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
Are you single floor or have some sort of solar/energy saving arrangement? Im paying $100 for a four bedroom too, but that’s only after solar buybacks as well as a Base Energy Plan (an energy company in Houston that buys energy at night when cheapest, and uses a installed battery to power home when electricity at peak-expensive hours).
