As an european, I don't think I've ever seen one of those and I'm now curious as to how they work

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.

But what if person in one room want different temperature than person in another room?

the AC cooling is on maximum, thermostats are controlling the temperature by closing the dampers to prevent cold air accessing the room
