Review on Efficient Cooling and Heating Solution: LG LT1237HNR 11,200 BTU Heat Air Conditioner, 12000, White by Tina Pagan

I bought it to replace an old unit, so there was already a hole in the wall. I also received the LG case that comes with this device. It's VERY tight in the sleeve. And the block sticks out about 5 inches from the wall. And that, although the device is pressed completely against the grate. The instructions leave a lot to be desired. For example, the placement of some insulation strips is confusing. The plastic rim around the sleeve is so tight that it doesn't stay flush with the wall. While working, he still kept a cool head in the 325 square meter room. It was installed in late spring so I haven't started heating yet. When the compressor runs, the block/sleeve rattles and it's a little louder than I'd like. But it's not in the bedroom or TV room, so noise isn't a big issue. As long as the pleasant comfort in the room is maintained, I am basically satisfied.
