The Return Air Grille covers the opening where air is drawn back into the heating system. It allows for proper airflow while preventing large objects from entering the ductwork. This grille is an important aesthetic and functional component of the air distribution system. When replacing a return air grille, ensure it matches the dimensions of the opening and provides adequate free area for airflow to avoid restricting system performance.
