After going through a bunch different contractors trying to get splits installed, I just put in a dedicated circuit for all my PC equipment in my office and put one of these in the window for the summer:
Amazon product ASIN B08677DCKN
Pretty unique design, very quiet for a window unit. However, they really only work with modern Anderson-style windows, which works for me because I recently stripped the old windows down to the openings, built new sills/trim etc out with Azek and replaced them with modern windows.
