To open the damper, you should turn the lever at a position where it's paralleled with the duct. This allows the air to flow through the ducts to its fullest. Then, adjust the lever to a position horizontal to the duct to close it.

Similarly one may ask, where are dampers in ductwork?

Those two situations aside, locating your dampers should be pretty straightforward. Go to your furnace (be it in a utility room, crawl space, basement, etc.) and look at the main duct trunks radiating off the furnace. Dampers are almost always within 2-6 feet of the main trunk.

Beside above, is it OK to close HVAC dampers? 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.

Herein, how do I adjust my AC vents?

  6. Clean the vent if blocked by dirt or debris.

Do all HVAC have dampers?

A typical HVAC system delivers climate control via multiple zones by using an automated zone damper or duct damper. Only by using an actuator-controlled automatic zone damper can the system regulate the amount of air the HVAC system produces. Actuators in HVAC systems control the dampers.
