I've had it installed for two weeks and it works fantastic. I live in AZ and it gets really hot here, 7 of the last 15 days have been over 100 degrees. I leave it at 77 on Energy saver most of the time, and it's already saving me over 25% on my electric bill compared to the competitor AC I only had for 4 yrs before it started acting up. 

This one blows cold and nice and it's very quiet compared to 3 other brands I've had in the last 8 years. 

I don't usually get caught up in raving reviews, but I'm thoroughly impressed, and this 10K AC is doing much better than my former 12K in a large room. Just get one if you are looking. 

Oh, I also liked the two-piece install, the shroud mounts in the wall/window first, so very easy to simply slide the works into that and put in two screws and done. 

I'm looking forward to a much more comfortable summer this year with the LG.
