With a typical fan, run the fan counter-clockwise in the summer, and in the winter, run the fan clockwise at a low speed.
In the summer, blow the air down to directly cool you. If you have a large room, and you are on the outside of the room, you may want to run the fan in the opposite direction.
In the winter, blow the air up on slow to pull the cool air up, mixing the cool air with the warm air at the ceiling, and pushing the air across the ceiling to the walls, then coming down the walls, and minimizing wind chill.
I've seen a lot of opinions and theories on this question and really I don't think it matters. The fan should adequately circulate the air in either direction, producing a more uniform temperature throughout the room.
But personal preference for most of us says that in the summer we want the fan blowing down, so we get the draft directly from the fan, and in the winter we want the fan blowing up, so we are not chilled by the draft.
when looking up at the fan it should turn counter clockwise
The rotation of a ceiling fan should move air down in the summertime and up in the wintertime. As for the position of the switch hard to say as to how it is wired.
A ceiling fan should move air downwards in the summer time and upwards in the winter time.
Reverse direction of the fan. Move air down in summer of breeze, and up in winter for circulation
The string activates a switch in the fan.
In this way, the shadow of the fan rotating at the floor is clockwise. Ceiling fans can be set up to rotate either way, many of them have a switch that will change the direction. Others can be wired to rotate either way. Typically they are designed to push air rather than pull it.
Ceiling fans are a good idea because they help to circulate air. In the summer they can be adjusted to circulate the room air down. In the winter they can be adjusted to circulate the room air up.
Not all fans do that. Some are also reversible. Also the direction of turning is opposite if you observe from the opposite side.A bit more:On ceiling fans, they are made to be reversed for a reason, so the blades can either pull the air up or push it down. For example, on mine, with the way the blades are tilted, when it goes clockwise, it pulls the air up, pulling the warmer air upwards. When I flip the switch to reverse the direction to counter clockwise, the blades push the air downwards.For home ceiling fans, the air should be moving down in the summer time. In the winter time when the home heating unit is being used, the air should be drawn up to the ceiling. This causes a flow pattern that circulates up through the fan to the ceiling, across the ceiling and down the walls to the floor where it gets drawn back up to the ceiling. This rotational pattern draws the warm air from the ceiling and redistributes it to the floor where you can sense the warmth.
down
Reverse direction of the fan. Move air down in summer of breeze, and up in winter for circulation
up in the summer and down in the winter
Counter Clockwise. Push air down (down position on most fans)
down for the summer and up for winter
----------- According to ehow.com: In theory, the updraft can aid heating. The premise is that it pulls cool air up to the ceiling, where most of the heated air settles, and then sends warmer air down into the room along the outer walls. Most fans come with a discreet switch to reverse the direction the motor turns the fan blades. This is a vertical slide switch with two positions. Generally the down position will cause the fan to blow downward and the up position will create an updraft. http://www.ehow.com/how_4895488_reverse-ceiling-fan-blades.html
In winter, fan should blow down,heat rises,get it back. In summer ,fan should blow up for a 2 story vaulted ceiling,to circulate air but not blow down hot air.On a one story in summer it can blow either,but it's a prefference.Up is ok,but down you get a lower cool index feeling.
For summer use, the airflow should go down directly from the fan to the floor. For winter use it should pull the air from the floor towards the ceiling so it flows across the ceiling and around the room. So as to whether it should be clock-wise or counter clock-wise, that would depend on the angle of your blades. It's best to just stand under it when it's on. In the summer you should feel the air blowing on you from the fan and in the winter you shouldn't.
Paint the ceiling first. Work top down.

Three feet from the ceiling will give a good circulation of air from above the fan. Remember in the summer time the fan blows the air down, in the winter time the fan draws the air up.
