A/C not balanced throughout house . . hot upstairs, cold down

and cool/cold in the basement.

I completely closed the vents in the basement, slightly closed the vents
on the ground floor (where I thought was appropriate) and opened up the
critical upstairs vents (my bedroom) wide open. . . this helped a little,
but not much.

Any suggestions?

I remember reading that this could be related to attic ventilation? My
home inspector indicated that the attic ventillation on my colonial-style
house was adequate, but could be better (soffits on either end and
something that runs along the ridge line that did something else to help
ventilate). Not knowing a thing aobut attic ventilation, I went about my
merry way purchasing my home. I haven't thought about it since, but the
hot muggy nights are causing me to re-evaluate the situation.

If all the expensive options fail, a small and cheap 5k or 6k widow unit
in the bedroom will fix you right up.

That's how I solved the same problem in my wife's top floor sewing room.
She's of the hot flash age and likes the temperature set cold enough to
safely store meat and dairy.

It is true that having a separate A/C unit for each floor works better
than using only one. It is also true that you would be shocked at how
hot the attic can get with only passive ventilation. (I put a remote
thermometer in my attic without the ventilation fan running and the temp
got over 120 degrees.) I use an attic ventilation fan to keep the
temperature down because it radiates through the ceiling of the top
floor. Many will say the cost of running the fan is not wise, but I
swear by their effect.
