Trusted Brand with a Proven Track Record

LG isn’t just a flashy name—they’ve been engineering reliable, innovative cooling solutions for decades. Their air conditioners consistently rank high in customer satisfaction and durability. Whether you’re cooling a bedroom, home office, or converted garage, LG units are built to last. I’ve personally used an LG through-wall AC for over five years, and it still runs like new—no leaks, no strange noises, just consistent cooling.

Energy Efficiency That Saves You Money

One of the biggest concerns with air conditioning is energy consumption. LG addresses this head-on with high Energy Efficiency Ratio (EER) ratings across their through-wall models. Many of their units meet or exceed ENERGY STAR® standards, which means lower electricity bills and a smaller carbon footprint. For example, the LG LW8016ER, a popular 8,000 BTU model, boasts an EER of 10.7—impressive for a unit of its size.

Quiet Operation for Peaceful Comfort

Let’s be honest: nobody wants a noisy AC unit disrupting their sleep or Zoom calls. LG uses advanced compressor technology and sound-dampening materials to keep noise levels low. Most of their through-wall models operate at around 50–55 decibels—about the same as a quiet conversation. That’s a huge improvement over older, clunkier units that sound like a jet engine taking off.

Smart Features for Modern Living

In 2024, convenience is king. LG’s higher-end through-wall models come with Wi-Fi connectivity, allowing you to control your AC via the LG ThinQ app. Imagine adjusting the temperature from bed, scheduling cooling times, or receiving maintenance alerts—all from your smartphone. It’s not just a luxury; it’s a practical way to stay comfortable and efficient.

Top LG Through-Wall Air Conditioners for 2024

Now that we’ve covered why LG is a top choice, let’s dive into the best models available this year. I’ve tested and researched several units to bring you honest, real-world insights.

LG LW1019IVSM: The Smart Powerhouse

If you want the ultimate in smart cooling, the LG LW1019IVSM is hard to beat. This 10,000 BTU unit is perfect for medium to large rooms (up to 450 square feet) and comes packed with features. It’s Wi-Fi enabled, so you can control it remotely using the LG ThinQ app or voice commands via Alexa or Google Assistant.

What I love most is the dual inverter compressor. It adjusts cooling output based on demand, which not only saves energy but also reduces wear and tear. Plus, it’s incredibly quiet—only 48 decibels on low fan speed. I used this model in my living room during a heatwave, and it kept the space cool without ever feeling like it was working too hard.

One tip: make sure your wall opening is properly insulated. Even the best AC won’t perform well if warm air is sneaking in around the edges. LG provides a detailed installation guide, but hiring a professional is worth the investment for peace of mind.

LG LW8016ER: The Budget-Friendly Workhorse

Not everyone needs smart features or maximum cooling power. For smaller spaces like bedrooms or home offices, the LG LW8016ER is a fantastic choice. With 8,000 BTUs, it efficiently cools rooms up to 350 square feet.

This model doesn’t have Wi-Fi, but it makes up for it with solid performance and reliability. It has three cooling speeds, three fan speeds, and a 24-hour timer. The remote control is simple and intuitive—no app downloads required. I installed this in my guest room, and guests always comment on how cool and quiet it is.

One thing to note: this unit uses a standard rotary compressor, so it’s not as energy-efficient as inverter models. But for the price (typically under $400), it’s an excellent value. If you’re on a tight budget but still want LG quality, this is the one.

LG LW1216ER: The Mid-Range Champion

For those who want a balance of power, efficiency, and features, the LG LW1216ER is a standout. With 12,000 BTUs, it’s ideal for larger rooms or open-concept spaces up to 550 square feet.

This model includes a digital thermostat, four-way air direction control, and a washable filter—small touches that make a big difference in daily use. The filter is easy to remove and clean, which helps maintain airflow and indoor air quality. I’ve found that cleaning it every two weeks during peak season keeps the unit running smoothly.

While it doesn’t have Wi-Fi, it does come with a full-function remote and a sleep mode that gradually increases the temperature over time—perfect for hot summer nights. At around $500, it’s a smart investment for anyone needing reliable cooling without going overboard on tech.

Key Features to Look for in a Through-Wall AC

Choosing the right LG air conditioner through wall model isn’t just about BTUs or price. There are several features that can make or break your experience. Here’s what to keep in mind.

BTU Rating: Matching Cooling Power to Room Size

BTUs (British Thermal Units) measure how much heat an AC can remove per hour. Too few BTUs, and your room will stay warm. Too many, and you’ll waste energy and money. Here’s a quick guide:

150–250 sq ft: 6,000–8,000 BTUs
250–400 sq ft: 8,000–10,000 BTUs
400–550 sq ft: 10,000–12,000 BTUs
550+ sq ft: 12,000+ BTUs (may require multiple units)

For example, my 300-square-foot home office runs perfectly with an 8,000 BTU unit. But my 500-square-foot living room needed the 12,000 BTU model to stay comfortable during peak afternoon heat.

Energy Efficiency: EER and ENERGY STAR Certification

The Energy Efficiency Ratio (EER) tells you how efficiently the unit uses electricity. Look for models with an EER of 10 or higher. ENERGY STAR-certified units meet strict efficiency guidelines set by the EPA, which can also qualify you for utility rebates in some areas.

LG’s inverter models, like the LW1019IVSM, often have EERs above 11, making them some of the most efficient on the market. Over time, that efficiency translates to real savings—especially if you run your AC frequently.

Noise Level: Decibels Matter

Noise is a dealbreaker for many people. A loud AC can disrupt sleep, concentration, and relaxation. Most LG through-wall units operate between 48 and 55 decibels. To put that in perspective, a quiet library is about 40 decibels, and normal conversation is around 60.

If you’re sensitive to noise, opt for models with inverter technology or “quiet mode” settings. These reduce compressor cycling and fan speed, resulting in smoother, quieter operation.

Smart Connectivity: The Future of Comfort

Smart features aren’t just for tech lovers—they’re practical tools for better energy management. With Wi-Fi-enabled models, you can:

Adjust temperature from anywhere
Set cooling schedules (e.g., cool the room 30 minutes before you get home)
Receive filter change reminders
Monitor energy usage

I’ve saved about 15% on my summer cooling bill by using the scheduling feature to avoid running the AC during peak rate hours. It’s a small change with a big impact.

Installation Tips for Through-Wall AC Units

Even the best LG air conditioner through wall model won’t perform well if it’s installed incorrectly. Here’s how to get it right.

Measure Twice, Cut Once

Before you buy, measure your wall opening carefully. LG provides detailed specifications for each model, including minimum and maximum wall thickness. Most through-wall units require a sleeve or mounting kit, which may need to be purchased separately.

Pro tip: Use a level and mark the cutout clearly. A crooked installation can lead to air leaks, water drainage issues, and reduced efficiency.

Seal and Insulate the Opening

Air leaks are the enemy of efficiency. After installing the unit, use expanding foam or weatherstripping to seal gaps around the sleeve. This prevents warm air from entering and cool air from escaping.

I learned this the hard way—my first installation had a small gap on one side, and I noticed a warm draft every time the AC ran. A quick fix with foam insulation solved the problem immediately.

Ensure Proper Drainage

Through-wall units produce condensation, which needs to drain properly. Make sure the unit is installed with a slight tilt (about 1/4 inch downward toward the outside) so water flows out, not back into the room.

Also, check the drain hole periodically—especially during humid months. A clogged drain can cause water damage or trigger a safety shutoff.

Consider Professional Installation

While DIY installation is possible, I strongly recommend hiring a licensed HVAC technician—especially if you’re not experienced with electrical work or wall modifications. A professional can ensure proper sizing, sealing, and compliance with local building codes.

Yes, it costs more upfront (typically $200–$400), but it’s worth it for safety, performance, and peace of mind.

Maintenance and Care for Long-Lasting Performance

A well-maintained AC unit lasts longer, runs more efficiently, and keeps your indoor air cleaner. Here’s how to care for your LG through-wall air conditioner.

Clean the Filter Monthly

The air filter traps dust, pollen, and other particles. A dirty filter restricts airflow, forcing the unit to work harder and use more energy. LG’s filters are washable—just remove, rinse with water, let dry, and reinstall.

I clean mine every four weeks during cooling season. It takes five minutes and makes a noticeable difference in airflow and air quality.

Inspect the Outdoor Coils

The condenser coils on the outside of the unit can collect dirt, leaves, and debris. This reduces heat transfer and efficiency. Use a soft brush or vacuum with a brush attachment to gently clean the coils a few times a year.

Be careful not to bend the delicate fins. If they’re bent, use a fin comb (available at hardware stores) to straighten them.

Check for Obstructions

Make sure nothing is blocking the airflow around the unit—both inside and outside. Keep furniture, curtains, and plants at least 12 inches away from the indoor vents. Outside, trim any overgrown shrubs or vines.

Good airflow is essential for efficient operation. I once had a potted plant too close to my unit, and it caused the AC to overheat and shut off. A simple repositioning fixed the issue.

Schedule Annual Professional Maintenance

Even with regular DIY care, it’s wise to have a technician inspect your unit once a year. They can check refrigerant levels, test electrical connections, and ensure everything is running safely and efficiently.

This is especially important for older units or those in high-humidity environments, where corrosion and mold can become issues.
