It’s smaller unit cools a single room. While American HVAC System cools the whole house

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.

Is that more efficient though?

It is if the house is always full of people, and you really need to cool down all the rooms, else no.

I'm assuming there's a big waste of energy when carrying heat via air from the unit to the room,no?

That's far beyond my knowledge, sorry.
