“OK…so the most common technical question that people ask regarding ceiling fans is “What direction should my fan spin during the summer and winter” and “Why?”
Quick Answer: I say quick answer, because this is a very generalized answer, which in many (or most) cases is not necessarily correct. But, I will state this answer first simply because it is what has been the industry wide answer for over 100 years.
“During the summer you want the fan to blow air straight down, so your ceiling fan needs to run in a counter clockwise direction (as you look up at it). The warmer it is, the higher the speed should be. During the winter, your fan should run at a low speed in a clockwise direction.”
