HERS is now ECC

One required process. A clearer way through it.

California’s 2025 Energy Code moved field verification and diagnostic testing from the former HERS compliance program into the Energy Code Compliance (ECC) Program. Many contractors and building departments still say “HERS test”—and that is the service people are looking for.

Our certified raters test the measures listed on the approved compliance documents, record results through the applicable registry workflow, and help keep permits moving toward final approval.

Comprehensive FAQ

Answers before we arrive.

Clear guidance for homeowners, contractors, builders, and permit teams.

Is a HERS test the same as an ECC test?

ECC is the current field-verification program name under the 2025 Energy Code. “HERS test” remains the familiar industry term.

When is ECC field verification required?

Requirements depend on the building type, permit date, project scope, compliance approach, and approved documents. Many new residential projects and HVAC alterations include field-verification measures; the registered compliance documents identify what applies to a specific job.

How do I know which tests my project needs?

Review the CF1R and registered project documents. Send us those documents, the permit, scope, and address so we can confirm the applicable verification forms.

Do kitchen range hoods require verification?

Some projects require local mechanical exhaust verification under CF3R-MCH-32-H. The installed hood must be accessible and operational for airflow and applicable sound or label checks.

Are bathroom exhaust fans tested?

They can be included in local mechanical exhaust verification when required by the project documents.

Why must the ECC rater be independent?

Independent third-party verification protects the integrity of testing and prevents the installer from grading its own work.

What should be ready before the appointment?

Construction and HVAC work should be complete for the scheduled stage, equipment operating, filters installed, registers accessible, and required documents available.

What areas must the rater access?

Indoor and outdoor equipment, all supply and return registers, thermostats, electrical disconnects, and applicable attic, crawl-space, envelope, or exhaust locations.

How long does testing take?

Many single-system inspections take approximately one to two hours. Larger homes, multiple systems, QII, envelope work, and multiple measures require more time.

Do I need to be home?

An authorized adult must provide access unless access has been arranged with the contractor or another responsible person.

What happens if a measure fails?

We explain the failed measured item. The responsible installer performs corrections, and the affected measure is retested when ready.

Do you repair HVAC systems?

No. We verify and document independently; we do not sell equipment or perform the repairs we inspect.

What are CF1R, CF2R, and CF3R documents?

CF1R is the Certificate of Compliance, CF2R is the Certificate of Installation, and CF3R is the Certificate of Verification completed for applicable ECC measures.

Who signs the project documents?

Signatures depend on the document and role. Responsible designers, installers, responsible persons, and ECC raters sign the documents assigned to their work.

What is CHEERS?

CHEERS is a CEC-approved ECC Provider that supports certified raters and operates an approved residential data registry.

My project was in CalCERTS. What happens now?

Send the available CalCERTS records, address, permit, and current status. The project may need to be re-established through the current CHEERS workflow.

Can testing be done after walls or insulation are covered?

Some measures can; stage-sensitive QII, air sealing, duct, and envelope inspections may not be verifiable once concealed. Contact us before covering work.

Are there duct-leakage exemptions?

Some existing systems may qualify for specific exceptions or alternative documentation. Eligibility depends on the actual system and applicable Part 6 requirements.

Is a blower-door test always required?

No. It applies when identified by the project’s compliance approach and documents.

Can you help close an old permit?

Yes, within our scope. We review the available permit and compliance records to identify missing field verification and registry steps.

Do you work directly with contractors?

Yes. We support single projects and ongoing contractor workflows with organized intake, scheduling, testing, and status communication.

What information should I send for scheduling?

Full address including unit, permit number and date, project scope, CF1R documents, contractor and responsible-installer details, billing contact, and preferred appointment window.

How quickly will documents be completed?

Timing depends on passing results, complete project information, required signatures, and registry readiness. We identify missing items rather than promising an inaccurate deadline.

Does passing ECC testing close the permit automatically?

No. ECC verification supports Part 6 compliance; the local enforcement agency controls inspections, final approval, and permit closure.
