Thanks for the discussion. Very helpful and appreciated.
yep. no basement here. House has about forty inches of clearance from bottom of joists to dirt . Continuous concrete foundation and footers, with vents in the concrete that I seal up in the winter. Far from 100percent airtight, but the place breathes nicely and no condensation underneath due in large part to heavy plastic as a vapor barrier on the dirt.
They are the most efficient and no problems with backup heat (none needed unless you're far north). Our ductless runs off the generator when power is out. They're also utterly quiet outside. You only hear the fan running inside, about the same as fast speed from normal duct discharge.

I reckon with ducts already in my house here in GA, I'll just stay with American kind of heat pump. Thinking of mini split in separate office building.
You want to know where the future is going? The ability to connect traditional American ducted systems with mini splits with the SAME outdoor unit. At this point, one US owned manufacturer is already working on this for the last year. Close, but not out yet. Personally, I can't wait.

Hopefully, My unit will be here in the next few weeks and I can get it installed
So split duct mounted units on main branches with all refrigerant lines connected and to the outdoor unit? Would one recover from another? That would be interesting on a retrofit basis.
Would those mini splits be ducted? What would the air handler do if there were mini splits installed?You have a 20 year old ducted system that needs to be replaced.
Contractor comes in and replaces air handler or gas furnace/coil, along with outdoor unit, and then can add indoor mini splits off the same outdoor unit.
