Though we don't sit down and make a list or anything, we find ourselves naturally doing more seasonal cleaning- washing the curtains, cleaning the windows, and replacing the heater filter. We replace our shower liner, wash our pillows, and give away any of last season's clothes that won't be worn again. It's just makes sense to do these things now during the transition.
Real Simple has a nice checklist (as they often do), incase you want to create your own Fall cleaning routine.
AT Chicago also had a nice list last year.
