Dampers in duct systems are used to do what?

• A. Adjust airflow into each room
• B. Seal leaks
• C. Filter air
• D. Cool the air

Answer: (A)

Dampers are used to control how much air reaches different parts of a duct system. By adjusting the opening of the damper blades, you can increase or decrease airflow to individual rooms or zones, which helps balance the system, maintain comfortable temperatures, and improve energy efficiency. In modern setups, dampers are often motorized and coordinated by a zone controller or thermostat to create distinct comfort zones. They aren’t meant to filter air, cool the air, or seal leaks—those functions are handled by filters, the cooling/heating equipment, and proper duct sealing, respectively.
