Wife sets thermostat hot and I open the window behind our bed and crank a fan. Seems to work for us so far. Probably adds something to the bill since the thermo for that heat pump is in our room.

Heck, I looked out the bathroom window for something and apparently there’s no lock. No big deal I’ve no idea if we even have keys for the house we bought 4 years ago and with glass sliders everywhere on all levels it wouldn’t matter. More important, the window was open 4” and must’ve been since we moved in or something. Never open those blinds myself.
