Ceiling Fan / April 24, 2018 / Glenna Gillespie
If you're among the fortunate, the room will have a ceiling box that is being used for a light fixture already mounted in the center of the room. Generally, the existing ceiling box will need to be replaced with one specifically designed for mounting a ceiling fan. Ceiling fans weigh considerably more than light fixtures and may require additional support. If the material that came with the fan doesn't include a new ceiling box and mounting brackets, you will have to purchase these separately before proceeding. You may need to hire an experienced, licensed electrician to do this part of the job if you don't have the expertise yourself. The primary consideration is to make certain that the ceiling box provides adequate support for the weight of the ceiling fan. A brace (mounting bracket) mounted between ceilings joists will provide the necessary support.
Before recently, to control your ceiling fan and the lighting on that fan from a switch, you needed a three-conductor wire in between the switch and the wall. Now some fan manufacturers make controls that will allow you to wire up with your existing two-conductor wires. And even more, pretty much all fan-and-light combinations on the market can be packaged with a remote control that only needs two wires at the ceiling box to give it power.
