Which duct type is used to deliver conditioned air to rooms?

• A. Supply ducts
• B. Return ducts
• C. Exhaust ducts
• D. Vent ducts

Answer: (B)

Delivering conditioned air to rooms is done through the supply duct system. Supply ducts branch out from the heating or cooling equipment and carry heated or cooled air to the registers and diffusers in each room, distributing the conditioned air where it’s needed. Return ducts are the opposite path: they pull air from the rooms back to the equipment to be conditioned again, helping keep air moving in the system. Exhaust ducts vent air to the outdoors, removing stale air, while vent or ventilation ducts bring in outside air for fresh air but don’t deliver conditioned air to spaces. So the duct type that actually delivers conditioned air to rooms is the supply duct network.
