72 F / 22 C in winter and 68 F / 20 C in summer. We live in a LEED Platinum building and the electric bill for our 2-bedroom apartment never goes above $50, so we set it to whatever is most comfortable.

I try to keep between 68 F and 72 F, but uh, the thermostat's method of measuring the actual temperature in the apartment is completely, laughably busted, so... hot days it goes on 62, cold days it goes on 84.
I keep it 68F(20c) downstairs, but the main house temp is regrettably 73F(22C) and I fight to keep it that low because the rest of the house is cold blooded.
When I have my AC on (usually on the hottest summer days), I set it to 19°C (66.2°F) so it's not too cold.
I'm originally from Florida, so 78 is what I usually leave mine at during summer.
Mine is programmable. In winter it's set to 65F at night and 68F durring the day. When unoccupied it also goes to 65F. I'd love to be able to set it lower because I love the cold but my pet snake probably wouldn't appreciate it even with their hot rock and heat lamp. Durring the summer I have it set to 68F while sleeping 72F durring the day and 78F while unoccupied. I don't shut the AC off while unoccupied because in my area humidity is a much bigger issue in the summer than temperature and removing latent heat takes a long time if you let it build up all day. Currently working on refitting my system for better on demand latent heat removal.
23 all year round
I only have heat. So in the winter I usually set it to 65°F, then my wife sets it to 68°F. Then she sets it to 70°F. Then she sets it to 72°F.
By thermostat are we talking about heating? I'm cold-tolerant so I typically set mine to 15.5 C. If it gets any colder than that indoors it comes on
During the cold season
20°C, 18°C at night and when away
During the warm season
23°C, 25°C when away
When I visit the US I find that I usually set it in the mid to high 60s for optimal comfort.
Stun.
Year long lowest possible to keep whatever fluids are in the radiators flowing. Not off but not too on either. And then open windows to regulate temperature.
My building is hot OK...
As cold as the other people in the house will let me. I have rarely lived anywhere with functioning central heat and air (and have never liked it when I did), so generally I use window units and a cunningly devised system of curtains. I don't care if a hallway or the bathroom gets hot, so long as the bedroom and kitchen stay cool, y'know?
In the winter I almost never use heating, except for a small space heater I just take room to room with me, and one that I run while in the shower.
18 c - 23 c.
Summer: 77-78 during the day, 75 at night.
Winter: 70
(Not so) pro tip: Buy a stand or desk fan. What actually makes 77 feel hot is because there’s no breeze. 77 in itself is not hot. What you need is air circulation. Keeping it at 77 with a fan to get a breeze going is comfortable enough. Your electric bill will also be lower.
Ours is a variable speed compressor so during the summer, it is set to 76 during the day when my wife/kids are there and set to maintain humidity under 50% which allows overcooling by 2 degrees. We run at 70/69 at night because our youngest doesn't sleep well with the fan running in our room so I have it cooler to keep from soaking the bed with sweat.
I find roughly 80 degrees good for my sauna.
Short answer:
- 80 in summer
- 60 in winter
Long answer: It gets over 110f so we keep it at 80 in the summer. We have double pane windows, a newer ac as well. Somewhat new insulation. Otherwise the power bill is over 1000 a month. Our bill in the winter is around 100ish and mostly gas. We keep the house at 60.
PGE is terrible. It's a little more than 60c a kilowatt now...
No that's not a typo on the prices.
Yeah, that’s extremely similar to our situation. Luckily we have solar panels, so PGE doesn’t absolutely demolish our finances. We also try and open windows overnight when possible since it can be 20-30 degrees cooler.

I did some experimenting - I can't sleep above 67 at most, 65 comfortably.
Anything above 68 is too hot generally indoors and I begin to lose the ability to focus.
I don't have AC but my house is from the 1860s when people had fires running pretty much nonstop so is designed to keep cool, so even when it's 80+ outdoors the indoor temperature rarely goes above 70
Nothing. My place is so well insulated (with triple glazing) that I don't have to heat. Don't have AC, but closing the blinds during the day keeps things cool enough.

68f in the winter, and N/A for the summer (dont have AC)
AC only goes on when it's 90 out. Used it 5 times last year. People can adapt. It's like cutting sugar from your diet.
That really depends on the humidity. I can take a desert 90F or even 100F all day without AC without issue but 80F temps with a 70F dew point absolutely kills me. I lived in my area without AC for years. I never got used to it, I just stopped functioning when it got hot and muggy.
How is it like cutting sugar from your diet
It's the same thing in that both cutting sugar from your diet and living inside a 90°F/32°C box both take all possibility of joy out of your life

Humidity is a bitch here. AC keeps it at 70° F overnight and 72° F during the day. Heat won't cut on unless it's 62° F in the winter, and it runs only a couple of times over the entire season.
68, but now the weathers nice enough that I don't need to use it
69F (20.5C) year-round. Just for the memes.
It started out as ha-ha-funny-number because my college roommates kept setting the thermostat there to be funny but then it just become a comfortable temperature to exist at
72 in the winter, 69 in the summer
20°C min, 24.5°C max.
That's 68°F and 76°F in OrangeUnits.
But tbh,I don't have an AC at the moment,so the max. value is only achieved by automatic ventilation. But I has it on the same range when I was living in a country with AC.
71 in winter
70 in summer
70 in the winter. And, and we don’t have AC because most days are cool enough in the summer.
Why would I care what temperature it is when I'm sleeping? I'm asleep.
That aside, 60 winter and 73 summer.
How well do you think you would sleep at 350°?
Probably about forty minutes then baste and tent with foil and put back in for another forty.
Upstate NY - 64°F in the winter, no A/C ( just a half-assed whole house fan).
I knew upstate got cold but not that cold, damn
I set mine to 0π at night and in the summer, and ^3^/~2~π to ^11^/~6~π in the winter... the numbers have worn off and idk what the actual temp is, but I do know all of them are in Quadrant IV.
*I only open the window or curtains at night in the summer or maybe sometimes when it's raining in the winter. I think my dream house is literally a cave.
Cheap Canadian here..
18C in cold months and down to 15C at night.
Warm months I have central air but don't turn it on and just live with whatever the temp is.
I've managed to have restful sleep at 78 with two fans blasting me, plus a window open to let in the relatively cooler night air. It's doable, but the body takes time to adjust. Humidity can be a big factor.
65 in winter is kind of understandable, since you could layer up or heat a selected space or yourself easier.
My usual comfy indoor ranges would be 70 daytime, 68 night for winter, then 75 throughout in the summer.
