It's 90 deg. outside, humidity is 37%. The A/C is set to 80 deg. The
temp in the apartment is at 83 deg, and hasn't gone below that. The A/
C has been running non-stop for hours. The temp out of the vents is
colder than the air in the apartment, but not a lot colder. (I don't
have a thermometer.)

Running for hours could mean anything more than one hour. There's not
much information there. Let it run overnight. If it can't bring the apartment
down to temperature overnight, then there's something definitely wrong
with it.
