Return registers are usually installed up high on inside walls. Where would you place a return register?

• A. Up high on inside walls
• B. On floor near entry
• C. On exterior walls
• D. In the attic

Answer: (A)

Return air is meant to be drawn from the living space and sent back to the furnace to be reconditioned. Placing the return high on an interior wall makes that air intake representative of the room's conditions without pulling in outdoor air or attic air. Air in a room tends to stratify, with warmer air near the ceiling; a high inlet helps capture air that’s circulating already and promotes better mixing and overall comfort. It also avoids drafts or pressure problems that can occur if the return is placed on an exterior wall, on the floor near doors, or in the attic. So the usual placement—high on an interior wall—supports efficient, balanced, and comfortable air circulation.
