Customer Product Reviews

Rated 4 out of 5★ by 63reviewers.
Rated 4 out of 5★ by Very Hot and Humid Summer so far in Florida Bought this unit at Home Depot to replace same looking non-working (age unknown) LG unit at new apartment.Have this in for about a month, and it cools down my apartment very quickly. The humidity level is also acceptable. I love the energy saver mode, it's like having central air!So far, working great. 07/17/2012
Rated 5 out of 5★ by Excellent product I purchased two of these window units in April of 2012. I live in the heat and humidity of Florida, so they have gotten a good workout over the past two summers. I need to replace my central system, but because these work so well, I haven't been in any rush. My home is 1,388 SF and the two units cool it easily to 75 degrees. Once I turn them on in the spring, they are never turned off until fall arrives. They are running now at the end of the second summer. Not only do they do a great job, but my utility bill is about $50 less each month than it was with the central unit. The only negative I can think of is that some would consider them a little on the noisy side. I sleep with one right near my head. At first it bothered me, but soon became "white noise" and I don't even notice it anymore! I highly recommend! 10/05/2013
Rated 4 out of 5★ by Installation could have been better designed. I am happy with the functioning of this unit. I was disappointed with the instructions and the actual process of the installation. The screws provided were for the most part hard to fit. Seems to me more care could have been used in designing the installation process. Like self tapping sheet metal screws.The video makes it look easy, but it took me almost three hours to install. (I am a building contractor.) The printed directions were too small to read easily and were not easy to comprehend. 06/04/2014
Rated 4 out of 5★ by works well I havent used it to much but when i have has worked well. Was damaged in the back when i took out of box. Wasnt that bad that i would have had to take back. 06/06/2014

Rated 5 out of 5★ by Very good works great Works great an great price installs like larger a/c unit but over all was not hard. Very quite an smooth start up. Way to go LG great product. Also has a drain unlike the last unit this one replaced. 06/27/2014
Rated 5 out of 5★ by Great a/c! We replaced a 220 unit with this 110 in a 14 x 25 room and it keeps it colder than the old unit. Not only would I recommend it, I will be purchasing 2 more!! 07/13/2014
