Question

How do i cut a hole in the wall for an air conditioner to go in?

Answer 1

find the wall studs, make the opening 1/2 larger than the a/c case.

Answer 2

cutting the hole is the easy part. mark out the hole by measuring the unit then transfer the layout to the wall. use a drywall saw on the interior to cut JUST the drywall. now you can see if you have wiring and/or plumbing to reroute. the last thing you want to do is hit a live electrical line or a water pipe with a sawsaz. after you move things around then get out the sawsaz and cut the studs. use scrap 2X4's, cut them to fit in between the stud cavities, put them in flush to the cut drywall and s***w through the drywall into the wood. you dont really need to s***w or nail in to the studs, this is just to cover the openings its not a header. use a drill and drill a hole in all 4 corners through the siding. then outside use a straight edge and mark out the opening. use a circular saw set to just slightly deeper than the siding is thick. slide the unit in and make sure that you run a bead of clear silicone around the opening to make a good seal. now you have to flash the outside and i recommend using a tube of Black Jack to seal the opening between the A/C unit and the opening. its made for roofing and will remain tacky and be able to expand and contract with the weather.

Room air conditioners are available for installation in double-hung and casement windows. Mark the opening on the inside wall....
