During the winter, it's hard to say. I live in an old apt, and don't pay for heat, so even if you cranked it all the way up, it still stops at a certain point. Which is still too warm for me! And my thermostat only shows numbers, spaced out, without any lines inbetween. If I had to guess, I'd say I keep it in the upper 60's, low 70's, but at night it goes down, and the window is opened. I hate sleeping in warm rooms. I still play musical thermostat since sometimes i'm cold for no reason, turn up the heat, then roasting. i just can't seem to get it at a comfy temp.
in the summer, I have two thru-the-wall A/c units. one in the LR, which has a dial for higher cool, and lower cool. I'd say its somewhere in the upper 60's, as I like it arctic.
the one in my bedroom I put in, and it has a digital read. During the day when I'm not home its at 74, but at night, i crank it down to 66. But the actual temp never gets taht low, maybe 68 or 69.
My elderly neighbor downstairs used to get on my case about leaving my a/c on all day, until I finally told her a. it actually keeps it cooler so when I get home, sometiems after TWO jobs, it doesn't take all night to cool down, and b. when she starts paying my electricc bill, she can dictate how I do things. But we have that kind of relationship where I can tell her to quit it, and vice versa.
When I visit my mom, it can be problematic, as she is older, and feels the cold more. I loved her old house as it had dual zone heat and a/c, so I'd crank it up for me, and she could keep it comfy for her. And when she moved, as her house was still under construction, I begged her to have them put wiring for a ceiling fan in the second bedroom (didn't normally come with it) knowing temp would be an issue. SOOOOO glad I did as it really does help.
