Duct testing for Valley HVAC contractors
Replacing equipment, repairing ductwork or closing out a permitted installation? Permit Boost provides duct leakage testing across the San Fernando Valley, including Reseda, Northridge, Van Nuys and Canoga Park. Send the job address and scope so we can review the applicable ECC/HERS verification before scheduling.
Measure the duct system before final inspection
Duct leakage testing measures how much air escapes from the duct system under controlled test conditions. The applicable test method and passing criteria depend on the project scope and compliance documentation. We review those details instead of assuming that every replacement or duct repair needs the same test.
Get the site ready for the visit
Have the installer confirm that the ductwork is complete and that the equipment, registers and required access points are accessible. Let us know about attic access, occupied rooms or access restrictions when you book. Coordinating these details helps avoid a visit before the installation is ready.
Clear readings and closeout paperwork
If a result is outside the applicable criteria, we explain the readings so your contractor can make corrections and arrange a retest. We complete the applicable rater documentation through CHEERS and provide the project documents for closeout. Have a final inspection coming up? Include the date with your request so we can confirm availability.
Schedule your field verification
Send your job address, project details and preferred date. We confirm availability, the verification scope and your quote before booking.
