Ceiling fan installation
A fan hangs and wobbles where a light only hangs. The box holding it is the part that matters.

The short answer
Ceiling fan installation is a job for a licensed electrician when it needs a new box, new wiring or a new switch: the fan must hang from a box listed for fan support or from framing, not from an ordinary light box.
Swapping a fan onto an existing fan-rated box with working wiring is simpler; the box check is still the first step.
The box rule
NEC 314.27(C) says a box used as the sole support for a paddle fan must be listed and marked for that use, and may not support a fan over 70 pounds. Boxes for fans over 35 pounds must be marked with the weight they carry. Heavier fans are supported independently.
Recent editions also expect ceiling boxes in habitable rooms, where a fan could go, to be fan-rated or give access to framing that can take a fan brace.
What the job includes
Turning the power off, checking the existing box and replacing it with a fan-rated box or brace, assembling and hanging the fan, connecting fan and light, and balancing it.
Separate fan and light control needs an extra conductor from the switch. If it is not there, the electrician either runs new cable or uses a remote. A smart switch must be rated for fan motors.
Permit, time and what changes the price
A replacement on an existing fan-rated box is often treated as repair. A new ceiling outlet, new switch or new circuit usually needs a permit. Rules vary by city.
Price drivers: new box or brace, ceiling height and ladder or scaffold, attic access, new switch leg, fan weight and assembly time. No price ranges are published here until we hold enough sourced, dated quotes; see cost guides.
Before you buy the fan
Check ceiling height and blade clearance on the box. Downrods change the hanging height. If the room has a sloped ceiling, the fan needs a slope-rated canopy.
Fans on porches must be rated for damp or wet locations. Indoor-rated fans outdoors fail early. Check the license on your state board before anyone starts: how to check an electrician license.

Primary-source research and fact checking
We read the model code, the federal safety notice, the municipal fee sheet or the utility tariff ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. HyreElectrical does not perform, supervise or warrant electrical work. Authorship is organizational: this desk, not a named persona.

How this desk works
- Primary sources only. Code statements come from NFPA 70 as the model code. Safety statements come from CPSC. Permit fees come from the city or county fee sheet. Utility charges come from the filed tariff. We do not cite a blog that cites a source; we open the source.
- Our contractor store is five states, and 74% of it is Florida. Any figure built on that store is titled to those states and names the concentration in the first screen. It is not a national sample of electricians.
- Load calculations on this site are a published simplification in the shape of NEC 220.82 — first 10 kVA at 100%, remainder at 40%, HVAC at 100%, EVSE at 125%. They are labeled as not a stamped calculation. A licensed electrician using the adopted edition does that work.
- No national price for a panel upgrade is shipped. Labor rates, the adopted code edition, whether the utility is involved, and the state of the existing wiring move the invoice too far for a roundup to help. The cost pages publish named permit fees and the variables that move the price instead.
- We do not perform electrical work, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.

HyreElectrical is a publisher. It does not perform, supervise, inspect or warrant electrical work, holds no electrical license, and matching is still being built, so an inquiry is not a service call.
