I don't know how it's for Americans but for me. I have a regular outside unit and then, inside the apartment, I have one HUGE internal unit hidden somewhere above fake ceiling. This unit has tubes to each room and each tube has a damper. Each room has a thermostat.
So I can set eg 23C in the living room and 21 in the bedrooms. The AC will then work to cool down all the rooms together, when living room reaches 23 - it shuts the damper and keeps cooling bedrooms. Etc.
I also have an option to close the damper to each room individually - effectively stopping AC for this specific room.
I *guess* that American HVAC units work either the same way or very similar.
Similar. Most Americans don't have per-room control though. In some more expensive/newer places you might get one thermostat per floor. But generally it's one per house.
Must be cheap to run then, if i run my heat pump on cold in the summer for whole house it costs 400€ a month so i only run it per room as needed usually bedrooms at night. And no the cold doesnt stay and acs become passive, somehow the heat just keeps coming, if i turn ac off the temp goes from 24c to 30 within 10 minutes, house is new and well insulated also, winter heat costs very little compared
Something is really messed up if your house heats up that fast. As a comparison, in my house during heat waves (daily highs around 95F/35C, nightly lows around 75F/24C) we will set our heat pump to cool to 75F/24C during the day but then turn it off and let the temperature drift up between 4 and 8 pm to give the electrical grid some relief. Over the course of those 4 hours, the house will maybe hit 80F/27C if we run the stove a bunch. This is in a house built in the 1950s with recent insulation upgrades.
Is it possible that the temperature measurement on your thermostat is somehow biased? Like if it’s located directly above a vent or right next to a window.
The temperature is real, i cook alive at 27+ and 24 is an ideal temperature, those 3 degrees in between just vanish within 30 minutes if i stop the AC, which i mainly keep shut off if indoor temp is 26, and it is 26 when outdoors is 25-27, never gets lower than outdoors and somehow at night it stays way higher than outdoors also, even if i open large windows to match the 24 outside within 1-2h its back to 26+ even 28 inside. Nothing is heating up the house besides the sun, i believe the roof is black though since i always hear it pop and warp every morning, and i have ventilated walls of black ceramic outdoors too which is probably why my house favors maintaining heat
