Air grilles connect to ductwork that allows air to return to any cooling or heating system. The opening that connects to air ducts and other places for returning air is normally covered with grillwork. Grille boxes are vents that cover an air duct, through which air is blown into or out of a room for circulation back to the central heating or cooling unit. They are typically found in homes with central heating or air conditioning. A grille damper helps to control airflow, so air is left to flow freely. grille_boxes grilles
