In a recent inspection, I observed soggy flex duct due to elevated moisture in the crawl space, not flooding conditions. The crawl space has a medium amount of mold growing on the floor joist and sub flooring. This was a vented crawl space that someone forgot to open the vents to the crawl space. This was missing a vapor barrier over 50% as well. This created rain like conditions in the crawl space. Should the flex duct be replace or can the crawl space be dried and flex duct be dried out? In this crawl space I located about 5 ducts that were soggy and hanging down. My other question is, once the flex duct insulation is soaked, does this create conditions inside the flex duct conducive to mold growths?

Once any insulation is wet generally it should be replaced. I'd note the defect and let a HVAC tech make the call.
