Help installing a window AC thru the wall

its just like installing any window, you need to make sure you install a load bearing header first, leave enought room to freely slide the unit in, and out then trim it from the out side. I usally layout the hole on the inside of the room, then I cut the drywall, then cut out the studs and unstall a header and jacks. you might need to go a little larger to go from stud to stud, but thats all right on the inside just don’t cut the hole on the out side that big. Now that you have a header installed, frame in your opening to the size of your unit, then use a long drill bit to drill hole to the outside corners. the I go outside and cut the siding, I normally do this with a circular saw with a plywood blade and I install the blade backward, it will cut the vinyl siding by fiction and not grab it just go slow, or you can use a razor knife or some sheet metal cutters what ever you are comfortable with, after you have the siding cut thru you need to cut the sheathing with a saws all. You can use J mold to trim the siding. I would give myself enough room to try to use some type of seal for the AC to set on. on the in side just patch the drywall trim out the opening with some trim and your in in business. keep in mind window units only last so long and your next one more that likely will be a different size so having a bigger header installed saves the trouble of redoing that job in a few years when you put a bigger unit in or hopefully they will get smaller. hope some this helps.

make sure that you install it as far from where you make dust as possible. You also may want to consider doing something extra to pre-filter the air so that you don’t have to change the air conditioner filter every other minute.

I built a little support for mine out of 2×4 and then I attacked the wall with my reciprocating saw. Sealed with Great Stuff from a can. G H E T T O but very functional.

Make sure to slope the unit a liitle towards the outside so the condenste will drain outdoors.
