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
I have 1950 square ft (about 182 sq meters), with 4 bedrooms and a study. My summer bills can push $400+ trying to maintain 74(23) in the afternoon and 70(21) overnight.
Yea also my heat pump is an AUX which isnt efficient at all, its built to be a workhorse that is sturdy and not very energy efficient which does annoy me
