LG's devotion to providing efficient ductless solutions can be seen across their entire catalog. Part of the Four-Way Ceiling Cassette lineup of mini split indoor units, the KNSCB421A combines powerful multi-directional air flow with a low-profile design, allowing you to heat and cool large rooms discreetly. Thanks to the recessed installation design, a grille less than 1" thick is the only visible part of an installed KNSCB421A.

Product Information:

• 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.


• Air Flow Options: The KNSCB421A offers two automated air flow options: Swing Mode and Swirl Wind mode. Any of these modes can be activated to provide optimal circulation specific to your home.


• Quiet Design: The KNSCB421A can operate at volumes as low as 36 dB thanks to its advanced fan motor. The brushless direct current motor reduces electrical and mechanical sound while providing powerful air movement.


• Jet Cool: This LG unit feature a Jet Cool operation mode for rapid cooling. In this mode, the indoor unit will temporarily adjust the set point and fan speed for 30 minutes to quickly cool your zone.


• 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.


• Sleep Mode: With the sleep mode and timer functions, you can set this indoor unit to save energy at night. Sleep mode will incrementally adjust temperature for an hour before the timer function automatically deactivates the unit.


• Condensate Protection: Condensate overflow can damage your indoor unit and your home. An internal condensate pump with 31.5" of lift protects the KNSCB421A through reliable, effective condensate removal.


• 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 KNSCB421A features an anti-fungal filter to keep your air clean. This filter captures contaminants like dust and bacteria, and it is washable to ensure long term air quality.


• Hot-Start: When the hot-start function is enabled, the KNSCB421A'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.
