Designed for residential and light commercial applications, this 42,000 BTU hybrid-ready split system combines Mitsubishi’s advanced inverter technology, H2i® Hyper-Heating performance, and intelligent furnace compatibility to provide reliable comfort even in extreme winter conditions.\u003c\/p\u003e\n\u003cp\u003eThe PAA-BA42NL 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. This hybrid functionality helps optimize comfort, improve energy efficiency, and reduce energy costs by automatically selecting the most effective heating source based on outdoor conditions. 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 to a wide range of HVAC applications and retrofit projects.\u003c\/p\u003e\n\u003cp\u003eThe PUZ-AK42NLHZ 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, improving comfort while reducing energy consumption and temperature fluctuations. Flash Injection technology enhances compressor performance during extreme cold weather, while the built-in base pan heater helps prevent freeze-up after defrost cycles for dependable winter operation.\u003c\/p\u003e\n\u003cp\u003eBuilt for durability in harsh environments, the outdoor unit incorporates Blue Fin anti-corrosion coating and Seacoast Protection to guard against salt, sulfur, and airborne contaminants that can impact system performance and longevity. The system supports cooling operation from 23°F to 115°F and can operate down to 0°F in cooling mode when equipped with optional wind baffles. Despite its powerful performance, the system maintains quiet operation with outdoor sound levels of just 60 dB(A) in cooling mode and 62 dB(A) in heating mode.\u003c\/p\u003e\n\u003cp\u003eThe system also supports advanced smart controls and connectivity options, including Mitsubishi’s 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGeneral Information\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSystem Type: Cased coil indoor unit + single-zone Hyper-Heat heat pump outdoor unit\u003c\/p\u003e\n\u003cp\u003eModels: Indoor – PAA-BA42NL | Outdoor – PUZ-AK42NLHZ\u003c\/p\u003e\n\u003cp\u003eCapacities: 42,000 BTU Rated Cooling (Max 44,500 | Min 17,300)\u003c\/p\u003e\n\u003cp\u003eHeating Capacity: 54,000 BTU at 47°F | 38,500 BTU at 17°F | 48,000 BTU Maximum at 5°F\u003c\/p\u003e\n\u003cp\u003eRoom Size: Ideal for residential and light commercial spaces up to ~2,000–2,500 sq ft\u003c\/p\u003e\n\u003cp\u003eOperating Modes: Heating \u0026amp; Cooling\u003c\/p\u003e\n\u003cp\u003eENERGY STAR®: No\u003c\/p\u003e\n\u003cp\u003eRefrigerant \/ Factory Charge: R-454B, 11 lb 7 oz (pre-charged for 100 ft line length)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eH2i® Hyper-Heating: 100% heating performance down to 5°F with guaranteed heating operation to -13°F\u003c\/p\u003e\n\u003cp\u003eINVERTER-Driven Twin Rotary Compressor: Precise heating and cooling capacity control\u003c\/p\u003e\n\u003cp\u003eintelli-HEAT® Compatibility: Intelligent hybrid furnace integration capability\u003c\/p\u003e\n\u003cp\u003eFlash Injection Technology: Enhanced compressor performance during extreme cold weather\u003c\/p\u003e\n\u003cp\u003eBuilt-In Base Pan Heater: Prevents ice buildup after defrost cycles\u003c\/p\u003e\n\u003cp\u003eHigh Airflow Output: Up to 1,660 CFM for efficient air distribution\u003c\/p\u003e\n\u003cp\u003eBlue Fin \u0026amp; Seacoast Protection: Corrosion-resistant outdoor coil protection\u003c\/p\u003e\n\u003cp\u003eQuiet Operation: Outdoor sound levels as low as 60 dB(A) cooling and 62 dB(A) heating\u003c\/p\u003e\n\u003cp\u003eFlexible Installation: Multi-position indoor installation configurations\u003c\/p\u003e\n\u003cp\u003eSmart Controls: Comfort app compatibility, wired\/wireless remotes, BACnet®, Modbus®, and thermostat interfaces\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications (Rated Conditions)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCooling Capacity: 42,000 BTU (Max 44,500 | Min 17,300) | SEER2: 17.1 | EER2: 10.8\u003c\/p\u003e\n\u003cp\u003eHeating Capacity: 54,000 BTU at 47°F | 38,500 BTU at 17°F | HSPF2: 8.7\u003c\/p\u003e\n\u003cp\u003eCOP: 2.7 at 47°F | 1.70 at 17°F | 1.75 at 5°F | 1.58 at -13°F\u003c\/p\u003e\n\u003cp\u003eElectrical: 208\/230 V, 1-Ph, 60 Hz | Outdoor MCA: 35 A | MOCP: 60 A\u003c\/p\u003e\n\u003cp\u003eIndoor Airflow: 936–1,660 CFM\u003c\/p\u003e\n\u003cp\u003eOutdoor Sound: 60 dB(A) Cooling | 62 dB(A) Heating\u003c\/p\u003e\n\u003cp\u003ePiping: Liquid 3\/8 in | Gas 5\/8 in | Max line length: 100 ft | Max height: 100 ft\u003c\/p\u003e\n\u003cp\u003eOutdoor Operating Range: Cooling 23°F to 115°F | Heating down to -13°F\u003c\/p\u003e\n\u003cp\u003eHeating Thermal Lock-Out \/ Restart: -22°F \/ -13°F\u003c\/p\u003e\n\u003cp\u003eOutdoor Dimensions \/ Weight: 41-11\/32 × 14 × 52-43\/64 in | 271 lb\u003c\/p\u003e\n\u003cp\u003eIndoor Dimensions \/ Weight: 17-1\/2 × 21-3\/8 × 32 in | 72.8 lb (cased coil)\u003c\/p\u003e\n\u003cp\u003eDrain Connection: 3\/4 in O.D.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncluded Components\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIndoor Unit: PAA-BA42NL cased coil indoor unit\u003c\/p\u003e\n\u003cp\u003eOutdoor Unit: PUZ-AK42NLHZ Hyper-Heat heat pump condenser\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHomes and light commercial spaces requiring dependable year-round heating and cooling in colder climates.
