I was looking for a small window unit to assist my central air in an office that had a lot of computer equipment putting off additional heat. It was routinely 10 degrees warmer in that room than anywhere in the house. I liked the features and price of the LG unit and I could not be happier. It was extremely straightforward to install - maybe an hour or so. It works precisely as I would have hoped. It's a touch loud when the compressor runs, but I'm not sure it's more or less than any other comparable unit. All in all, a great purchase.
