I don't think I know how ceiling fans work

My whole life I assumed you want the blades angled to push air down on you in the summer and opposite in the winter.

However the thought just occurred to me that hot air is always near the ceiling where the fan is so wouldn't you want to push that air down in the winter and pull the cool air up in the summer?

Would you rather lay in a pool of sweat or lay in the pool of sweat with warm breeze?

I get what you are saying.

I have AC Vents in my ceiling so when the fan is on and pushing down it should help spread the cool air around the room. I do not change the direction in the winter

When I lived in Iowa we had the vents in the floor bc you use the heater more.

In Louisiana, I never change the direction of the fan, I always want it circulating the air by pushing down on me.

It doesn't actually cool anything anyway, it just feels cooler due to evaporative cooling.

It is all about wind chill effect. You want to feel the breeze on your skin in the summer and reversing it in the winter takes away the wind chill effect and pushes the warmer air to the walls.

Here's the correct answer:

- When it's hot you turn on the ceiling fan
- When it's cold you leave the damn thing off

I didn't even know you were supposed to reverse the flow

No. You probably lived on a pier and beam foundation where they could route the ducts under the house rather than in the attic.

Or do like me and remove all of them from your house and hang lights instead.

This is the absolute reason you want the air flowing downward...

Also.. unless you have ceilings that are greater than 10' in height, running the fan in the opposite direction is pointless because generally the temp difference is negligible.

However if you do run it in the winter, the slower the fan speed the better.

Or you can spend a few more dollars and have BOTH.

It actually makes a big difference in how warm a room feels in the winter if you reverse the flow to clockwise and put it on low. I'm currently installing 7 ceiling fans in my new to me house, it's insane how big a difference they make in a room here in the south.

Install sucks when an older house wasn't build for ceiling fans and has some flimsy metal rod holding the electrical box in the ceiling, but I got that worked out now.

always remember this clever riddle for your c-fan blade direction

We only had three. The den and a couple of bedrooms. My wife and daughter don't like the fan on during the night so it was pointless to keep them. Plus the blades would collect dust since they weren't being used. We renovated the den into a master bath and put a wall up where the fan was. Just rerouted the wiring so we'd have lights over the sinks.
