It might not sound like it, but condensation on ductwork can be a serious problem, causing all sorts of secondary problems like leaking ceilings and mold growth. Condensation on ac ducts is more of a problem in the south where humidity levels are generally higher, but it can happen anywhere in the country.

This presentation will discuss the issues with duct sweating in sealed attics and traditionally vented attics as well as two-story floor systems. We will address how this condensation forms on the ducts, why the condensation can be a problem, the causes of condensation on ductwork, and what can be done to prevent condensation on ducts
