Minnesota, USA here.
DH and I tend to run cold, and we like being warm, so our house is a bit warmer than some! We have forced air heating and air conditioning, gas furnace and electrical a/c.
In the summer, our a/c is set for 82F when we're gone, and 78F when we're home. I wouldn't even turn it on most days, except for the humidity here makes it feel so much warmer than it really is. Summer temps are typically around 80-85F but there are days when it gets up into the 90F range.
In the winter, our furnace is set for 65F when we're gone, and 70F when we're home. It might go down to 68F after like 10 pm or so, when we're in bed. Average winter temps are like 10-25F, but it routinely gets as cold as -20F in January and February. I would be afraid of our pipes freezing if we set our temps any lower!
