Excessive static pressure inside an HVAC system is never a good thing.
Closing too many air supply dampers could put you in the static pressure “danger zone.”.
How does a damper work in HVAC?
HVAC dampers work by being situated closer to the mouth of the distribution pipe and will push or hold air from that point as needed. The pressure in the pipe will then redistribute the airflow to whatever zone requires regulating at that time.
How do I know if my HVAC damper is open?
Check the registers to see if the airflow has ceased. Adjust the damper to the open position and once again check the registers to see if the airflow has resumed. If you feel airflow when the damper is closed, or no airflow when the damper is open, the damper is most likely bad.
How do dampers work?

What does a fresh air damper do?

Should furnace damper be open or closed?
To adjust air flow for summer cooling, start by fully opening all second floor dampers. Next, partially close dampers to first floor rooms that are getting lots of cold air. You will find that closing the damper to 50% or turning the shaft to 45 degrees will only partially slow the air flow.
Do HVAC have dampers?
Now, it’s time to locate the dampers. 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.
