That way you get a draft to cool you off more in the summer and avoid such in the winter. I even noticed that switch before but never thought about what it might do...
A friendly reminder: dust off the fan blades before you switch directions. I forgot to do this last week and dumped dust all over my bedspread right as I was about to get under it.
The winter feature is to circulate the warm air that accumulates at the ceiling back down.
Either way the air is going to mix up and equalize. It makes little difference unless your rooms are massive
It doesn't affect the temperature. It mixes the air just as well either way. The difference is whether you get a constant stream of air blowing down on you or if it comes down dissipated on the outside of the room.
And I actually sometimes leave it blowing upwards in summer, because cold air falls and hot air rises, so circulating air from the A/C upwards to the hot ceiling seems to be more effective at keeping the whole room cool.
Yeah I think OP has it reversed; in the summer you want to pull cool air up and in the winter you want to blow hot air down
Honestly it's mostly just going to move air around either way. It's not like hot air is going to collect above it while it's still going, nor cold below.
It's just a matter of whether you want direct airflow or indirect.
I think having it blow upward during summer depends on if you have A/C to begin with because, without that, having a downward breeze is a relief even if it’s lukewarm, and during winter can also be a judgement call, but the downward breeze could be uncomfortably chilling for some.
Are you sure? It's been a very common feature for a very long time.

Some have a third pull cord, others have a toggle switch between the light and fan, but there are some that just don't have reverse at all.
