I don't know what your unit is and what the warranty entails, but for mine (Goodman) my installer suggested 22C is a temperature not to exceed. If it's not getting cool enough on the top floor doing things like closing a few vents on the main floor and basement to push cold air to the top floor (I'd suggest buy Ecobee for the sensor vs Nest if possible so that you lose less cold air).
I apparently have 5/10 year warranty on the system, so for the first few years, I'll heed the advice.
IMO, if a home has good air flow via windows, then it's easy to pop open the windows to cool down the home after a hot day. However, certain homes (town homes especially) have exceptionally poor airflow.
