air-conditioningbasementbrick
I am looking to install a through the wall air conditioner in the basement. I don't want to block the one window. There is already a window in the brick. I don't know if there is any kind of structural issue with cutting and framing in the air conditioner.
Here is the air conditioner sleeve. LG AXSVA1

I won’t say I'm an expert; I've worked with someone doing something similar in the past and may at least give you some guidance.
Personally, I would use a concrete saw (larger blade than an angle grinder) and/or a chisel to cut the opening. Make sure you have help as you DO NOT want to drop the removed section(s). You can use these bricks later (see below).
Don't forget the header. I know I'm using the wrong term, but I'm referring to the steel plate that holds up the brick over the window.
I would then use a chisel to remove the halved bricks and either turn them around or replace them with good ones from the removed section.
I would also recommend that you at least talk with a mason. They may be able to replicate the detail work around the window with the bricks from the removed section.
Since it sounds like it might be difficult for you to get to a lumberyard to build your own solution, you might be better off using a pre-made product. AC-Safe, makes Universal Air Conditioner Supports that might be useful in your situation.
The system requires you to screw the platform into the window sill (which may or may not be possible in your situation), then simply rests against the outside of the building to support the A\C unit.
I've also seen brackets that mount to the bottom of A\C unit itself, and offer support against the outside of the building (but I was unable to find an example online. I think Thermwell makes them).

Cutting a hole in your foundation almost always requires an engineer, and is almost never a do-it-yourself project.
You'll need an engineer, to tell you how to carry the load around the opening. And you'll likely need tools and knowledge you don't have, to actually cut the hole.
