Fix for a clanging vent hood damper.
Q Every time the wind kicks up, it opens the damper on my kitchen vent hood. When the wind dies down, the damper slams shut, making a metallic "clang." The noise drives me crazy. What's the fix?
A New spring-loaded backdraft dampers ($9 to $30, depending on the size) should solve the problem. Measure the diameter of the vent pipe and order the dampers from a duct supply company (hvacquick.com is one source). Start by replacing the backdraft damper directly above the vent hood. If that doesn't solve the problem, install a second damper near the wall or roof discharge cap. The second damper will greatly reduce the clanging problem.
