Whole-house centralized variable speed heat-pump with zones is actually the most efficient way to heat/cool your home. Also better at circulating air, filtering, dehumidifying, etc.

HVAC companies push multiple mini-splits these days because they're faster to install, and have better margins, even though they're technically not the best solution versus centralized air.

So if i already have duct work from an old AC I can use that duct work for something like this Mitsubishi Zuba?

The Mitsubishi Zuba system is a good example of this type.
