Seems to me our Hunter ceiling fans allow you to set which way the blades rotate -- and that one direction is good for Summer (moving hot air up?) and one for Winter (moving hot air down).
1. Which way is which?
2. Does it really make much difference?
3. If you have the a/c on, does that alter the case?
Haven't put the downstairs unit in yet, and so far so good -- but if there's any way to enhance air flow, I'm there. We have ceiling fans in most rooms. |

Our electrician said it doesn't really make a difference - the air moves - who cares which way. It must have been a marketing ploy by the fan companies to sell fans in the winter.
What does make a difference is keeping the room as cool as possible. That means keeping the shades drawn if you get alot of sun. Our Maplewood room is unbearable in the summer if we keep the curtains open on the west side.
We do have our fan on in the bedroom when we have the a/c on -we keep both on low - and again - it's the air movement that cools you off. |

Cynicalgirl,
Here's what Bob Villa says:

You had it backwards.

Thanks to both of you. I do shut the curtains upstairs by day (no shades). Downstairs, most windows have bamboo/matchstick blinds and curtains -- the blinds seem to be doing a decent job of letting air in but keeping light out.
Jersey_Boy, that answers it then. Appreciate the link. |

Simple physics. The higher edge of the blade leads for downward air in summer, and the lower edge leads for updraft in the winter. Yes it does make a difference, especially if you're in the room since the cool breeze touches the skin.
It is sometimes confusing to determine if a fan is turning clockwise or counterclockwise since it is a matter of perspective.
Look for a fan that has atleast a 15% blade angle. |

I've got a laundromat with a 12' ceiling. If I create downward air movement won't I just be blowing the hot air which has risen to the ceiling down toward the floor? |

Or will you be blowing the cooler air that's down low up and around the room? Six to one, half dozen to another--in this case I think.
I was going to say what Bob Vila says. That's pretty much what I thought too. |
