Hi, I’m Samantha! When I started searching for a 15,000 BTU through‑the‑wall AC unit, I quickly realized I wasn’t alone. These units are one of the most popular options for cooling (and sometimes heating) large living spaces between 700 and 850 square feet.
Three brands kept coming up in reviews and recommendations:
-
GE – the dependable, budget‑friendly choice
-
LG – the feature‑packed smart option
-
Friedrich – the premium, ultra‑quiet performer
But which one is right for you? I compared efficiency, cooling power, heating options, features, installation, and cost — and here’s the full breakdown so you can make the right choice.
📊 1. Efficiency Ratings & Energy Costs
When you’re running a 15,000 BTU AC, efficiency isn’t optional — it’s the difference between a $75 electric bill and a $120 one.
GE
-
CEER values typically between 9.5–10.0
-
Many models meet Energy Star certification
-
Designed to hit DOE’s 2025 SEER2 standards
LG
-
Competitive CEER ratings ~9.8–10.5
-
Often marketed as high‑efficiency with Eco Mode
-
Energy Star models often save $70+ per year vs. older units
Friedrich
-
Among the highest CEER ratings (10.0–11.0)
-
Designed for premium efficiency with inverter technology in some models
-
SEER2‑compliant and often exceed minimum federal standards
💡 Samantha’s note: My Friedrich unit cost a little more upfront, but I save about $90/year compared to my old AC.

🧊 2. Cooling Performance
Performance is about more than BTUs — airflow design and noise level matter too.

-
Strong, reliable airflow for large rooms
-
Slightly louder than Friedrich models
-
Best suited for budget‑minded homeowners
LG
-
Known for powerful fans that cool rooms quickly
-
Multi‑directional louvers distribute air evenly

🔥 3. Heating Options
Not all 15,000 BTU units heat as well as they cool — but some do.
GE
-
Offers models with electric resistance heat
-
Reliable for mild winters but less efficient long‑term
LG
-
Limited TTW models with heating
-
When available, usually electric resistance rather than heat pump
Friedrich
-
Several heat pump TTW units for efficient year‑round comfort
-
Effective in moderate climates; supplemental heat may be needed in extreme cold
💡 Samantha’s tip: If you live where winters are mild, a Friedrich heat pump could cover you year‑round.
