I'm never going to install a central A/C.
No central A/C is efficient as one that's turned off.
The big advantage is rooms where the split is off don't get heated or cooled.
Sure you can block off rooms but the system is sized to cool the whole home so when you block vents you mess with system efficiency, unless it's done on the cheap and way undersized.
I kind of like decentralized systems, that way if one fails it's not a huge household emergency.
