The Environmental Protection Agency says that ceiling fans are a fabulous alternative to air conditioning and can reduce or eliminate the need for air conditioning. Ceiling fans cool a person using the wind chill factor instead of modifying the temperature or humidity of the air in the room. As such they consume less energy than an air conditioner.
Those who are handy with appliances and have a basic knowledge of electrical appliances can easily install a ceiling fan on their own. However, it is best to take proper precautions before you begin installation to avoid a short circuit or fire.
