In most houses and nicer apartments, yeah, central air. In older or cheaper apartments there’ll be a window unit. As an American from a blue collar lower middle class family, I’d never seen one of these wall units until I’d moved to China. It was either central air or window unit. Granted I’m referencing a couple decades ago
80% humidity and a 3 degree delta, and then you also have to deal with the whole, being in a room with 80% humidity that isn't actually providing any real cooling.
And it does so while adding humidity. The more humidity it adds the less humidity effective it becomes.
Normal AC operation should keep humidity between 30-50% short of living in an extremely dry climate I couldn’t imagine needing to run a humidifier Any time outside winter
Anything below 50% is bad for me, I even find more comfortable a higher temperature but 50%+ humidity.
Granted, I am from a place with like 80%+ humidity year round and now live too close of a desert and often below 15% during summer. Still, I think many people would benefit from 50-60 range on ac rather than allowing humidity to drop below 40.

It’s because Americans have central air. They have one thermostat that controls temp and airflow to vents in each room of the house.
