FAQ
-
What is a suitable temperature setting for my air conditioner?
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 Smart Inverter Compressor™ technology enables 40%1) faster cooling and saves up to 70%2) more energy than non-inverter models.
1)Verified by TÜV: 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 TÜV: 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).

What is the difference between an inverter air conditioner and a non-inverter air conditioner?
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.
-
How can I clean and manage the air conditioner?
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, Allergy filter etc.) with a vacuum or a soft brush, but do not clean with water. You can use Auto Clean+1) function for more convenient air conditioning management that automatically dries the AC interior when you turn it off2).
1)Initial Auto Clean+ setup requires the ThinQ app or remote control. Check the manual included with the product for details.
2)When the product is turned off, it automatically sets an appropriate drying time based on the operating conditions. The drying time can be up to 30 minutes and may vary depending on the product. 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.
-
How can I reduce energy consumption while using the air conditioner?
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. Additionally, using the Smart Energy Manager feature of LG air conditioners helps you use the desired amount of power. To use the Smart Energy Manager feature, a connection to ThinQ is required, and it is only available on models that support this feature. Please refer to the manual included with the product for more details.
-
How do I install the air conditioner?
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.
-
Can LG air conditioners provide heating as well as cooling?
LG air conditioners have both cooling and heating functions, so they can be used all year round. LG air conditioners use heat pump technology to provide efficient heating.
-
How quiet is the air conditioner?
Thanks to LG's DUAL Inverter Compressor™ technology, inverter air conditioners are generally quiet. Models equipped with LG's DUAL Inverter Compressor™ technology optimize operating noise to maintain a quiet environment. Noise levels can vary depending on each model, so it is advisable to check the noise specifications of each model before purchasing. In general, inverter air conditioners operate more quietly than non-inverter air conditioners.

What are the benefits of a dual vane?
Providing you with ideal comfort in any season, the dual vanes disperse airflow both upward and downward, reaching farther and faster. With biomimetic technology, the 6-level angle-adjustable dual vanes offer tailored airflow control at your fingertips.
Strong airflow can be directed from both the front and bottom vanes. The dual vanes can send cool air upward for up to 23% faster cooling without a drafty sensation and direct warm air downward for up to 6% faster heating, avoiding direct hot air.
