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 reduce electricity bill 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 kW Manager feature of LG air conditioners helps you use the desired amount of power. To use the kW 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.
