Install Bedroom 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.

Just remember, electrical boxes used for ceiling lights aren’t strong enough to hold a ceiling fan. You must replace the existing electrical box with one designed for ceiling fans.

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.

Make sure electricity to circuit is turned off and carefully remove the glass shade or globe from the old light fixture.

Unscrew the retaining nut or screws that hold the fixture to the ceiling.

Lower the fixture and disconnect the wires by twisting off the plastic connectors from the ends of the wires.

Remove the old electrical box from the ceiling. If it’s nailed to a joist, pry it free with a flat bar. If it’s suspended from a bar, you may have to take off a metal plate to unscrew the box; then pry the bar from the joists.

Hold a 1/2-inch-thick pancake box against the ceiling, centered on a joist, and trace around it with a pencil.

Cut along the line with a drywall saw.

Tip: Hold a vacuum cleaner wand next to the saw to catch the dust

Feed the electrical cable coming from the ceiling through the knockout hole in the pancake box. (Be sure there’s a cable connector attached to the knockout hole.)

Set the box into the hole cut through the ceiling and press it tight against the underside of the joist.

Attach the box to the joist with the two 1 1/2-inch No. 10 hex-head screws provided. Drive in the screws with a drill/driver equipped with a 5/16-inch nut-driver tip.

Wrap the cable’s bare copper wire around the grounding screw inside the box. Allow the wire end to hang down.

Apply a small bead of urethane-based adhesive to the back of the ceiling medallion.

Pass the wires through the medallion (above).

Center the medallion on the pancake box and press. Fasten it with four 6d finishing nails driven into the joist.

Set the nailheads and fill with caulk or spackle.

Hold the fan’s metal ceiling plate up to the pancake box and pull the wires through its center hole.

Attach the ceiling plate to the box with two 1 1/2-inch-long 10-32 machine screws.

Tip: If you’re going to paint the medallion, do it before installing the ceiling plate.

With the fan on the floor, feed the wires coming from the motor through the center of the canopy. Set the canopy on top of the motor.

Next, pass the wires through the hollow down-rod pipe.

Thread the down-rod pipe into the top of the motor. Use a wrench to tighten the square-head locking screw on the side of the pipe.

Tip: The pipe’s threads have a factory-applied coating. Don’t remove this coating; it keeps the pipe from unscrewing.

Hook one side of the canopy onto the ceiling plate.

Using twist-on wire connectors, join the two green wires to the bare copper wire coming from the cable. (If your room is wired differently from the one shown here, consult a licensed electrician.)

Join the two white wires. Then connect the two black wires. Swing the fan up into position against the medallion and secure it with the two canopy screws.

Attach each fan blade to a blade iron (the bracket that holds the blade to the fan). Then, fasten the blade irons to the motor with the screws provided.

Plug the fan’s light-fixture housing into the wire hanging from the underside of the fan’s motor.

Install the shades and lightbulbs.

Screw the plastic holder for the remote control to the wall beside the wall switch.
