This window unit is currently the best wifi air conditioner on the market (in addition to being one of the best LG air conditioner models! With a cooling power of 10,000 BTU, a fair price tag of $389.62 (you can get a used model for even less), and a variety of smart control options, this window AC could be the perfect replacement for your current unit! Read on to see how this unit will benefit you, and how it compares to other top-performing air conditioners.

Why We Like It – LG LW1017ERSM

In this LG LW1017ERSM review we’ll go over the advantages of this older, wi-fi controllable air conditioner From its rating of 10,000 BTU (capable of cooling rooms up to 450 sq ft) to its integrated LG ThinQ, what’s not to love? If you do not need Wi-Fi capability but the same cooling capacity, consider the less costly LG LT1037 HNR air conditioner.

  • Fairly Quiet At 52 dB
  • Works With Google Assistant & Amazon Alexa
  • Has Integrated Smart Features Via LG ThinQ
  • This AC Unit Is Heavy, Weighing 74 Pounds
  • Not Suitable For Larger Spaces


These window air conditioners are rated for 10,000 BTU, & are capable of adequately cooling rooms up to 450 sq ft in size (for 1,000 sq ft of cooling power, check out the LG LW1816ER). The air conditioners have 3 different cooling/fan speeds and feature 4-way air deflection so you can easily cool specific parts of your room. Unfortunately, they are a little louder than other models, producing up to 55 dB of noise inside, & 63 dB outside.

Energy Efficiency

The LG LW1017ERSM window air conditioner earned an Energy Star rating of 12.0. LG projects the yearly cost of operating the unit to be $81, which is a little bit below the
average rating. Annual operating costs for similar models range from $65 to $127, so while the LW1017ERSM isn’t the most efficient model around, it’s still pretty good. That said, it is important to remember that the $81 is an estimate, so your electric bill may be higher or lower depending on how much you use the device. If you’re strictly looking for a more energy-efficient unit, then you’re better off with the more advanced LG LW1517IVSM window air conditioner.


Like many other LG air conditioners, including the LG 115V dual inverter smart window A/C, this model has a removable/washable air filter. It’s easy to remove the filter because it just slides out of the side of the unit. Thankfully, this model includes a “Check Filter” light that alerts you when the air conditioner needs to be changed, so you won’t have to check it manually (although it’s still a good idea!). The light is located on the upper right-hand side of the device next to the display screen above the control buttons.


Like most window models, this AC is made of plastic and metal (if you’re looking for a portable mode, check out the LG LP1419IVSM!). Most customers seem to be happy with it (based on its current rating of 4.5 out of 5-stars based on 6,386 Amazon reviews), but a few have reported it failing upon arrival. If this happens, make sure to contact customer service right away, because the warranty (which covers both parts & labor) only lasts for one year.


For $389.62 you can pick up this AC unit (a cheaper alternative is the LG LP0818WNR). If you’d like to save some money, there are also used versions available starting at $302.86. Both options come with free delivery via Amazon; sadly, returns are not free. The unit comes with a one-year manufacturer’s warranty that covers parts & labor. However, if you’d like more protection you can also buy a 3-year protection plan for $33.99 or a 4-year plan for $44.99.

LG LW1017ERSM Wrap Up

The LG LW1017ERSM is a unit we would recommend! For less than $400 you get 10,000 BTU of cooling power with wifi control via ThinQ. While it would have been nice if the unit weighed less, a heavyweight is, unfortunately, a common occurrence among window units, so we can’t fault the LW1017ERSM too much. Still, if you’re looking for a quiet wifi-controllable unit for a large room or small apartment, you can’t go wrong with this unit!
