Ceiling fans are a money-saving addition to a room: using the fan during both winter and summer can lower your heating and cooling costs, and a ceiling fan that also has a light fixture means that you will more than likely not need to purchase additional light fixtures for that room.
We have had ceiling fans in nearly every room in both of the homes we have purchased. (We've only ever owned one home at a time.) In the first home we purchased, almost all of the fans needed to be replaced, and we found nice Hunter fans on clearance. They served us well, being both attractive and functional.
Our current home had no ceiling fan or light fixture in the living room, which we found rather odd. We ended up purchasing two nice standing floor lamps for $10 apiece, and they have solved our lighting problems. We still have not installed a ceiling fan, and we really need to do that. No-name or Casablanca fans, it really doesn't matter to me what brand we buy. I just want a decent and sturdy fan at a cheap price.
How often do you use your ceiling fans?
