Through the wall A/C with sleeve.

I wish to install a through the wall A/C unit.

My question relates to the sleeve.

My home is a wood frame home with press board siding on the exterior and drywall on the interior.

I intend to purchase an LG 8,000 BTU unit with sleeve. The sleeve shown is for exterior protection of the A/C unit and screws to the siding.

I have a separate 15 A circuit for the A/C unit.

Question #1:

Is there an actual through the wall sleeve? Or is the A/C unit just mounted in the boxed out 2x4 wall opening?

Question #2:

Does the A/C unit itself act as the flange to cover the interior drywall opening? Or should I plan to trim the interior opening myself?

Thank you,

Yes you will need to get the sleeve. The sleeve is what holds the unit. Yes you will need to trim the sleeve. 1/4 round, trim etc etc are commonly used.

Or you can just use a window A/C and cut and trim the opening. That is what is commonly used here. There are some considerations like not blocking the side vents but easily done. The 8000 I'm using cost around $200. I"m guessing your through the wall costs more and the sleeve costs extra.
