The fan has been sitting in the garage for two years. Two summers of a hot bedroom, because "electrical work" sounds like a job for somebody else. If you're swapping an existing light for a fan, it probably isn't.

You can swap an existing ceiling light for a ceiling fan using the electrical box and wiring that's already there, as long as that box is rated for a fan. The fan costs $80-$300. A lot of service calls cost $100 to $150 just for the guy to show up.
One homeowner put this off for two years because it sounded like an electrician job. The wiring took eleven minutes. The other two hours went to assembling the fan and getting it up the ladder alone.
Once the old light is down, look at the metal box in the ceiling. It must say it is rated for a fan. Not rated? Stop and call an electrician. A fan hung from a standard light-duty box can eventually fall. That's the single most common and most serious mistake.

Always kill the breaker, not just the switch. The second big mistake is skipping the voltage test and assuming the switch being off means the wires are dead. Touch the voltage tester to the wires before you touch anything. It must show no power. And never skip the ground wire.
If your ceiling doesn't already have an electrical box in the right spot, if you need to run new wiring or a new switch, or if the box's rating is unclear, have an electrician confirm the box before you hang anything from it.

Can I replace a light fixture with a ceiling fan myself?
Yes, if you use the box and wiring already there and the box is rated for a fan. It's covered by most homeowner exemptions.
How do I know if my ceiling box can hold a fan?
Take the old light down and look at the metal box. It must say it is rated for a fan. If it doesn't, or the rating is unclear, stop and have an electrician confirm it.
Is turning off the wall switch enough?
No. Turn off the breaker, then touch a voltage tester to the wires. It must show no power.
How much does a ceiling fan cost?
The fan typically costs $80-$300.
When should I call an electrician?
If there's no box in the right spot, you need new wiring or a new switch, or the box's fan rating is missing or unclear.
