Thanks Tom for the insight.

I wasn't thinking of them as a better alternative to the roof units. I was thinking more in line of the mini split being a replacement for basement airs. And in that situation, adapting the mini split to work with existing basement air.

If my basement air was not repairable (hard to imagine after looking at it), then I would have to think really hard about taking a Sawzall to the roof :-) My first thoughts would be to cobble together a fix for what I have.
