How Are The Vent Dampers Useful In Duct System
Vent dampers manage the airflow in the duct system. They are a main component of any duct system. It is an effective way of controlling the amount of air that is passing through the ducts. It is necessary to regulate the airflow in a duct system because it is a significant factor in the overall performance of the duct. The amount of airflow that flows through a duct is dependent on the pressure differential that is present in the vent dampers.
A crucial component of your zoning system is HVAC dampers. They act as duct valves, identifying which area of your house needs how much heated or cooled air to achieve the correct temperatures. Dampers let you regulate the flow of air to various areas of your property since cold air sinks and hot air rises.
Top Four Different HVAC Damper Types
An HVAC system contains several different types of dampers, and each one has a specific function. To help you choose the best dampener for your house, let’s break down what each type of dampener performs. Additionally, we provide the best air duct cleaning service in Atlanta GA.
Flat butterfly dish dampers
The name of these dampeners comes from the way they appear—they resemble little butterflies perched atop the ductwork. They don’t take up any room and are really simple to install. Butterfly dampers are a wonderful choice if you want to use dampers for heating and cooling purposes. It is due to the fact they only depend on pressure, not the way air is flowing. Their aim is to keep the airflow moving in one direction.
Dampers for blade
Blade dampers have two blades that resemble large fans and gently close together. These dampers dampened the airflow at the point where the blades of these dampers collide. Compared to butterfly dampers, this results in a more sudden interruption of airflow, but blade dampeners also don’t care whether it’s heating or cooling season, so you can easily them in either situation.
Dampers for inlet valves
Inlet vanes dampers are similar to tiny vents that open to let air flow if dampeners are like tiny little doors that block the airflow. However, they do assist in regulating the pressure of the air traveling throughout your complete HVAC system. They do not dampen or guide your airflow.
Damper Louvers
If you want to use dampers only during the heating season, louvers dampers are a viable option for you. Louvers naturally dampen down when there is an increased pressure in an area.

Where Can I Install HVAC Dampers?
The most typical place for HVAC dampers is in the main trunk line, before and after any significant intersections. Additionally, you can install these dampers at specific locations on various system ducts, with two dampers on each main line spaced 90 degrees apart. Although dampers might differ from one manufacturer to the next and even from one unit to another, most dampers have the following features in common:
- They are spherical discs made out of heavy cardboard or thick fiberglass (similar to egg crate bedding)
- To enable or disable airflow via the damper, they contain a handle which a person can turn in either direction.
- Some dampers have a pointed metal pin for simple rotating grasp.
Every home is unique. Some houses don’t even have any dampers. Depending on where your home is located, a supply duct from your furnace may exit to the right or left. Typically, you can install a damper in the supply duct leading to your upper level. If you have exposed ducting, check each run to see if any has dampers. Some homes have dampers in each run, which is great for balancing the air.
When Should My HVAC Dampers Be Opened And Closed?
Most homes have upper level dampers that work in the summer and are idle in the winter. When the upstairs dampers are closed in the winter, heat is circulated throughout the house naturally as it rises. The lower floor is naturally cooler in the summer, yet most residents complain of overheated rooms. The dampers on the roof must be opened in the summer in order to prevent as much air from entering the basement.
Having someone go up and cover each vent with their hand is an easy way, if you have help, to check whether the dampers are open or closed. You can verify if each damper is open or closed by covering each bedroom vent with your hand. Although it requires some cooperation, it’s a great and simple method to get maximum comfort for hot and cold places in your home.
You have to alter your dampers when the weather changes. To avoid being surprised when the house becomes overheated or undercooled, it is a good idea to set an alarm on your calendar. You won’t be confused about how to adjust your dampers if you correctly identify them.
Although dampers are great, they might not be sufficient to completely eliminate hot or cold air spots in your home. You may still be experiencing issues with air balance for a number of reasons.
