Title 24 HERS Compliance

Title 24 HERS Verification Services for California Energy Compliance

Call (626) 365-1518 | Alternative Energy Systems

If your building project in California includes new HVAC systems, ductwork, or high-performance building components, chances are you’ll need Title 24 HERS verification. HERS stands for Home Energy Rating System—a third-party testing requirement tied to the Title 24 Energy Code. At Alternative Energy Systems (AES), we not only help you complete your Title 24 compliance report, but we also coordinate the required HERS tests so your permit gets final approval without delay.

HERS verification is essential for ensuring that the systems and performance measures you’ve modeled in your energy report actually perform as intended once installed. Whether you’re dealing with duct leakage, airflow, fan watt draw, refrigerant charge, or high-performance attics and walls, AES ensures your documentation is complete, compliant, and city-ready.

What Is Required Under Title 24 HERS?

  1. Duct Leakage Testing
    • Required when new ducts are installed or altered. HERS raters test for leakage rates and sealing quality.
  2. Airflow & Fan Watt Draw
    • High-performance HVAC systems must meet airflow and efficiency thresholds.
  3. Refrigerant Charge
    • HVAC systems using refrigerant require proper charge and verification.
  4. Building Envelope Verification
    • Includes high-performance attic (HPA) and wall (HPW) testing for energy code credit.
  5. Quality Insulation Installation (QII)
    • Homes opting for QII credits must pass HERS inspection to confirm proper insulation methods.

FAQ: Title 24 HERS Requirements

  1. What does HERS stand for? Home Energy Rating System—California’s third-party verification program.
  2. When is HERS verification required? When new ducts, HVAC, or energy-efficient building measures are part of the project.
  3. What forms are part of the HERS process? CF-1R (design), CF-2R (installer), and CF-3R (HERS rater verification).
  4. Who performs the HERS test? Certified third-party HERS raters, independent from installers and designers.
  5. Do all HVAC projects require HERS? No, but most new or modified HVAC systems do.
  6. How do I know which tests are needed? AES includes a breakdown in your Title 24 energy report.
  7. What’s the cost of HERS testing? Varies by scope, but AES helps connect you with affordable, certified raters.
  8. Is QII required? Not mandatory, but it can improve energy performance scores for better compliance.
  9. What happens if I fail HERS testing? Your rater will explain what needs correction before retesting.
  10. Can AES coordinate my HERS rater? Yes. We work closely with raters across California for quick scheduling.
  11. Are HERS forms required for permit final? Yes. The CF-3R must be submitted and signed off for permit closeout.
  12. Can I request HERS for commercial buildings? HERS applies mainly to residential, but some small commercial projects may benefit from similar verifications.
  13. What is CF-3R? The final HERS report confirming the installed systems meet Title 24 requirements.
  14. What’s the benefit of using AES? We simplify Title 24 and HERS together—one point of contact, one permit-ready result.
  15. What systems require refrigerant charge verification? Split systems, mini-splits, and any AC with a refrigerant loop.
  16. Do ductless systems need HERS? Sometimes—if paired with new ductwork or zoned airflow measures.
  17. Is insulation inspected under HERS? Yes, if QII is selected. The HERS rater inspects for proper installation and coverage.
  18. Can I fail a HERS test for duct leakage? Yes. If your ducts leak beyond the acceptable limit, they’ll need to be resealed and retested.
  19. Can you update my Title 24 if my HERS test fails? Yes. We can adjust the energy model to reflect field conditions.
  20. How do I start the HERS process? Call AES at (626) 365-1518 or visit https://title24energy.com/contact to get started now.
