FAQ

Q. What is the difference between an inverter and a non-inverter air conditioner?
A. Non-inverter air conditioners run the compressor at a fixed speed, switching off when the desired temperature is reached and back on when it rises. Inverter air conditioners continuously adjust the compressor speed — faster when it’s hot, slower when it’s cool — for more consistent comfort and lower energy use.

*Verified by TÜV – LG inverter air conditioners cool up to 40% faster than LG non-inverter models. Initial Temperature: Outdoor 35°C, Indoor 33°C; Setting Temperature: 26°C. | *Plasmaster™ Ionizer+ removes 99% of adhering bacteria; verified by Intertek (model R24AWN, 8m³ test area). Odor reduction verified after 60 minutes. Efficiency may differ in actual conditions. | *Noise level based on LG internal test (Model V10API): less than 19 dBA. | *Comfort Sleep function must be activated. | *Energy consumption during A/C operation only.
