We had all sorts of minor issues with the system in our old home over the years, most of them were due to incorrectly setup draining.

Not quite. An oversized unit would cool the space faster than it can remove humidity. You'd end up with a cold humid space. Would go back to what Redbeard was talking about with short cycling.

BTW, In my old house my (by old I mean age. I still live here) 2nd floor will be a bit colder than the first floor. I sized the ductwork to the second floor to handle cooling load. I have to shut the registers off almost completely in the winter.
