Thanks for the personal experiences - very helpful. We don't have a written quote yet, but the brands mentioned to my husband weren't ones I had heard before. I don't think we have the needed "install expertise" but maybe we can assist.
We are also hoping to add a minisplit in the room we are shifting out workout equipment into in our house. That room is only about 14x19 with tall ceilings. Mainly looking for added cooling as it is climate controlled.
