You won’t be able to make them budge. The reason the buildings wait it out is because they can get into big trouble if they switch it over too early and there is a late-season freeze for which their residents don’t have heat. Like gdopplerxt said, they must be able to maintain a minimum temperature in the building. I would just relax about it- it hasn’t really gotten THAT hot/humid and it cools off at night anyways. I haven’t even been running my A/C, and I have the option to. Buy a fan if you’re uncomfortable, with the low humidity that should be more than sufficient.
