Professional duct leakage testing (duct blaster) to measure how much conditioned air is lost through your duct system. Required for many Title 24 compliance paths — same-day results and filing.
A duct leakage test uses a calibrated device called a duct blaster to pressurize the duct system and measure how much air leaks out through gaps, loose connections, or poorly sealed joints. Duct leakage is one of the leading causes of energy waste in California homes.
California Title 24 requires duct leakage testing for many new construction and HVAC replacement projects. Roo's Ratings performs both duct leakage to outside (TDL) and total duct leakage tests, with results and HERS/ECC certificates filed the same day.
We can perform a duct leakage test as a standalone service or add it to any HERS/ECC inspection on the same visit for a significant discount. Most contractors add it to an existing inspection visit to save time and money.
The most common test for Title 24 compliance — measures how much air leaks from the duct system directly to unconditioned space or outside the building envelope.
Measures all duct leakage, including air moving between conditioned spaces. Required for certain compliance paths and utility rebate programs.
Pair a duct leakage test with a blower door test for comprehensive air leakage reporting — the most common combination for new construction projects requiring both for Title 24.
