Sounds like your A/C unit is too small for the area you are trying to cool.
It shouldn't have to run constantly in order to keep the cooled area at 72.

A properly sized ac will run pretty much continuously when the temp is
in the high 90s. A larger unit would not run enough during more
moderate outdoor temps resulting in high indoor humidity making it
feel clammy. You want a unit that is just big enough to hande the
area but not bigger. It's perfectly normal to size one such that it
can't keep up when the outdoor temp is unusually high. And the wear
on them is actually less if they run for longer periods rather than
startng and stopping a lot. Startup is hard on the compressors
because they start in a loaded condition, the refrigerant is already
near or above 100 psi when not running.
