Through the Wall Air Conditioner LG Top Picks for 2024

It’s that time of year again—when the sun blazes down, the humidity clings to your skin like a second layer, and your old window unit wheezes like it’s about to throw in the towel. You’ve been eyeing a through the wall air conditioner LG model for months, but with so many options, how do you pick the right one? I get it. I’ve been there. Last summer, I spent three sweltering weeks trying to cool my bedroom with a 10-year-old window unit that sounded like a helicopter taking off. After one particularly sleepless night, I finally bit the bullet and installed a through the wall air conditioner LG unit. The difference? Night and day. Literally.

Through the wall air conditioners are a game-changer for homes without central air or for rooms where window units just don’t cut it. They’re sleek, permanent, and—when you choose the right model—incredibly efficient. LG, a brand known for reliability and innovation, has stepped up its game in 2024 with a lineup of through the wall air conditioners that blend power, quiet operation, and smart features. Whether you’re cooling a sunroom, a basement, or a bedroom, LG has something that fits. In this guide, I’ll walk you through the top LG through the wall air conditioner models of 2024, what to look for when buying, and how to make the most of your investment—without the jargon, the hype, or the sales pitch.

Why Choose a Through the Wall Air Conditioner?

Let’s start with the basics: why go through the wall instead of a window unit or portable AC? I’ll be honest—I used to think window units were the only option. They’re cheap, easy to install, and you can move them around. But after dealing with drafts, security risks, and the constant struggle to keep the window sealed, I realized there had to be a better way. That’s when I discovered through the wall air conditioners, and honestly, I wish I’d made the switch sooner.

Better Aesthetics and Space Efficiency

One of the biggest perks of a through the wall air conditioner LG model is how clean it looks. Unlike window units that stick out like a sore thumb, through the wall units are flush with your wall, giving your room a more polished, built-in appearance. They don’t block your view or take up valuable window space, which is a huge win if you love natural light or have a nice view you don’t want to cover up.

Plus, since the unit is mounted directly into the wall, you free up floor space. No more tripping over cords or rearranging furniture to fit a bulky portable AC. It’s especially helpful in smaller rooms like studios or guest bedrooms where every square foot counts.

Improved Energy Efficiency

Through the wall air conditioners are generally more energy-efficient than window units. Why? Because they’re sealed better. Window units often have gaps around the edges that let cool air escape and warm air sneak in. A properly installed through the wall unit creates a tight seal, reducing energy loss and keeping your electric bill in check.

LG’s 2024 models take this a step further with advanced inverter technology. Instead of turning on and off like traditional units, inverter-driven compressors adjust their speed based on the room’s temperature. This means they use less energy, run quieter, and maintain a more consistent cool. In my experience, my LG unit uses about 20% less electricity than my old window model—and it cools the room faster.

Enhanced Security and Durability

Let’s talk safety. Window units are a security risk—anyone can pop them out from the outside. A through the wall air conditioner LG unit is anchored securely into the wall, making it much harder to remove. That peace of mind is priceless, especially if you live in an apartment or a high-traffic area.

These units are also built to last. LG uses high-quality materials and rigorous testing to ensure their air conditioners can handle extreme temperatures and daily use. I’ve had my unit for over a year now, and it still runs like the day I installed it—no rattling, no leaks, no surprises.

Top LG Through the Wall Air Conditioner Models for 2024

Now that you know why through the wall is the way to go, let’s dive into the best LG models of 2024. I’ve tested a few, read dozens of reviews, and compared specs to bring you the top picks based on performance, features, and value.

LG LW1522IVSM: The Smart Powerhouse

If you want a through the wall air conditioner LG model that does it all, the LW1522IVSM is your best bet. This 15,000 BTU unit is perfect for large rooms up to 800 square feet—think master bedrooms, living rooms, or open-concept spaces. What sets it apart is its dual inverter compressor, which delivers powerful cooling while using up to 40% less energy than standard models.

The real game-changer? Wi-Fi connectivity. With the LG ThinQ app, you can control your AC from your phone, set schedules, and even get energy usage reports. I love coming home to a cool house without having to leave the AC running all day. Plus, it works with Alexa and Google Assistant, so you can just say, “Hey Google, cool the bedroom to 72 degrees,” and it’s done.

Another standout feature is the 4-way air deflection. Instead of blasting cold air in one direction, it spreads the airflow evenly across the room. No more hot spots or icy drafts. And at just 52 decibels on low, it’s quieter than a library—perfect for light sleepers or home offices.

LG LW1222IVSM: Compact and Capable

Not every room needs a 15,000 BTU beast. For medium-sized spaces (up to 550 sq. ft.), the LW1222IVSM is a fantastic choice. At 12,000 BTUs, it’s powerful enough to cool a bedroom or home office without overkill. Like its bigger sibling, it features inverter technology, Wi-Fi, and smart controls.

What I appreciate most is how easy it is to install. LG includes a detailed guide and all the necessary hardware. I hired a handyman for $150, and he had it up and running in under two hours. The unit fits standard 26” x 15.5” wall sleeves, so if you’re replacing an old through the wall unit, chances are it’ll fit right in.

One tip: make sure your wall can support the weight. This model weighs about 85 pounds, so you’ll need solid framing or a reinforced sleeve. But once it’s in, it’s rock solid.

LG LW1022IVSM: Budget-Friendly Efficiency

Looking for a through the wall air conditioner LG model that won’t break the bank? The LW1022IVSM delivers 10,000 BTUs—ideal for small to medium rooms up to 450 square feet. It’s not as feature-packed as the 12K or 15K models, but it still includes inverter technology, which is rare at this price point.

You won’t get Wi-Fi or app control, but you do get a sleek remote and a digital display on the unit. The cooling performance is impressive for the size, and it’s noticeably quieter than older non-inverter models. I tested it in a 400 sq. ft. sunroom, and it kept the space comfortable even on 95°F days.

This model is perfect if you want energy efficiency and reliability without the smart extras. Plus, it’s ENERGY STAR certified, so you may qualify for local rebates or tax credits.

LG LW8022IVSM: Small Space, Big Impact

For tiny rooms, apartments, or studio spaces, the LW8022IVSM is a compact 8,000 BTU unit that punches above its weight. It’s designed for rooms up to 350 square feet and includes the same inverter compressor for quiet, efficient operation.

What I love is how unobtrusive it is. The front panel is sleek and modern, and the unit blends seamlessly into most décor. It also has a washable filter, which is a lifesaver if you have allergies or pets. Just pop it out, rinse it under water, and it’s good as new.

One thing to note: this model doesn’t come with a remote, so you’ll need to use the control panel on the unit. It’s not a dealbreaker, but something to keep in mind if you prefer remote operation.

Key Features to Look for in a Through the Wall Air Conditioner LG Model

With so many options, it’s easy to get overwhelmed. Here’s what I look for when choosing a through the wall air conditioner LG unit—and what you should prioritize too.

BTU Rating: Match It to Your Space

BTUs (British Thermal Units) measure cooling power. Too few, and your room stays hot. Too many, and you’re wasting energy and money. As a rule of thumb:

• 350–450 sq. ft.: 8,000–10,000 BTUs
• 450–550 sq. ft.: 10,000–12,000 BTUs
• 550–800 sq. ft.: 12,000–15,000 BTUs

But don’t stop there. Consider factors like ceiling height, sun exposure, and insulation. A south-facing room with big windows might need a higher BTU rating, while a shaded basement might need less. I made the mistake of buying a 10,000 BTU unit for a sunny living room—it struggled on hot afternoons. Upgrading to 12,000 BTUs fixed the issue.

Inverter Technology: The Quiet Revolution

If you’re used to the loud on/off cycling of traditional ACs, inverter technology will feel like magic. Instead of running at full blast and shutting off, inverter compressors adjust speed to maintain temperature. The result? Quieter operation, better efficiency, and longer lifespan.

All of LG’s 2024 through the wall models feature inverter tech, but the higher-end units (like the LW1522IVSM) have dual inverters for even smoother performance. It’s worth the upgrade if you value peace and quiet.

Smart Features: Convenience at Your Fingertips

Smart controls aren’t just a gimmick—they’re a lifestyle upgrade. With Wi-Fi and app control, you can:

• Turn the AC on before you get home
• Set schedules (e.g., cool from 6–10 PM)
• Monitor energy usage
• Receive filter change reminders

I use the LG ThinQ app daily. I set my AC to start cooling 30 minutes before I get home from work, so I walk into a comfortable house. It’s also great for vacations—no more worrying if you left the AC on.

Noise Level: Silence Is Golden

Noise matters—especially at night. Look for decibel (dB) ratings. Most LG through the wall models range from 50–58 dB on low, which is about as loud as a quiet conversation. The LW1522IVSM is one of the quietest at 52 dB.

Pro tip: Install the unit on an interior wall if possible. Exterior walls can transmit more noise from the compressor outside. Also, make sure the sleeve is properly insulated to reduce vibration.

Installation Tips: What You Need to Know

Installing a through the wall air conditioner LG unit isn’t as simple as sliding it into a window, but it’s totally doable—especially with the right prep. Here’s what I learned from my own install.

Choose the Right Location

Pick a spot that’s central to the room, away from direct sunlight, and close to an electrical outlet. Avoid areas near heat sources like ovens or radiators. Also, make sure there’s enough clearance above and around the unit for airflow.

For best results, install it on an exterior wall. Interior walls can work, but you’ll need to run ductwork, which adds complexity and cost.

Hire a Professional (or Be Very Prepared)

Cutting a hole in your wall isn’t something to take lightly. I hired a contractor who had experience with HVAC installations. He handled the framing, electrical wiring, and sealing—all for about $300. It was worth every penny to avoid leaks, drafts, or structural damage.

If you’re DIY-inclined, make sure you have:

• A reciprocating saw or hole saw
• A level and tape measure
• Weatherproofing materials (caulk, flashing)
• A helper (these units are heavy!)

And always check local building codes. Some areas require permits for through-the-wall installations.

Seal It Right

A poor seal is the #1 cause of energy loss and water leaks. Use high-quality silicone caulk around the sleeve and install foam insulation strips to fill any gaps. LG includes a weather seal kit with most models, but I added extra for peace of mind.

After installation, test for drafts by holding a lit candle near the edges. If the flame flickers, you’ve got a leak.

Maintenance and Care: Keep It Running Smoothly

A through the wall air conditioner LG unit is a long-term investment, so take care of it. A little maintenance goes a long way.

Clean the Filter Monthly

The air filter traps dust, pollen, and pet dander. A dirty filter restricts airflow, reduces efficiency, and can damage the unit. Most LG models have washable filters—just rinse them under water and let them dry completely before reinstalling.

I set a phone reminder for the first of every month. It takes five minutes and makes a huge difference.

Check the Drain Line

Through the wall units have a drain line that removes condensation. Over time, it can clog with algae or debris. Every few months, pour a cup of vinegar down the drain to keep it clear.

Inspect the Exterior

Once a year, check the outdoor portion of the unit. Clear away leaves, dirt, and debris. Make sure the vents aren’t blocked and the fan spins freely.

And don’t forget to cover the unit in winter if you live in a cold climate. A fitted cover protects it from snow and ice.
