What's the best way to install a window air unit into a 42" window in
a vintage apartment? Should I get some plywood pieces cut to fill the
gap between the unit and the window pane, or is there some other way
that is better?

Thanks.

Probably need more info for folks to reply.

If it falls, where will it go, aka, what will it hit? Wood frame, metal
frame? If it's of any size and the window is in in poor shape could it pull
the window out? Maybe ask the super for CYA?
