When should you adjust a balancing damper?
So, you'll want to adjust your dampers to provide less airflow upstairs and more airflow downstairs—because the warm air will naturally rise. In the summer, you'll want to do the opposite. (If you have a one-story home, simply adjust the dampers to provide more warm/cool air to the rooms you use most often.)
What is an HVAC balancing damper?
A damper in an HVAC system, also known as Duct Damper or Volume Balancing Damper is a movable plate, situated in the ductwork that regulates the flow of air and redirects it to specific places of a house. The usage of dampers is typically seen in zoning or zone control systems.

How do damper systems work?
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 balance my HVAC airflow?
Add or remove supply and return ducts to deliver enough air to each room. Seal or insulate accessible under-insulated ducts. Add dampers to the ducts. This directs the airflow coming from the HVAC unit and shifts the desired amount to each room.

How do you tell if dampers are open or closed?
If you are looking at a duct that is coming off the furnace and going straight up like it is going to the upstairs, and the wing is in the same direction as the duct, it is open. If the wing is in the opposite or vertical position to the ductwork, then the damper is closed.
How do dampers work in buildings?
They work by reducing the amplitude of vibrations during an earthquake. When a building sways in one direction during an earthquake, the motion of the damper lags behind. After a few cycles, the damper is moving in the opposite direction as the building, and this reduces the overall sway.
Where are the dampers located?
The most standard dampers are found a few feet from the base of the HVAC unit. As you enter your crawl space or air handler unit in a closet, you notice the main connections to the trunk of the HVAC unit. Most homes with a second level will have dampers in their HVAC system.
Where is the HVAC damper located?
HVAC dampers are most commonly located in the main trunk line right before and after any major junctions. They can also be located at certain points on multiple system ducts, with two dampers found on every main line 90 degrees apart.
How many types of dampers are there in HVAC?

How do dampers work?
This simple action can serve many purposes, such as directing airflow to a specific part of the building or for mixing hot and cold air streams for air conditioning. Control dampers open and close constantly throughout the day. They ensure that every room in the building has fresh air, conditioned to the right temperature.
How do dampers help with air pressure?
Balancing dampers alleviate pressure imbalances by adjusting their blades to the correct angle. Technicians check the air pressure in the room as they adjust the blades. Once the correct pressure is found, the blades are locked in place. If air conditions change, the blades can be unlocked and re-positioned to adjust air pressure.
What happens to damper blades when air conditions change?
If air conditions change, the blades can be unlocked and re-positioned to adjust air pressure. Typically, balancing damper blades will always remain in the same position.
What is a control damper?
A control damper is best used to direct airflow through the HVAC system. There are more dampers than balance and control. Read up on the five main types of dampers in our Newsstand article: Five Types of Dampers and When to Use Them.
What is a damper in a room?
Balancing dampers regulate the air pressure through duct work, ensuring connected rooms are balanced. A room with too much or too little air pressure may suffer from slamming doors or random drafts of air.
Why is air pressure imbalance important?
It's important to have balanced air pressure throughout your building.
Can a damper be fully adjustable?
A control damper’s blades are not fully adjustable to any angle. They can only operate in two positions: with the damper fully opened or fully closed. This is the primary difference between control dampers and balancing dampers. This difference dictates how each damper operates and its intended uses.
