Depends on how wet your room is which will depend on ambient as well as how full the room is with plants.
AC normally good for maybe 20% off ambient. So if it is a soggy mess A/C alone won't do.
I like to drop my humidity as flowering progress, I'd take 40% if I could get it that low. They did say the sensor on my unit was funky too and replaced, but I'm alas, still waiting.
