Bay Area, typical HERS testing can include:
- Duct Leakage Test – Measures how much air is escaping from ducts. Required when replacing, relocating, or installing HVAC units.
- Airflow / Fan Watt Draw Test – Confirms AC systems in places like Folsom or Roseville are delivering proper cubic feet per minute of air.
- Refrigerant Charge Verification – Ensures refrigerant is correctly balanced in new split systems.
- Blower Door Test – Evaluates the overall tightness of a building envelope to reduce drafts and energy loss (common in Granite Bay, Tahoe, Napa retrofits).
- QII (Quality Insulation Installation) – Verifies proper insulation installation in new builds across Sacramento, Rocklin, and Auburn.
- IAQ & Ventilation Verification – Ensures proper indoor air quality and kitchen/bath fan ventilation to meet Title 24 codes.
Explanation of Key Terms
- Title 24 Compliance – California’s building energy efficiency standards that require documentation and testing.
- HERS Rater – Certified professional who conducts testing and submits compliance forms to CalCERTS or CHEERS.
- CF1R – Initial Title 24 energy model submitted at plan stage.
- CF2R – Installation certificate completed by HVAC contractor.
- CF3R – Final verification results completed by a HERS Rater after testing.
- Duct Leakage – Percentage of conditioned air escaping from a duct system during operation.
