Duct Leakage Test = Comfort Delivery Test
Image(s)
Technical Description
Comfort systems often distribute heated and cooled air through ducts. If these ducts have leaky connections and holes, they can leak significant amounts of conditioned air. This results in energy loss, comfort problems, and potential moisture problems, especially when the ducts run through unconditioned spaces (e.g., vented attics and crawl spaces). Duct leakage is tested using a fan designed to pressurize the ducts along with special gauges for calibrating the rate of leakage.
