Rated 4 out of 5Â by Kiran Easy to install, kinda loud, very cold
I had a 10K BTU portable that just couldn't cut it for the room I was trying to cool, so I decided on this LG 12K BTU unit. It was pretty easy to install, even by myself; took less than an hour and I took my time. It no doubt can cool. The first evening I experimented and set it to 65 and in an hour it was -cold-. It is far and beyond more efficient than the portable, and even uses less electricity. (The portable was rated at 11.5 amps.) This is a big unit, and it's pretty loud, even on the lowest fan setting. Plan on putting it in the window furthest from where you'll be sitting/sleeping. The energy saver is a nice idea, but I find it annoying as the unit turns on and off every 3 minutes. It's also rather optimistic about the room temperature. It detects the room temp from a sensor in the front grill where the air is being sucked in, but as the unit cools and that area gets colder (the condenser is immediately behind it) the sensor seems to be picking up the temp of the condenser coil more than the room temperature. It will reach 72 and turn off the compressor, then the temp at the grill will rise again, until the compressor turns on again. So while it thinks the temp is swinging from 72 to 74, the room is actually staying about 75. I may experiment with moving the sensor. I also thought this unit came with a arm/brace for mounting it in a window (as I believe other LG units do) but it does not. Turned out I didn't need it anyway. Overall it's a beast and will cool very well.

I needed to find an A/C unit that pushed 12K BTU or larger, but could still fit into a standard window; specifically the height (<16"). This was the only unit I could find that met the criteria. Based on the height requirement, I needed to remove the lower window (standard double-hung style). That gave me the 16" opening I needed for the unit.
Installing the unit would be easier with two people due to the weight and bulkiness. You have to remove the outer shell and front panel from the compressor, coil and electronics. It comes out like a dresser drawer, that sticks; so having a helper will make that step much easier. Now you have a fairly light shell that you connect the side curtains to and fit into the window opening. The key part is the adjustable brackets that connect to the bottom of the shell and your casing or brickwork. These brackets will hold the majority of the units weight, AND provide the appropriate angle (front to back) and leveling (side to side).
At this point, the instructions call for putting in two retaining clips. They provide a warning that the tabs easily break so install them according to the instructions. Unfortunately, the picture(s) in the instructions are almost useless. They are too small to see which direction they are supposed to go, or even where they specifically go. Their instructions, in general, are poor. They use different names for the same parts in different sections, and, as noted above, the graphics are too small, blurry, and far too few for something that has a number of step-by-step instructions.
Based on the style of your window (my double-hung casing has almost 2 inches of thin edging), you may want to reinforce the bottom. I added a couple strips of 1"x1" under the unit, to provide a solid stable base, and give a tight connection for the curtains to be screwed into at the bottom. The top of the curtain is screwed into the frame of the upper window.
Now that the shell is firmly put in the opening, the guts of the unit need to be slid back into the shell. This is another step that is easier with two people. Once you have the unit's base lined up with the rails on the shell, it slides in easily. It is critical that the leveling brackets be installed securely and ready to bear the weight of the unit. If not, you could possibly damage your window or its' casing; or worse, have the unit go right out the window! I also added a piece of 1"x1" with "L" brackets across the top for stability and security. Any air-gaps were filled with insulation.
The instructions mention having to pull out an adjustment arm behind the electronics. Again, there wasn't a picture for this step, so it was unclear what to do. There is a plastic arm that looks like it may open/close a small vent near the fan, but the instructions do not say when or why you would open or close the small vent. It also looks like it is supposed to provide a single handle to move the air direction louvers left and right. Unfortunately, the fragile plastic connector between the louvers was missing on the left side, so I have to manually turn 3 of the louvers manually with a pair of needle nose pliers - no biggie since once you set them, there isn't much need to change their position. Also, since the instructions don't specify what to do with the plastic arm, if you pull it through the louvers, it prevents you from moving the louvers up and down.
Lastly, you put the front panel and filter back and put all the screws for the shell back. I find the way the front panel connects is also poor. It has tabs on the edges and two recessed screws. The front panel [on my unit] appears to be slightly warped, so it does not fit smoothly. For the recessed screws, have a magnetic-tip screwdriver in your tool-bag since you need to hit the center of the recessed hole.
So now the unit is ready for operation. I have had the unit running for about a month and I am VERY impressed. It is very quiet and puts out very cold air. Using an HVAC thermometer, it consistently puts out air 20 degrees below your set value (Example: if you set the AC at the lowest temp, 61deg, the air temp generated by the unit is 41deg). I use the energy-saving mode most of the time. Once it reaches the set temperature, the unit will kick-on a "low fan" to maintain the temp, or when needed (lets say someone opens a door and lets a lot of hot air in to the room) it will boost to a "high fan" if it detects a significant difference in temperature.
The only issue I have had in the month I have had it running, it the "clean filter" light came on. I pulled the filter and it looked clean. I did a quick vacuuming of the filter and the front panel anyway. Again, I had to pull out the instructions to find out how to reset the filter light. You must press the up and down temp arrows at the same time to reset the light (not the most intuitive way to do it).
This AC is cooling a 24' x 20' open family room, that has a bedroom off one end that is 14'x14', and a 4' wide hallway at the other end that leads to 3 more rooms. Even when the kids leave the other doors open, this unit maintains the set temperature.
The only task I have left to do is to build an insulated box to enclose the unit during the winter; as I would rather leave it in place, than remove it during the off-peak months.

Rated 1 out of 5Â by dissapointed Looking forward to a cool home and...
I assembled the frame and secured it into the window, then slid in the LG 12,000 BTU unit and expected nice cool/cold air to flow from the unit . Nothing resembling cold or cool air has blown into my home. I reviewed all the potential issues and there is nothing but outside air temperature air flowing from the unit. So my home is still the same temperature as outside with no cooling whatsoever. I purchased LG vs Frigidaire at Lowes due to my trust and experience with Home Depot, but I am getting flawed products from Home Depot more frequently and I do not have the time to keep running back to a store to return or swap. Plus the A.C. unit is fairly heavy to run back and forth.

Rated 4 out of 5Â by Muck 429 This product met all of our expectations and more.
My wife and I have been enjoying this air conditioner and still have it installed in our window. We use the fan mode often. We also love that it alerts you to clean the filter, which is a very simple thing to do.

Rated 5 out of 5Â by Kozysweetkiss Excellent for the price
My small window air unit gave out. So I bought this Lg. I am glad I did. Love the temp feature the fan speeds and the timer. This unit also tells you when you need to clean the filter. I would buy it again.
