First, let’s talk about why you’d even bother. Window units are fine, but they block the view and invite bugs in like uninvited guests at a cookout. A through-the-wall AC is sleek, out of the way, and makes your home look like a pro did it. Plus, you get to keep your window for, you know, actual air.
The secret sauce? It’s all about planning. Mess this up, and you’ll have a drafty hole that whistles like a teapot in a windstorm. But get it right, and you’ll be chilling—pun intended.
