We've had this unit for several months, and last month our old LG Thru-the-wall unit finally surrendered after 13 years. We installed the LT1216CER just before a long, intense hot spell covered our area. We knew of the LG quality and reliability, and this unit provides great cooling.

I already have a LG 18kBTU in a vacation home on the water on the Gulf, but wanted to add a separate unit for the bedroom. This does the job. If it is as reliable as my other one it will last a long time. These units are a little noisy though.

This unit is fairly quiet and looks nice in the wall. We do not have a large home so it does not have to cover a large space but it does well cooling our first floor of about 700 sf. I love that it has a remote so we can access it from anywhere in the room.

Bought LG in wall AC 1200 BTU after our central ac gave out. Hesitant at first, never owned this type of ac unit or LG product. We were extremely happy with purchase. Easy to install, my husband did it. Quiet, 3 speeds, cooled entire family room and living room. Area of approx. 18ft x 30 ft.

This AC unit cools off our living room pretty well. I was concerned it was going to be a bit loud due to some reviews, but I find it to be ok.

We actually purchased our new LG air conditioner last fall but couldn't find anyone to install it so left it in our storage shed over the winter. Great timing- we had it installed and in three days we had several 90 degree days.

I bought the AC two weeks ago and I'm on the fifth floor of my building which is the top floor and my one-bedroom unit is wonderful it covers the whole unit with fans running and I'm very comfortable with this [This review was collected as part of a promotion.]
