Where Are Dampers Located?
Dampers are located inside duct work, which can often be found in attics or crawlspaces. It may be necessary to follow a duct from the furnace to find the damper. In addition to those found within ducts, dampers for adjusting air flow can be found on indoor air registers.
Dampers are valves that control air flow and affect the temperature in a home. A homeowner attempting to significantly change the inside temperature may need to locate dampers, adjust them and test the corresponding air intakes within the house. Adjusting the rate of air flow in ducts can help eliminate temperature disparities between rooms in a home.
