Sub slab Ductwork Encounters

I recently inspected a house for a client in Montgomery, AL that was concerned about moisture and mold in a home that they had purchased 4 months earlier. The home was built in 1989 and had a slab foundation. We found several sources of moisture from failed thermal panes in aluminum framed windows to bathrooms without ventilation/window/or fan with carpet. The greatest source of moisture by far was the sub slab ductwork. Once we ran our chimney camera down into the ducts we found over 4inches of standing water. The client pumped out just over 372 gallons later that day. The water was entering at the exterior where the single package unit was tied to the ducts. I realize the potential flaws of this construction and why its not more prevalent. Has anyone else had experience with sub slab ductwork? Also, I love the utility capability of these 360degree cameras, technology makes such a difference for this http://eahi.biz."> Auburn Home Inspector, http://eahi.biz.
