Efficient, Energy Saving Inverter Technology

LG Window Air Conditioners with DUAL Inverter Compressor™ are up to 35% more energy savings* than the ENERGY STAR® certification requirement. Enjoy LG's innovative Inverter Technology that's both powerful and quiet.
*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 turns the compressor either on or off to regulate temperature. In 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 DOE Minimum Requirement of 10.9 CEER.
*The estimated annual energy cost is based on a national average electricity cost of 13 cents per kWh and seasonal use of 8 hours a day over a 3-month period. Your exact costs will depend on local utility rates and the type and source of your energy.
*When in sleep mode.

What people are saying

Rated 3 out of 5 by from Frustrated with my AC. It is a lemon!! I bought two AC’s about 3-4 Months ago. One AC has been a problem. Code CH 05 shows and the AC only works intermittently. It has been a couple months that I have had to deal with this. A brand new AC that doesn’t work. Now I am waiting for the back up technician to receive a part and install it. If it still does not work properly LG should give me another AC with no charge!!

Rated 5 out of 5 by from Very quiet and well built I bought this unit to replace a 5 year old Friedrich CP series unit that had a fan failure that was too expensive to repair. This LG model is much better built (in my opinion ) and much quieter.
