In my experience you can keep the rooms somewhat cool just but closing the curtains. If they are shaded they don’t collect that much heat. The AC only has to run for couple minutes for them to be nicely cool. If the room gets really hot (I once ranted an attic that was like an oven during the summer) it’s hard to keep it a bit cool. Either the AC is running constantly or it gets really hot.
