Ceiling fan direction
Most ceiling fans are designed to be reversible, that is the blades spin
in both directions at the flip of a switch. This feature was introduced
to market the use of ceiling fans in the winter.
A ceiling fan fan serves two primary purposes: to provide a cooling
breeze, and to circulate the air throughout a room or area. The first
purpose is used primarily in hot weather but circulation can assist with
heating as well as cooling. However you likely do NOT want to feel a
cooling breeze in the winter. So the idea was introduced to run the fan
in updraft instead of downdraft, blowing up towards the ceiling. This
way air is circulated throughout the room without a breeze.
99% of ceiling fans currently in use run clockwise in "reverse" (updraft
or winter mode) and counter-clockwise for regular operation. If you
are not sure about your fan, run it on high and stand directly under the
blades. If you do not feel a breeze, reverse the fan. When you feel
the strongest breeze, that is downdraft or "forward" for summer operation.
Some fans do not have the reverse feature. Don't worry, you can still
use your fan to circulate heat in the winter without a draft. See
"Ceiling Fan FAQ" for more information on ceiling fan operation.
