Knowledge Base
What is a HERS Test?
HERS stands for Home Energy Rating System, a program developed by California to ensure that homes meet strict energy efficiency standards.
HERS testing is often required when installing new HVAC systems, building a new home, or completing major renovations. A certified HERS rater performs a series of field tests and inspections, including duct leakage, airflow, insulation quality, and more — all designed to confirm energy compliance and improve home performance.
