Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

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.

LW1216ER excellent choice

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.

Plash 8/29/2019

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.

Cool and Quiet

PeggyD 8/2/2019

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.

Testing the unit after unboxing it the fan did not work but the motor was hot. In 2 weeks could not get LG to have a service person contact us. Had a neighbor A/C guy look at it and get it working. Amazon did give a refund though.

Air conditioning become extremely noisy

Mark_NY 7/18/2019

I bought LG 12000 btu/hr air conditioning on May of 2017 at BJs. Two seasons it works very good but this year at beginning of summer its start to make extremely loud noise looks like that bearing on the fan is broken. Im so disappointed that LG AC is broken after 2 years of service.

It is weird to love an appliance?

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

It seems ok I like the dry feature but it does not seem really cold but I have only used it a short time the lowest temp it goes to is 60 which seems odd to me but this is the heaviest a/c I have ever had if it didnt weigh so much I would have returned it not sure how I am going to deal with this thing I barely got it in the window and its big thank god it actually fit of course not in the window I intended it for but whatever wish I had noticed the thing weighs 90 pounds or whatever

very quiet room a/c

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.

Jekyll Dan 6/9/2019

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.

Great Air-conditioner

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.

Lila J 5/17/2019

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.

We have this unit installed through the wall on our sun porch. The bottom of the unit is about 8 above the floor and it effectively cools and dehumidifies this 15 x 20 insulated space with 11 - 4 x 4 sliding windows with thermopane and low E glass. It does a great job and is easy on the electric meter.

Works Better than Expected

aheiss 9/4/2018

We purchased this air conditioner at the beginning of a very hot and humid Philadelphia summer. We are more than impressed with its ability to cool our 600sq. foot downstairs of our row home quickly and efficiently. This is my first experience with a window unit and I cant believe how great its going so far. Set up was relatively easy but I needed my fiancee to help lift it into place. It was too heavy for me myself. I definitely make this purchase again

Danny179 9/1/2018

I noted the very high rating this window air conditioner got in Consumers Reports magazine. I bought it through J.C. Penny. I cant say much good for the shipping: the package was pretty well beat up and the plastic grill cracked although just cosmetic. The unit cools very well with a high EER which saves money. When on energy saving it comes on every three minutes to check air temperature when compressor has shut off. That seems excessive: other units I looked at come on every 10 minutes. But the unit overall is outstanding and Id gladly buy it again. It makes me consider other LG products something I hadnt thought of doing before. Danny

CONSTANTLY TURNS OFF AND ON

pdeg 8/31/2018

I bought this unit two months ago and when on ENERGY SAVER Mode it turns off and on constantly. I emailed the MFG and was told that is normal for the fan cycle to turn and on approx. every three minutes to test the room air to determine if active cooling needs to be resumed. This unit turns off and on more often than every three minutes. It turns on and off anywhere from thirty seconds to one minute or later when it wants to it will come back on then shuts off anywhere from ten seconds to thirty seconds afterwards then starts up again and runs for approx. thirty seconds than shuts down until it repeats this routine. This acts this way mostly in the evening hours when its a bit cooler outdoors Yes there are times that it will stay on for longer periods of time. I have owned other brands and none of them have required them to start and shut off all the time to check room temperature plus the air blow is not as good as the other brands are. I will continue to use this item for the rest of the season simply because stores are now stocking up with winter items and air conditioners are not a winter item. But next year I will be replacing it with another brand. And its for this reason that I do not recommend this item.

So Far So Good...

James AC Unit 8/11/2018

I have owned this A/C for about 5 weeks now and it has helped me to survive one of the longest and hottest periods that I can ever recall here in the NE area where I live. Thanks LG. I have a lot to learn about A/C units. This is my first A/C unit ever purchased. I am happy with the performance of this device to date. The installation was tough in some ways. Id like to suggest that you find a way to allow the angled metal bracket installed on top of the device to be placed in an adjustable way so that it is easier to install the device in the back-leaning position that is recommended in the documentation.
