Super easy to make an in-window unit work with horizontal windows. A single metal bar cut precisely to length holds the unit in place, then you can use a sheet of plexiglass or double wall polycarbonate to fill in the remainder of the window. You can probably get the bar cut to length at the hardware store. The double wall polycarbonate can be cut with a utility knife. Have this in two windows, works great. Portable AC's should be made illegal for how inefficient they are.

I’d you don’t seal those plastic windows in perfectly the thermal lost is pretty insane.

Still better than running a big, power-hungry machine in the enclosed space that you're trying to cool without at least letting its heat sinks stick out the window.
