You guys have separate a/c systems for upstairs and downstairs? That must be a TX/South thing, I've never had that. We have terribly ineffective a/c on the upper floors, but it is because of the difficulty of fitting central heat/air ducts into an old house.

We have them here in so cal. I have it in my own house when we put in HVAC a few years back. It is a much more efficient system. We completely shut off the upstairs AC system when we go to bed. Our bed rooms are downstairs. Our AC is use 3-4 weeks out of the year if we are lucky. Heat is set and forget for a couple of months.
Usually is a cost issue. The AC man knows by giving the client a bid for a split system, the installation cost sky rockets. They will never get the work. It may require ripping up walls for ducts. Most of time, they just have the cost of a giant 5 ton unit and call it the day. Not acceptable to me BTW. My client and I usually have a long talk over the situation so they can make better decisions.
