What is a damper in HVAC?
An HVAC 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 or to distribute air flow to specific regions. Most homeowners probably do not know about dampers and its role in helping regulate the temperature in your property.
Adjusting the balancing damper is like turning a lever to open or close it. You do not want to change the wrong part of the HVAC system. Make sure to label where it all leads – e.g. Bathroom, Master Bedroom, etc. If you want to heat your home, you do the opposite.
