It’s California law. HVAC system replacements require a permit and independent inspection by a HERS Rater to verify proper and efficient operation.
Before signing a contract, make sure your HVAC contractor will provide you with a CHEERS Project Status Report.

The average California home HVAC system leaks 30% of the conditioned air into areas other than living space. To combat this massive energy loss, the State of California requires HVAC replacements to be:
- Permitted at the local Building Department
- Installed by a licensed HVAC contractor
- Tested and verified by an independent HERS Rater

Here’s a summary of the process and who does what:
Risks of not getting a CHEERS Project Status Report
A CHEERS Project Status Report is available only after a project has passed verification and testing by an independent HERS Rater. If you are working with a contractor who does not pull a permit or use a HERS Rater for final testing, your contractor is breaking the law. Unpermitted and untested HVAC projects:
- Do not comply with local and state building codes
- May not be properly installed or operating efficiently
- Increase utility bills and reduce indoor air quality
- Potentially lower home resale value and jeopardize future insurance coverage and rates
