OVERVIEW

Experience whole-home comfort with a clean, hidden installation using the LG 42,000 BTU 19.0 SEER2 LGRED 2 Zone Concealed Duct Mini Split Heat Pump System. Designed for homeowners and light commercial applications that prefer the appearance of traditional ducted HVAC without the expense of a central system, this ductless heat pump delivers efficient heating and cooling to two independently controlled zones while keeping indoor equipment completely out of sight.

Powered by LG's advanced inverter-driven heat pump technology, the system continuously adjusts compressor speed to match heating and cooling demand instead of repeatedly cycling on and off. This results in more consistent indoor temperatures, lower energy consumption, quieter operation, and enhanced overall comfort. The use of environmentally friendly R32 refrigerant further improves system efficiency while reducing environmental impact.

Key Features

  • 19.0 SEER2 Energy Efficiency: Delivers energy-efficient heating and cooling while helping reduce utility costs.
  • Hidden Concealed Duct Installation: Indoor units install above ceilings or inside soffits for a clean, unobtrusive appearance with discreet air distribution.
  • Independent Two-Zone Comfort: Allows separate temperature control in two different rooms for personalized comfort and improved efficiency.
  • LG Inverter Heat Pump Technology: Variable-speed inverter compressor maintains precise temperatures while reducing energy consumption.
  • R32 Refrigerant: Utilizes next-generation refrigerant for high-efficiency performance with a lower environmental impact.
  • Quiet Performance: Advanced inverter technology and concealed duct indoor units help minimize operating noise.
  • Flexible Ducted Air Distribution: Short duct runs provide even airflow through ceiling or wall registers while preserving room aesthetics.
  • Year-Round Heating & Cooling: Delivers reliable cooling in summer and efficient heat pump heating during colder months.
