They can be used year-round. In the winter, ceiling fans equipped with reverse switches can take hot air and pull it down from the ceiling. Bedrooms are the most common areas for ceiling fans, followed by dining and living rooms. Check the warranty on the motor and the degree of blade pitch, which determines how much air is moved. Ceiling fans should not wobble when installed.
Portable fans remain the most expeditious solution to tepid temperatures.
They're selling faster than we can put them out. It's cheaper than running your air conditioner. The DWP figures a circulating fan costs 1 cent an hour to run, compared with a 3-ton central air conditioner, which can cost 55 cents per hour to run. Oscillating fans, floor fans and other air-circulating fans can be effective when used alone or in combination with an air conditioner, Krigger said. Portable fans can be used to draw in cool night air.
