Besides looking like low-speed airplane propellers hanging dangerously close to my head, they seem like an awful lot of trouble for not a lot of cooling.
For starters, there's the ceiling fan wobble they all seem to have. That's where when they're set on high speed, the entire fan - post and all - wobbles side to side violently. All you can do is wait for it to come flying off the ceiling and into whatever or whoever is waiting below.
Then there's the what-switch-does-what conundrum. There's usually a low speed, a high speed and the on/off for the light. But it seems however many times you pull the cord or flip the switch, you never quite land on the setting you're looking for.
Finally, there's the basic style of the fan. If you're going for the Kenny Rogers gambler card room look, or old west whorehouse decor, then ceiling fans might just do the trick. But for anything really contemporary, they're not going to cut it (pun intended). It doesn't matter what materials the blades are made of or what color. Ceiling fans are inherently items that all look like they came from a western saloon in the 1800's.
When it comes to cooling off the Ponderosa, I'll stick with our central air conditioning. Sure it sounds like a C-130 taking off, and definitely isn't the most energy efficient system. But damn if I don't need a sweater to stay warm when it's on to cool the house down.
Besides, I have kids. I don't want to take the chance of this happening:
