OVERVIEW

Bring premium comfort, energy efficiency, and individualized climate control to larger homes and light commercial spaces with the LG 54,000 BTU 20.6 SEER2 5 Zone Ceiling Cassette Mini Split Heat Pump System. Designed to heat and cool up to five independently controlled zones, this advanced ductless system combines LG's Multi F inverter technology with sleek 4-way ceiling cassette indoor units to deliver reliable year-round comfort while maintaining a clean, modern appearance.

Designed for maximum flexibility, each ceiling cassette air handler operates independently, allowing occupants to customize temperatures in individual rooms. Whether you're conditioning bedrooms, living rooms, kitchens, offices, conference rooms, or additions, each zone receives personalized comfort while helping reduce energy consumption by conditioning only occupied spaces.

The low-profile 4-way ceiling cassette units install flush within suspended or finished ceilings, preserving valuable wall space and blending seamlessly into virtually any décor. Their four-way airflow pattern distributes conditioned air evenly throughout each room, minimizing hot and cold spots while maintaining balanced temperatures and enhanced occupant comfort.

Key Features

  • 20.6 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.
  • 4-Way Ceiling Cassette Design: Low-profile ceiling cassette units install flush within the ceiling and distribute conditioned air in four directions for balanced airflow and consistent room temperatures.
  • LG Inverter Heat Pump Technology: Variable-speed inverter technology continuously adjusts compressor speed to match demand, delivering precise temperature control, quieter operation, and enhanced energy efficiency.
  • Environmentally Friendly R32 Refrigerant: The system utilizes advanced R32 refrigerant, providing high-performance heating and cooling while reducing environmental impact compared to older refrigerants.
