Duct leakage to outdoors tests are needed, even if duct work is within the conditioned space
If ducts are installed completely within the conditioned space do we need to test them? The International Energy Conservation Code (IECC) requires we only test duct work if it is outside the conditioned space, such as an un-insulated attic or basement. If we do test them, is total duct leakage enough, or are these leaks still finding their way to the outside? These questions are always popping up on online HVAC communities.
Looking at the surface of the issue, it might appear to be pointless to do a duct leakage to outdoors test if the ducts are completely contained within the envelope. This would be the case if the ducts themselves were on the “surface” but most are hidden in wall cavities, which often connect to the outdoors to some degree. Any duct leakage will then be partially to the outdoors (via the walls) as well as to the indoors.
