When your old window AC finally stops working, you’ll probably want the best LG air conditioner to replace it. There are many different air conditioners on the market today, but if you’re looking for an affordable window unit, consider the LG LW8017ERSM! These window air conditioners cool up to 340 sq. feet, can be controlled via Wi-Fi, & cost about $320.

Why We Like It – LG LW8017ERSM

The LG LW8017ERSM air conditioner is an 8,000 BTU unit available for an affordable price. It can be controlled over Wi-Fi via LG ThinQ, and also works with both Google Assistant & Amazon Alexa.

  • Can Be Controlled Via LG ThinQ
  • 52 dB Window Air Conditioner
  • Includes A Remote Control
  • Has A Smaller Cooling Area Compared To Other Window AC Units


This unit doubles as both an air conditioner & a fan. Speed is adjustable (with three different settings plus auto mode) and operates fairly quietly around 52-58 dB. The air conditioner can be controlled remotely via the LG ThinQ app, but it’s also compatible with Amazon Alexa & Google Assistant. If you need to cool a large space you will need to make sure your window AC can handle a large cooling area. This model is suitable for smaller rooms (up to 340 sq. feet), but for larger spaces, the LG LW1816ER is a better option.

Energy Efficiency

You won’t have to spend a lot on electricity to run this wall unit. LG appears to have focused on energy efficiency for this model, so despite including smart ThinQ technology and being WiFi-enabled (like the LG LW1017ERSM, the device still does very well by Energy Star standards. The Energy Guide awards this AC unit an EER (Energy Efficiency Ratio) rating of 12.0 and estimated the yearly cost of running this air conditioner will be around $65. This is excellent because the annual operating costs of similar models run from $65 up to $127.


Like most modern LG air conditioners, the LW8017ERSM has an easy-clean air filter. This means that the air filter can be removed from the front of the unit, cleaned, dried, and put back into the AC – no need to replace the filter! Another benefit is that you won’t have to take the unit out of the window to reach the filter. Even though the unit is much lighter than other models (at 57 lbs.), we appreciate the easy access to the filter.


The LW8017ERSM is 57 lbs. of plastic and metal. The front of the device is plastic with vents, buttons, and a small screen in the upper right-hand corner of the device. Nothing sticks out, so you shouldn’t have any problem with small parts catching on things or breaking. Mounting securely in the window, setting up and using this device is simple enough, but it’s not ideal if you plan on moving the AC around a lot. If that’s the case, you might want to go with a portable AC unit instead.


$319.99 is the current going rate for this AC unit, which is slightly on the high-side of similar models (but those models don’t have ThinQ technology!). You will be on your own when it comes to returns, but shipping the unit to your house is free. LG gives you a one-year warranty on parts and labor for the LW8017ERSM, which is useful. However, based on the score of 4.3 out of 5-stars based on 6,279 reviews, it seems unlikely (though possible) that you will actually need the warranty.

LG LW8017ERSM Wrap Up

The LG LW8017ERSM is an affordable window unit that’s perfect for cooling smaller spaces. While 340 sq. feet isn’t as much space as other more expensive models, it is decent for the price range. You also get remote control capabilities over WiFi, which is a feature that’s lacking from many similarly-priced units.
