Now that cooler weather is settling in; should I change the direction of my ceiling fan?
Yes, change the direction. In summer you want it blowing down, so the people in the room feel the draft. In winter you want it blowing up, to take cool air from the floor and push it up the the ceiling where it will displace the warm that collects there without making a draft that people can feel. And run it on the lowest speed. If done correctly I am told it makes the room feel warmer without using more heat. The idea is to keep the room air mixed without making enough of a draft to feel. In summer you want to feel the cool draft, so you run the fan at high speed and blowing down on the people in the room. In winter you switch it to blow up at a low speed; just barely enough to keep the air from stratifying into a warm layer at the ceiling and a cool layer at the floor. But I have never actually tried it myself. I just don’t use the fans in winter.
