Which direction should ceiling fan turn in summer?
Keeping this in consideration, does ceiling fan direction really matter?
It's important to note, ceiling fans don't change the temperature of the air, but the blowing air can feel cool. When it's cold outside, changing your ceiling fan rotation to clockwise can help you feel warmer. The blades spinning in this direction pull cool air up.
Correspondingly, do Ceiling fans help air conditioning?
According to Energy.gov, “If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.” If you turn on your ceiling fans, turn your air conditioner up 4 degrees to 80 degrees. The ceiling fan will keep you just as cool, at a reduced cost.
It changes the direction of the blade rotation. In the winter, you actually want that switch in the up position, and in the summer, it should be in the down position as shown above. In the cooler months, having the blades circulating in a clockwise direction will create an updraft.
