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...

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.
