When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. When excessive moisture or water accumulates in the air duct system, mold growth will often occur, particularly if the moisture problem remains undiscovered or un-addressed. Some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as skin irritation, eye irritation or nasal stuffiness.
