Does it *really* matter? Either you're pushing air down the center of
the room and causing it to rise up the walls, or you're pulling air up
the center of the room and causing it to fall down the walls.
Besides, I can't reach the direction switch on the one in my living
room. I have a 5' ladder and a 14' ceiling.
I only run mine in the summer, so I have them set in down direction
too. That is the way you definitely want them set in the summer, as
it gives a direct breeze. In winter, the theory is that you save
energy by moving the heated air at the ceiling down along the side
walls. However, I've never seen any real techinical analysis that
says it amount to anything significant, or even that it's a positive
effect. In fact, I think by moving the air you could just be
accelerating the heat loss.
Blowing down will make people feel cooler -- good in summer.
In the winter, you probably want it blowing upwards -- but
maybe you don't need to run it at all during winter. And it
don't matter which way it's blowing if it ain't blowin'.

A difference which makes no difference is no difference. If you can't
tell don't worry about it.
BTW, thinking of ladders, I recently saw a neighbor using a chain saw
on a tree, while standing near the top pf a wobbly 16-foot ladder.
That looked a lot scarier than any of the Halloween stuff.
And speaking of chain saws and trees, one of the scariest injuries I
ever saw when working in the ER was the hunter who tried to climb into
his tree stand with a running chain saw. I have no idea what was so
urgent that he couldn't wait to start the saw until he got up
