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. 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.

False advertising. WiFi turns off with unit.

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

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

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

I recently purchased this ac to replace an older outdated ac. Once installed the machine itself works awesome blows cold and is quiet. However I do think the app should be updated.

Great unit All I expected

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.

After having our whole house air conditioner go out purchased one of these for our second floor which was close to 100 degrees in the afternoons and evenings. I had to modify the window with support mounts and then put it in the window. Turned it on and our bedroom was cool within seconds as this machine was going to town. Within 20 minutes our entire second floor was cool. The machine is FANTASTIC.

Window A/C

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.

Nothing Like a Brand New Air Conditioner

Dagwood 7/12/2018

This is my second LG 12000 BTU Window Air Conditioner the first one lasted about 8 years. The LG brand is ubiquitous in my area and I didnt 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 units 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 havent had an opportunity to use from a great distance. Bottom line I couldnt imagine having any other brand of window AC. Owning an LG 12000 BTU Window Air Conditioner effectively demonstrates the true meaning of their brand Lifes Good

AC works OK it isnt all that smart.

SteveZ 7/4/2018

Its smart features are rudimentary at best. Scheduling is start and stop only. No option to stop only or start only on schedule. To be sure it is off when you leave. No IFTTT support cant really automate it with other smart products such as motion detection door sensors to save energy. Plus the stupid thing beeps when any command is sent to it not only from the remote but during scheduled on/off If you dont need smart features it works fine as AC unit.

Installation and Performance Review

Quiet Please 6/28/2018

Instructions for homeowner installation of the air conditioner were not very clear. I defaulted to an engineers perspective when looking at the collection of pieces and that worked out The room to be air-conditioned rated a minimum of 9500 BTU so the capacity of a 12000 BTU air conditioner seemed capable of the cooling task. The LW1217ERSM works but I expected it to be stronger. My greatest demand of an air conditioner is quiet performance. This unit was evaluated by independent agencies as one of the quietest air conditioners on the market whispers just above the level of a fan. Sorry but the LW1217ERSM is not quiet enough for my toleration. Most disturbing is the noise-level jump when the compressor automatically turns on when the fan is blowing. As noted my greatest demand is quiet performance.

Quietest for Price Range

mirage790 6/18/2018

Bought this unit about a month ago and am very pleased with it. Our old unit was so noisy we couldnt hear the TV in the next room so when we needed a new one I researched and this was unit had the lowest decibel rating for its size within my price range. Of course it is not as quiet as a whole house air conditioning unit but I did not expect it to be. The instructions are not the best but it took my husband and I a little less than an hour to install. The cabinet is installed in the window opening first and then the unit itself is slipped in and secured. That is a whole lot easier than out old one which you had to hold all that weight while trying to secure it and not accidentally drop it out the window. One note: Just be sure you have the correct slant so the water can drain properly outside. The unit itself is easy to learn how to use. The only thing I wish is that the fan speed was automatic but it stays at the speed you set it. Also it would be better if the remote had the thermostat in it instead of being in the unit itself. What I like best is the energy saving feature which actually turns the unit off when the temperature is reached. Then the fan comes on at set intervals to test the air temp and when needed the compressor turns on to cool the air again. Or it can be just on and the fan continues to run whether the compressor is running or not. I highly recommend this unit as it cools very well.
