Those are very sensible suggestions tbf; it's just that my house is really small! I live alone, renting. My room upstairs doesn't fit any more than my bed and the AC (floor unit). The only way I can work up there is with a laptop on my bed, which is an ergonomic nightmare that will have me cramping in about 10 minutes.

I have a small sofa that is comfortable enough to sleep on downstairs, that I would probably use if I did not have the AC

I can lug the AC up and down the stairs but one of those 2 areas will be so warm that by the time I've moved it I'm immediately in need of another shower... and then again when I move it back.
