For years the common building practice for crawlspaces was to install wall vents to allow the space to breathe. Venting the area would remove the moisture from the crawlspace.
Studies have shown that this is not the case. In fact, venting this space actually brought moisture in, making the perfect environment for mold growth.
With the addition of Air Conditioning this becomes even more of an issue. The hot moist air condensing when it meets the cold ducts and framing.
Watch this short video on the case study of vented vs. closed crawlspaces.
