Ceiling fans cool you, not the room. They don't remove humidity, but they're generally inexpensive to buy and run, whether you use them alone or with air conditioning. And with a little help, you can install one yourself. A 52-inch-diameter fan is ideal for rooms that are 225 to 400 square feet. Pick a 42- to 44-inch fan for 144 to 225 square feet. If your room size is on the border, choose a larger fan and run it on a slower speed.
The higher the cubic feet per minute, the more air movement, but don't sweat small differences. Ceiling fans with the most airflow were the noisiest in our tests, although it was wind noise and fluttering, not a whirring motor. And fans with blades that have ridges, bumps, or other surface texture were often noisier on high than those with smooth blades.
