I installed a customer supplied ceiling fan in the center of the guest bedroom. I installed a fan brace box and ran a 14-3 wire from the new box to the existing switch box. I removed the single gang new work switch box and installed a 2 gang old work box and wired it so the existing switch leg for the room turned on a lamp due to the fact the fan does not have a light. And the black from the 14-3 to the other switch and that control the power to the fan. Tested the fan and the switches. Customer has a 30 day warranty
