HERS Testing vs. Title 24 Compliance – What’s the Difference?
Call (626) 365-1518 | Alternative Energy Systems
If you’re building or remodeling in California, you’ve likely heard about **Title 24 compliance** and **HERS testing**. While they’re both required by the state’s energy code, they serve very different purposes. At Alternative Energy Systems (AES), we help property owners, contractors, and architects understand and fulfill both requirements with ease.
HERS Testing vs. Title 24 Compliance: What’s the Difference?
**Title 24 compliance** refers to the **energy efficiency documentation** that must be submitted during the plan review stage of your building permit process. This includes a detailed energy report—called a CF-1R form—that confirms your building design meets California’s energy performance standards.
**HERS testing** (Home Energy Rating System) happens later—**after construction**. It’s a set of field verifications performed by a certified HERS rater to make sure your installed systems (HVAC, ductwork, insulation, etc.) match what’s in the Title 24 report.
In simple terms: **Title 24 is the plan. HERS is the proof.**

FAQ: HERS vs. Title 24 Compliance
- What is the main difference between HERS testing and Title 24?
Title 24 is the energy compliance report filed before construction. HERS testing is the field verification that happens after the work is done. - Is HERS testing always required?
In many cases, yes. Projects involving HVAC, ductwork, or building envelope changes often require HERS testing. - Can AES provide both?
Yes! AES handles both Title 24 reports and HERS testing services statewide. - When should I request a Title 24 report?
Before you submit your building plans for permits. It’s part of the plan check process. - When is HERS testing done?
After construction, before final inspection—usually once systems are installed and operational. - Can I skip HERS if I already did Title 24?
No. They are separate steps. One is documentation; the other is field verification. - What’s included in HERS testing?
Tests include duct leakage, airflow, refrigerant charge, QII (insulation verification), and more depending on your project scope. - How long does HERS testing take?
Most tests are completed in under a day. AES helps schedule and coordinate it with your build timeline. - Is AES certified for HERS?
Yes. We work with certified HERS raters approved by California registries like CHEERS and CalCERTS. - What if my project fails HERS?
We’ll help you identify what needs to be fixed and retest quickly to keep your project moving forward.
