Yeah, but a window mounted unit is good enough. Keeps your whole place cool. It sounds like everybody has their windows open anyway, and this way you can store them or sell them when you don't need it anymore.
A lot of landlords & HOAs disallow window units. They also can compromise your home security
So dystopian. "No you can't put a magic cooling box in your window even though it will solve all your problems, because I say so."
