  • Product Overview

    Few through-the-wall air conditioners are as easy to install and operate as the LG LT121CNR Wall Air Conditioner. A universal wall sleeve makes installation hassle free, and its loads of features ensure efficient operation. 11,500 BTUs of power make this LG ideal for cooling any indoor space as large as 550 square feet—particularly in rooms with no windows. Use its Cool mode to quickly cool down your space or simply turn on Fan-Only mode to circulate air on days when Cool mode isn’t needed.

    Digital controls, a programmable timer, automatic temperature control, and 3 operating modes are all included.

    Universal Wall Sleeve

    Installing or replacing the LG LT121CNR is nothing to fear, since it uses a standard-sized wall sleeve that fits multiple other AC brands, including models from Friedrich, GE, and Fedders/Emerson. Its sleeve dimensions are 25 3/8 inches by 16 23/32 inches, so it can hold most standard thru-wall ACs. This makes installation, maintenance, or even replacement much easier.

    Easily Control 3 Modes

    In addition to its Cool and Fan-Only modes, an eco-friendly Energy Saver mode conserves energy and saves you money. In this mode, the LG LT121CNR Through the Wall Air Conditioner turns its fan off once the compressor stops cooling and your room reaches your set temperature. Your room air is tested every 3 minutes, and the compressor turns back on when it's needed.

    A digital control panel and remote control make selecting a mode and setting your temperature a breeze.

    Additional Features

    • Gold Fin Anti-Corrosion: This outer coating keeps your LG AC running longer by protecting it from outdoor conditions.
    • Air Direction Control: 4-way air direction control is created by adjusting the louvers to the side or up and down to guide air where it's needed most.
    • Programmable Timer: Set your AC to turn on or off up to 24 hours in advance to ensure it only runs when you need it.
    • Ventilation Lever: Open the lever to let fresh air into your space, but make sure it's closed for effective cooling.  
    • 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 LT121CNR Wall 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 block airflow. Wash the air filter twice a month with luke warm water to keep your AC running efficiently.
    • Remote Control: Change settings from anywhere in the room with a digital remote control. 

    Summary

    With 11,500 BTUs of power, an Energy Saver mode, and endless features, this LG wall air conditioner makes cooling spaces up to 550 square feet a breeze.  

    What Customers Love

    • Universal Sleeve: Replacing an existing wall air conditioner or installing this one is made easier thanks to its universal wall sleeve.  
    • Savings: Features like a programmable timer, Energy Saving mode, and a washable air filter help you save money and energy.

    Things to Consider

    • Permanent Installation: Installing a thru-wall AC requires permanent installation, so consider a comparable window or portable air conditioner if you're not interested in adding this model to your home.
