Thanks for the responses, ok I have come up with a new idea here i would build 2 of these that would fit in my windown slots and connect the with 4" pipe.
you mention insulating, are the products out there for insulating 4" pipe some sort of sleeve the pipe can slide into? or can i glue some sort of thin insulation to the pipe? what do you guys think of this idea. I know what your saying about the vents being high up but, the unit has a 10x14 return grill right at the floor which i hope helps pull the heat down.
