LG LW8017ERSM Air Conditioner Review


The Energy Efficiency Ratio (EER) of this window air conditioner is 12.1. The GE AEM05LX is the only window air conditioner we tested that has a higher ratio of 12.4. While the LG LW8017ERSM is more expensive to run than the other AC units we looked at, this isn’t due to inefficiency. Rather, it’s because it’s more powerful than the other models we looked at and can chill a wider area.

The LG LW8017ERSM extracts more moisture from the air than any other device we looked at, with a rate of 2.2 pints per hour. If you live in a humid area, this makes it an especially good choice. It also features a dehumidify-only mode that you may use to remove moisture from the air without cooling it.

This is a midrange window air conditioner in general, but it is one of the more expensive models we looked at. It also costs more to operate, with an annual energy cost of $60 projected.


There are several modes on the LG LW8017ERSM, including an energy-saving mode. When the compressor is turned off, the energy conservation mode switches off the fans. To keep the room cold, the fans and compressor will cycle on and off concurrently as needed.

It also has a sleep mode that gradually raises the thermostat temperature during the night to save energy and prevent you from waking up in a cold environment. In addition, this mode prevents the compressor from overworking.


This machine serves as an air conditioner as well as a fan. The speed may be adjusted (there are three settings plus auto mode) and it runs softly at 52-58 dB. The LG ThinQ app can control the air conditioner remotely, and it’s also compatible with Amazon Alexa and Google Assistant. If you need to cool a large area, check sure your window air conditioner can do the task. This type is suitable for smaller rooms (up to 340 square feet), but the LG LW1816ER is a better choice for larger settings.


The LW8017ERSM weighs 57 pounds and is made of plastic and metal. The device’s front is made of plastic, with vents, buttons, and a small screen in the upper right corner. Nothing protrudes, thus there should be no issues with little pieces grabbing on items or breaking. This gadget is straightforward to mount firmly in the window, set up, and use, but it isn’t ideal if you plan on moving the AC around a lot. If that’s the case, a portable air conditioner would be a better option.


The current going rate for this air conditioner is $319.99, which is significantly higher than similar models (but those versions don’t feature ThinQ technology!). When it comes to returns, you’ll be on your own, but delivering the device to your home is free. The LW8017ERSM comes with one-year parts and labor guarantee, which is convenient. However, based on 6,279 reviews and a score of 4.3 out of 5, it appears unlikely (though not impossible) that you will need the warranty.

Design & warranty

This product utilizes up to 8,000 British thermal units (Btu), which is the amount of energy required to heat or cool one pound of water by one degree Fahrenheit. As a result, the LG LW8017ERSM can cool up to 340 square feet of space. The following most powerful unit has a maximum area of 260 square feet. It’s also one of the louder window air conditioners we tested when set to the highest level. However, considering its strength, this is to be expected.

For one year, this unit’s warranty covers all parts, including the compressor. This is an industry-standard warranty that provides important coverage as you break in your new air conditioner. It is, however, significantly less extensive than the greatest warranties, which cover the compressor for a period of five years. If you have any queries about warranty coverage or anything else, you may contact LG by email, phone, or live chat.

The LG LW8017ERSM includes nearly all of the features we looked for in window air conditioners. It has one of the finest EERs we’ve seen, which is impressive given that it can move 220 cubic feet of air per minute. With that much power, it can quickly chill a large space of up to 340 square feet.
