What HVAC Dampers Are and What They Do

HVAC Dampers in Granite City, IL

Being able to streamline the heating and cooling system in your home to meet the unique needs of each resident might seem out of reach. For decades, central HVAC systems were only capable of creating uniform temperatures all throughout the buildings they serviced. However, just as ductless mini-split systems make it possible to customize temperature settings in individual rooms, HVAC zoning services allow homeowners with central HVAC to enjoy this level of convenience, too. HVAC dampers are an important part of HVAC zoning.

What HVAC Dampers Are

Dampers are crucial components of zoned HVAC systems. Often referred to as duct dampers, these components block the flow of air when closed. Unlike closing off air vents in spaces that aren’t being used, dampers don’t place any excessive stress on your ductwork or on any other part of your heating and cooling system. If you turn the thermostat down in a room that you aren’t using, dampers will ensure that heated air bypasses this zone and goes where it’s needed instead.

How Dampers Work

Dampers act like valves in zoned heating and cooling systems. They determine which zones require conditioned air in order to achieve the desired temperature. HVAC dampers section ductwork off in zoned configurations. They can also be installed near air distribution pipes to prevent conditioned air from entering ductwork at all. Although there are both manual and automated HVAC dampers, zoned residential HVAC systems typically use automated dampers.

Is HVAC Zoning Right for Your Home?

Zoned HVAC systems are more efficient than systems that are only capable of providing uniform heating and cooling. Although shutting HVAC air ducts is one way to direct heated or cooled air away from unoccupied spaces, this strategy doesn’t reduce energy use or home heating and cooling costs. It can also cause serious damage to HVAC systems over time. If you’re tired of spending money to heat or cool spaces that are unoccupied or if people in your home have vastly different temperature preferences or needs, scheduling an HVAC zoning service is likely the best choice.
