My next door neighbor moved all her ducting to the attic. It wasn't because of mold. It was because the guy that did it showed her gravel in the bottom of the plenum. Told her it had rusted out. All the plenums in this neighborhood are open bottomed with the bottom sand and gravel!

When I moved here the vent in that same front bedroom would fill with water on a heavy rain. Water was standing just outside that room. I re-landscaped the yard so the water would drain away from the house and no more problem. Had it checked for mold and there was none. Vents are now bone dry.
