You can’t just bolt that AC drywall. Drywall is basically giant cardboard. It will crumble, then laugh at you. You must find a stud—a vertical wooden beam that holds your house together. Use a stud finder, or the old method: knock on the wall and guess. (Spoiler: I’ve knocked a hole doing this. Don’t be me.)
Surprising fact: The first air conditioner, invented in 1902, was for a printing plant, not human comfort. It was so big it needed its own room. Your wall-mounted unit is a triumph of miniaturization—and you’re about to defeat it with a level and a prayer.

The Hole: Cutting Into Your Home’s Reality
You’ll need to cut a hole for the refrigerant lines and drainage. This is the moment of no return. Measure three times, then have a panic attack, then measure again.

Here’s the kicker: That hole must slope slightly downward. If it’s flat? Condensation will pool, and you’ll have an indoor swamp. I’ve seen it. It’s less “tropical paradise” and more “moldy shoe hotel.”
