The plan is to place the unit on the roof of the condo where our compressor currently resides.

I would keep the furnace for super cold days and use the heat pump portion of the mini split for milder cold days.

They say you lose 30% of efficiency just in your conventional duct work alone. The mini split delivers the hot/cold directly where it is needed. I think that is a huge deal. Especially in house like mine where the ducts are located in an unconditioned crawl space.

Yes, the draw back is the inside units on the walls. They do make ceiling register type units but that adds to the cost - and demolition if you don't have access to the ceiling from above.
