Two floors - one cool the other is not
The fans spinning outside are not the same fans that circulate cool air through the ducts but all fans are needed.
Can you find the two pipes, one fat (perhaps one inch) and one skinny (perhaps 3/8 inch) going into the attic unit that serves the upstairs and connecting to the unit outdoors? If the fat pipe is quite warm just as it exits the unit, you may have a low freon or other deficiency in the AC unit that needs attention.
There should be an air filter somewhere in the ducts or the body for each AC unit inside. With no filter, the innards of the unit, which include closely spaced razor sharp fins similar to baseboard radiators, will become clogged with dust.
A lot of condensation means the unit is fundamentally working although not necessarily most efficiently.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
