LG Multi-Position Air Handler – Flexible, Efficient Ducted Comfort Solution

Product Profile

The LG Multi-Position Air Handler is designed for flexibility and performance in residential and light commercial applications. Its convertible configuration, supporting vertical upflow, downflow, or horizontal airflow, allows contractors to install the unit in the orientation that best suits each project. This 4-way configurable design enables homeowners using traditional ducted systems to experience the benefits of LG’s inverter technology, combining efficiency with installation versatility.

Key Features and Benefits

  • Flexible Installation Options: The air handler supports multiple airflow configurations, including horizontal left, horizontal right, vertical upflow, and vertical downflow. Downflow installation requires the optional accessory kit (PNDFA0). This adaptability makes it suitable for various layouts and ducted applications.
  • High External Static Pressure Capability: With ESP up to 1.0 in. wg, the unit accommodates flexible ductwork designs, supporting longer runs or complex layouts while maintaining efficient airflow.
  • Built-In Refrigerant Leak Detection: A factory-installed leak detection sensor helps mitigate refrigerant release, contributing to safer and more reliable system operation.
  • Energy Efficiency: Most models are ENERGY STAR® certified, which may allow customers to qualify for rebates or incentives, depending on local programs.
  • Wide Operating Range: The system operates effectively across a broad temperature spectrum—heating down to -13 °F (for LGRED° models) and cooling up to 118 °F—providing comfort in both hot and cold climates.
  • Reliable Heating Performance: LGRED° models deliver 100% of rated heating capacity at 5 °F, ensuring strong performance even in extreme winter conditions.
  • Smart Connectivity: The unit’s Wi-Fi capability enables convenient control through the LG SmartThinQ® app, offering easy access to system settings and comfort management from compatible devices.
