FAQS

Q.
What is the difference between an inverter air conditioner and a non-inverter air conditioner?
A.
The difference between inverter air conditioners and non-inverter air conditioners is the control of the compressor operating speed. 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.
Q.
What is the ARTCOOL design?
A.
The LG ARTCOOL air conditioner is designed to blend seamlessly with your home's interior. The mirror glass on the front of the unit reflects the surrounding environment, enhancing the look of your space while delivering a timeless, premium aesthetic with its solid glass material.
Q.
How much energy can this air conditioner save?
A.
Both the S4-Q12JARTB (1.5HP) and S4-Q18KLRTE (2.0HP) feature LG's Dual Inverter Compressor, which delivers up to 70% energy savings compared to conventional air conditioners. The compressor continuously adjusts its speed to maintain your desired temperature without unnecessary energy use.
Q.
How much faster does the LG ARTCOOL cool a room?
A.
Thanks to the Dual Inverter Compressor and optimized airflow design, the LG ARTCOOL cools rooms up to 40% faster than conventional air conditioners. The Jet Cool function further enhances this by providing more powerful, direct airflow.
Q.
What does the Ionizer do?
A.
The built-in 4G Ionizer releases over 3 million ions that sterilize the air passing through the unit, as well as harmful substances and odours in the surrounding area. It has been proven to eliminate over 99% of adhering bacteria within 60 minutes, helping to maintain cleaner, fresher air in your space.
Q.
What is Active Energy Control?
A.
Active Energy Control allows you to manually select your preferred level of energy consumption based on your situation. This gives you the flexibility to balance comfort and energy efficiency depending on your needs at any given time.
Q.
What is the Comfort Sleep mode?
A.
Comfort Sleep mode creates the ideal sleeping environment by automatically adjusting three functions with a single click: indirect airflow, a 7-hour auto off timer, and soft wind sleep logic, so you stay comfortable throughout the night without manual adjustments.
Q.
What is Smart Diagnosis in LG Air Conditioners?
A.
Smart Diagnosis allows you to check setup details, installation status, troubleshooting steps, and other useful information directly from your smartphone, making it easier to identify and resolve issues without needing to call a technician for minor checks.
Q.
What warranty does the compressor carry?
A.
The LG Dual Inverter Compressor comes with a 10-year warranty, verified by TUV Rheinland through long-term accelerated reliability and high marginal testing. This ensures you enjoy the benefits of your LG air conditioner for a longer period.
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 filter with lukewarm water or use a neutral detergent for more stubborn dirt. After washing, dry the filter in the shade away from direct sunlight. You can also use the Auto Cleaning function for more convenient management. It automatically dries the AC interior when you turn it off, helping prevent the build-up of bacteria and mould on the heat exchanger. Note: Initial Auto Cleaning setup requires the remote control. Please check the manual for full 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 the air conditioner to 25°C for cooling. You can also use the Active Energy Control feature to limit energy consumption based on your situation.
Q.
Does this air conditioner support dehumidification?
A.
Yes, both the S4-Q12JARTB and S4-Q18KLRTE support dehumidification mode, helping to reduce excess humidity in your space for a more comfortable environment.
Q.
How do I install the air conditioner?
A.
There are two main types of air conditioners: Split air conditioners and duct-free air conditioners. Split air conditioners require professional installation, and duct-free air conditioners (Window ACs, Wall-type ACs, Portable ACs, etc.) don't require duct installation because they have built-in outdoor units. A professional engineer must install split-type air conditioners because the installation process requires drilling through walls to connect the outdoor and indoor units and involves electrical wiring.
