They cool people effectively by introducing slow movement into the otherwise still, hot air of a room.Fans never actually cool air, unlike air-conditioning equipment, they in fact heat the air due to the waste heat from the motor and friction, but use significantly less power (cooling air is thermodynamically expensive).Throughout the 1980s, the balance of sales between American-made ceiling fans and those imported from manufacturers in India, Taiwan, Hong Kong and eventually China changed dramatically with imported fans taking the lion's share of the market by the late 1980s. S-made fans sold for 0 to 0, while the most expensive imported fans rarely exceeded 0.Since 2000, important inroads have been made by companies such as Monte Carlo, Minka Aire, Quorum, Craftmade, Litex and Fanimation - offering higher price ceiling fans with more decorative value.Through the 1980s and 1990s, ceiling fans remained popular in the United States.Many small American importers, most of them rather short-lived, started importing ceiling fans.

Ceiling fans typically rotate more slowly than other types of circulating fans, such as electric desk fans.

The electrically powered ceiling fan was invented in 1882 by Philip Diehl.

He had engineered the electric motor used in the first electrically powered Singer sewing machines, and in 1882 he adapted that motor for use in a ceiling-mounted fan.

Some ceiling fans can only blow air in one direction and are not reversible in any way, more often downdraft only, but rarely updraft only.

It's the case on most antique fans, and most industrial fans.

Some ceiling fans, mostly Hunter ones made in or before 1984, are mechanically reversible (have adjustable blade pitch) instead of an electrically reversible motor.
