Duct Testing, Exempt or not Exempt?

March 20, 2019, 3:30 - 5:00 PM EST

Please join us for our March webinar!


With various rules for duct testing existing in the market, it can be hard to sort out when and where a duct leakage test must be performed. The duct leakage to outside test is a minimum rated feature required for a confirmed HERS Rating unless a home meets the RESNET duct test exemption. However, if a rating is performed for code, and the code language indicates duct testing is exempt, is it exempt for a rating even if it does not meet the RESNET exemption? What takes precedence?

In this session we will discuss how duct testing is interpreted by various raters, programs, and codes in the Northeast, and what clarity may be needed in the industry going forward.
