Perfect For Me


All of the features I could ever need. Cools a larger area than expected.

Nice AC--A bit noisy and difficult to install


We hired the same man to install this air conditioner as we have for others we've purchased. He said this was the most difficult installation ever. The directions were impossible. The AC puts out a lot of really cold air (that's what we wanted), but it...

Excellent buy - super cooling


Replaced our 4 year old Samsung units that was also 11,500 BTU. This LG unit is extremely quiet over the older unit and cools the rooms almost immediately. We have the a/c on low and it out performs the old one on high setting. Extremely pleased with...

Good but expensive...


It works great, installation was pretty easy. I wish the timer function worked differently. I would like to be able to set a start time, not by number of hours. Like the energy save function.

I've had this AC for nearly 2 months, and it performs worse than the 40 year old AC removed. The old one worked - not good - but it worked. This one recycles over, and over and over all day long, and it never reaches the temperature that I've got it...
