A landlord once told me that I should only expect thirty degrees of cooling compared to the outside. The first thing to check is that the air filter is clean. Another easy thing to add is a portable dehumidifier. Just a little bit more effort, and you can put in a ceiling fan--which helps still the air from floor vents.

These guys say that if your A/C does superb on the hottest days, then that system is actually too powerful (and expensive) for all the average days. This would mean that the hottest days need help beyond using the A/C (no cooking, using clothes dryer, closing closets, etc.) https://www.cleartheairac.com/hvac/running-your-ac-when-its-100-degrees-outside/

This discussion has some checklists, and a diagnostic that I assume your HVAC guys can check: There is a point where it gets so hot outside that air conditioners simply can't do anything to get rid of the heat (the outdoor coil temp equals the outdoor air temp) (Most A/C units will have specs on this. You can try looking up some specs for it online.)
