I bought 0.75 LG LWA2CP1F window AC for my father’s bedroom about 2 months ago. In starting the AC gave some problem of loud sound during running and I had to contact the person who installed it and he came and resolved the loud sound problem because there was some error in installation. Since then there is no problem and the AC is giving good cooling and running properly.
There is a good feature of auto shut down specially useful during night, the AC will shut down automatically after you set how many hours it needs to be run like 1 or 3 hours. So till now I am satisfied with it.
