â Rebecca, Plymouth, ME. A: Richard Trethewey replies: You can run a duct in a crawl space, but you must take some precautions. First, the duct should be insulated for two reasons: to keep the heat in the duct until it can get to the room and to keep the duct from sweating and rotting away. A hot duct in a very cold space can cause water vapor to settle along the duct, causing rust (on metal ducts) and mold (on any duct).
