For the at-home solution, I'd remove the fan, place it so the
axle is parallel to the ground, and spin the fan blade by hand.
When it comes to a stop, mark the top (highest point) of the
fan blade an indelible marker. Do this a few times; the fan
should come to rest at the same spot each time.

Add weight to the top (marked spot), and repeat.  Eventually,
the fan blade will stop at different spots each time, which
should mean it is balanced.

Or, get lucky and swap out the old one, which hopefully is
balanced.
