  • Energy Savings up to 35% with LG DUAL Inverter ENERGY STAR D Dual Inverter COMPRESSOR LG Inverter Technology is a key attribute of LG's new room air conditioners. It is used in conjunction with a variable-speed compressor and adjusts the compressor motor speed to regulate temperature. This is more energy efficient than non-inverter technology room air conditioners, which turn the compressor either on or off to regulate temperature. In the Department of Energy approved testing, LG's Inverter room air conditioner model (LW1222IVSM) showed a 35% Combined Energy Efficiency Ratio (CEER) positive difference when compared with the ENERGY STAR* minimum CEER requirement.
  • How to Choose the Right Air Conditioner for Your Room: 1. Measure Your Room: Calculate the room size by multiplying the length and width in square feet. 2. Match Room Size to BTUs: Determine the appropriate BTU capacity for your room based on its size. 3. Verify Size of Window Opening: Ensure that the window opening is at least 16 inches wide and 27 inches high. 4. Check Electrical Requirements: Make sure your circuit is adequate for the air conditioner's amperage rating. For the Perfect Fit, Be Sure to Check These Requirements: 1. Verify Size of Window Opening: Ensure that the window opening is at least 16 inches wide and 27 inches high. 2. Check Electrical Requirements: Determine if your circuit is adequate for the air conditioner's amperage rating. 3. Window Size: The window should be at least 16 inches wide and 27 inches high. 4. 115 Volts AC: The air conditioner should be compatible with 115 volts AC. 5. 15 Amps Draws: The air conditioner should have a draw of 15 amps or less. 6. 72" Grounded Cord: The air conditioner should come with a 72-inch grounded cord.

    After the Best Buy installers finally showed up and then left without installing my AC, my schedule has not worked out to be able to be present when my current installer is available. It is still in the box - After all the hassle, I certainly hope it works well. So far, this has not been a good experience.

  • Not worth the hassle. Error code in a years time

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Purchase date January 31, 2024. As of March 29, 2025 my unit is not working. Error code CH21 is showing on the panel. I've contacted LG as well as Geek Squad. LG says 1 year warranty and Best Buy would like for me to bring the unit in store. I thought someone would come out and see about the unit. I now have to take this unit out of my window to have it fixed. I then have to rent a truck. To say I'm disappointed is an understatement.

      Hello there, LakeshaB. Thank you for sharing your experience with us. We understand that your LW1222IVSM window air conditioner is displaying the CH21 error code, and we recognize the inconvenience this situation has caused. Your feedback is important, and we'd like to assist you further.

      The CH21 error code typically indicates a technical issue within the unit's inverter DC power circuit. While some users have attempted troubleshooting steps such as turning off the AC, unplugging it from the power outlet, and cleaning the indoor fan coil unit, we recommend seeking professional service to ensure safety and proper handling.​
