Rigid ducts are durable and are usually used for which duct part?

• A. Main trunk ductwork
• B. Branch ducts to individual rooms
• C. Return air paths
• D. Outdoor exhaust vents

Answer: (B)

Rigid ducts are durable and resist deformation, which helps keep air moving consistently through long or intricate runs. The portions that extend from the main trunk out to each individual room benefit most from this stability because they must navigate walls and ceilings, meet multiple elbows, and connect to several registers. Using rigid metal duct for these branch runs minimizes leaks and pressure losses, preserves the intended airflow to each room, and makes the system easier to seal and maintain over time. That’s why branch ducts to individual rooms are typically made with rigid ducting.
