As long as the perceived temperature is below skin temperature, yes. But when it goes above and when humidity is high no fan can help you..

(It's a bit more complicated than that, but basically when you can't

You do need ceilings of a certain height. I live in an old farmhouse and the ceilings are just too low.

I agree that they're great if ceiling height supports them.

Even if you have 8-9 foot ceilings, consider a low profile ceiling fan rather than the sort that hangs down a foot or more.

My bedroom's just over 7 feet. Old New England farmhouse :-) So a ceiling fan doesn't really work even above the bed because I'm the tall person who will get nicked by it.

Why not? I've had one for years - they work very well.

Why not yet? Cost/effort for the so far relatively short amount of time it would be used. However that amount of time is increasing it seems.

Installing a ceiling fan is a pretty easy DIY project if the room already has an overhead light fixture. They can regularly be bought for less than $100 in many chain stores as well.
