All called a local fan store in my area and the sales rep told me a ceiling fan should spin counter-clockwise for summer. I know what clockwise and counter clockwise is, but looking up at a fan for some reason it can appear different from looking at a clock on the wall. I guess depending upon which blade my eye picks up on first as it's spinning, sometimes causes me to see it differently. Anyways, I saw this article and video and author's idea of lying on the floor and looking up at the ceiling fan from underneath was great.
That said, if counter-clockwise blows air downward on a fan, wouldn't that just cause the warm air to come down from the ceiling, thus defeating the purpose? So, shouldn't a fan run the opposite, especially in a stairwell leading to 2nd level bedrooms, to pull cool air from my lower level to the upstairs? Just curious, because in my case, my upstairs fans seem to work better that way.
