I live in a campervan and so have no temperature control in the traditional sense. Closest thing would be the Maxxfan with thermostatic fan control and it's set to 68F. As long as external temps are lower than internal temps it does a reasonable job.

Currently set to 67F (19.4C) for heating, and I don't have air conditioning but would probably keep it around 76F (24C).The weather here is mild enough that we usually don't need AC in summer.

We're starting to have more and more hot days during summer though, so I'm getting the gas furnace replaced with a heat pump HVAC (which is the term Americans use for a reverse cycle air conditioner) this week. The furnace is 22 years old so it was due for a replacement anyways. I had an 11.2kW solar system installed earlier this year, so I'm trying to move away from gas appliances.

I have an evaporative cooler it really doesn't have temperature control. It is kind of whatever the outside temperature is -20f degrees with 75% humidity.

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

WTF 70s? I'd be roasting.

69 is usually what I keep it at in my car.

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.

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.

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'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.

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

Summer time 20C (68F)

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

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 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.

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

Usually 72° F / 22.22°C. But my wife likes to turn it down on the really hot days were the AC doesn’t quite keep up. I try to explain the AC is running all out, turning it down does not help. And we certainly do not have one of the high end units that can throttle, it is either on or off.

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

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

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
