An HVAC damper (also called a duct damper) is a movable plate, located in the ductwork, that regulates airflow and redirects it to specific areas of the home. Dampers are typically used in zoning or “zone control” systems.
Keeping this in view, how do you find dampers in ductwork?
- Turn the lever on all the registers inside the house to the full open position.
- Open the door or access panel to the attic and examine how much lighting is available.
- Go into the attic and follow a duct from the furnace to find the damper inside of the ductwork.
- Turn each damper to the full open position.
Also to know, where are dampers located?
Go into your basement or attic and find the dampers. Usually, they are positioned somewhere in the “take-offs” or “branches” of the duct system. With manual-type dampers, they have either a rod that you can adjust using a screwdriver or a lever that you can turn by hand.
Whether closing supply air dampers will cause a problem; if there's not too much static pressure in the system, closing off supply dampers might actually be ok! The only way to know is to measure static pressure and make sure it aligns with HVAC system manufacturer specifications, even when the dampers are closed.
