4 ways to quiet a noisy attic ceiling fan.
Attic vent making noise.
Blade is made of thin metal sheets in most of the household fans.
The vent hood ducts through a rigid or flexible pipe to a cap on the roof or side of your home.
If the fan makes a constant metal clanking noise in all probability the fan blades are imbalanced.
Often a stiff wind will open vent dampers causing them to periodically clang shut.
Attic fans rattling and shaking are quite common and it s a problem faced by many homeowners who have fans.
Air passing through ducts and radiators can sometimes create a loud noise as can water passing through pipes.
Replace the fan itself.
If the noise drives you crazy new spring loaded backdraft dampers 9 to 30 depending on the size should solve the problem.
If you have a closed off attic open a window at the other end or install one to solve this problem.
If so the rotating blade will create some noise and the airflow outcome won t be as expected also.
This is something that.
This happens when the fan doesn t receive enough air.
A loose attic vent or shutter on a window can make a banging noise in the wind.
Due to excessive pressure or sudden strikes these blades might get bent or damaged.
Heating ducts as they cool also make banging noises as do.
When you hear a banging coming from the attic and are trying to determine the cause you are most likely dealing with one of these four animals.
