  1. Velly –

    I was looking for a powerful unit that was quiet. This is the one! I love the wifi feature as well. Allows you to control the unit from an app.

  2. Amanda –

    I’m in love with my new AC. Love the app to control it. Didn’t set it with Alexa yet. I don’t see the point of it anyways. The app is very handy.
    My room gets cool in no time, Let’s see what happens when the summer comes.
    Installation was quick’n-easy.
    It is a bit noisy compared with my last AC unit, but it’s ok.

  3. joey –

    The air conditioner work is very quiet and nice work at night.

  4. wacchen –

    Bought this unit for a home office to make lock down working more comfortable as my old unit was loud and under powered. This unit cools the room quickly but is still too loud to be used while on calls. The ThinQ app is useful for cooling the room before I need to use it and checking I’ve switched the unit off.

  5. TomP –

    It’s great product Lg. It’s run nice @ smooth ,quiet, it’s not to loud…

  6. Luispenzo –

    Excellent the best purchase ever Excellent the best purchase ever

  7. Vladtvny –

    I can highly recommend this product, good quality and I like that fact that I can use Google Assistant with it.

  8. wicked –

    Very easy to install, replaced a previous LG model that molded. Be very careful to install it at a slight tilt to avoid the costly replacement I had to make.

    For some reason this one is *much* higher quality than the first 12,000 BTU unit i bought.

    My apt is sun facing and 450 square feet, this cools the entire space with no issues.

  9. Ru3124 –

    Works really well. I needed one for my living room and cools it down quick. Love that you can control it with your phone.

  10. Smokinkbbq –

    Used this for 1 season so far and it works great. Have it in a large garden room and very happy with it. Seems to be very economical to run based on my electric bill. The remote is easy to use and it cools really well for a room with little insulation and lots of windows.

  11. piv21 –

    This is the 2nd LG brand A/C I will be returning to Best Buy within a week – 2 different models. This one sounds like a piece of plastic is stuck in the fan blades. Will not be buying another LG window A/C, which is disappointing. I’ve never had trouble with LG brand A/C until this year.

  12. LlamasRFun –

    I don’t have too many complaints. I did not have issues with it connecting to my wifi and seems to work well since Beaty Buy installed. I live in a large pre-war apartment and this unit does a good job keeping my living room and separate dinning cool on the humid days we’ve had recently. I think the unit is a good value for the money but I do recommend having it professionally installed or having at least two people put it in your window.

  13. Normal1 –

    This unit on paper is 10 decibels lower than the 10,000 btu GE unit. The unit came dented underneath the faceplate on the shell of the air conditioner, but I was able to get it on so did not bother to call bestbuy (but I hope you see this).

    I am extremely happy with the effectiveness and how quiet this unit is. Highly recommend this LG

  14. LG10KBTU –

    Works well. The phone app scheduler could have a few more options for settings

  15. Jake –

    If you want a puddle of water on the floor then this AC is for you! Less than a year since I bought this AC, it started to leak water flooding my room. (many people complain about it)! They refuse to service the unit and have given me runaround for months – outrageous! Do yourself a favour and stay away from the LG products!

  16. LookintheLens –

    I have purchased 7 of these so far and they have worked perfectly. I have customized them for through the wall installations and had no problems. These are great on eco mode and use a fraction of the electricity than the AC’s they replaced. Some reviews said they were a little loud, that is not my experience. The remote control works really well from across the room. They replaced 30,000 BTU units and cool better.

  17. Legend –

    Biggest piece of junk , front doesn’t stay on , sides don’t

  18. Smith –

    Works well quiet and easy to use replaced old existing unit from different manufacture and slid right in the old housing.

  19. Acunite –

    Works good and keeps your room nice and cold on really hot days

  20. RedYoshi –

    Excellent for a living room. Install was easy and use right away

  21. forcomingsummer –

    So far soo good works perfectly hope it works for long time

  22. SlukDaddy –

    I ordered this window A/C with the highest of expectations based on the reviews. I was looking for a robust window unit to install on the first floor of my 2,800 sq ft home and this seemed to be a good choice. The first unit arrived and it was damaged (see the pics … the box was not damaged so it obviously was damaged prior to being packaged). I ordered a replacement and after installing it – which is a HUGE pain in the butt, by the way – it would not turn on. I spent about two hours going through the installation process and turned on the A/C prior to doing all the “finishing touches” (foam insulation .etc.), at which point it worked, but then when I was trying to install the smart app on my phone (WHICH YOU CAN ONLY USE WITH A 2.4 ghz NETWORK, BY THE WAY, SO THERE’S ANOTHER FEATURE I PAID FOR BUT CAN’T USE SINCE I HAVE A 5 ghz NETWORK), the unit would not power on. I ordered a replacement unit because after all this work I have to give it one more shot. Let’s see if third time’s a charm.

    Synopsis thus far: Initial quality SUCKS, the installation process is PAINFUL, the customer service (all overseas) is HORRIBLE, and I am only willing to give LG/Best Buy one more shot because of all the work I have already invested.

  23. kennis –

    this cooler is pumping out ice cubes. It really does an excellent job of cooling a large room.

  24. obie –

    Eletric issue on the control panel. installed one day and it work, then the next day the control panel was fried.

  25. Tracey –

    So far its been an amazing purchase. It is much bigger thsn I expected . It cools, it acts as a fan and humidifiers

  26. Elegants –

    It works great. The room is nice and cool. I enjoy going to bed because I can sleep throughout the night comfortably.

  27. Cooling –

    Totally met my expectation. Easy to install. Does not look too big at all.

  28. Gift –

    I give this two stars as I have to have this set at 67 and the highest fan speed it should be freezing in living which is not a large room and it’s just cool… also the clean filter came and when I pulled out to clean, it was not even dirty I brushed it clean with cloth and ran under water as instructed…but the clean filter light still stayed on…I needed to reset AC.

  29. Brenb –

    I was very disappointed that this air conditioner is broken. It did not cool- first I was told by LG, it was my outlet. I had the outlet installed which was costly and it still does not cool.

  30. WillyC –

    I cool an area of about 400 sq feet with this unit and it does a great job. Very pleased with this purchase.

  31. Apurba –

    This is a perfect ac. The sound is not loud like other brands.

  32. April –

    Zero stars. Worked for less than 12 hours and than stopped working. When I contacted LG, got the run around for 5 weeks with no resolution. Will NEVER buy from them again.

  33. Helpful –

    Unfortunately after the AC was installed, we turn it on just to try it and it work. That evening when we wanted to leave it on, it did not power on anymore.

  34. Jack –

    Garbage air conditioner this ac doesn’t circulate cold air and is a defective machine. I bought one a couple years ago and was so happy I bought this as a second one. The one in the living room works fabulously this one cannot even cool or do anything. I think the machine is defective. Now I will have to get rid of it and buy another one to replace this garbage unit. Will never buy from lg again not reliable.

  35. CarolynW –

    This has been a great AC unit for our office and runs great

  36. Unknown –

    I really like it. Good quality and I really recommend it.

  37. ICE63 –

    it works and it’s heavy and very quiet – too quiet for me, that’s the only reason I don’t like it, I’m the odd 1 that likes when appliances make noise, had little choice my old 10,000 btu quit working and all the new ones are quiet
    As for how long it will last? will see I’m a Total Tech member so I got 24 month

  38. MarkM –

    excellent product, installation was easy, and functionality is great

  39. LoriL –

    Nice air conditioner. Easy to use and cools quickly

  40. EvoDallas –

    This is a big air conditioner. But it cools my house down really fast

  41. AC718 –

    Is great i love the wifi function. I just set it and forget it lol well not forget it I don’t want to make con ed rich lol

  42. MelissaR –

    The unit itself works fine. It came with a large dent in the back out of the box as if it had been dropped. I wouldof returned it but it was soo hott i had to settle. 400$ unit

  43. HarryW –

    Very satisfied with this productvery efficient and its quiet

  44. JennyG –

    This AC is the best! I love LG Products. Definitely recommend!! My whole apartment gets so cold.

  45. JohnC –

    Received A/C unit through delivery to my door. I was not able to install it for a coupon weeks. When I finally installed it , it worked for a day. The next day I powered it on and it blew something internally then shut off and smelled hot. It won’t power back on. The return policy expired 2 weeks after my purchase and a couple days before I installed it. Best Buy will not exchange or return it.

  46. ManuelH –

    This is a great A/C! Cools our room in no time. Being able to turn it on through the app when we are on our way back home is amazing. It is not super quiet, also not very noisy, but it is definitely quieter that the one we had. And its a great value.

  47. JeanneO –

    The air conditioner is working great. The air is cold and the energy saver works. The noise is minimal. The technicians who installed it from Best Buy were so nice. I am very happy.

  48. KevinH –

    AC only used 3 times and after 3 months stopped turning on, Best Buy won’t done anything and lg said this ac needs an electrician to run a dedicated line even tho I had an ac in this same spot for 20 years. Best Buy and lg never let’s you know about this, lg says they about to change labels to state this, but no one is willing to fix or take this special ac back

  49. Lastar –

    Very unhappy with this appliance. Did not cool the area at all. We were wothe the sales rep for a few hours. We purchased two ac dehumidefier and tv mount and sound bar. Spent a pretty penny. However the sales man was so wrong about this it is a lemon. I calles it im to late. For return. So i will jave the geeksquad come out to take look. Bestbuy help.

  50. Charles –

    Quiet and powerful. Cools the room fast. Best ac unit I’ve owned. I bought another I liked so much.
