Ventilation systems usually run through crawl spaces, so leaky ductwork, coupled with pest or mold infestation can result in air contaminated with rodent droppings, decaying food cached by pests and mold spores. Pests, and trapped water can damage vapor barriers, resulting in still worse damage like mold and rotten structural materials. And poorly insulated crawl spaces can spill expensive heat into the winter night. Fortunately, all of these potentially costly crawl space issues can be avoided.
