10,000 Btu is an impressive output for a air conditioner that is as portable as this one. Has enough cooling power to handle a room up to 250 square feet, which means it can cool all but the largest of bedrooms as well as many living room areas. Three operating modes include a Dry mode, which allows the unit to operate as a dehumidifier, removing up to 2.6 pints of moisture an hour. Great for climates where the humidity climbs as high as the temperature in the summer months.
This model runs louder than some models we considered.
Because of the multiple fan settings on this model, its 8,000 Btu can cool a space up to 200 square feet. Unit is not terribly loud. Remote can be used to set the AC on a timer to turn off after a certain amount of time as well as when reaching the desired temperature. Dehumidifier removes 1.8 pints of moisture per hour.
Because it's designed for rooms of less than 200 square feet, this unit may not work well in most living rooms or other large rooms.
For users who need to cool a relatively small space, the 8,000 Btu on this model will get the job done. Because it's quieter than some more powerful units, it's an especially good option for an office setting. The humidifier on this unit can remove up to 1.8 pints of moisture from the air, a respectable amount for a model designed for smaller rooms.
Some users report that their drainage collector can fill up quickly, causing the unit to turn off until the collector is drained of water.
12,000 Btu is the most powerful unit LG produces, and that power allows this model to cool rooms up to 300 square feet, which means this AC will handle even large living rooms. The caster wheels make the unit easily portable, and the graphite gray color is a nice alternative to the traditional white color of most portable AC units. The dehumidifier will remove up to 2.6 pints of moisture per hour.
The lack of an energy-saving setting may cause this unit to be more expensive to run than some units.
While any powerful AC will cause a larger power bill, users report that this unit is more energy efficient than other 12,000 Btu models we considered, while accomplishing the same task of cooling rooms up to 300 square feet. The dehumidifier removes 1.2 pints of moisture, which is less than LG's other large unit, making this a good option for less humid climates.
While the unit can be moved between rooms using the casters, draining this heavy model may require two people to lift the unit.
There are a number of strategies you can employ to battle the heat. Some may only offer a temporary reprieve while others deliver a decisive victory. One of the best ways to stay cool in summer is to purchase a portable air conditioner, and LG makes some of the best.
An LG portable air conditioner is simple to set up: it can be quickly installed in virtually any room that has a window. And it can go with you if you need to move to a different part of the house. Additionally, an LG portable air conditioner can help eliminate allergens, increase your productivity in your home office, and even reduce the risk of dehydration.
If you'd like to learn about the different features available on the wide variety of models that LG offers, keep reading. If you'd just like some quick recommendations on which models might best suit your needs, consider the portable air conditioners that we've spotlighted on this page.
The most important factor to consider when purchasing an LG portable air conditioner is how powerful your unit needs to be, measured in British thermal units (Btu). (For more information on British thermal units, see the FAQ section below.)
The number of British thermal units you need is directly related to the size of the room you want to cool, measured in square feet. Too few, and it will be impossible to properly cool the room; too many, and the air conditioner's work cycle will be too short to adequately dehumidify the room. The air conditioner will work harder, wasting energy and perhaps shortening the life of the compressor.
The following are LG's recommendations based on room size:
LG portable air conditioners have a variety of features to consider when choosing the right model for your needs.
One convenient feature you’ll find on all LG portable air conditioners is the ability to switch between different operating modes: Cool, Fan, Dry, and Heat.
Cool: You can select any temperature between 60°F and 86°F and the unit functions as an air conditioner.
Fan: If you prefer to save some money on your electric bill, you can operate the unit in Fan mode. This shuts off the cooling element and engages a fan (high or low) to circulate air.
Dry: In this mode, the unit functions as a dehumidifier, removing moisture from the air without drastically affecting the overall temperature of the room.
Heat: Some of the high-end models also have a mode that turns the air conditioner into a portable heater that has the same temperature range as the Cool mode (60°F to 86°F).
Most LG portable air conditioners run at less than 55 decibels, which is about the volume of a standard refrigerator. Some of the high-end models feature low-noise performance and run closer to 44 decibels, which is only slightly louder than the ambient noise in a library.
Auto-restart: All of LG's portable air conditioners feature auto-restart. If there’s a power outage, this allows your air conditioner to reboot, automatically recalling the unit's previous settings.
Remote control: The less expensive LG portable air conditioners can be controlled remotely by using a small, handheld device that operates like a television remote. With more expensive models, you can control all aspects of the air conditioner via your smartphone with the LG SmartThinQ app. The app also allows you to remotely monitor the air temperature in the room where the air conditioner is located.
Timer: All LG portable air conditioners have a 24-hour programmable timer you can use to program the unit to turn on and off at specific times.
Although the variety of features plays a part in the cost of an LG portable air conditioner, the main driver of price is the unit’s power.
8,000 Btu: These models cost $320 to $330.
10,000 Btu: These models cost $370 to $400.
12,000 Btu: These models cost $460 to $500.
14,000 Btu: These models cost $600 to $700.
As pointed out above, it’s important to buy an LG portable air conditioner that has the right power for your room. But square footage isn’t the only variable that impacts the efficiency of an air conditioner. The following are a few other factors that affect an air conditioner’s performance.
Q. What is a British thermal unit?
A. You’ll find numbers for British thermal units on heaters and air conditioners. Without getting too technical, 1 British thermal unit (Btu) is roughly the amount of heat produced by burning a wooden kitchen match. With a heater, the number tells you the amount of heat that can be produced in an hour: the higher the number, the more powerful the heater. In an air conditioner, the number tells you how much heat can be removed from a room in an hour: the higher the number, the more powerful the air conditioner.
Q. Where should I position my air conditioner?
A. The unit should be placed on a level floor, close to a window, in a location that provides 20 inches of air space on all sides to allow for adequate circulation.
Q. Why do I need to place my LG portable air conditioner close to a window?
A. The air that comes out of the exhaust hose is very hot. If you don’t vent that hot air out of the room through a window, it will be impossible for the air conditioner to lower the temperature of the room.
Q. My unit is too far from an outlet. Can I use an extension cord?
A. No. An LG portable air conditioner should always be plugged directly into a wall outlet. Even if you do purchase an extension cord that won't overheat, it isn’t a permanent solution to the problem. The best solution is to hire an electrician to reposition the outlet so it’s in a more convenient location.
