Why most of the ceiling fans turns from left to right ?

There is a switch on most ceiling fans that I have seen that will allow you to change which direction the blades rotate. I believe when they're going clockwise it pushes air down, and counter-clockwise it pulls the air up, or vice versa as I can't remember which is which off the top of my head. LOL!

You may find if you look a bit closer that the fan may have a button or a flip switch that actually changes the direction of the rotation of the blade. It is usually located on the casing where the motor is housed. Make sure if you want to change the setting that you turn the fan off before changing the direction by flipping the switch or button. One direction is to bring the warm air down from the ceiling. This setting is good to use in the winter when the room gets cold easily. The other direction is for the summer time when the room gets too hot and you want the cool air to circulate. I'm not sure which direction is which but a manual of your particular fan on line may help or just experimenting with it.

mab be cuz it cant turn frm right to left.... heeeeeeeeeee heeeeeeeee...
