What are the Return ducts?

• A. The ducts that return air to the air handler for distribution
• B. The ducts that supply conditioned air to rooms
• C. The ducts for venting exhaust
• D. The ducts for refrigerant lines

Answer: (A)

Return ducts are the ducts that collect air from the rooms and bring it back to the air handler so it can be cooled or heated again and redistributed through the supply ducts. They complete the loop of the HVAC system by feeding the air handler with the space air, ensuring the system can condition and recirculate air efficiently. This is different from supply ducts, which push conditioned air out to the rooms, and from exhaust pathways, which vent air outside. Refrigerant lines, on the other hand, are part of the cooling circuit, not air ducts. So the described function—returning air to the air handler for reconditioning and redistribution—defines the return ducts.
