Beat the Heat: Install a Ceiling Fan
The popularity of ceiling fans continues to grow as more and more homeowners discover dramatic, year-round energy savings. In summer, ceiling fans create cooling breezes, which reduce the strain on air conditioners. In winter, they circulate heated air to keep the room warm. Installing a ceiling fan is relatively simple, especially if the space above is accessible from an attic. However, even when it isn’t, the job is still quite doable. Here, we’ll show how to replace an old light fixture with a new ceiling fan and light, in a room with no attic above. The advantage of this approach is that you don’t have to run new wiring. The fan connects to the existing cable from the old light.
There are few fixtures that can impact the look and livability of a room as much as a ceiling fan. It can keep you cool on sultry summer days, push warm air down into the room during winter, and even serve as the room’s primary illumination if you add a light. The best news: Replacing an existing light fixture with a fan is a simple, one-day task since the wiring is already in place.
However—and this is very important—you can’t just hang the fan from the existing electrical box. It’s simply not strong enough to support the added weight and vibration of a fan. Presuming you don’t have access to the ceiling fan from above, you must either use a specially rated hanger and box to mount the fan between joists or, better yet, screw a fan-rated “pancake” box (so called because it’s very thin) directly to a ceiling joist.
