Why is my floor fan so loud?
A problem common to both types of fans is excessive noise. Accumulated dirt can cause noise because it can unbalance fan blades and wear out bearings. After every two weeks of use, vacuum a fan with a crevice-cleaning attachment. At least twice during the summer, wipe dirt from the blades with a damp sponge.
