Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you. Please consult a sales associate about delivery options.

Great AC - one missing feature

Submitted by ScubaKevin - 7/6/2019

Bought tow of these and really like them. Love having the remote access to adjust the temp/etc. The scheduling feature in the Smartphone app is basic and allows for on/off scheduling. Wha tis needed is the ability to vary/set the desired temperature as part of the schedule also.....that would make this the perfect AC unit in my opinion :-. Overall great value and features for the money. I would recommend purchasing.

Solid performing A/C

Submitted by Rodstech - 7/5/2019

This is the second Texas summer with the LG A/C and so far I am completely happy with the performance I mostly cool a 500 sq ft area master bedroom and bathroom and it can easily keep the area way colder than most people like when I have the door open to the rest of the house 1100 sq ft it can still keep the house comfortable the A/C is fairly quiet even when the compressor turns on off. I plan to purchase either a second one or spend the extra money on a LG Dual Inverter A/C. the only thing that I wish LG would improve is their SmartThinQ app it is sluggish on my iPhone 7 Plus other than that I would recommend this A/C

Good performance so far

Submitted by CaptainCamera - 7/1/2019

Good performance so far including four 94+ degree days last week. I like that the unit seems to use evaporating the water from humidity as a cooling method so there is not a lot of dripping and water coming out of the unit. The only fault I have in the unit is that the energy saver mode turns on the fan every three 3 minutes to check the temperature -- thats much too often and puts a lot of wear and tear on the fan relays. I would much prefer that it check the temperature every 15 or so minutes like some competitive air conditioners do. It would also be good if us users could alter the fan on/off time in the energy saver mode to make it worthwhile. I am resigned to leaving it on regular mode where it runs all the time. I checked with a company tech and they said users cannot change the programming of the fan-on timing for energy saver mode. I have not tried the WIFI enabling -- seems like it might be a good feature but the instructions look like it takes a lot of effort to set it up -- Ill keep it as a regular unit and not energize the WIFI.

Quiet and cools ...

Submitted by Ibdjoker - 6/23/2019

Purchased this through Home Depot online. Arrived in pretty good shape with the box slightly damaged. There was some slight damage to the unit see photos but I thought not enough to return to the store. We have approximately a 400sf living room thats vaulted. We purchased this size due to different online sources recommending an increase in size by a factor of 1 or 2. It definitely cools the room Would have given it another star if not for: I had trouble with the WiFi option. It wouldnt completely sync up and would drop out...the most I could get was 90 completion. Ill try again when the weather gets hotter and the unit is powered on continuously. It is a beast at 92lbs I purchased a window shelf to provide extra support. Do I recommend this unit...if I get the WiFi to work yes. If not save your money and get the unit without WiFi.

Quiet but powerful

Submitted by bsadler18 - 6/1/2019

This is the third window unit Ive purchased for this particular room and it is by far the best. Its very quiet no rattle. And the quiet hum is consistent no loud power-up when the system switches from fan ot colling. Very nice. And the cooling seems to radiate throughout the room. My last unit seemed cold only when standing right infront of the vents. This is the best window air conditioner Ive ever owned.

Very satisfied

Submitted by Tom 60660 - 5/26/2019

This LG model LW1217ERSM air conditioner replaced my Amana 12M12TA. The LG has 200 BTU more cooling power and uses 190 watts less than the Amana. On top of that the LG is quieter and cools my 574 square foot 1 bedroom apartment just fine. The wifi is awesome. The remote included with the air conditioner only works within line-of-sight of the air conditioner controls but the wifi and cell phone app allow me to control any feature including power on/off from anywhere I have cell phone service. You have to be patient with the cell phone app though. After opening the app give it a few seconds to update itself with the current status of the air conditioner. Dont try to give it any commands before then. It will also take a few seconds to confirm your air conditioner commands. If you do that it works fine. Like any air conditioner you have to put some thought into your specific installation needs. I had to buy some additional foam strips at Home Depot to seal around the air conditioner and the gap between the windows. I also had to buy longer support feet for the rear support. The LG uses regular nuts and bolts for support feet. The included bolts werent long enough to reach my outside window sill. Setting up the wifi requires a medium level of technical ability. The cell phone app will walk you thru it. If it doesnt work its because you did something wrong. I am very satisfied with my LG model LW1217ERSM and would not hesitate to recommend it. The only unknown is whether or not it will last 15 years like my Amana did.

False advertising. WiFi turns off with unit.

Submitted by DisappointedinHi - 11/28/2018

The WiFi turns off then you turn off the unit meaning you can no longer control it remotely. This means in order to use the remote control features you need to literally leave it on 100 of the time. Theres also no standby mode. Do yourself a favor and dont buy this.

Stopped Cooling within Two Weeks from purchase

Submitted by Still HOT - 10/9/2018

This unit was purchased for my elderly Mother-in-law. In an effort to be proactive we done a really nice weather tight instillation to save on energy. This unit stopped cooling within Two Weeks and also started making a strange noise. We followed the trouble shooting steps first and it still didnt work. We contacted LG and scheduled an appointment for a Technician to come out and repair it. Two weeks later her unit is still out and we havent seen or heard anything from the Technician that LG Customer Service scheduled for us. Its still HOT in Alabama Thanks Still HOT in Alabama

Doesnt cool waste of money for the features

Submitted by Mouss - 8/28/2018

My apartment is about 500 sq foot. So thinking I can get one to cool the whole 1 bedroom apartment with nice features with wifi and have a great reviews. Oh man this unit takes forever to cool down on a 80 degree day. Today it was 95 plus day with humidity and struggles to keep it cool below 80 degrees. I wish I can return this device is garage. Me thing I get another unit. To help put and it is doesnt. It feels great standing in front of the unit but high fan speed feels that it low. On a 80 degree day it takes about 4 hours cool to like 76 degrees. Ha energy saver mode its it annoying. That is if it works and reach to my desire temperature. If a miracle it does reach to 72 degree it would cool to 66 degrees and then shut off. Then does it cycle kicks in the the ac around 76 then take another 2 hours just try to cool back to 72. Before people question. Yes I do clean the filter out regular when the light turns on and if direct sunlight is the issue It is 10 pm now and it struggling to keep the apartment at 78 degrees. I want to love this device I cant and I want to return but I cant

Submitted by Happydays - 7/31/2018

The unit is very quiet for a window unit. Ive owned many and this is the most quiet unit Ive owned. Most important thing is to size out your unit correctly. If your room size is towards the upper limits I would get the next larger size. You can stick with the recommended size if there is low heat load like little outside sun light room is the lower floor of 2 story home space is well enclosed with little loss of air.

Window A/C

Submitted by Bigdaddy8723 - 7/21/2018

First of all mounting was a pain. Our windows dont slide up/down but sideways. In fact the all homes in our area are that way. It took some thought and time to mount the unit. The unit works fine except I cant tell the difference in the fan speeds. We use it to keep our garage cooler in 100 plus degrees. It gets the temperature down to a low of 84 degrees even when the A/C is set at 68 degrees. I thought it would get it a little cooler.
