Straightforward swap or full rough-in—calculate the complete cost to install a ceiling fan including fan grade, brace box, wiring condition, ceiling height, and new circuit if needed so your quote covers the whole job before you climb the ladder.
Standard pancake boxes and most plastic octagon boxes are rated for light fixtures only — typically 35–50 lbs static load. A ceiling fan generates dynamic load (torque and vibration) that a light box will not handle. NEC 314.27(C) requires ceiling fan boxes to be specifically listed for fan support, rated for the fan's weight and dynamic load. Installing a ceiling fan on a non-fan-rated box is a code violation and a liability. When you arrive and find a light box, the box replacement is not optional — it's required. Price it as a standard component of the job, not an upsell. A fan-rated brace box costs $12–$22 and takes 20 minutes.
Most existing ceiling light locations have a single switch leg — one cable that controls the light. To independently control the fan motor and light kit from wall switches (instead of a remote), you need a two-conductor cable to the fan plus a separate switch. If the homeowner wants separate wall control of fan and light, you're running a new wire or a wireless smart switch kit. Smart switch kits (Lutron Caseta fan controller, for example) work over existing single-wire runs — they're $80–$120 per kit but save you the wire run. Know the options before you quote; the customer who finds out on install day that separate wall control costs $200 more is not happy.
A ceiling fan on a vaulted or angled ceiling requires a ball-and-socket canopy adapter (most fans include this) and a downrod length calculated so the blades clear 7 ft above the floor — the minimum safe clearance. A fan installed too close to the ceiling on a vaulted surface wobbles and generates noise from air turbulence against the blades. Measure the pitch before quoting. Steep pitches (above 45°) may require a specialized angled mount or a different fan model. Most customers have never thought about this — you're the expert, so flag it upfront rather than discovering it on install day.

This calculator builds a quote from components: labor time by ceiling type, fan price markup, switch work, and disposal of the old fixture. Use it to price residential fan installations consistently without undercharging on high-ceiling or rewiring jobs.
