The quality of the equipment, how frequently you run your HVAC unit, and if you follow regular maintenance schedules can all affect the lifespan of your HVAC components. Dampers can last around 20 years with proper maintenance.
Depending on use, dampers need to be replaced every 1-3 years.
If one of your dampers isn't functioning, an HVAC damper replacement costs about $350. Call a local duct installer for an estimate.
Flip the damper into an open position and inspect the registers once more to see if airflow begins. You probably have a bad damper if, when the damper is closed, you feel limited airflow or none at all.
The first enemy is common to all wear items – time. At about 500,000 miles, silicone tends to harden. The harder the silicone, the less functional the damper. The second cause of failure is droppage.
One of the earliest signs the damper needs attention is if it's difficult to open and close. This could indicate rust, corrosion, or warping caused by moisture or heat. These issues can prevent the damper from making a proper seal when closed, allowing heat to escape.

Butterfly flat dish dampers are the most common type of damper in HVAC systems. They're often used in residential and commercial air conditioning systems as well as in heating ducts. The butterfly flat dish damper is shaped like a circle with two semicircles attached to it.
Dampers typically run over $200 (sometimes more). It should take less than an hour to replace it but the plumber will probably also charge you for his time tracking one down and picking it up so you could expect to pay an additional $150 to $200 in labor.
It depends on the specific dampers you have and general usage conditions. However, the average butterfly damper should last about 20 years as long as you remember to clean and maintain your system. Electric dampers may only last about 15 years before the motor starts to experience problems.
The primary benefit of using an HVAC damper is that it helps to conserve energy by allowing you to restrict airflow in certain parts of your home where it isn't needed. By regulating the flow of air, you can better maintain desired temperatures and reduce the amount of energy used throughout your home.
In 2021 the University of Maryland released a report on the Reliability of Fire Dampers, Smoke Dampers and Smoke Control Systems. 53% of dampers in existing buildings needed repairs.
A heating or cooling system is a significant investment, and it only makes sense to get as much use out of it as possible. In general, most HVAC systems will last 15 to 25 years, but depending on the type of system and other contributing factors, that estimate can be highly variable.
If you have someone to assist you, one simple method to see whether the dampers are open or closed is to have someone go up and cover each vent with their hand. By covering a bedroom's vent with your hand, you may check each damper to ensure it is open or shut.
A motorized damper regulates the flow of air inside your HVAC system, which in turn controls the temperature in your home. If your damper isn't working, you'll need to replace the part. Expect to pay an average of $350 to replace a motorized HVAC damper, with a typical range of $250 to $450.
A damper is usually placed near the end of each duct run and has three positions: closed, half-open, and fully open. The closed position blocks airflow completely, while the half-open allows only partial airflow. The fully open position allows maximum airflow out of the ductwork.
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.” Instead, have a pro measure the static pressure to see if you can safely adjust your dampers. If you can't, consider one of the alternative solutions.
The components within a shock absorber are made of metal, rubber and plastic, all of which eventually degrade through extended use, extreme heat, and adverse road and weather conditions.
The damper surfaces should be cleaned to prevent hindrance to airflow. Make sure that parts such as linkage, bearings, blades, etc. that are intended to move freely, can do so. Lubricating these components can prevent possible rusting and unnecessary friction increase.
Obstruction is one of the most common factors contributing to damper failure. Obstruction can be caused by something as minor as dust build-up or as significant as another trade installing its materials through damper openings.
How Long Do Dampers Last? The quality of the equipment, how frequently you run your HVAC unit, and whether you follow regular maintenance schedules can all affect the lifespan of your HVAC components. With proper maintenance, dampers can last around 20 years.
Fire dampers need to be inspected and tested 1 year after the initial acceptance test and then every 4 years, unless the dampers are installed in a hospital, in which case they can be inspected and tested every 6 years.
If the device is stuck in one position or won't fully close and open, there could be an issue with the controls or mechanism. Sticking, opening and closing problems often arise from corrosion, rust and structural issues. A professional repair company can help restore proper function to your fire damper.
