I run my AC on 68
Im in the South
Man 75 would be stuffy
I realize thermostats vary though
I have central ....3 units
But I run a small 200 dollar window unit in my bedroom
I like the hum and it gives the central unit a break
During day I put it on economy and at night its on full bore
Three summers now
In Nashville late April maybe till October
I’m in California where no one can afford to run an air conditioner on 68. That would give me a $2000 bill. No thanks.
We have the same thermostat so the difference has to be the ac.
