What People Are Saying

Rated 5 out of 5 by from We should have done this sooner! We bought this 3 weeks ago and couldn't be more pleased with our purchase! Easy to install and the design makes it a cinch to clean and maintain the air filter. We particularly enjoy the energy saver feature. It's so nice to enjoy the summer sun, knowing we have a cool home to retreat into! Although our unit is rated for a smaller area, it keeps our whole home cool and comfortable! 5 out of 5 stars!

Rated 4 out of 5 by from WORKS GREAT, BUT WHY FILTER CLEANING SO FAST So this is working great, 10 days, the filter cleaning light came on. I followed the 3 step process of cleaning filter(s). It won't turn off. I vacuum and power sprayed the outside fins and I still can't get light to turn off. I drained the water and the front filter is so clean, it can't be that. I don't know

Rated 5 out of 5 by from Nothing Like a Brand New Air Conditioner This is my second LG 12,000 BTU Window Air Conditioner, the first one lasted about 8 years. The LG brand is ubiquitous in my area and I didn't hesitate to buy again. I took my time with the installation, which is simple, but you may need a second pair of hands to pick up the box and unit. The LG Window AC unit runs at a comfortable decibel and all of its modes and functions work wonderfully. The AC unit's features provide nice cool air from 3 fan speed settings of your choice, thermostatic temperature control, plus a "dry" function for humid days. We had extreme record heat the first week in July and monsoonal weather the following week. Our LG Window AC was able to handle the demand of cooling our home especially with the use of the "dry" function, which kept the air comfortably dry on humid days. The Wi-Fi feature is a plus, but I haven't had an opportunity to use from a great distance. Bottom line, I couldn't imagine having any other brand of window AC. Owning an LG 12,000 BTU Window Air Conditioner effectively demonstrates the true meaning of their brand, "Life's Good"

Rated 3 out of 5 by from Okay I just recently bought this AC unit. The only downfall is that it doesn’t blow out the air fast enough. It’s a quiet AC unit which is good.

Rated 3 out of 5 by from Great AirConditions execpt for the WiFi I bought this air condition a couple of weeks ago and I really like it. There are however, two features I really wish it had: 1) remembers the setting the last time it was turned on. 2) the WiFi app would let me control the air condition remotely. Because of these two missing features I can only give it two stars.

Rated 1 out of 5 by from Even after in Home Svc, no cooling I bought this unit from Home Depot June 24th of 2018. After install our bedroom had an almost unchanged room temperature, this unit was slightly larger than necessary for room size. Contacted LG, they sent out a tech who replaced the whole electronic module. Checked for cold air, looked great! That night, the compressor never came on after initial power up. We sweated, even under a sheet. Fed up, I returned unit to Home Depot for full refund!

Rated 5 out of 5 by from Performed as promised My unit is about a month old now. I replaced an older 14,000 BTU with this 12,000 BTU in a well insulated 900 square foot room. It cools the room well. It is also much quieter than my old unit.

Can the LG LW1217ERSM a/c be used as a built-in through the wall unit?

Asked by: GramPam
The LG 12,000 BTU Smart wi-fi Enabled Window Air Conditioner, Model # LW1217ERSM requires a standard single-hung or double-hung window for proper installation. The outside of its cabinet must extend outward for at least 12" and there should be no obstacles, such as a fence or wall, within 20 inches from the back of the cabinet because that will prevent heat radiation from the condenser. All its side louvers must remain exposed to the outside of the structure. Restriction to outside air will greatly reduce the air conditioner's cooling efficienct=y and that could also lead to the unit burning itself out. It cannot be installed using a wall sleeve, a hole in the wall, and non-window installations are not recommended...^IFV

Can I disable the wi-fi on window A/C units.

Asked by: Bob1949
The ENERGY STAR® LG 12,000 BTU Smart wi-fi Enabled Window Air Conditioner, Model # LW1217ERSM uses Wi-Fi that allows the user to control the unit with the corresponding LG Mobile app. To use the Wi-Fi and app, the AC must be registered on the SmartThinQ® website. The minimal specifications are for an Android OS 4.0 or higher at 340 x 480 or higher screen resolution or an iOS or higher at 960 x 640 or higher screen resolution. Phones below this minimum specification cannot operate the unit and some phones meeting the above criteria may not operate every function of the unit. The supported routers are Cisco, Apple, ASUS, D-Link, TP Link, Trendnet, Actiontec, Netgear and 2Wire. Other routers may not support the Wi-Fi application. The above models are optimized for Wi-Fi service, but any cell phone that does not meet the minimum system requirements will not be able to run the program...^IFV

I would like to use this AC with my generator. What is the starting current of the unit?

Asked by: BrianInFlorida
The ENERGY STAR® LG 12,000 BTU Smart wi-fi Enabled Window Air Conditioner, Model # LW1217ERSM has a running wattage of 990W and its surge wattage that will last for a second or two when the compressor kicks on is about 1.5 to 2 times that. Regrettably, we do not have access to the information on the nameplate which is required to be attached to the unit's motor by the National Electric Manufacturers Association is the governing body which sets the standards for the manufacture of electrical equipment in the USA that has to show the Full-Load Current. Please contact our Support Center at (800) 243-0000 to inquire if they have access to this information...^IFV

How donI reset the “Clean Filter” light after cleaning the filter?

Asked by: bigSQUISHY76
After cleaning the filter, press the temperature up and down buttons together to turn off the clean filter light. The filter reset must be done from the unit's control panel not the remote control. ^CP
