DUAL Inverter Compressor™

LG air conditioners with Dual Inverter Compressor™ eliminate unnecessary noise and provide cool temperatures with up to 25% more energy efficient than the minimum ENERGY STAR® certification requirement*. Experience the powerful yet quiet performance of LG’s ultra-efficient, revolutionary inverter technology.


Maximum Cooling for Maximum Comfort

LG DUAL Inverter Window air conditioners provide exceptional cooling power that will keep you and your family cool, comfortable and in control.


The Coolest Energy Savings Around

Unlike typical air conditioners that turn on and off to adjust temperatures, the DUAL Inverter Compressor™ constantly adjusts its speed to maintain desired temperature levels. That means less fluctuation and up to 25% more energy efficient than the minimum ENERGY STAR® certification requirement*.

*Inverter Technology is a key attribute of LG’ new room air conditioners. It is used in conjunction with a variable-speed compressor and adjusts compressor motor speed to regulate temperature. This is more energy efficient than non-Inverter Technology room air conditioners, which turns the compressor either on or off to regulate temperature. In Department of Energy approved testing, LG’s Inverter room air conditioner model (LW1517IVSM) showed 25% Combined Energy Efficiency Ratio (CEER) positive difference when compared with ENERGY STAR® minimum CEER requirement.


Quiet Operation

LG air conditioners operate at low sound levels of just 44dB, thanks to LG's unique BLDC Motor and DUAL Inverter Compressor™, which eliminate unnecessary noise and allow for smooth operation that you’ll barely notice.

Total Control From Your Phone

Total Control From Your Phone

Access your air conditioner anytime, anywhere on any wi-fi enabled device, thanks to LG's exclusive SmartThinQ® app. Turn your air conditioner on or off or change the temperature right from your smartphone. It even works with Amazon Alexa and the Google Assistant, so you can control your air conditioner with the sound of your voice.

What People Are Saying

Rated 5 out of 5 by from I've heard great things about the efficiency!!! I've been hearing great things about the efficiency in off grid groups and solar forums. Also how quiet it is! I hope the technology is scalable to 5,000-12,000 btu units! Looking forward to a 9,000 btu unit for my next tiny house! Maybe next year? Right now just posting since I got a 'deal' on one end of season. I've not setup mine yet. I like LG since they seem to care about efficiency, My large TV sips electric, important if you live off grid on solar electric!

Rated 5 out of 5 by from Amazong and powerful Lg air conditioner I honestly think the world of this air conditioner by lg. My first impression of it was about wireless features and connecting to wifi. I must admit im highly impressed of its great features but even more with the performance. Ot was very simple anf easy to install but the capacity of cooling my whole 3 bedrooms house was mind blowing. I would definitely recommend this product and buy in the feature.Very happy customer.

Rated 5 out of 5 by from Great window AC Unit! The LG Window air conditioner was fairly easy to install. I'm not a handy person, but following the simple instructions in the manual had my unit up and running in no time. I was extremely pleased with unit. It is able to cool most of my home outside of the bedrooms. It's set up in my living room and seems to cool more efficiently than my old central air. The unit runs quietly compared to other wall units I have had. The controls are simple. It's easy to switch between modes and the LG SmartThinQ app is a nice option to have. I would recommend this AC unit to anybody looking to find a great unit that does a great job cooling a decent sized space with minimal noise.

Rated 4 out of 5 by from Great air conditioner This LG 14,000 BTU Dual Inverter Smart wi-fi Enabled Window Air Conditioner is awesome! I love that I can control it with Alexa right from my phone. I don't have to be in the room to control the air conditioner. It is a great product. My only issue is that due to the weight of the air conditioner it is very difficult to install. It takes a bit of work to secure it so that it doesn't fall.

Rated 5 out of 5 by from Wow Air Conditioning At Its Best! I absolutely love my Lg wifi enabled air conditioner. I was so anxious for my husband to get home to install it. Installation was so easy, if I didn't need help lifting it I could have installed it myself. We had it running in less than fifteen minutes. It runs very quietly, and its very efficient at cooling the room. The SmartThinQ app was very user friendly. It also works with alexa it has the most up to date technology available. If your in the market for an air conditioner I highly recommend you purchase the LG. you want be disapponited

Rated 5 out of 5 by from Low Noise and Wi-Fi sooooooo quiet!! quiet, cools 800 sq feet well, high temperatures here sometimes 90 F, humidity can be hight, AC cools and lowers humidity well. Well designed for window insertion for double hung window. Follow instructions closely to install. Took me about two hours. The unit is secure in the window and sealed well with parts provided. I would buy it again. I have been using it for the last warm days of Detroit's warmest days of humidity. This is perfect since I am off the Detroit riverfront. This is ideal for lofts or any large open space. Quietest air conditioner I have ever had. Pleasant to look at and easy to install. Highly recommend this product!!

Rated 1 out of 5 by from Happy that I purchased it At first I was skeptical because I didn’t know much about the LG products but I needed a large air conditioner and that was the only one available so I took a chance and bought it. when I got home I put it in the window. that was in June of this year and I have not shut it since. the thermostatic control is wonderful because it automatically goes up and down depending on how much cooling I need in the house. It keeps the house at a constant comfortable temperature. I am very satisfied and would recommend LG products to anyone

Asked by: Cyrus23
Hi Cyrus23. Please pardon us if we are misunderstanding your inquiry. We are not clear on if you are inquiring if LG has any plans for making an Inverter Smart wi-fi Enabled Window Air Conditioner that features cooling and heating or if you are asking if we will be making any air cinditu=ioners that feature both heating and cooling. We currently have Window Air Conditioners that feature both heating and cooling in our current lineup. Regrettably, we currently do not have any information on if LG plans to come out with any Heating/Cooling Inverter Smart wi-fi Enabled Window Air Conditioner...^IFV

Joel You state it has a EER of 11.2 The standard units have a 12 EER. Does this mean the standard unit will use less electricity than the double inverter unit?

Asked by: drice
Drice, both EER and CEER assume the air conditioner is always running at full capacity. The majority of the time the full BTU capacity of the unit is not required because not every day is 100+ degrees. Under such conditions, regular ACs will cycle on and off to maintain a room temperature. By contrast, this unit will reduce the compressor load to operate like a lower-BTU model, once the desired temperature has been met. This method is more efficient than cycling on and off the compressor. If window ACs had SEER ratings, this unit would likely have a higher SEER rating than the 12 EER units, as SEER takes into account the fact that full cooling capacity isn't always required. You'll probably start to see SEER ratings on window ACs once more units begin taking advantage of variable compressor technology.
