Which LG air conditioners are best?

Without a means to cool down, hot summer days can be miserable. Portable air conditioners are powerful and easy to set up in different parts of your home or office. One of the top manufacturers of portable air conditioners is South Korean electronics giant, LG.

Deciding which LG air conditioner is right for you requires assessing your overall needs and the size of space to be cooled down. For a quiet yet powerful performance, the top-recommended unit is the LG Smart Dual Inverter 10,000 BTU Air Conditioner.

What to know before you buy an LG air conditioner

Size of your space

The size of your room or cooling space determines the power required from your LG air conditioner. These power units are measured as British thermal units (BTUs) and are related to the square footage that can be adequately cooled. For a space of 200 square feet, you’ll want 8,000 BTUs. For every additional 100 square feet, add another 2,000 BTUs in power. As a result, a 300 square-foot room would require 10,000 BTUs, a 400 square-foot area would need 12,000 BTUs, and so forth.

Will you need to move the air conditioner around?

LG portable conditioners are convenient in that they can be moved to different locations in a particular space or moved to an entirely different part of a home or office as needed. However, LG also makes window air conditioners that can be semi-permanently placed in the window space. These are ideal for rooms where air conditioning will always be desired. You may want to consider a window unit in those circumstances.

Do you want to be able to heat the space in the winter?

Some models of LG air conditioners also feature a separate heating function for colder months. Check the LG product information to determine what each model offers. For more information on the options available, visit the Best Reviews summary on the best LG air conditioners.

What to look for in a quality LG air conditioner

Operating mode

In addition to cooling and occasionally heating, some LG air conditioners also include a fan-only mode, as well as a drying mode that helps remove moisture from the room without affecting the overall cooling.


If the power goes out unexpectedly while your LG air conditioner is running, the auto-restart function will retain the original settings once power is restored.

Noise reduction

On average, LG air conditioners run at 55 decibels. Some higher-end models run as low as 44 decibels, which is the sound of your local library.


Some LG air conditioners include a programmable timer that can turn the unit on and off based on the time of day and day of the week. This can help control costs and keep your electric bill in check as you use early morning and nighttime to help run the unit less.

Smart ThinQ app

Some higher-end models use the Smart ThinQ app, which allows users to operate their air conditioner while they are away via their smartphone. The app also is compatible with electronic personal assistants.

How much you can expect to spend on an LG air conditioner

The primary driver for LG air conditioner prices is the power, although some added features will increase the price too. For 8,000 to 10,000 BTU units, the price is $320-$400. The price of 12,000 to 14,000 BTU air conditioners is $460-$700.

LG air conditioner FAQ

What size of LG air conditioner do I need for vaulted ceilings?

A. If your room has ceilings higher than 8 feet, you will need to consider a more powerful BTU rating for your LG air conditioner. BTUs are calculated based on an 8-foot high ceiling, so look to increase your power output by 2,000 to 4,000 BTUs based on the overall height of your ceilings.

Can I plug my LG air conditioner into an extension cord?

A. Plug your LG air conditioner into a grounded wall outlet. This prevents any fire hazard due to overheating.
