Per Does running a dehumidifier with an AC unit save money?, I understand that while a house is occupied, it doesn't make sense to run both an AC unit at normalish temperatures (maybe 75), and a dehumidifier.
Elsewhere, I have read that if you are going on vacation, you should run your AC unit full blast for a couple hours and then bump it to something like 85 for the rest of the day. The couple of on hours help to dehumidify, while you save money for the other hours of the day. For example.
I am wondering if it makes sense to have a dehumidifier running all the time while I just leave my AC at 85, say.
