Don't know where OP lives, but in S AL we try to space turning on heat or AC at least 24 hours away from opening windows. But this week we heat the house with heat pump at night, then with open windows/outside air from about 11 am until 5 pm when outside hits 70 but we're still 60 inside, then heat pump again if it's clear and going to drop below 40 again.
