What is the purpose of a damper in ductwork?

A damper in ductwork serves the essential function of controlling airflow within an HVAC system. By adjusting the amount of air that flows through various parts of the ductwork, dampers help optimize the system's efficiency and maintain desired temperatures throughout different spaces in a building.

When dampers are correctly positioned, they can balance airflow, ensuring that each room receives the proper amount of heated or cooled air based on its specific requirements. This not only enhances comfort but also contributes to energy savings, as it allows the system to operate more effectively without overworking or wasting energy. Hence, the role of a damper is crucial in creating a well-functioning, efficient HVAC system that meets the varied demands of different zones within a residence.
