Duct leakage testing helps verify that an HVAC duct system is properly sealed and performing efficiently. Leaky ducts can waste energy, reduce comfort, increase utility costs, and create issues during permit final inspections.

The Energy Testing Company provides duct leakage testing for HVAC changeouts, alterations, additions, and other projects requiring California energy compliance verification. We work with homeowners, HVAC contractors, builders, and property owners to help keep projects moving and provide the testing documentation needed for permit closeout.

Our goal is to make the process simple: schedule the test, verify the system, identify any issues if the system does not pass, and help you understand the next steps.
