We bought a CT house, that only has "crank out" windows. The prior
owner had installed central air, which is no longer repairable (per 2
service visits).

I would like to AC our bedroom - no real need for the rest of our
house. Is there any Air Conditioner, that I could use / adapt to our
crank out BR windows?

Note: I do not want to spend $$, to replace our central AC unit. We
only want AC, when sleeping.
