FAQ

Q.
What is a suitable temperature setting for my air conditioner?
A.
When you turn on the air conditioner for the first time, set it to a low temperature and use a strong wind setting to quickly lower the temperature in the room. Once your room has cooled sufficiently, 25℃ is the optimal temperature to maintain a cool house and save energy.
The DUAL Inverter Compressor™ technology enables 40%1) faster cooling and saves up to 70%2) more energy than non-LG or non-inverter models.
1) Verified by TUV: LG inverter air conditioners(US-Q242K*) cools up to 40% more faster than LG non-inverter air conditioners(TS-H2465DAO). *Initial Temperature(Outdoor 35℃, Indoor 33℃), Setting Temperature(26℃).
2) Verified by TUV: LG inverter air conditioners(US-Q242K*) saves up to 70% more energy than LG non-inverter air conditioners(TS-H2465DAO). *Initial Temperature(Outdoor 35℃, Indoor 33℃), Setting Temperature(26℃), Testing Time (8 Hours).
Q.
What is the difference between an inverter air conditioner and a non-inverter air conditioner?
A.
Inverter air conditioners operate more efficiently than non-inverter air conditioners. Non-inverter air conditioners have compressors working at the same speed regardless of indoor temperature, turning off when the desired temperature is reached and turning on again when the temperature rises. Inverter air conditioners operate by adjusting the compressor speed faster at higher temperatures and slower at lower temperatures, which means they save more energy than non-inverter air conditioners and enable faster cooling and quieter operation.
Q.
How can I clean and manage the air conditioner?
A.
For clean wind and strong performance, the filter needs to be cleaned every two weeks. Wash the Pre-Filter with lukewarm water or use a neutral detergent for more stubborn dirt. After washing with water, dry the Pre-Filter in the shade away from direct sunlight. Clean an optional filter(Ultrafine dust filter, Fine Dust Filter, etc.) with a vacuum or a soft brush, but do not clean with water. You can use Auto Cleaning1) function for more convenient air conditioning management that automatically dries the AC interior when you turn it off2).
1) Initial Auto Cleaning setup requires the ThinQ app or remote control. Check the manual included with the product for details.
2) If you turn off the unit, the fan continues to run for 30 minutes.
The function is set to off when shipped from the factory.
The function may be change without notice, Please check the manual enclosed with the product for details.
Q.
How can I save energy while using the air conditioner?
A.
You can save energy by selecting appropriate temperatures when cooling and heating and by regularly cleaning the filters to reduce unnecessary energy wastage. It is recommended to set air conditioner to 25℃ for cooling and 21℃ for heating.
Q.
How do I install the air conditioner?
A.
Among the various types of air conditioners, a professional engineer must install Split type air conditioners because the installation process requires drilling through walls to connect outdoor and indoor units, and electrical wiring work.
