When sleeping, normally 68. During the day it can vary a little depending on what the weather outside is doing and if we’ve just come inside from extra hot or cold weather. We’ve got a mini split heat pump though, so typically we’re only running the inverter in whatever room(s) we’re in rather than keeping all the units on at a consistent temp.
Lately we've been trying to "pre-cool" a little in the mornings so that the house can slowly heat up during the day without the AC going full blast all afternoon. It's working okay, but not perfectly. We still struggle to keep the upstairs bedrooms cool enough (76 or below) without overcooling the downstairs (72). The AC is usually set somewhere in the middle (74ish).
My upstairs used to run about ten degrees hotter until I installed a booster fan in the duct to pull cool basement air up there. I know they're generally ill-advised for most scenarios, but it works incredibly well for me in summer since it would have been a very expensive proposition to upsize the vent, install a return, or put in a mini-split.
