installing AC over window

plschwartz

I have a 24 inch window on the end wall in a frame house.
I want to place a 150 lb aircon over the window.
I assume that the window was boxed out.
But as I will be taking the rest of the stud out is there anything special I should do?
Thank you

What stud? What are you going to do about the header above the window? What load is above the window? One story house or two story house?

Thanks Joe for answering
This is a one story frame built house. From the look of things I assume that the end wall has 2x4 studs every 16 inches. Since the window is ~24 inches wide the center stud has been cut out and the area framed out with a header etc.
Then I assume cripple stud from header to rafter.
It is in the space above the header where I want to put an 18000btu AC ~150 lbs.
I assume that I will have to frame out the AC opening in a manner similar to that for the window.
I hesitate to put the AC directly on the sill plate because of the weight.
Is there any special consideration needed in making the AC frame?
Since the top of the AC frame be within a foot of the rafter do I need a header?
Thank you

What is the ceiling height? Sounds like a high ceiling.....or low height window. Regardless.....no matter what you do ...you need a header above the air conditioner. Those cripples are what hold up the roof.

yes, you will want a header above whatever opening you cut out of the wall just like you see above the window. if you transfer the header load from above the window to the top plate then you could take the window header out that is there now ( or set your unit on it) and work your ac unit into that space, just keep all headers above all openings.
