Installing ceiling fans in rooms without existing wiring or fixtures can be challenging but not impossible. It usually requires running new electrical wiring and installing a junction box in the ceiling. This process may involve cutting into the walls or ceiling, running the new wiring, and connecting it to a power source. It’s crucial to hire a licensed electrician for this job to ensure safety and compliance with electrical codes. Alternatively, you can explore options like battery-operated ceiling fans or using a freestanding fan instead.
