We have a three story (plus also basement) house.

During hot weather, the upper floors are very considerably warmer
than the bottom floors. That's because, drumroll, hot air tends to
rise up.

The issue, in my mind, is that air does not circulate sufficiently. It
would seem to me that the answer is to somehow suck air from the third
floor into where it is picked up by A/C for cooling, or just to
improve the speed of air circulation in general.

Are there any standard approaches to analyzing this problem. I would
prefer to fully understand the issues involves before making a
decision to hire any outside help.

thanks
