Hi,

I own a house in PA.

On most days, only the attic bedrooms need A/C.

The attic bedrooms have space b/w the "knee wall" and the roof (where it
says I:

/__\
/| |\
/I| |I\

That's my best diagram ever.

Anyway, I would like to stick an A/C in that space. I envision that
it'll spit the hot air out through a duct that will exist via a soffit.
The cold air will enter the wall through the knee wall.

My basic question is this: are there A/C units with 4" or 6" I/O? If
not, is there a different workable solution?

Thanks!

Sam

There are portable AC units that have what amount to large diameter
flexible hoses that look a lot like a clothes dryer vent hose. You
can set one up to be permanent. Look at the dual hose unit on this
site, one hose takes in outside air through the condenser then out
it goes through the other hose exhausting the hot air. Hoses can be
extended.
