I just looked, and there is a large A/C vent under each front seat. So while there is no 'direct connection', it does draw the air from those vents up into the seats. Maybe those who experience less than frosty cold air prefer the a/c setting on manual, with 100% of the a/c blowing through the upper vents, while those who leave it on auto (or the feet level setting?) get a quick burst of cold air. Something to consider.
