When the temperature drops, most people probably leave the switch to their ceiling fan untouched, but running your fan during the winter can actually help you save on heating costs. According to Porch.com, an online home improvement network, in the winter you can make a room more comfortable by keeping your fan on low with the blades running in the reverse direction to force warmer air near the ceiling down into the room.
… How do you know if your fan is spinning in reverse? When you look up, the blades should be moving clockwise. Consult your model’s instruction manual for specific instructions, but most models have a small switch.
