Fans in Summer - Counterclockwise
Fans in Winter - Clockwise
"Ceiling fans cool people (not rooms). In hot weather, operate the fan in the normal [counter-clockwise] direction. This creates a cooling 'wind chill' effect to make you feel up to 9 degrees cooler. Research has shown that you can then raise the thermostat setting, resutling in reduced air conditioning energy consumption of 40% or more. Remember: operating fan in empty rooms just waste energy , so turn it off when you leave the room.
In cold weather, operate the fan in the slow speed, Reverse direction (clockwise). This creates a gentle updraft which recirculates the hot air trapped at the ceiling to provide even, comfortable heat throughout your room. The re-circulation of warm air allows you to lower the room's thermostat setting, resulting in energy savings of 10% or more."
OK, so I had some fans going one way and some another, and I had to look it up. I can still explain FX hedges without research. So there.
