As is probably a pretty common problem, it's a giant pain in the ass to cool the upper floor; the main floor is fine; and the basement turns into a walk-in freezer if I leave the vents open.

The big issue aside from the whole "heat rises" thing is that the amount of air coming out of the vents in the basement is MUCH higher in the basement than the main floor and much higher on the main floor than the upper floor.

So I guess my question is just whether there are "best practices" to make the most of this. My guess is that the underlying issue isn't an easy fix. But I've been shutting the vents all the way off in the basement since it stays cool on its own. Is that a bad thing based on what you guys have been saying?
That's the same issue as differences from room-to-room which I touched on in the last paragraph. Open the vents, and leave the thermostat on the "Fan On" setting for a couple days and see if it makes a difference.
