The multi-split units that can run 3-5 indoor units per outdoor are more common in whole-house retrofit projects. They're not as efficient as the 1:1 mini splits because the outdoor units can't ramp down as far, but they're still quite good. We have two systems, each consisting of an outdoor unit, a 'branch box' in the basement, and 4 indoor wall units. 8 separate outdoor units would be insane.Isn't it a thing nowadays that if you have issues with ducting, you go the "mini-split" route. Instead of having one central unit that pipes the air to each room (and associated returns), you end up with a unit in each room (or placed into key rooms). They install it on the wall up high, and there is an associated outdoor unit for each one. It is widely used outside the US and claimed to be more efficient. One problem is for people with HOAs, it can be difficult to get approval to install those outdoor units on the opposite sides of the walls, tending to have rules in place that force you to put your main outdoor AC unit in the back of the house.
