A wobbly ceiling fan is noisy and annoying, and all that extra movement may cause the hardware holding it up to work loose. Luckily, fixing the wobble is an easy DIY job, says Kennedy, who notes that blade-balancing kits are available for only a few dollars at most hardware and home-improvement stores.
Typically, the kits contain some self-adhesive weights and a clip. You simply attach the clip to the blade you think is wobbling and see if the additional weight reduces the wobble. Some trial and error will be required, but the whole process should take 30 minutes or so and require no tools other than masking tape.
