i finally got myself a thru the wall air conditioner yesterday and i need a
sleeve for it and was going to order a factory one but i wonder if i cant
just make one myself?

a wood box my unit can slide into with a mesh grill on the end for the heat
exhaust should work?

i would cut the hole in my wall and frame it around this wood box, have a
pair of heavy duty metal shelf brackets on outer wall holding up the box.
slide my unit into it and screw it to the base of the box to lock it in. install
a mesh guard on the outside end and paint the whole thing and caulk all
around it after it dries?

has anyone else made their own A/C sleeve? if so, how about some pictures?
