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

Our heater is set to 60F in the winter.

If i want it warmer than that (usually) it's up to me to keep the wood stove fired and fed!

I program mine to run less when we're not home. On top of that I set a "super cool" routine on weekends when it's going to be hot outside.

You see, the a/c is most efficient when it's cooler already. So in the last hour of darkness in the summer I set it to run down to 68 or so. Then it doesn't have to run as long to do that. Then it doesn't have to run again for several hours as the temperature is set back to 72.

I also clean the outside coils annually and put up a sun sail so that the outside unit is shaded all day. This has helped save a lot of money along with the thermostat programming.

74F during the day, 72F at bed time.

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.

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

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.

I do 26c, my partner likes 24c.

We don't have a set temperature for all year, that seems silly to me. The outside temperature, the price of electricity/gas, the energy efficient of your house, so many variables...

Apologies for not converting, but in the winter we stick to the mid to high 60s when it's in the 40s or below outside. For the summer if it's getting into the high 90s or low 100s we have to go up to the high 70s to avoid going broke on electricity.

PS go clean out the heat exchange fins on your compressor outside, sometimes animals or weather will clog them up with debris which kills the efficiency of the compressor.

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

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

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

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

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

86F/30C. Turn on the fan and it's cool

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.

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.

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

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
