What people are saying

Rated 1 out of 5 by from Great till it broke Worked great for 4 months then the compressor would not shut off unless you unplugged it. So push the power but and everything cuts off but the compressor. Currently I am in contact with the warranty department and they are working with me to resolve this issue. That being said save your receipt just in case. I never expected this from an LG product

Rated 4 out of 5 by from Does a Good Job I bought this a couple months ago and paid for professional installation (which was super great). It was OK, but the vent wouldn't adjust down and was blowing the cool air up to the ceiling. Put in a repair call, and the repair was made but still doesn't adjust like I would like it to.

My unit is about 3 years old and has stopped cooling. It sounds like the compressor is running. Is there a way to recharge the unit? What is the life expectancy of this unit?

Asked by: Roselani
The refrigerant for the LG 12,000 BTU Window Air Conditioner, Model # LW1216ER is in a closed system and the only way it gets depleted is if you have a leak in the system. If there is a leak in the system, you would definitely know because the refrigerant has a very distinctive, unmistakable odor. The most likely causes for the unit not cooling are a dirty air filter or dirty evaporator coils or condenser coils. When was the last time that you had maintenance done on the unit to have the evaporator coils and condenser coils cleaned? Windows air conditioners can nevertheless be recharged with refrigerant. This unit uses the R32 refrigerant and when recharging refrigerant, the refrigerant should not be mixed since no machine is designed for mixed-medium refrigerant. If a device is low on refrigerant, the pressure will be too low and the machine won't work. If a device is overfilled, the pressure will be too high and the machine won't work either. For this reason, it's crucial to get the pressure right when adding refrigerant as not to overfill the unit...^Ivan

Can the LG 12K window unit be installed withour buying a window bracket kit?

Asked by: ellieplum
If you are inquiring about a security bracket that goes around the air conditioner, the need for one will depend on your local building codes and whether you live in an apartment building or a house. The LG 12,000 BTU Window Air Conditioner, Model # LW1216ER comes with a window installation kit that is required to install the air conditioner in an appropriately sized single-hung or a double-hung window. Some areas have codes that require a security bracket to prevent the air conditioner from injuring people if it is installed in a window that overlooks a sidewalk in the event that it falls out of the window. You will need to check with your superintendent if you live in an apartment building or check your local building codes or consult with your local building inspector...^IFV

Does this unit have a drain plug in the base pan?

Asked by: Tiann
This air conditioner is equipped with a slinger fan. The fan has an outer ring that runs in the water that collects in the base pan if it gets deep. That condensate is then picked up by the fan and expelled through the condenser, making the air conditioner more efficient.

Hello. My window is not quite 24.75 inches wide, but the inner space can accommodate the "wings" of a unit for almost another 1.5 inches,  Will that combination accommodate the LW1216ER / 12,000? Also, can I use a NO-DRILL bracket? Thanks.

Asked by: DOKENN
Hi DOKENN. The ENERGY STAR® LG 12000 BTU Window Air Conditioner, Model # LW1216ER has a width of 23 5/8" and is designed to be installed in standard single-hung or double-hung windows with actual opening widths from 27" to 39". The reason for the recommended opening widths is that you have to attach the left and right frame guide that have the curtains on them that you need to close any gaps between the air conditioner and your window frame after installation and for ease of installation. Your current width of 24 3/4" would only leave you with an opening of 9/16" on either side of the air conditioner to work with, probably less if your window is not quite 24 3/4". That is an extremely narrow opening and you will not be able to get your hands around the unit to install it, but you definitely will not be able to attach the left and right frame guides to use the curtains. The unit weighs 81 lbs and that will be another concern when attempting to install the unit if you are not able to get your hands around it to install it...^IFV
