Rated 4.0 out of 5 by 105 reviewers.
Rated 1.0 out of 5.0 by No Freeon??!! We had the same experience as Anonymous from Denver. Installed the unit and while the fan worked, the unit was not cooling. Called Home Depot, who called LG, who sent a service tech. We were told the unit had no freeon, so it either leaked or was never installed at the factory. Waiting for UPS to come so that we can return. Not impressed! May 28, 2012
Rated 5.0 out of 5.0 by Mr. BINGO ! The best air conditioner. April 26, 2012
Rated 5.0 out of 5.0 by Easiest Installation I've ever seen. I have two of these AC Units. The first was purchased last summer, and is still working great over a year later. I am pleased with the cooling capacity, noise level, and energy efficiency. I have not scientifically measured the efficiency of this unit compared to others, so that is why I rated "Energy Efficiency" at 4. My electric bill is not bad, in spite of massive heat waves. The installation of this AC unit was a breeze. The actual AC unit slides into the metal shell frame, which you mount in your window first. That means no having to balance a heavy item while trying to secure it. Just install the light-weight shell in your window, make sure it is secure, and then slide the actual AC unit cleanly into place. There are two adjustable feet on the frame that are well balanced with the unit's center of gravity, and easy to adjust. On my window, I had to use a 3/4" board between the brick wall and the adjustable feet, but in a frame house, I imagine the feet would hit the outer ledge just fine. I found the frame to mount very securely in my window, and because there are two feet (on either side), the whole thing is very stable. So, except for a small board I already had laying around, everything I needed was in the box. Note: A normal "AC Window Bracket" will not work, or be needed with this unit. Two adjustable feet will be able to make secure contact with your outer window frame. Because you can access the inside area of the frame (with the AC unit removed), this product would lend itself to be installed in a variety of conditions that normal one-piece units could. When just the frame is in the window, you have complete access to the inside of the shell, and therefore could fabricate any number of ad-hoc mounting solutions your situation may require, such as additional security from the side-an ideal solution for ground-level urban environments. No matter where you install this, be sure to block the top of the window from opening. I used screws on the inside edge of the window track to prevent the window from being opened by accident. Tip: Have open-ended wrench of the right size handy before you begin. Make sure you have a grounded 15 Amp outlet near the window. If you must use an extension cord, do not use a power strip, use an extension cord made for air-conditioners. July 10, 2012
Rated 5.0 out of 5.0 by Awesome Unit -Easy to Install We have central air in the house but since it has been in the high 90's going to a 100 this upcoming weekend - we got this to help out the main unit since it runs constantly from 7am til 8 pm and the house was only cooling to 77 and with temps in the 100's I'm guessing it will be in the 80's in the house.. I like the fact it is a pull out unit - meaning you can install the frame in the window, get it all secured - then slide the main unit in. Its quiet for a 12,000 BTU unit and has cooled the living room, dining room and kitchen off nicely. We have a 1,600 sqft ranch house and its working as a supplement to the main central air very nice, and the price was very good for a 12,000 unit. I have 2 other LG units at my one rental property and they both work great. July 1, 2012
Rated 5.0 out of 5.0 by Great Unit - Installation was easy I researched Consumer Reports before buying.This unit was rated best of all in the 12,000 BTU category. The chassis slides into the frame like higher priced products and installation took about 40 minutes. It's not any louder than a fan and it cooled the room down 20 degrees (from 95 to 75) in one hour! I highly recommend! May 28, 2012
Rated 5.0 out of 5.0 by Quiet, cool, efficient We've had this as the main a/c in our living room/kitchen area for 2 years now, about 600 sq feet. Installation seemed pretty straightforward, but I've put in a number of window a/cs. It is a lot cheaper to 'zone cool' with window units than to use the central a/c to constantly cool rooms that aren't being used. Even in the hot NC summers, our electric bill rarely exceeds a hundred dollars. It seems wasteful and unhealthy to set an a/c unit below 70 degrees during the southern summer (come on, if you like it that cold, move north). Ours is usually set at 72 (the real temp in the house stays around 75 at this setting). It's quiet, reduces the humidity to nothing, so between it and the ceiling fans, it's real nice. On weeks like this, when the temps are in the 100s for days on end, it runs non-stop, but so did the Frigidaire 15,100 BTU a/c this one replaced. They both seemed to produce about the same level of cooling, the the LG is much quieter, and obviously takes significantly less power. We're very pleased with it. June 28, 2012
Rated 5.0 out of 5.0 by Awesome AC I love this AC. The 3 speeds actually result in lower noise at the low setting. Cooling is great. Installation is a breeze, since the unit will slide out of the case. Quality is top notch. Vent direction works good. Also, this unit makes use of the slinger fan which throws excess water at the cooling coils to increase efficiency....make sure you tilt it back a 1/2 inch from level to make use of this like the directions say......do NOT drill any holes to drain the water....here in Palm Springs there is NO water that overflows.it all goes to cooling the coils and evaporates there..............z October 23, 2012
Rated 5.0 out of 5.0 by A little slice of heaven Our central air has been nothing but, trouble since it was installed about six years ago. It's busted again. I decided that I need to do some shopping for a new system. In the mean time we're having record highs. It's supposed to be in the 90's and humid tomorrow. So, my willingness to suffer through it has worn thin. When I brought this unit home it was 84 in the cool end of my house. The instructions are OK. You'll probably have to make some things work for your windows. But, it installs easy. I got it installed by myself. There is a little heavy lifting but, install the cabinet and then slide the heavy part in. It starts making cold air right away. Right now I'm loving it. I don't expect this unit to cool my whole house but, right now it's obvious that it will make life much easier downstairs. This unit has bought me some time to shop around for a better central air and furnace. It makes gobs of cold air. It's reasonably quiet. The function and finish is good. If the HOA doesn't say anything I'll try to leave it in place all summer. I purposely installed it in the back of my house so, it's not visible from the street. You just don't realize how much AC means to you till it's hot outside and your AC is out of order. May 2, 2012
