I would like to install a window type A/C unit in a wood framed wall with a
brick veneer.
The unit will only need to cool one 14'x14' room, so I am hoping small
unit/opening will suffice.
The opening will be on the first floor of a two story structure, so there is
a lot of brick above with no other openings.
The brick and structure are in good condition.

How big (wide?) can the opening be before I have to install a lentil? Could
a wood header/stud/sill frame inside the new opening suffice?

Thanks for any ideas or suggestions.

Installing beans won't help much, but a lintel will. I'd make one from a
cross piece of angle iron with a leg on each side. Easily done if you have
any friends that weld. That would keep the opening minimally larger that
what is needed for the AC case. I'm sure some other ideas can work also.

Jeez, I didn't even think of a metal frame, only a lentil......hmmm...

Thanks for your suggestions.

Any unbridged opening wider than half the brick length can result in partial
collapse of the brickwork. Except in arches and such, brick is supported
only on the bottom. The support required would be a function of the weight
above and I think would be pretty substantial in your case. I would not
attempt this without professional advice.

You do not need support if you remove _one_ brick, and I imagine your
AC is bigger than that. Larger than that and you'll have to use a
piece of steel to support the brick. Do not use wood.

Have you thought about getting a unit that only requires a 4" hole?
The "portable" air conditioners have come down a lot in price, you can
store them out of the way in the winter and you won't have to mess with
framing and brickwork.
