Air Flow Options

This unit gives you two options for automating air flow. In Swing Mode, the unit will rotate through two air flow directions to ensure consistent comfort in every corner of your room.

Quiet Design

The unit can operate at volumes as low as 21 dB thanks to a combination of cutting edge components. LG utilizes a cross flow fan design that reduces noise levels by limiting the surface pressure of air flow.

Self-Cleaning Coil

The unit features a self-cleaning heat exchanger coil that automatically removes dirt and moisture. This helps to prevent unpleasant odors and to combat the formation of mold.

Automated Operation

Auto operation mode continually compares your zone's current and desired temperatures and uses that data to intelligently adjust the unit's fan speed and refrigerant flow to provide optimal comfort.

Dehumidify

LG's indoor units include a dehumidifying operation mode. In this mode, the unit's internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.

Improved Air Quality

The unit indoor unit uses a dual filtration system to keep your air clean. A washable anti-fungal filter is the first line of defense against dust and bacteria.

Hot-Start

When the Hot-Start function is enabled, the unit's fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.
