Rated 4 out of 5 by from Problem solved! I live in northern Michigan in an 800 sq. ft. cabin on a small lake. Michigan summers here can be pretty brutal when it comes to heat and humidity and down right uncomfortable. I installed my LG LT1216CER Air conditioner in a new LG AXSVA1 26 In. Wall Sleeve for Through-the-Wall Air Conditioners and I have been comfortable since. The installation was pretty simple and the entire cabin stays cool and dry.

Rated 4 out of 5 by from Works well I bought it for my 2-car garage and it is quite effective, lowering an extremely hot place, at times, by 5 to 10 degrees. Plus it does take humidity out of the air. My garage is now a place I can work in (on occasions) without streaming perspiration.

Rated 4 out of 5 by from Superior Cooling Ability I live in a "small" house, under 450 square feet. Unit is powerful enough to easily cool living room, kitchen, bedroom, bath and hallways with the setting usually no lower than 74 degrees even on the hottest days. The energy saving feature is wonderful. The unit is however somewhat noisy, but that could also be because of the size of my place. My friend who also lives in one of these small houses installed one as well and is equally pleased with the unit. Would highly recommend to anyone looking for an attractive, efficient, and well-constructed air conditioner.

Rated 5 out of 5 by from New unit for an existing through the wall hole Unit is running great, it is cooling the main living area of a 1,500 sq ft ranch home. We are extremely pleased with how close the measurements were in the online spec's and the included material to help insulate fill small gaps was a great help to us. The existing hole that we have has existed for decades so trying to find a unit that was close to our existing hole was a big deal. We have had to turn it off on occasion as it gets too cold (shows that it is working great so far). Manual/instructions that were included were fair. Some slight improvements would have helped me a bit, but nothing that I could not overcome.

Does this unit drain out from the back like most A/C units? I don't see where the condensation drains out. Where does the condensation go?

Asked by: Jwhite80
The ENERGY STAR® Qualified LG 12,000 BTU 115v Through-the-Wall Air Conditioner, Model # LT1216CER has to be installed with a rearward slope for draining. Water may be collected in the base pan in highly humid conditions or on rainy days and when it overflows, it will drip out from the rear of the unit...^IFV

How come my lg air conditioner dose not get cold and why were we told by our manger not to put it under 70

Asked by: Jrod07
We regret the trouble you have experienced with this air conditioner. If the device is not cooling, it is first recommended to ensure that the air conditioner is plugged into an appropriate electrical outlet, on a dedicated circuit, which can support the proper amperage for the machine. Second, it is recommended to check the air filter to ensure no obstruction in the air flow. We would not have a reason why you were told not to put it under 70, it would be recommended to speak with the manager. If this does not resolve the matter, please contact our Customer Interactive Center at 800-243-0000.

Should the unit be set on cool or energy saver

Asked by: Sieben
We do appreciate your interest in this air conditioner. There is not a recommended setting as it depends on personal preference. With ENERGY SAVER, the fan stops when the compressor stops cooling. Approximately every 3 minutes the fan will turn on and check the room air temperature if cooling is needed. While in COOL, the compressor runs and cools the room.

I have this unit the LW1216ER bought it from Home Depot. It works great I notice the huge difference between regular normal room air to this cold refrig air.  Is it normal to have water on the back side in the inside ?? Just wondering? thanks 

Asked by: Darren1988
We appreciate your interest in this air conditioner and its operations. Yes, it is normal for water to be collected in the exterior portion of the cabinet. This is condensation based on the outdoor humidity, as well as on the operations of the compressor and sealed system.
