📘 Introduction

Choosing a through‑the‑wall AC unit isn’t as simple as picking the first one that fits. When I went shopping for a 12,000 BTU system, I quickly realized that brand matters just as much as BTUs.

The three leaders in the 10,000–12,000 BTU range are:

LG — sleek, tech‑forward, and quiet.
GE — dependable, affordable, and easy to maintain.
Friedrich — premium, durable, and whisper‑quiet.

By the end of this guide, you’ll know which one best matches your home, budget, and comfort goals.

👉 According to Energy Star, properly sizing and selecting an efficient AC can cut cooling costs by 20–30%.
