Duct Leakage Tests

The International Code Commission (ICC) mandated HVAC duct leakage testing for the first time in the 2009 International Energy Conservation Code (IECC).

Leaking conditioned air to unconditioned spaces is wasteful and unnecessary. There are many duct sealing systems available that will fill most of the small openings around duct fittings. To seal ducts and conduct a leakage test, a HVAC contractor, engineer, or HERS rater use these specialized tools and metho

The installed equipment was very heavy and overbuilt. That all changed in the late 20th century due to several economic and environmental factors. These factors created a new buzzword: energy conservation.
