@StampedingLonghorn @StarTracker I gotta say that I honestly don't buy the whole "ceiling vents are better for cooling" thing because it gets pretty dang hot here, too, yet nobody seems to complain that the vents are in the floor.
I mean, they're forcing air out of them at a decent clip and air seems to mix fine. Plus ceiling fans help even further.
Regardless, you can have them overhead but also not in the attic! Just have to learn to live with a partially dropped ceiling
