gave you a very good way to check the systems effectiveness . Do
that, and let us know. Keep in mind, that, if you have alot of heat
generating equipment in your apartment, then you may have increased
the cooling load beyond what the system is capable of .

So, if its 100f outside best I can hope for is 80?

What I used to get was 70 no problems. What if its 70 outside
shouldn't the air conditon get to 60 or less?

I think the PP meant to say that "an air conditioning system should
provide an indoor environment supply temperature of approx. 15-20 F
lower than the indoor return temperature at the time 'if' it is
properly sized and functioning correctly."
