I thought about this some more, and I have a thought and a suggestion.
For anyone with two air conditioners: it would be advisable to only use one unit whenever you can. Why? Because too much capacity means cooling down the 'dwelling' too fast, which means not enough dehumidification is taking place. The result is a cold, clammy environment that leads to people pushing down the thermostat, but that only briefly fixes the problem, if it fixes it all all. So then, push the thermostat down some more . . . and soon, you're living in sub-70 degree surroundings and you're STILL not comfortable.
Too high humidity is potentially a very damaging situation, to you as well as your dwelling. Get a humidity gage. They are cheap. Walmart probably has one for less than $10. If the humidity is regularly above 50% then this would be a good place to address your attention. If it's above 60% regularly, you've got a problem, you are inviting mold. Once mold gets started, then you must get humidity down and keep it down, as that is the only effective method of controlling mold. Better to not let it get started.
Most people are very comfortable at 74 to 76 degrees if the humidity is 50% or less. Most people can't get comfortable at any temperature if the humidity is above 70%, and they usually have respiratory issues . . . for some odd reason.
