The State of California is committed to reducing energy used by Heating, Ventilating, and Air Conditioning (HVAC) systems. The HERS program was initially implemented to address construction defects, and equipment installations that had historically not been done correctly. These HERS measures cover HVAC systems, and insulation installations.
To meet these energy goals, all homeowners and the installing contractors are required to comply with the requirements of the California Code, which requires Field Verification and Diagnostic Testing (FV/DT).
Your HERS Rater will advise you of the required tests. Below are some of the testing requirements that may apply to your job.
- Duct Leakage Testing
- Airflow and Fan-Watt Draw (FWD)
- Refrigerant Charge Measurement
