I would say that either you made a typo or or the problem is your AC is not big enough. Five ton for 25K feet??????
I have 1400 square living space feet and I have a 3 1/2 ton.
If you have really 25K and only a five ton, you need some zone cooling and more Compressors.
Then realize that a HVAC unit will only cool so many degrees off the outside temp. You could have had high humidity, or other factors.
