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.

2 Years 3 Months and its dead..

Submitted by Bill Did It - 8/27/2020

I purchased this 12000 BTU unit to replace a 10000 in the living room in May of 2018. It is now August 2020 and it has stopped working properly. It still runs but the compressor will not kick in. I have tried all that LG said to do to reset it but to no avail. I really had faith in LG since the little 6000 BTU in one bedroom has been in use since 2013 and still works like a charm. My recommendation is if you are going to purchase this or any unit also purchase an extended warranty with it.... they dont make them like they use to sorry LnG Lifes not Good.

I bought this air conditioner to work along with a CoolBot to run a walk-in cooler. The refrigeration unit had stopped working and this setup was a lot cheaper than replacing the refrigeration unit. I dont use the walk-in cooler all the time but the last two weeks it has worked perfectly.

Submitted by Wally Gator - 9/20/2019

Living in the rural country and using several window air conditioners I learned the hard way to trust the ones that provide you with the longest and best service. Hence thats why I buy LG products. And I dont just mean air conditioners Ive learned to put my trust into something that provides me with service.

LW1216ER excellent choice

Submitted by dbtex - 9/8/2019

I have not used a window A/C unit in about 35 years so I was pleasantly surprised that this unit was so quiet and rattle free. The installation was fairly easy even though my double hung windows are aluminum and the instructions were not for this type window. I bought this unit to cool my double car garage which is about 22 x 22. Where I live in South Texas the summer temperatures are running from about 97 to 103 degrees every day and night time temps are staying in the 80s. I set the A/Cs thermostat at 84 and it has maintained that temp constantly. I have a digital thermometer mounted about 5 ft. high and about 20 ft. away from the unit so it confirms the whole areas temperatures very well. The remote control does not work well across the garage because there are storage racks and a car in the way. Also the remote control does not tell you what mode the unit is in. That information is displayed on the unit itself not on the remote. I would recommend this unit especially for its price and performance.

I bought this unit a month ago and im not real happy. The Clean Filter light came on after only a weeks use and stays on even after cleaning. It also goes from cool to energy save all by itself randomly. And its not very cool. My old 8000 unit that i replaced put out colder air.

This summer we had to replace the window a/c units in our bedroom and our living room. Since the existing units were LG and we had been pleased with them we bought two new LG window units. Now were surviving a summer heat wave and having to turn UP the temperature because were so so cool What a great problem to have when the outside feels like temperature is 110 degrees Both units are quiet effective and the filters are very easy to clean. Thanks LG.

It is weird to love an appliance?

Submitted by Average John - 7/18/2019

This is my second LW1216ER both bought to replace 5 year old Frigidaire 12000 BTU units. The difference is so significant its like theyre not even competing products. The old unit was incredibly loud. It used to wake me up when it kicked on. I dont even notice the LG cycling on and off. Further the LG unit cools dramatically better in energy saver mode than the Frigidaire did in normal mode. Ive a feeling the LG will quickly pay for itself. Finally LG has done a really smart thing by separating the frame from the internals. You install the frame in your window when its very light. THEN you slide the internals in and attach the front. SO much easier. Bravo LG

very quiet room a/c

Submitted by rafter - 6/13/2019

Easy install and very quiet running. This unit replaced an older Whirlpool unit with the same BTU rating but the old unit moved more cold air so I wish I would have ordered the next size up. Ive had this running 24/7 for three weeks now and no problems whatsoever. Easy filter to clean. I do wish the louvers could be positioned so the air pushed down a little more as my unit is mounted high on the wall and the area I want the air to flow is well below the direction it points. If this is a concern for you look at the photos of the unit and you will see that the air is directed straight out or up somewhat and not down at all.

The A/C cools the room very quickly. My only concern is the so called energy saver setting which cycles on and off every few minutes. This seems to me to be a contradiction in energy saving. Each time the unit comes on there is an initial electrical surge and then it goes to normal operation.

Submitted by BRW85 - 5/26/2019

This air-conditioner works like a charm is quick to cool down our living room and not the worst looking. The only thing I can complain about only reason I didnt give it 5 starts is it does make quite a bit of noise which Ive read can be fixed by propping it up with a piece of wood.

I cant believe what a great product this is I purchased this product about a month ago and the maintenance people installed it and it has been exceptionally great. It is quieter than I anticipated that is probably because of the professional installation and it keeps the temperature in the room very comfortable at all times. I havent seen the electric bill with this product yet but I am hoping it will not be too disappointing.

About 1 years ago we purchased a named brand 15000 BTU for use in our living room dining room but it was quite noisy and it just didnt satisfy. So we opted to purchase the 12000 BTU LG unit. The new unit is extremely quite. and easy to manage. Installation was very easy. It comes with it owns brackets to support the unit. If this continues we will be a good customer for LG products in the future.

I slide the old unit out and slide the new unit into the old case. It took aprox. 10 min. I feel sure the new unit will perform with no problems.
