21 in summer, though it hardly ever kicks in with the awesome isolation we have.

23 in winter, cause I like it toasty.

21oC in winter, off in summer. I ain't going to waste energy when you can just close the window if you are cold.

I don't have aircon either, not that I would be able to afford it even if I did have it.

Oh and the thermostat lies anyway and is actually just on or off so. 30 minutes in the morning and 1 hour in the evening. Well except last winter where I decided food was more important than warmth and just turned it on when necissary to keep the place habitable.

We're in Canada so we use Celsius but I'll convert for our farenheit friends:

23C/73.4F most of the time we try to keep the heat/AC off in spring/fall when it makes sense to do so.... We seem to generate a lot of heat inside (we have a lot of computers in the house) so it has to be quite a bit cooler outside to justify opening windows. something like 16C/60F, then between the heat from everything inside and the cold outside, we tend to keep rather comfortable.

My last place was an apartment and we didn't have control over the heating. Whenever it was on, we were cooking, so we left all the windows open all winter (the super knew about the situation and recommended we do this). The valves for the baseboard heaters were extremely old, didn't have knobs, and the super said he could try to adjust them, but there's a decent chance that they could snap and flood the apartment. Nobody wanted that, so we just left the windows open. For summer, I only turned on our AC at the apartment after the haters shut off. I wasn't going to pay to run AC to cool the place down while they were actively heating it up.... I'm glad we don't live there anymore because of that, though, everything else about the place was stellar. The landlord tried to get the owner to Green light the replacement of the valves while the system was not in use (namely in summer when they turned it off) since it would be easy to drain the system and do the work, but they didn't, so year after year, Windows open in winter. It kinda sucked, but we did what we had to. I installed a netatmo temperature system and at times in the dead of winter with all the windows open, the inside temps would read in excess of 30C/86F which wasn't fun. Hanging around in boxers with all the windows open in the dead of winter, and still sweating by doing nothing at all, wasn't great.

My new place has it's problems with airflow, but it's much better overall.

Just moved into a house with ac for the first time and it is well insulated and lots of shade from trees. At night before bed I set it to 68, and in the morning I set it to 74. Even when we had 100 degree days it never got above 73 inside, so basically I only run the AC at night.

Chiming in to say comparing thermostat settings between houses is comparing apples to oranges. Your AC is only "on" or "off," changing the thermostat setting only changes how much time it's on vs how much time it's off.

On a 100° day, the HVAC in a well-insulated house with double paned windows and solid weatherization is going to be able to maintain 77° with little effort, where a poorly insulated, leaky house may struggle to even reach 77° with the HVAC running continuously. These two houses may have their thermostats set the same but their internal temperatures and energy usage will be different, maybe even radically different

76F in the summer, 72F during the day in the winter, 68F at night in the winter.

25.5 C (78F) in the summer, 21 C (71F) in the winter

Cincinnati. 66 at night 70 during the day during the summer, sometimes 72.

Winter 70-72 all the time.

I like to keep my home at 16°C (60.8°F) when possible. Summers are hell.

65° while I sleep, 68°-70° while I'm home, off while I'm not

68-75. This means if it's between those numbers, the HVAC doesn't turn on.

I don't have AC and haven't really needed it this year. I'm way north in New Hampshire.

We keep the heat at 63-65f(about 17c) in the winter, but occasionally go up to 67 when it's warmer out and the furnace doesn't have to work as hard to keep it there.

I don't! My windows are open all year here in Chicago.

75 in the summer and 68 in the winter

For A/C I like it warmer than most office buildings, around 27°C/81°F, which means it's usually off outside of summer heat waves. My current place in Vancouver has no A/C.

Winter the heater's usually at 21°C/70°F.

Summer time 20C (68F)

I'm in Denver Summer: 80° in the day, 70° at night Winter: 73° in the day, 63° at night

Minimum, but it still doesn't get below 23C in the winter

There is no one right temperature — it depends on the humidity. In the winter I often have heat at 71. In the summer 68.

In the summer 78F during the day but I spend most of that time in the basement because that's where my office is and 68F at night to sleep.

During the winter 68F all day err' day

stays on 73F year round , AC and heat. Average bill runs around $80.
