During the summer months a ceiling fan should be blowing straight down (blades turning counter-clockwise) to help cool you off via a wind chill effect. Fan speed should be on medium or high.
During the winter months the fan speed should be set to low and reversed (blades turning clockwise) to help draw room air up towards the ceiling and force the warm air out and down.
A ceiling fan is just like a light, it won’t do you much good if you are not in the room so make sure you turn it off if you are leaving the room for any length of time.
