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 effective airflow. If you want 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 your needs.

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.

How We Decided

Air conditioners are an essential item for anyone who lives in a part 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 towards 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.
  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.
  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.
  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.

LG Air Conditioners FAQs

Is LG a good brand of air conditioner?

Yes, LG is a respected electronics brand that makes a variety of products for consumer and commercial use. Within the consumer segment, the brand is known for creating countless home appliances that are durable, including air conditioners.

How do I choose an air conditioner?

Consider the type of air conditioner you want to pick. Do you want one that needs to be mounted or a portable air conditioner? Begin by confirming the square footage of the space you want to cool. Regardless of which type of air conditioner you select, buying a unit that’s too small or too big will result in inefficiencies. Using the square footage, find a BTU rating that is compatible with the room size. Next, consider the installation method. Some units like portable air conditioners will be easy to install while window units are a two-person job, and mini-splits may require professional installation.

Is it bad to have an oversized AC unit?

In short, yes. While a unit that’s rated for more capacity than your room can quickly cool or heat your room, you’ll most likely find that it consumes more energy and may result in higher energy costs. It can also push out air that’s too hot or too cold, making it uncomfortable to be around. Additionally, because it’s drawing so much power, it may create an excessive load on your electric circuitry, leading to shorts, and power outages. This is why it’s best to properly match your BTUs to the space you’re cooling or heating.

Is it cheaper to leave an air conditioner on all day?

Yes, but with caveats. While it’s cheaper, in the long run, to keep your AC on all day especially in hot weather, you can’t leave it at the same temperature. For energy efficiency and to reduce the burden on your appliance, you should opt for an auto setting that works to achieve a certain temperature and then adjusts the fan speed or temperature to a lower setting to reduce power consumption.
