... launched one of the most heated (and unquotable) responses I ever received from a long past girl friend when she asked "Which is the best direction for the ceiling fan to blow, up or down" and I started my response with: "Well, it depends ..." but never got any further than that.
Is there a reason?
My hypothesis is that running a fan one direction versus the other direction has little direct effect on circulation - the air moves in a toroidal shape - either upward or downward either way - the only real difference is that downward creates a direct draft/breeze, whereas upwards diffuses the draft/breeze.
You might prefer a breeze in the summer, and you might prefer no draft in the winter.
