Finding the best LG air conditioners can feel like an overwhelming process if you don’t know what criteria to use. You need to consider the square footage of the room you want to cool and find a unit with BTUs that are compatible with that space. Consider whether you want a mounted or portable unit, and look for an option with higher energy efficiency and a strong CFM rating for adequate airflow. If you’re going to link your air conditioner to a smart assistant, look for WiFi-enabled models. And also consider options such as a dehumidifier or supplemental heat if your space isn’t warm enough with the current heating system.

After researching through countless consumer reviews, we nominated the LG LW1816ER Air Conditioner as our Top Pick. Keep reading to learn more about the rest of our picks, and the criteria we used to create this guide and identify the best air conditioners for you.

Top 10 Best LG Air Conditioners

 #1  LG LW1816ER Air Conditioner


WHY WE LIKE IT: The best window air conditioner for larger rooms up to 1,000 square feet thanks to 18,000 BTUs of power with a dry mode for increased comfort.

  • Ideal for rooms up to 1,000 sq. ft.
  • 18,000 BTUs
  • 530 CFM, 11.8 EER
  • Doesn’t include a heater option

If you’re trying to cool a larger room, then you know how important it is to find an air conditioner with increased power. This LG LW1816ER is up to the challenge thanks to 18,000 BTUs of power.

  • Auto-evaporation mode for continuous use
  • 230 CFM rating
  • Requires manual drainage of collection basket

Small rooms deserve to be efficiently cooled. And that’s why we like the LP0818WNR air conditioner. This is another portable AC unit that is ideal for smaller rooms of up to 200 square feet. You’ll get 8,000 BTUs of power and a 230 CFM rating. We like that this LG air conditioner that’s portable only weighs 58.4 pounds, making it a truly mobile solution. This is important as even though portable air conditioners are designed to be moved, they can be incredibly heavy.

While this model has an auto-evaporation mode which is designed to be more efficient, we did note that you need to manually drain this unit. And that can be a nuisance as it requires tipping the unit to drain the collection basket. You also get two cooling and two fan speeds, and a dry mode. We did like that this model has a fairly impressive evaporation rate of up to 117.6 pints per day. And you may also find a better, portable, evaporative air cooler for the summer, from our review on the best outdoor air conditioners.

 #7  LG LW2217IVSM Air Conditioner

  • Dehumidifier with 158.4 pints/day evaporation rating
  • Only available as a certified refurbished model

Portable air conditioners can be a great solution for people who need to cool a room, but aren’t prepared or able to install something more permanent like a traditional window unit or even a mini-split system. The LG LP1414WSRSM is a WiFi-enabled portable air conditioner that can be linked to Alexa and Google Assistant or be operated through the SmartThinQ app. This pick is 14,000 BTUs and is rated for rooms up to 500 square feet.

While this model is only available as a certified refurbished unit, we think it has a lot to love. You’ll get a 278 CFM which is fairly strong for air circulation. This three-in-one solution includes cooling, dehumidifying, and fan functions. The dehumidifier has an evaporation rate of 158.4 pints per day, which is on the higher end. This model comes with two cooling and two fan speeds along with a sleep mode. But you may also be interested in a combo unit in the class of the best portable air conditioner and heater.

 #10  LG LP0817WSR Air Conditioner


WHY WE LIKE IT: An LG portable air conditioner that’s budget-friendly with three-in-one functionality for smaller rooms up to 200 square feet and an easy-to-use control panel.

  • Streamlined control panel with LCD temperature display
  • 8,000 BTUs for up to 200 sq. ft.
  • 3-in-1 cooling, dehumidifier, and fan function
  • Lower EER rating of 8.2
  • 2 fan speeds and 2 cooling speeds

For people with smaller rooms, it can be hard to find an air conditioner that’s not overpowering your room. Picking a unit that’s too powerful can lead to increased energy consumption, possible power outages, and a room that’s uncomfortable because it’s too cold. The LP0817WSR is an LG portable air conditioner that’s easy on your wallet, easy to install, and effective. With 8,000 BTUs it’s perfect for smaller rooms up to 200 square feet.

Note that this portable AC isn’t WiFi-enabled and has a slightly lower 8.2 EER as compared to other LG air conditioners. Additionally, because of the lower BTU rating, you’ll get a 220 CFM. Still, we like that it has a straightforward control panel that’s easy to use with an LCD temperature display. This unit is also a three-in-one solution with cooling, a dehumidifier, and a fan function. The dehumidifier can remove up to 91.2 pints per 24 hours. You’ll also get two cooling and two fan speeds. And if you live in drier climates where the humidity levels are relatively low, then you may need the best evaporative air conditioner.

How We Decided

Air conditioners are an essential item for anyone who lives in areas of the world where hot weather is a part of life. To create our guide, we looked at the following key features — the BTU rating, style, room size, CFM and EER ratings, programmability, and additional features. You’ll find that we focused on two main types of air conditioners, those that must be mounted (either wall or window mounts) and portable air conditioners.

The BTU rating and room size are two factors that go hand in hand. Picking the right BTU rating requires knowing the square footage of whatever space you want to cool. In our guide, the BTUs ranged from as low as 7,300 to as much as 22,000. And understandably, the compatible square footage ranged from as small as 200 square feet to as much as 1,300 square feet.

But to find an efficient model, you also need to pay attention to the cubic feet per meter (CFM) and energy efficiency rating (EER). The CFM dictates how effectively a unit can move air throughout the space while the EER determines how efficiently an air conditioner can operate and whether it can pose a risk of higher energy bills.

Next, we considered whether an air conditioner was programmable. While basic functions like a 24-hour timer, sleep, and eco mode are fairly standard, we also looked for models that are WiFi-enabled. This means that they can be linked with smart assistants such as Alexa or Google Assistant. And it increases the intuitive nature of the product, allowing you to control it remotely, even if you’re not home.

Finally, we considered additional features. Primarily, this came down to a dehumidifier setting and supplemental heat. A dehumidifier can help to reduce the temperature in a room by removing the humidity. And we focused on the evaporation rate which is usually listed in pints per hour or pints per 24 hours. And a supplemental heat function can be useful for people in spaces that lack heat, or where the built-in heater isn’t as effective.

Best LG Air Conditioners Buyer’s Guide

The Most Important Factors to Consider

  1. BTU Rating
    Start by thinking about the BTUs or “British Thermal Units”. The BTU rating confirms how much square footage an air conditioner can effectively heat or cool. If you have a larger room, you’ll need a unit with a higher BTU rating. BTUs can range from as low as 8,000 to as much as 36,000 BTUs. For example, 22,000 BTUs can handle cooling about 1,200 square feet like what the unit in our LG LW2217IVSM review is capable of cooling.
  2. Style
    There are a variety of air conditioner options to meet your needs. Aside from central air, which requires ductwork to be installed, you can also find portable models, mounted units, and even mini-split systems.
    • Mounted units must be installed in a window or through the wall, while portable air conditioners require a simple window hose installation.
    • Think about whether or not you’re able to install something permanent, or if you want the freedom to move your unit from room to room, like how you can do with the model in our LG LP0818WNR review.
    • And, make sure your installation allows you to clean the unit, especially if you’re learning how to clean AC vents.
  3. Room Size
    Your air conditioner’s BTU rating should be compatible with the square footage of the space that you want to cool. Don’t just get a unit with the largest BTU rating as you could end up paying for more power than you can use. For example, the unit in our Frigidaire air conditioner review with an 18,000 BTU rating is suitable for cooling 1,170 sq. ft. If your home has much less square footage than that, you most likely don’t need all that power.
  4. CFM and EER Ratings
    Also known as the CFM, the cubic feet per meter rating is going to be important for windows and portable units. CFM denotes an air conditioner’s efficiency at circulating air through a room. A higher CFM number usually means that the unit offers better airflow. But remember that CFM must be considered after you’ve selected a unit with the right BTU level for the space you’re heating or cooling. But if you’re concerned with energy efficiency, pay attention to the EER rating. This figure represents how efficient an appliance is. The higher the EER rating, the more efficient an appliance is.
  5. Programmability
    In addition to having a control panel or a remote, some people may be concerned about smart integration or truly remote operation from their smartphone. While this will usually come with a price increase, you can find models that are WiFi-compatible or are already smart assistant-enabled to work with popular options like Alexa, Google Assistant, or Apple Home.
  6. Additional Features
    If all you care about is basic cooling, then additional features may not matter. But nice add-ons like a dehumidifier can remove humidity from a room and naturally reduce the temperature without requiring you to crank the AC and use more energy.
    • Other options like self-evaporation can be nice for portable units, while a heating function is nice if you need to supplement your home’s built-in heating system.
    • Some units use two filters for air and condenser coil filtration to further improve your home’s air quality like the unit in our LG LP0817WSR review.
