What is ECC testing and why is it required in California?

ECC (Energy Code Compliance) testing verifies that a home or building meets California Title 24 energy efficiency requirements. Starting January 2026, the California Energy Commission transitioned the HERS program to the new ECC Program. Testing includes duct leakage, blower door, QII, and refrigerant charge verification — required for permit sign-off and building department approval.

What is the difference between HERS and ECC testing?

Starting January 2026, the California Energy Commission transitioned the HERS (Home Energy Rating System) program to the new ECC (Energy Code Compliance) Program. HERS raters are now called ECC Raters. The testing itself — duct leakage, blower door, QII, refrigerant charge — remains the same; only the terminology changed. T3 Energy Inc. is fully transitioned to ECC Rater certification.

How much does ECC testing cost?

ECC testing pricing depends on project scope, location, and the specific tests required. Single-family residential tests typically start in the low hundreds. Contact T3 Energy Inc. at (916) 757-4588 for a free custom quote within 24 hours.

How long does ECC testing take?

Most residential ECC tests take 1–2 hours on-site. Commercial projects may take longer depending on the number of systems and tests required. T3 Energy Inc. provides complete documentation the same day in most cases.

What do I need to prepare for an ECC test?

Your HVAC system must be installed and operational, ductwork complete and accessible, thermostat installed, and electrical service connected. For blower door testing, all exterior openings should be closed. We'll provide a pre-test checklist when you schedule.

When should ECC testing be scheduled during construction?

ECC testing should be scheduled after HVAC installation and ductwork are complete, but before the final building inspection. Some tests like QII require inspection before drywall is installed. Contact us early in your project timeline to plan the right testing sequence.

What happens if my building fails an ECC test?

If your building doesn't pass, we'll identify the specific issues — such as duct leakage exceeding limits or airflow below design — and provide guidance on what needs to be fixed. Once repairs are made, we can re-test. Most issues are resolved with minor HVAC or sealing adjustments.

Does ECC testing qualify me for utility rebates?

Yes. Most SMUD, PG&E, and Roseville Electric rebate programs require third-party ECC verification. T3 Energy Inc. performs the required testing and handles the rebate documentation directly with the utility so you can claim every available dollar.
