    • Big Home & Cools My entire downstairs
This unit has the capability of doing a huge area. The 3 fan speeds dictate how much you need or want to cool. The F1 speed is whisper quiet and even with it right in back of me as I'm watching tv it does not interfere. F2 and F3 can be a bit noisier than I like but in trade, it's doing the job well. My Great Pyreneese gives it five stars. She lays in front of it curled up like a big pillow. Overall, I am happy with my purchase. It's heavy at almost 100 pounds and generally requires a tow man lift unless you can lift that kind of weight. I highly recommend the unit. I can only imagine the job it would do in an apartment. ... show more

    • Great AC
This is a powerful and extremely quiet ac unit. Had a problem with my first one where the fan attached to the motor must have been slightly bent and it created a loud humming noise that was annoying and could possibly shake the AC out of the window. Contacted Amazon and they shipped another one immediately and just had to box the old one up and send back. Installation is definitely a 2 person job and that’s coming from a larger man. It is just too large and awkward to carry alone unless you have a 7 foot wingspan. ... show more

I expect to install a window A/C unit. I do NOT expect to have to fully assemble the thing. Like physically pull the A/C body out of the housing to setup. Between the cheap plastic clips that do not fit where they should clip in, curtains that don't line up, screw holes too small, not too mention the damaged fins on the ac unit makes this probably the biggest waste of $600 I've personally thrown away. ... show more

    • Great AC and it's soundless!
What a surprise! It is basically soundless AC. We just installed it yesterday and had a deep sleep not even recognizing that it is running. Another positive side of this AC, the quality of air. It's fresh, no smell of working AC, and easy to cling removable filter. The size was scary... but when it was installed, its looks clean, simple and modern. We love the new LG AC! Highly recommend. Requires 2 people to install the unit. ... show more

    • Great AC - but a pain to install. Great AC - but a pain to install.
Review Image by Robert
Right off the bat, this would be a 5 star review if not for the installation process. Laying the box flat you'll take out the front clip of the unit and become aware, this is not an open the box and put it in the window unit. The instructions have you remove the main unit from the casing. Then install the casing to the window and slide back in the actual AC. That part isnt difficult. The difficulty comes when trying to install the black clips that support the sliding sides... they just are not built to go in. I had to use pliers to bend parts of the casing in order for these clips to pop in. You also will likely want to get a support for the outside, as its pretty heavy. The sill supports provided dont work if you have slanted sills. I ended up putting a support rod in from the end of the unit to the ground. The actual AC once its installed is GREAT. Its VERY quiet at full force, and pushes the air very well. ... show more

    • over one year later... and still incredibly impressed!
over one year later... and still incredibly impressed! I bought this for a sunroom where my large dog stays during the day (reference, it has to survive the Georgia heat). This AC is so efficient and gives me such a piece of mind to hook to my wifi to make sure my pup is ok. It honestly keeps that room cooler than most of my house and I did not see a big difference at all in my power bill. I will definitely by again if needed. Perfect value, perfect functionality, and amazing cooling ability! ... show more

The box wasnt damaged so I assume LG packed this AC is this state. Outside of the fins being bust and the white substance (corrosion?), its a good looking machine.

    • After a year still great.
I bought this a year ago may. It replaced an AC unit that was in my house 30 years ago when I bought the place. This unit is super quiet and the 12000 btu cools the 12 x 16 room its in pulse the adjacent dining room 12 x 12 with very little effort. With a fan in the hallway it helps the bedrooms a fair bit. Not bad for $500. I rarely put it on the 2nd setting. Hope it lasts as long as the other one. ... show more
