: wall cutout?
I don't know. That is more a question for a home contractor (someone that does home renovations or construction) than about an appliance which this web site is about and my own personal experience is with. Load bearing wall considerations are likely necessary as well as possibly building permits.
You can read some instructions at the page linked below.
: I would like to install a window unit through the wall.
Most window air conditioners have side air louvers which are required for proper operation. In many cases the walls of a house are thick enough that they'd block off those side louvers (depending on the actual design of air conditioner and house). ANY reduction in their air movement will reduce cooling ability, increase energy consumption and likely lead to premature component failure of the fan motor ($$$), compressor ($$$+) or both.
Air conditioners designed to be mounted through the wall both intake and exhaust air through the rear so wall thinkness is not a problem. They are also usually designed to be mounted into sleeves so they can be easily removed for service which should be done at least every 3 years. Failure to properly maintain an air conditioner will reduce cooling ability, increase energy consumption and likely lead to premature component failure of the fan motor ($$$), compressor ($$$+) or both.
However you go about it, I *strongly* suggest you make it so the unit can be *easily* removed afterward for service. But make sure it isn't an easy access point for burglars.
