Cal Star Energy Rating | Emergency HVAC Repair in Fontana, CA

Our HERS-rated energy audit is a comprehensive diagnostic process. For your Fontana home, our certified inspectors conduct field verification and testing to measure duct efficiency, envelope air leakage, refrigerant charge, and insulation levels. This data creates an official rating of your home's energy performance and identifies specific areas where upgrades can improve comfort and efficiency to meet California's building standards.

Absolutely. While our primary audit focuses on the building's overall energy performance, the diagnostic testing process often uncovers underlying HVAC issues. For example, checking duct efficiency and system performance can reveal problems that might cause a smart thermostat to malfunction. Similarly, assessing the HVAC system's operation can identify if a clogged condensate drain line is impacting efficiency. We provide the data homeowners need to address these common local problems effectively.

In California, official HERS ratings for compliance and many incentive programs must be performed by a rater certified by the California Energy Commission (CEC). As a CEC-certified provider, Cal Star Energy Rating ensures your Fontana home's rating is accurate, recognized by building departments, and valid for programs like solar installation or energy upgrade rebates. Our long-standing local experience means we understand the specific application of these standards in our region.
