What People Are Saying

Rated 5 out of 5 by from Quite with a lot of great features We bought it for the air conditioner to begin with then a few nights later needed it for the heat. Worked beautifully. Love it!!

Rated 3 out of 5 by from I bought 2 units. Had to have a 220 volt outlet installed. Hooked up the first one and it cooled great. However the heat did not work. Replaced it with the second unit and both features work fine. I'm now working to get warranty service on the first unit and hopefully it will be resolved soon.

Rated 5 out of 5 by from Very efficient; great investment! This 12,000 BTU air conditioner/heater is just perfect for year-round comfort! I especially appreciate the Energy Saver. The thermostat allows me set a desired temperature -- and walk away! My unit accommodates a three-car garage and work shop. And still, it runs very little, once the atmosphere is reached. Excellent quality and attractive product. The remote is the cherry on top! Easy to use.

Rated 5 out of 5 by from Does the job. We have an unusual home consisting of several buildings, each with its own HVAC. This unit is in our den and cools it nicely in Econ mode. We will have to wait for cooler weather to see about the heat but are confident it will do well. Thanks.

Rated 4 out of 5 by from Great for the price I bought this to replace my 800 btu AC that I had in my bedroom. I went with the higher btu thinking that it would make my bedroom very cold. I like sleeping in the cold. It didn't make it any cooler then the smaller unit. It does work well. I like how a red light comes on the alert you when it's time to clean the air filter.

I would like to install this unit through a concrete block wall. Why don't you recommend doing this?

Asked by: Cleos
The LG 12000 BTU Window Air Conditioner, Cooling & Heating, Model # LW1216HR is requires a standard single-hung or double-hung window for proper installation. It is designed for installation in standard double hung windows with actual opening widths from 27" to 39". The top and bottom window sash must open sufficiently to allow a clear vertical opening of 16" from the bottom of the upper sash to the window stool. The outside of the cabinet must extend outward for at least 12" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner which is why all side louvers of the cabinet must remain exposed to the outside of the structure. Installing this unit through a concrete block wall would require using a wall sleeve for support which would cover the side louvers as would a hole in the wall. That would restrict outside air as described above which would reduce the unit's cooling efficiency or cause the unit to overheat and burn itself out. Installing the unit in a manner other than outlined in the owners manual would also void your warranty...^IFV
