  • Product Overview

    Cooling power, versatility, and efficient features all blend together in the Energy Star-rated LG LW1212ER Window Air Conditioner. Perfect for cooling areas around 550 square feet, the LG LW1212ER features an Energy Saving mode to reduce energy costs. Digital controls make setting your ideal temperature simple, while a remote control lets you easily choose 1 of 4 operating modes.

    In addition, this 12000 BTU air conditioner offers a programmable timer, automatic restart, and 4-way air direction.   

    Multiple Modes and Speeds

    Many window air conditioners offer additional modes to keep you comfortable all year, but this model has one that will save you money and reduce your carbon footprint. Its 4 modes include:  

    • Cool: Up to 12,000 BTUs are used to quickly cool your living room, bedroom or other space.
    • Fan: When Cool mode isn’t needed, just turn on the fan to circulate air and avoid stuffiness.
    • Dry: Remove excess moisture from your room with Dry mode.
    • Energy Saver: In this money- and energy-saving mode, the fan stops when the compressor finishes cooling. If needed, the fan will kick on to maintain the set temperature but won't run continuously like in Cool mode.

    With 3 cooling and fan speeds, you control how quickly your room cools down. You can also rely on its Auto cool setting, which determines its speed based on your ambient room temperature.

    Energy Star-Rated

    The estimated yearly cost to run the LG LW1212ER is only $89—far less than many other window ACs. This is because of the already-mentioned Energy Saver mode and its Energy Efficiency Ratio (EER) of 10.8. These features helped the LG LW1212ER Air Conditioner become Energy Star-rated. Energy Star-rated models are at least 10% more efficient than other models its size. You know you're making an investment with one of these ACs, and it will save you energy and money.

    A programmable timer can also help you save money by ensuring your AC only runs when you need it—and that it's turned off when you don't. The timer programs your AC to turn on or off up to 24 hours in advance. In addition to being convenient, this can save you money and reduce energy usage. For example, if you want your space to be cool at a certain time (like when you get home from work), program it to turn on at that time instead of running it all day.

    Additional Features

    • Air Direction Control: 4-way air direction control is created because by adjusting the louvers to the side or up and down to guide air where it's needed most.
    • Automatic Restart:  Summer brings heavy storms, high winds, and extreme heat—all of which can cause power outages. This feature automatically turns your AC back on to the previous settings once power is restored.
    • Digital Controls: Convenient and easy-to-use, the LG 12000 Window Air Conditioner offers a digital control board to make changes and adjust settings. 
    • Washable Air Filter: This air filter traps particles that can build up and blow airflow. Wash the air filter twice a month under the sink to keep your AC running efficiently.
    • Remote Control: Change settings from anywhere in the room with a digital remote control. 


    4 modes, 3 cooling and fan speeds, and a programmable timer, the LG LW1212ER Window Air Conditioner gives you complete control of the temperature in your space.  

    What Customers Love

    • Gives You Control: With 4 modes, 3 fan and cooling speeds, and a 24-hour programmable timer, you truly have total control over how your room is cooled.
    • Savings: Not only is this model priced to sell, features like a programmable timer, Energy Saving mode, and a washable air filter help you save continuously.
    • 115-volts: This model is fairly powerful yet plugs into a standard 110-120-volt plug.

      Comments about LG 12,000 BTU Window Air Conditioner - LW1212ER:

      I bought two units for the kitchen, dining room and living room areas of my 170 year old Victorian. I had a handy man put them in since they weighted 90 pounds. They Cooled quickly, quietly and with fans to circulate between the three large areas, I found them to be a perfect solution. I felt pretty secure about the quality and performance because of the Consumer Reports rating.

      Comments about LG 12,000 BTU Window Air Conditioner - LW1212ER:

      AC arrived with a few loose screws that seemed to happen during shipping. These were essential screws that hold down the compressor and fan blades. Had to tighten myself before installation and had to use best guess on torque requirements.
      Unit arrived with broken styrofoam and partially opened packaging from UPS. This may have caused screws to come loose but not 100% sure.
