Mitsubishi PAA-CA36NL & SUZ-AK36NLHZ 36,000 BTU 17.2 SEER2 Cased Coil Hyper Heat Pump System - R454B

Mitsubishi PAA-CA36NL & SUZ-AK36NLHZ: 36,000 BTU Hyper-Heat Split System

The Mitsubishi PAA-CA36NL indoor cased coil paired with the SUZ-AK36NLHZ H2i® Hyper-Heating outdoor unit delivers powerful year-round comfort with exceptional cold-climate heating performance and energy-efficient cooling. Designed for residential and light commercial applications, this 36,000 BTU hybrid-ready split system combines Mitsubishi’s advanced inverter technology, intelligent furnace integration capabilities, and industry-leading hyper-heating performance for reliable operation in demanding environments.

The PAA-CA36NL indoor unit is engineered for compatibility with most ANSI-certified gas furnaces and supports Mitsubishi intelli-HEAT® technology, allowing intelligent switchover between heat pump and furnace operation based on outdoor conditions, energy efficiency goals, or comfort requirements. This hybrid functionality helps optimize heating performance while reducing energy consumption and carbon emissions during colder weather. The indoor unit features a durable, high-quality drain pan with excellent heat tolerance and low moisture absorption for long-term reliability. Flexible multi-position installation supports horizontal and vertical configurations—including left, right, upflow, and downflow orientations—making the system adaptable for both new construction and retrofit applications.

The SUZ-AK36NLHZ outdoor condenser features Mitsubishi’s renowned H2i® Hyper-Heating technology, providing 100% heating performance down to 5°F and guaranteed heating operation down to -13°F. An INVERTER-driven twin rotary compressor continuously adjusts output to match heating and cooling demand, delivering improved comfort, quieter operation, and enhanced energy efficiency. Flash Injection technology boosts compressor performance during extreme cold weather, while the built-in base pan heater helps prevent ice accumulation following defrost cycles for dependable winter operation.

Built for durability in harsh environments, the outdoor unit incorporates Blue Fin anti-corrosion coating and seacoast protection to defend against salt, sulfur, and airborne contaminants that can impact system longevity and efficiency. The system supports cooling operation in outdoor temperatures up to 115°F and heating operation down to -13°F, providing dependable comfort across a wide range of climates. Despite its powerful capacity, the system maintains quiet operation with outdoor sound levels as low as 52 dB(A) in cooling mode and 53 dB(A) in heating mode.

The system also supports a wide range of advanced controls and connectivity options, including the Mitsubishi Comfort app, kumo station®, BACnet® and Modbus® interfaces, wired and wireless controllers, remote temperature sensors, and third-party thermostat integration for flexible comfort management and building automation compatibility.
