Top Through-the-Wall Air Conditioner Brands Compared: LG vs. GE vs. Friedrich

Intro — Three Names Homeowners Can Trust

If you’ve been shopping for a through-the-wall AC, three brands keep showing up: LG, GE, and Friedrich. They’ve each earned loyal followings for reliability and design, but they aren’t identical.

After installing and servicing hundreds of units, I can tell you where each shines—and where they fall short. Here’s the straight talk.

---

1. LG — Quiet Efficiency for Everyday Comfort

If you want something sleek, quiet, and efficient, LG is tough to beat.

Highlights

• Whisper-quiet: Around 53 dB on low—quieter than normal conversation.

• Energy Star models: Most exceed CEER 10.5.

• Precise controls: Digital thermostats and 24-hour timers.

• Good humidity control: Dry Mode keeps air comfortable without overcooling.

Example Model

LG LT0816CER 8,000 BTU Energy Star
• For rooms up to 330 sq. ft. • CEER 10.7 • 53–59 dB noise range • Fits standard 26-inch sleeves

Pros

✅ Extremely quiet
✅ Energy-efficient
✅ Modern controls
✅ Easy installation

Cons

⚠️ Cooling-only models dominate
⚠️ Slightly higher price per BTU

Jake’s take: “LG units are like a Honda Civic—dependable, quiet, and low maintenance.”

---

2. GE — Durable Workhorse with Heating Options

For reliability and dual-season performance, GE is a long-time favorite.

Highlights

• Cooling + electric heat: Great for mild winters.

• Heavy-duty frames: Steel construction for longevity.

• Universal fit: Compatible with most 26-inch sleeves.

• Easy parts access: Nationwide availability.

Example Model

GE AJEQ12DWJ 12,000 BTU with Electric Heat
• Cools & heats up to 550 sq. ft. • CEER 10.6 • 208/230 V • Durable steel chassis

Pros

✅ Year-round comfort
✅ Tough construction
✅ Strong airflow
✅ Easy to service

Cons

⚠️ Slightly louder (56–61 dB)
⚠️ Some models need a 230 V circuit

Jake’s take: “GE units are built like tools — not toys. They run hard for years if you treat them right.”

---

3. Friedrich — Premium Performance and Longevity

When a customer asks for something to last 15 years or more, I point to Friedrich.

Highlights

• Commercial-grade build: Metal chassis and sealed motors.

• QuietMaster Tech: Sound-dampening reduces noise by 25%.

• Wi-Fi smart control: Select models work with Alexa and Google.

• Tight temperature control: Holds steady within 2 °F.

Example Model

Friedrich Uni-Fit UCT10A10A 10,000 BTU Energy Star
• CEER 10.7 • Smart Wi-Fi app • Fits 24.5-inch sleeve • Adapter kits for retrofits

Pros

✅ Ultra-quiet and durable
✅ Smart home integration
✅ Excellent air distribution
✅ Ideal for retrofits

Cons

⚠️ Highest price tag
⚠️ Slightly heavier installation

Jake’s take: “Friedrich is the Cadillac of wall units—built to run quietly for decades.”

5. Installation & Compatibility

Most LG, GE, and Friedrich models fit standard 26-inch sleeves.
Still, measure before you buy:

• LG: Best with LG or Friedrich Uni-Fit sleeves.

• GE: Works with Amana WS900 and GE RAB46A.

• Friedrich: Needs adapter kits for older GE/LG sleeves.

6. Noise & Comfort Levels

If you’re sensitive to sound:

• LG is quietest for bedrooms.

• Friedrich runs nearly silent in larger spaces.

• GE moves more air but adds a slight hum.

Friedrich’s QuietMaster insulation really does cut vibration. In side-by-side tests, it’s about 3–4 dB quieter than GE models.

---

7. Maintenance & Lifespan

Keep filters clean monthly and vacuum coils each season—these three brands reward basic care with decades of service.

---

8. Energy Efficiency & Costs

Here’s what you can expect to pay and save:

Even though Friedrich costs more up front, its low energy use and long lifespan often make it the best value over time.

Jake’s Tip: “Don’t just compare price tags—compare how much you’ll spend to run the thing for ten years.”

---

9. Heating Performance Matters Too

• GE: Most reliable for electric heat output; great for mild climates.

• Friedrich: Select models use heat pump tech for better efficiency.

• LG: Primarily cooling, with some models offering fan-only winter circulation.

If you want true four-season comfort without extra equipment, GE or Friedrich are your go-tos.

---

10. Customer Experience & Warranty

Friedrich earns points for robust customer support and long warranties on sealed systems. GE also stands out for easy parts ordering.

12. Jake’s Recommendations

If you’re still deciding:

• On a budget: Go with LG.

• Need heating too: Pick GE.

• Want top tier: Buy Friedrich.

All three brands are solid; it’s about matching your lifestyle and space.

Jake’s rule: “The best AC isn’t the most powerful—it’s the one that fits your home and runs quiet every day without you thinking about it.”

---

13. Bottom Line

• LG: Quiet, efficient, ideal for smaller rooms.

• GE: Rugged, versatile, handles heating too.

• Friedrich: Premium, whisper-quiet, built for the long haul.

Whichever you choose, install it with a proper wall sleeve (like the Amana WS900), seal it tight, and you’ll have steady, quiet comfort for years.
