One chore that never makes any list but one I grudgingly do every fall and then again in the spring is cleaning our ceiling fans and then reversing the direction of their rotation.
You would be amazing by the amount of dust that is perpetually spinning a few short feet above your head! Fans in some rooms usually are much more dust coated than those in other rooms, but every fan always can use a good cleaning.
As far as direction, in the winter blades should rotate in a clockwise direction. This produces a gentle updraft, which forces warm air near the ceiling down into the occupied space. There is a switch on the fan that changes the direction. Nothing could be simpler and you will feel the difference in the air flow and warmth of the room.
