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, we're surviving a summer heat wave and having to turn UP the temperature because we're 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.
