Low Returns
Fan-favorite reliability keeps return rates low across LG's broad appliance lineup.
LG's devotion to providing efficient ductless solutions can be seen across the Multi F line of indoor units. The KNMLB121A is a multi-position air handler unit that can be installed with nearly any pre-existing duct work. LG's air handlers are designed to provide powerful heating and cooling for the larger rooms in your home. Capable of managing high air speeds and volumes effortlessly, the unit is an impressive solution to your home's heating and cooling needs.
Enhanced Connectivity
LG's new R-32 mini split units require a 5-conductor cable (Not Included) instead of the standard 4-conductor, improving communication reliability and enabling a new leak detection feature.
Quiet Design
The unit can operate at volumes as low as 28 dB thanks to its advanced fan motor. The brushless direct current motor reduces electrical and mechanical sound while providing powerful air movement.
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.
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.
