Capacity & Efficiency: 36,000 BTU capacity provides robust heating/cooling, with inverter technology reducing energy consumption by avoiding constant on/off cycles.
Design & Installation: These are "hidden" or "concealed" units typically installed above ceilings or in closets, providing a discreet alternative to wall-mounted split units.
Multi-Zone Capability: The Multi21+ system allows for multiple indoor units (such as 9k+9k+9k+9k or other combinations) to be connected to a single outdoor unit.
Performance: Features R-410A refrigerant, variable speed DC inverter compressors, and often includes an internal condensate pump.
Application: Ideal for residential zoning, large offices, or commercial areas up to roughly 1500-1800 sq. ft. depending on insulation.
