  1. MsHawk

    Very nice air conditioning unit. Came quickly and set up was easy.

  2. KDR220

    This Air Conditioner works fantastic and as advertised. It cools the entire main floor of my home which is exactly what we were hoping for

  3. JoeJ

    Puts out more cool air than I expected. Very pleased.

  4. DONTOGOTALG

    We Love This AC Unit!
    Really Cools Down Our House!
    Reno Can Get Nasty Hot In The Summer! No Worries With This Big LG AC!

  5. MrsV

    This air conditioner doesn’t stay cold. The compressor turns off way to fast and doesn’t come in for a while leaving you with semi cool air that doesn’t feel ideal while sleeping.

  6. Stolen

    Never got to use it, it was stolen before I got too.

  7. Betty

    This window unit is actually quieter than I thought and it keeps my living room cool. I give it five stars.

  8. Walter

    I bought this air conditioner about a month ago and it cooldown really good

  9. Moreno210

    Omg it blows so good. Don’t like the loudness of the on and off when it’s on energy safe mode but over all a great AC

  10. DeeB

    We installed it and it never turned on. Now I’m having trouble with retuning and replacement.

  11. KWHint

    Puts out good cold air, not too many frills, which I wasn’t looking for..

  12. ShaunMidwestUSA

    Works wells to cool a large space – including a combined dining, kitchen, and living area. I am waiting for my electrical bill to see how much energy I am using to cool my space.

  13. Miguel2005leon

    Purchase the window ac, and it works amazing. The installation was very easyand self explained. You definitely need two people to work on this while installing it.

  14. GroguOP

    Very Solid Ac so far. Just wish the Remote had a bit more Range.

  15. MonTech

    The installers from Total Tech did a fantastic and speedily installation with excellence. Explained how to use device and informed me on heaters that would be good too. Excellent service Total Tech provided for this installation of AC unit.

  16. Dustin

    Works just good enough for 600 square feet. Not as good as advertised

  17. JDLC

    I have had this AC for about 2 months now. It is great at cooling the entire space quick, and I love the ability to control from my phone. The only con is that it is a bit loud but not so much that it won’t let me sleep.

  18. Tony

    The A/C came in perfect at the time that the I.E. was experiencing high levels of heat. The LG kept our whole living room cool.

  19. Good

    Great unit. I love it. It’s a little loud but that’s not a problem

  20. CharlesC

    Just got my AC yesterday and boy o boy its nice..I love the fact you can set it up to wifi and control it.Its a powerful unit which is needed in those hot summer days ahead..Its a big unit so you need two people to lift it.Set up was a breeze. Thank you LG for this great product.

  21. Curt

    We have a very large master bedroom, this A/C cools it down very quickly, and will keep it cool. My issue is that it is loud. We live in the country so we’re used to being able to hear a pin drop in the middle of the night. This A/C is loud, so it’ll take some time getting used it. The unit is BIG. Make sure you measure everything before you purchase, and I recommend you get something that goes in your window to hold it up. I would not recommend relying on the window frame strength to hold this unit up, you may find your AC on the ground in short order if you have modern windows designed to “pop out” for easy cleaning. We tried the “eco” mode, and all it did was wake us up all night when the compressor kicks on. In this mode, it seems to ride a fine line on the temp control, say maybe .2 degrees. For example if it senses the temp going up .2 degrees the compressor comes on, then the temp goes down .2 and it shuts back off. Very annoying if you’re trying to get a good night’s sleep. But, with all said and done, instead of sweating bullets, this AC keeps our very large bedroom cool (over 400 sq feet).

  22. KareemH

    Powerful. Not super loud. Its probably overkill for my living room (its spacious but not huge) and works pretty well. Clean the filter often because if its not clean it loses power.

  23. NatalieG

    Works amazingly well. Keeps most of our main floor cool

  24. Unknown

    Excellent!!! Best Buy is my favorite electronics store, i’m going to be a Best Buy customer all my life.

  25. MeilingL

    Don’t order AC in the busy summer, I guess they are too busy so sent wrong AC to me. I was forced to use it because I paid for 2 guys to install AC for me the same day as it delivered.

  26. NicholeT

    It’s an average unit. Randomly shuts off in the middle of the night (every night) and the warmth in the room wakes me up. That’s annoying. It changes settings whenever it wants basically. My master bedroom is about 600 sq ft and it keeps it cool, but not cold which is a bummer for the price and description. I wouldn’t buy again nor recommend.

  27. Tweety

    This cools my whole house. It is almost 2000sq. Ft and works great.
