The simplified version

Summer: Day: 76°F (24°C), Night: 73°F (22°C)

Winter: Day: 78°F (25°C), Night: 73°F (22°C)

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.

72 during the day and 68 at night.

77F normally

My folks keep it at 79°F during the day and 72°F at night.

Summer - cool to 76 around the house. 68 for sleeping.

Winter - warm to 70 around the house. 65 for sleeping, with a heavier comforter.

74 in the summer and 68 in the winter. Before I met my wife I would keep it at 60 in the winter but she wasn't having it lol (heating oil is expensive). I didn't have central air so my bedroom (window unit) I'd keep at 68-70.

75 summer, 71 winter. Would love to conserve more but my body is a picky jerk.

I'd like to have it at 71f, but it's not going to happen. After a $$$ AC repair i can now get down to 74 instead of 78. Usually around 68-70 in the winter. How come it's always so hot indoors when i go to places with a cold climate?

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.

19C in the winter, around 28C in the summer. It helps that in the winter I just keep a space heater near me (I get cold and turn it on at what a thermometer in my room calls 19C).

In the summer? I have no AC at my house but it doesn't usually go above 77 - 80 on it's own. It's in a unique part of the city where we're surrounded by the woods and trees which provide a lot of shade and cool the air. Also the house is built into the side of a mountain and surrounded by massive retaining walls, so the first floor is basically a story underground. Our bedroom is also on the first floor, so I don't really go upstairs except to do laundry.

In the winter, usually about 64 - 67. It goes down to 60 during the day on a schedule or whatever.

I usually do 19C in the winter, and 24C in the summer, my parents do 22C (72F?) year around

76 in the summer and 68 in the winter

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

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

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

Winter 70-72 all the time.

75 in the summer and 68 in the winter

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

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

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.

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

Mine is set at 80 degrees during the summer. During the winter it is at 60 or maybe 65. I live in an over 100 year old dog trot style house in Alabama with only attic insulation and the original single pane double hung windows.

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

In winter I light the fire, in summer I open the windows, the temperature range goes from chilly to toasty. I don't have exact numbers on that.

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