Answer
Installing a ceiling fan where a light fixture already exists is a weekend afternoon project. The existing wiring (hot, neutral, ground) connects directly to the fan, no new wiring required.
Before you start: check the box
Most ceiling electrical boxes are rated for light fixtures only — not the weight and motion of a fan. The box must be fan-rated (usually stamped "acceptable for fan support" or has a metal brace). If the existing box wobbles or is a plastic box, replace it with a fan-rated metal box ($10–15) before hanging the fan.
Turn off the power
Turn off the breaker for the light circuit. Verify with a non-contact voltage tester before touching any wires.
Assembly
Most fans assemble on the ground: attach the mounting bracket to the box, assemble the motor housing, attach the blades to blade brackets, and attach blade brackets to the motor. Read the specific instructions — they vary by brand.
Wiring a fan with one wall switch
You'll have three fan wires (black, white, green/bare) and three ceiling wires (black, white, green/bare). Connect black to black (hot), white to white (neutral), green or bare to green/bare (ground). The fan motor and light kit share the same switched hot — the pull chains on the fan control the light and speed separately.
Wiring a fan with two switches (fan and light separately)
The ceiling must have two hot wires (typically black and blue) plus neutral and ground. Connect the blue wire (light) to the fan's blue/light wire. Connect the black wire (fan motor) to the fan's black wire. This allows independent wall switch control of fan and light.
Balancing
If the fan wobbles after installation: first tighten all blade brackets and blade screws. If still unbalanced, use the balancing kit (usually included) — a small weight clip that slides along the blade to correct imbalance.
