Great Air conditioner. Cools the room in no time. Like the Energy saver.

Love it. The only thing is the energy saver comes on and off too often or it at least seems more than usual….

No problem
Air conditioner has worked perfectly since installation.

    Purchased Three LG Air Conditioners Two worked like they should the third one has a very bad noise in it. I sent a message to LG to sent some one out to pair it back in September and they said they would have a repair person contact me and I have not heard form them. So I am going to remove the unit and return it back to Home Depot.

    I’m very happy with the AC. Runs very quietly and cools the room comfortably. Would recommend to others.

    The unit wouldn’t blow cold so we pulled it out of the housing and looked like something ran the fan cover over, so the fan wouldn’t spin. We fixed it. Would have brought it back but had to get my refrigerator back running.

      Very pleased with unit; easy install and cools very good. The wi-fi enable feature is awesome; it can read room temperature and auto turn off when set temp is reached.

          AC works fine but I will NEVER, I repeat NEVER, order anything from Home Depot online to be delivered. WORST experience ever going back and forth between Home Depot and FedEx.

              Incredible. I live a small TX costal village and the AC was delivered right to the front door and quick.

              Returned the unit because it froze into a SOLID block of ice!! Additionally it had a dent in the side of the case that must have come from a fork lift

              The unit use the condensate to splash onto the heat exchanger. That would be okay if the water didn't leak from that pan and run into my electrical outlet! When I drain the pan with a hose, the unit isn't as efficient. Certainly not 14000 btu

              Leaking right out the box, only pushed hot air
              Got this new to replace the previous model (which broke down after a couple of years, thought it was a fluke), but this newer model did not work out the box. Bad product with old technology, and loud. GE is a better option because it is smaller and quieter for the same BTUs.
