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% 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*) save 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 optional filters (Ultrafine dust filter, Fine Dust Filter, etc.) with a vacuum or a soft brush, not with water. You can use Auto Cleaning1) for more convenient air conditioning management that automatically dries the air conditioner interior when you turn it off.2)

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 changed 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 by regularly cleaning the filters to reduce unnecessary energy wastage. It is recommended to set air conditioners to 25℃ for cooling.
Q.
How do I install the air conditioner?
A.
Among the various types of air conditioners, split type air conditioners must be installed by a professional engineer because the installation process requires drilling through walls to connect outdoor and indoor units and electrical wiring work.
Q.
What is the function of Gen Mode+™?
A.
Gen Mode+™ is a feature that allows you to limit the power consumption value of the air conditioner in three stages so that you can adjust the power consumption value more flexibly according to your usage environment. By limiting the maximum power consumption of the air conditioner, this feature ensures that the generator capacity is not exceeded and the power is not cut off when using the air conditioner with other appliances. Gen Mode+™ is only available in cooling mode, and other operating modes (AI, heating, dehumidification, fan, power cooling, etc.) disable the Gen Mode+™ function.
Q.
Does using Gen Mode+™ affect the cooling function?
A.
When using the Gen Mode+™ feature, the cooling capacity may vary depending on the amount of heat that needs to be removed, but you can reduce your electricity bill by limiting the power usage of the air conditioner.
Q.
Is the function of Gen Mode+™ set automatically?
A.
You can choose the power consumption level or value by pressing a button on the remote control. This is useful when you switch between the power from the station and the power from your own generator. You can manually choose among the 3 pre-set power levels, but the levels will not be set automatically.
Q.
What is the function of Mosquito Away?
A.
This feature makes ultrasonic waves that confuse mosquitoes. Mosquitoes use human odor and CO2 to find people to bite, but this device makes it harder for them to do so. It works best within 5–7 meters from the air conditioner, depending on the room. While it doesn’t kill mosquitoes, it can lower the chance of getting bitten by 60-80%.
Q.
Is the Mosquito Away function harmful to the human body?
A.
The noise-free ultrasonic waves generated by LG air conditioners are safe and well within the IRPA Exposure Limit for humans.
Q.
Can the Mosquito Away function be used on its own
A.
You can use the Mosquito Away feature with or without cooling. If you use it without cooling, the outdoor part of the air conditioner (the dual inverter compressor) will not operate, only the indoor fan and module.
