Generated explanation

A cross section of a two-story house with a basement shows cooled-air circulation through a forced-air duct system. A basement furnace and A/C unit feeds supply ducts serving registers near the exterior wall on both stories. Arrows show air moving upward from the supply registers, across the rooms, and toward centrally located return grilles. Return ducts carry air back to the equipment, with a high return grille illustrated on the upper story and a low return grille on the first story. The annotations emphasize even cooling, adjustable high/low upper-level returns, centrally located returns, and equal numbers of returns on the two stories.
