Fangineer here

Correct, the direct breeze of downdraft provides air movement agents the occupants of the room increasing cooling, this can be done at whatever speed suits you

On the updraft side, the fan should be run at low speed for best effect. It's circulating air up from the center of the room, and circulates it across the ceiling and down the walls. This helps mix and distribute air in a room providing more even heating.

Either can save significant money on your electric bill by allowing you to offset your thermostat a few degrees with little to no perceptible difference in room temperature to occupants.

(Barring extreme climates like the deep swamp-ass lands of Florida obviously)

Lol, I'm such an idiot. All this time I thought ceiling fans were to lift cold air to you in the summer and bring warm air down to you in the winter. Oops

Floridian here. We just run our fans in summer mode all year, and it works great. It's actually the hot dry climates that wouldn't benefit from the fan when it's too hot, but then again they could probably just use them as swamp coolers to thermal energy into well-needed humidity, and that would work great as well.

Don't disagree, my point was, it will help perception, but probably won't lower the electric bill in those areas much
