What does a zone damper do?
A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to improve efficiency and occupant comfort, HVAC systems are commonly divided up into multiple zones.
How do you check a zone damper?
Put the damper into an open position and check the registers once again to see if the airflow starts. If the damper is closed and you are feeling low airflow, or none at all, it is most likely a bad damper. For the automatic control damper, turn your HVAC system on. Check for airflow in the registers.
