Perfect for our 2 car garage!
This AC unit is great! I love that it has a remote. It keeps our garage cool while we're working on a project. It's not too loud. Installation was easy. It has efficiency settings.

poor quality control
spent a couple of hours setting up the unit only to turn it on and find out that the a/c did not put out any cold air and the fan only worked on high.
returned for a unit from another mfg that worked!

Keeps our dining room nice and cool
So far I have loved this LG Smart window air conditioner! We set it up in our dining room so we could finally enjoy some cool air while we eat in a hot summer day (I love having coffee for breakfast!). It’s cool the room within an hour and stays cool, also the remote comes in handy so you don’t have to constantly get up to change the speed, temp or setting. It is big so...

Amazing
I have always liked LG Electronics, and I have to say this air conditioning unit is very good. Installing it was easy, so anyone can do it. Once I started using it, I was happy to find it is very quiet and does not bother my home. It cools the room really well and works easily. The remote control is also very helpful because I can change the settings from anywhere in th...

Works well
Standard design AC. Noise level was typical for a window unit. Install was standard. Not sure energy efficiency just yet. Overall it performs as expected so no stars were deducted.

Cool and convenient!
Nice air conditioner!! Living in a city that gets high humid temps some days, a good AC is essential! My livingroom is approximately 15 x 20 and it cools it down pretty well! I love that it has a remote, because who wants to get off the couch every time you get too warm or cool? Even on the highest fan level, it isn't too loud. I personally love the background noise of ...

Very compact
This window unit is a lot smaller in dimensions than I expected so instead of using it in our garage, we will be using this into the finish room of our new home since this will work perfectly because of its size. It’s pretty straightforward and controls are available on the unit itself with the remote as added convenience. Connects to the WiFi and status are all indicat...

Chilly
It came at a perfect time for the hot weather. We do have central air but out back room that we’re converting to a bedroom gets very warm and the main unit doesn’t reach it. This has made our night so much more relaxing as we sleep hot and wouldn’t survive without this. The remote control is convenient for late nights when i don’t want to get up

Great conditioner
Great LG air conditioner! It's perfect for vertical windows, although it might not be the best fit for horizontal ones. I'm really impressed with how quiet it is and how quickly it cools down the room. I’m very glad having it for my living room instead of using the central air conditioner! Saving lots of energy! Highly recommend!

Best AC for summer time!
I’ve been using the LG Room Air Conditioner for a few weeks now, and overall, it’s been a great AC. It cools the room quickly and efficiently, even during peak summer heat. The unit is relatively quiet for its power level, making it comfortable to use during the night without disturbing sleep.

Sleek with fast cooling!
This is an excellent window cooler. It will cool roughly a 18 x 25 room, and the lowest temperature it will go is 60 F. There are 3 different speeds you can select and cycle from. The remote is super convenient and comfortable to hold, and easy to read! The box states this unit will also auto restart after a power outage, which we didn’t get to test. Overall this unit ...

Quiet & efficient
I did take this out, install and use for a few days that it got warm here and in the time I got to use it, it is the best window unit I've ever owned. Easy to install and cool room quickly and quietly! Seems to be much more energy efficient as well, since it cools without overvworking it. Love that i can controll from my Google or app on my phone and turn on from anywhe...

Cools Fast with Smartness at Your Convenience!
I must say, I'm impressed with LG! I've never had an LG air conditioner before, but I'm so happy to have one now. We decided to put in our frog room. It was a pretty easy setup with clear instructions given. The cooling capacity is so amazing! It cools the room within several minutes, and it puts out so much refreshing, cool air. The 4-way air deflection is convenient f...

Brrrr
This was perfect timing because I have another brand that has been replaced twice. This one is easy to install. It gets very cold and is quiet. I love having WiFi and the app on my phone. I can control it when I’m not at home.

Powerful but quiet unit!
This unit is a beast! It cools a room so fast but it’s not overly loud like most ACs. It was very easy to install and I love all the smart features it has. The washable filter is awesome for keeping up on dirt to prevent mold

Get it!
The LG 12,000 BTU energy efficient window air conditioner works great. When it's running, you can barely hear it, which I love! It came with everything you need to install it which was pretty easy to follow and install. You can also control it from an app on your phone, the remote, or on the air conditioner it's self. I absolutely love this air conditioner and highly re...

Easy to use
I bought my air conditioner 2 weeks ago. I am very happy with it. It works so much better than my Fredrich air conditioners. Within 5 minutes it cools my living and dining room.
