I have used air conditioners in my home for twenty-four years and I have had the opportunity to use several different brands during that time. Each summer I place a 12,000-BTU air conditioner in my kitchen window to cool the kitchen, living room and dining room. This arrangement always cools these rooms very well. However, I still have to deal with a moisture problem because the unit extends over my deck. My old unit was an excellent air conditioner for cooling the house; but this two-year old unit always kept my deck wet. I gave the old unit to my daughter since she could use it in an area where it would drip on the grass. I then purchased the LG Electronics LW1212ER High Efficiency 12,000-BTU Room Window Air Conditioner after doing a lot of research. The cooling vents on the old unit were fairly wide and horizontal so the fan just slung the water on the side of the house and on my deck. The LG Air Conditioner, however, has slanted cooling vents that deflect the air upwards and they are narrower so the water cannot exit as easily. The fan also slings the water back into the cooling coil much better than the old unit and it has a little drainage pipe that I can put a bucket under if needed. So far so good! No water has been slung on my deck and no water has exited the drainage pipe. My deck has remained dry after using the LG Air Conditioner for two weeks! The unit is quiet compared to other brands I have used and the LG did a great job cooling my house when the temperatures hit 90+ degrees. I also like the fact that the LG uses plastic in the place of styrofoam. The foam in my other units tended to get covered with mildew and I would have to spray the foam with mildew cleaner. The plastic tabs holding the front panel on the air conditioner could be much better. I would also prefer a unit that I could install in the window without having to install the chassis first and then have to re-insert the air conditioner back into the chassis before use. But as long as my new deck stays dry I'm good!!! I'm cool!!!

Quiet and cold

I use this air conditioner to cool a very large open area comprised of three rooms divided by one open door space (880 sq ft.--den, kitchen, living room). So far, I have kept it on Energy Saver mode and low fan speed. Even on this low setting, the temperature is kept at a very cold 74 degrees. It is very quiet with no noticable vibration. All of the parts fit together tight, although some seemed somewhat flimsy at first. For those who have never installed a window unit with an outer case, this project could turn into a hastle. But, if you set aside a couple of hours to do the job right, you won't be disappointed.

Loose screws and motor mount!

Customer review by HandyB

I opened the box and took all the parts out and found 2 small screws in the bottom of the box. I wasn't sure what they were but continued with the installation. The directions and especially the graphics were substandard but since I've installed similar units before I was able to complete the installation and assembly without problem. After turning the unit on, there was a hum and nothing else. I slid the chassis out and discovered what the screws were for - to hold the the motor and fan assembly in place! To add insult to injury, the quality assurance tag was taped about 2 inches from the motor! Ugh! The mount is cheap plastic and the screws are stripped. I'm calling LG for service because my only other recourse is to take everything apart and bring it back to Walmart. Ordered from Walmart because of the home delivery option.. Oh well...

This unit was highly rated by Consumer Reports, but sold out at all local retailers including Walmart when I decided to buy. I ordered a Ship to Store purchase and was very pleased that it arrived well ahead of the promised delivery date. Others reviewers mentioned that installation was not easy and I must agree. This fairly heavy unit must be removed from the outer casing then the casing is screwed down to the window frame and then the internal works re-installed in the window mounted casing. I recommend that you allow at least an hour for this project - and have a second person available to assist. The unit does a great job of cooling - we also bought a GE 10,000 BTU unit and this LG air conditioner runs with less noise than the GE. One main drawback for those of us who may want to pull the unit out when it's time to button up for winter is that the factory recommended mounting would require removing the internal works from the casing - a reverse the installation process and a bit of a pain compared to other units that can just be removed from the window in one piece. I intend to fashion an external mounting bracket to attach to the side screws at the bottom of this unit to make seasonal install and remove easier. Overall it does a great job of quiet colling - Walmart price could not be beat.

  • A. Hi kc, Thank you for your interest in the LG LW1212ER High Efficiency 12,000 BTU Room Window Air Conditioner. Only the Through-the-Wall Air Conditioners come with a sleeve that they can slide out from and can be used as an in window if you want, you just need to get creative with either styrofoam or some effective material to close the gaps if it's not a perfect fit. The louvers for the Window Air Conditioners are part of the casing and blocking those or removing the case will cause the unit to malfunction because they are crucial to the units proper functioning...IFV
