You did it. You’re a DIY god. Your cat will now nap in a perfect, rectangular beam of cold air. Your utility bill will drop because this thing is efficient.
Will there be dust everywhere? Yes. Will you find drywall crumbs in your socks for a week? Also yes. But you’ll be comfortable, and that is the ultimate flex.
So go ahead, brag about it. Tell your friends, “Oh, the AC? I just installed it myself. No big deal.” It is a big deal. You earned that chill. Now, go grab an iced coffee and enjoy your personal arctic paradise.
