Install a ceiling fan as a simple way to keep a room cool. You can lower your energy costs in the summer by running the ceiling fan alone or in conjunction with your air conditioning to make it more efficient. In addition to cooling, ceiling fans are a great way to add light to a room without needing extra space on a table or shelf like you would with a lamp. Many of these fans come with lights that switch on and off independently of the fan, allowing you to use either or both as desired. Overstock.com has a wide selection of ceiling fans to suit different types of decor. Choose a fan with wooden blades to complement a wood floor, or enjoy the more elegant look of a fan with a chandelier light fixture.
