Thermostat settings

The AC at work[1] has public-access thermostats. As I've been thinking about my own carbon footprint lately, I've been paying attention to what those thermostats are set to. They all seem to be set rather cold -- mostly in the 71-73[2] range, but on a few occasions, I've seen as low as 68. I try to keep the one near me at 75, but occasionally people set it lower.

At home, I also have central AC. When I'm not home, it's shut off. When I am home, it's set to 78. If it's cool enough outside, I shut off the AC, open up some windows, and set a fan to try to get air circulating through them.

Do you have an air conditioner? If so, is it central or room? And either way, where do you have the thermostat[3] set?

[1] Nominally central, but in actuality a bunch of separately controlled units with a 40+ year age span.
[2] All temperatures are in degrees Fahrenheit. It's what they're all instrumented in, and what I most easily think in.
[3] I'm assuming your room AC, if that's the case, has a thermostat, instead of a "more cool/less cool" control.

We have room-ish AC: ductless minisplits. One big one for the dining room/living room on the 1st floor, room-specific ones for our workrooms, bedroom, and guestroom. If we turn them all on, the effect resembles central AC, carrying over to most of the house (save the sunporch).

All units are off by default. When turned on, they tend to get set in the 75-78 range. (Once I set mine to 80 during a heat wave.) Occasionally I'll set the downstairs one as low as 72 if I'm having a lot of people in the dining room playing games; AFAICT, "72 at unit" == "75-76 at people".

One of the many lovely things about minisplits is that they don't use up windows, so even in rooms with only one window when the weather cools off we can just open the window instead.
