Casteel's HVAC Term of the Week : Damper
In Atlanta we’re privileged to have many beautiful homes. These home usually contain complex duct systems and often time these systems require a little help from zone controls. Usually a zone control board will open and close dampers which control the openings in the ducts. Basically dampers either block air or let it through. Air conditioners can work more efficiently with a damper controlled duct system.
Dampers can be controlled by motors or by manually moving the devices.
