What people are saying

Rated 5 out of 5 by from Great Cooling I've only had it about 3 weeks, but it's made a world of difference in my place... the cooling effect is great and most welcome and, I should add, much needed. Glad it's here. Looking for many years of cool comfort.

Rated 5 out of 5 by from Fully satisfied I bought my LG unit a month ago and couldn't be more satisfied. It performs exactly as advertised, cooling the room quickly and efficiently. I am happy I purchased it, and the rebate received made the price even better.

Rated 4 out of 5 by from Works well but some parts not very durable We bought this to replace a very old wall air conditioner. The first one that was shipped to me was damaged so badly in shipping that it would not work. The second works fine - cools well - relatively quiet - controls easy to work. However this one was also damaged in transit - the catches for the filter cover were all broken when unpacked. At this point I can tolerate no further delays so we will use as is and hold the cover shut with tape.
