Where I’m at, the temps flip-flop day to day, even hour to hour. In the morning it’s 35° outside, and by evening it’s 79°. I gave up keeping up with the temps and shut my unit off for the time being.
My question is why can’t HVAC units be programmed to say that if the outside temp reaches n° and the inside temp reaches m° cold, turn on the heat; conversely, if the outside temp rises to n° and the inside temp reaches m°, then turn on the AC?
My thermostat already knows the outside and inside temp, but I still have to manually switch it back and forth. I want a system that I can just set it and forget it all year round.
My friends family has a shore house we’ve gone to a few times. It’s an old house, built before a/c was a thing, and still doesn’t have any. We throw open some windows and the house stays pretty comfortable, it’s warm but not at all unbearable even when the temps are in the 80s, 90s, occasionally even over 100 (fahrenheit of course)
It does help that it’s at the shore so there’s basically always a nice breeze.
