This is my fourth LG air conditioner. All the other three units are still working well after four years of use, which is the reason I purchased this unit; my expectations were high and the reviews were good. My complaints:
1. The fan for this unit is loud on setting two and three. This fan noise may be a problem for people who want to use this air conditioner in their bedroom. Many other people on Amazon have made a similar comment about loud fan noise.
2. Build quality -cheap. Moving the plastic louvers that direct the air up or down is very difficult. In another review Dave says he found it almost impossible to move these louvers up and down; I agree with Dave. The plastic part that opens and shuts the unit to allow for or close off outside air is so flimsy that I am afraid to use it. The plastic levers that direct left/right air flow are as cheaply made as the open and shut lever. The louvers that are attached to the sides of the unit to allow for snug fit in the window are as cheap as everything else in the unit and were difficult to fit properly to the open window, as others have also noted.
First update: As expected, this airconditioner works well to quickly cool my office space. When I put the LG on the room was 82 degrees. Within half an hour the temperature had dropped to a comfortable 76 degrees. The compressor for the airconditioner makes very little noise, but as mentioned, the fan is loud, especially on high speed.
Other reviewers have mentioned that they received their units damaged. I recommend that these people contact Amazon customer service. I have always had good luck getting a replacement for equipment damaged in transit. Also, some reviewers have talked about problems with installation of this machine. This A/C fits neatly in the window. Unfortunately, as mentioned, the louvers providing the seal keeping warm air out are cheap and difficult to adjust properly. Extra insulation material is needed to keep warm air out of the room.
Second update: I have added a star to this review. After six weeks of daily use this air conditioner works as advertised under difficult conditions. The build quality of my three other LG air conditioners is better than this machine being reviewed and they run more quietly. Now that the machine is installed in the window, I don't touch any of the louvers that adjust and direct the flow of air so it doesn't matter now that they are cheap or difficult to use. As noted, this air conditioner may be loud on high fan speed, but it does cool well, which is exactly what it is supposed to do. If it is anything like my three other LG air conditioners, it will work reliably for a long time.
Third update: I have not mentioned the remote control on this AC, which works well and does control many functions of the machine. On fan speed one the AC is quiet enough for a bedroom. Lastly, the energy saver does work well to reduce the amount of electricity the AC uses. I turn it on when I leave the office and it effectively maintains the set temperature of the room. This LG A/C is a good machine as many other reviewers agree.

I read a lot about several comparable A/C units at this price range and this seemed the best to me. Having bought it, I'm glad that I did. It is quiet and quickly cools down our room. I think the complaints about noise must be from a faulty unit or improper installation, because ours is barely noticeable half the time. I would highly recommend this unit to anyone who wants a quiet powerful air conditioner.

My landlord recently installed one of these in my apartment. The overall build quality seems typical of similar size units. There's a lot of plastic parts that can vibrate and rattle against each other. The seals (or lack thereof) between the inside and outside of the unit are very poor and could use a lot of extra foam. Installation is tricky with the power cord coming out the bottom and a non-flat bottom to the unit. The adjustable side panels seem to sit up and back from the window sill more than they should. This is, unfortunately, all par for the course.
My biggest complaint is that the fan motor is quite loud. Wind noise isn't too big a factor, especially at low speed, but there's a very noticeable low hum. By comparison however the compressor is nearly silent. It's hard to tell when the compressor is running and when it isn't. Airflow is also quite good, with a bias to blowing to the right, but the louvers work well for adjusting that.
The energy saver option is useless unless you use it while away. By starting up the fan every three minutes to "check" the temperature it is highly irritating. It should either leave the fan off or go to low speed. An auto fan speed option would be nice to have as well.
Overall it's not a bad unit as long as you can isolate the rattling and can stand the low drone of the fan motor. It seems like the kind of unit that can cool better than advertised, but there's definitely areas where it can be improved.
Honest reviews on LG 8,000 BTU Window-Mounted Air Conditioner with Remote Control
My model is LW8013ER. It took me 3 units to get one without Fan rattle and the 3rd did not last for long. Note I have a 12K unit that is about 2 years old and never had any issue with it. I tested the 3rd unit and it was fine until about 3-4 weeks then I stared hearing a rubbing noise, not a clanking noise like the first 2. After a week it mostly went away until I heard a big clank and then the fan was being blocked from running at all from that point. So called LG and gave them all the details/Serial # etc. They scheduled an appointment for Monday. Well that night the guy called my WORK number and said he needed more info and would NOT show up unless I called back. Called Monday morning, got answer service and they knew nothing about my appointment and said the guy would call between early afternoon and early evening. Never heard back. Waited another day and still nothing. On the third day I tried to call them and got nothing but ringing..not even an answering machine. So I called LG and told them I needed someone else that would show up. They seemed confused and said they would cancel the appointment. After that I never heard from the tech nor lg other than a call to know if I was satisfied. I won't go anything further as it is still on going but needless to say I am looking for another brand in the 8k unit size. Not sure what happened to LG but as some of the other posters have said, something has happened to them as they used to have a good rep.

We use these air conditioners in a our telecom huts and have had good luck with them lasting. They run all year round even in the winter. We have tried other manufactures and this one seems to last the longest.
