Looking for some recommendations on mini split sizing. Attached is a layout of our new garage. It has a 22'x28' space and a 14'x32' space that are connected. I am looking to heat and cool the garage portion only, the shop will be separate. The ceiling is R49 and the walls are R23.5 and sheetrocked/taped. I'd like to do it with one wall mounted unit if at all possible on the 32ft wall. Climate will see -5* to 105*. Thinking a 24k unit should suffice? Planning on doing a Mr.Cool DIY. Thanks.
