How to put a window ac in a wall.

Measure the height of the wall opening and subtract the combined thickness of the 2 x 4 s you just cut. Window air conditioners often come with a foam insulating strip. With the insulation removed mark the opening corners by drilling through the exterior sheeting with a long drill bit. Strictly speaking if you put a window unit in the wall it won t be vented correctly and it can overheat and die or have a shorter lifespan.

Put those four pieces of 2 x 4 lumber together to make a frame. Use the level to ensure it is level and hammer it into place with nails into the opposing studs. In the 3 8 c channel insert nut rod coupling on the end. Measure your a c from left to right including your frame.

Drill hole on the side through channel and coupling than insert a screw. Measure a 2 by 4 and saw it to fit on top of the cut vertical wall studs at the bottom of the hole. Cut the strip of foam to the correct length and insert it between the upper window sash and the lower window sash. Do prepare the window and install brackets if necessary.

Before installing a window ac open the window as far as it goes remove the screen and clean the windowsill glass and window frame. Extend the accordion panels from both sides of the air conditioner to the window sash track. Cut two pieces of the c channel in both sizes1 2 and 3 8. Then cut those down to the matching lengths.

Secure the side panels with screws.
