The unit was easy to install and works fairly well. I don't know if it's quieter than other window units but it doesn't seem that quiet. We live in Florida and when it's 90 degrees outside, the unit needs to be set down to 74-75 to feel cool and I used to set my home thermostat to 78. I do love the fact that if the power goes out (which ours does), the unit comes back on to the same setting. This was the main reason we purchased it. One complaint is that the "Clean Filter" light comes on often and when I pull the filter out, it's immaculate so I'm not sure why this happens. Otherwise it's a good unit and I would recommend it. I like LG products overall.
