HVAC Dampers Guide: Everything You Need to Know

If you're looking to enhance your HVAC system's performance and energy efficiency, HVAC dampers are a must-have. Keep reading to learn more about HVAC dampers and how they can improve your system!

WHAT IS AN HVAC DAMPER? 

HVAC dampers are devices used in heating, ventilation, and air conditioning (HVAC) systems to control the flow of cool and warm air moving in ducts. They are typically installed in the ductwork and can be manually or automatically controlled. HVAC dampers work by restricting or allowing airflow, depending on the desired level of temperature or air quality.

The HVAC dampers located in your HVAC ducting affect your ability to keep your home at a comfortable temperature and humidity level. Furthermore, older dampers increase your energy consumption and bill every month.

Types of HVAC Dampers

HVAC DAMPER

There are several types of HVAC dampers available on the market. Here are some of the most common types:

  1. Volume Control Dampers (VCD): Used to regulate the air volume of individual rooms or zones in a building.

  2. Fire Dampers: These are designed to prevent the spread of fire through HVAC ducts.

  3. Smoke Dampers: Similar to fire dampers, these dampers prevent the spread of smoke through HVAC systems during a fire.

  4. Backdraft Dampers: Used to prevent the backflow of air into a room or building.

  5. Zone Dampers: These are used to control the temperature in different areas of a building, allowing for personalized comfort settings via the zoning system.

Additional HVAC Damper Features

In addition to the basic types of HVAC dampers, there are several other features and options available that can enhance their performance and functionality. Here are some of the most common additional features of HVAC dampers:

Fail-Safe: This feature ensures that the damper remains open in the event of a power outage or system failure. Fail-safe dampers are commonly used in emergency situations to ensure that ventilation and airflow remain constant.

Spring Return and Non-Spring Return: Spring return dampers use a spring to return the damper to its default position when power is cut off. Non-spring return dampers, on the other hand, rely on gravity or other mechanical means to return to their default position.

Manual and Motorized: HVAC dampers can be operated manually, by turning a hand crank or lever, or they can be motorized (automatic) dampers, using an electric or pneumatic motor to control the airflow. Motorized dampers are typically more expensive but offer more precise control and automation.

Blade Shapes: The shape of the blades on an HVAC damper can impact its performance and effectiveness. Flat blades are the most common and are suitable for most applications. However, some dampers use airfoil blades, which are curved and can provide better sealing and can control airflow more precisely.

WHY DO YOU WANT TO REPLACE A DAMPER?

Installing new HVAC dampers to replace old and ineffective ones can improve the efficiency of your heating and cooling system.

Correctly working dampers extend the longevity of your HVAC system. They allow the system to work with less effort while maintaining temperature and humidity controls. We recommend you check out our collection of dampers today.

How to Choose the Right HVAC Damper?

hvac dampers guide

Choosing the right HVAC damper for your needs can be challenging. Here are some factors to consider when making your selection:

  1. Type of Damper: Choose a damper that suits the intended purpose, such as a fire damper for fire protection or a zone damper for temperature zone control.

  2. Size: Ensure that the damper fits the size of the ductwork where it will be installed.

  3. Material: Choose a damper made from durable materials that can withstand the conditions in your HVAC system.

  4. Operating Mechanism: Consider whether you need a manual or automatic damper, depending on your preferences and needs.

Here are other important factors to consider:

MAKE SURE YOU FIND THE RIGHT SIZE HVAC DAMPER

First, choose a damper that fits the ductwork.

Make sure you use the right size for your dampers. Otherwise, you could put a lot of unnecessary stress and strain on the damper and HVAC system. By choosing the right-size dampers, the hassle, and headache disappear.

DAMPER SEALS ARE INCREDIBLY IMPORTANT

You always want a tight seal on an HVAC damper. If you need to manipulate the damper seal, it could affect the rate of warm or cool air flow into your HVAC systems. You might need to balance whether the damper is open or closed to ensure the HVAC system and ductwork function properly.

MOTOR QUALITY AND ENERGY EFFICIENCY ARE CRITICAL

The motorized system that drives your dampers is of critical importance. You need to select a high-quality motor that can work for years while making it easy to maintain the damper motor if something does go wrong.
