OVERVIEW

Experience the comfort of a traditional ducted HVAC system with the efficiency and flexibility of ductless technology with the LG 42,000 BTU 19.0 SEER2 LGRED° 5 Zone Concealed Duct Mini Split Heat Pump System. Designed for larger homes and light commercial applications, this premium multi-zone system provides individualized heating and cooling for up to five separate areas while keeping the indoor equipment completely hidden from view. Combining LG's industry-leading LGRED (Low Ambient Heating) technology, concealed duct air handlers, and environmentally friendly R32 refrigerant, this system delivers reliable year-round comfort with a clean, unobtrusive installation.

Unlike traditional wall-mounted mini split systems, concealed duct indoor units are installed above ceilings or inside soffits and connected to short duct runs that deliver conditioned air through discreet ceiling or wall registers. This hidden design preserves your interior décor while providing the appearance of a conventional central HVAC system, making it an excellent choice for homeowners seeking both performance and aesthetics.

Key Features

  • 19.0 SEER2 Energy Efficiency: Delivers outstanding efficiency while helping reduce monthly heating and cooling costs with advanced LG inverter technology.
  • Independent Five-Zone Comfort: Five individually controlled ceiling cassette indoor units allow each room to maintain its own temperature setting, improving comfort while reducing unnecessary energy consumption.
  • Concealed Duct Installation: Hidden concealed duct air handlers install above ceilings or within soffits and distribute conditioned air through short duct runs and discreet supply grilles for a clean, finished appearance.
  • LGRED Cold Climate Heating: LGRED technology is engineered to provide dependable heating performance in low outdoor temperatures, making it an excellent choice for regions with colder winter climates.
  • Environmentally Friendly R32 Refrigerant:The system utilizes advanced R32 refrigerant, providing high-performance heating and cooling while reducing environmental impact compared to older refrigerants.
