Designed for compatibility with gas furnace systems and hybrid HVAC installations, this 42,000 BTU split-system air conditioner combines Mitsubishi’s advanced inverter-driven technology, flexible installation options, and durable construction to provide reliable comfort and exceptional cooling performance throughout the season.\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 integration within hybrid HVAC systems. While paired with a cooling-only outdoor condenser, the indoor unit is designed to support future system flexibility and advanced comfort solutions. A high-quality drain pan with excellent heat tolerance and low moisture absorption helps ensure long-term reliability and dependable operation. Flexible multi-position installation supports horizontal left, horizontal right, upflow, and downflow configurations, making the unit ideal for both retrofit projects and new construction applications.\u003c\/p\u003e\n\u003cp\u003eThe PUY-AK42NL outdoor condenser utilizes Mitsubishi’s INVERTER-driven twin rotary compressor technology to precisely match cooling demand. Unlike traditional single-stage air conditioners, inverter technology continuously adjusts compressor speed to maintain more consistent indoor temperatures, improve efficiency, reduce energy consumption, and minimize temperature swings. With a rated cooling capacity of 42,000 BTU and a maximum capacity of 43,000 BTU, the system delivers powerful cooling performance for larger residential and light commercial spaces.\u003c\/p\u003e\n\u003cp\u003eBuilt for long-term durability, the outdoor unit incorporates Blue Fin anti-corrosion coating and Seacoast Protection to help protect the heat exchanger from salt, sulfur, and airborne contaminants. These features make the system particularly well suited for coastal environments and other demanding outdoor conditions. The condenser supports cooling operation in outdoor temperatures from 23°F up to 115°F, ensuring dependable performance across a wide range of climates and applications.\u003c\/p\u003e\n\u003cp\u003eDespite its robust cooling capacity, the system maintains quiet operation with outdoor sound levels as low as 52 dB(A). Advanced control options support Mitsubishi Comfort app connectivity, kumo station®, BACnet® and Modbus® interfaces, wired and wireless remote 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 cooling-only outdoor condenser\u003c\/p\u003e\n\u003cp\u003eModels: Indoor – PAA-BA42NL | Outdoor – PUY-AK42NL\u003c\/p\u003e\n\u003cp\u003eCapacities: 42,000 BTU Rated Cooling (Max 43,000 | Min 15,400)\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: Cooling Only\u003c\/p\u003e\n\u003cp\u003eENERGY STAR®: No\u003c\/p\u003e\n\u003cp\u003eRefrigerant \/ Factory Charge: R-454B, 9 lb 14 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\u003eINVERTER-Driven Compressor: Precise cooling output for improved comfort and efficiency\u003c\/p\u003e\n\u003cp\u003eTwin Rotary Compressor: Smooth, reliable, and energy-efficient operation\u003c\/p\u003e\n\u003cp\u003eintelli-HEAT® Compatible Indoor Unit: Supports hybrid HVAC applications with compatible equipment\u003c\/p\u003e\n\u003cp\u003eHigh Airflow Performance: Up to 1,660 CFM indoor airflow\u003c\/p\u003e\n\u003cp\u003eBlue Fin Coating: Corrosion-resistant outdoor heat exchanger protection\u003c\/p\u003e\n\u003cp\u003eSeacoast Protection: Enhanced durability in coastal and harsh environments\u003c\/p\u003e\n\u003cp\u003eQuiet Operation: Outdoor sound levels as low as 52 dB(A)\u003c\/p\u003e\n\u003cp\u003eFlexible Installation: Multi-position indoor installation configurations\u003c\/p\u003e\n\u003cp\u003eCooling Operation Range: Outdoor temperatures from 23°F to 115°F\u003c\/p\u003e\n\u003cp\u003eSmart Controls: Comfort app compatibility, wired\/wireless remotes, thermostat and building automation 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 43,000 | Min 15,400) | SEER2: 17.1 | EER2: 10.3\u003c\/p\u003e\n\u003cp\u003eElectrical: 208\/230 V, 1-Ph, 60 Hz | Outdoor MCA: 34 A | MOCP: 56 A\u003c\/p\u003e\n\u003cp\u003eIndoor Airflow: 936–1,660 CFM\u003c\/p\u003e\n\u003cp\u003eOutdoor Sound: 52 dB(A) Cooling\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: 23°F to 115°F Cooling Ambient\u003c\/p\u003e\n\u003cp\u003eOutdoor Dimensions \/ Weight: 41-11\/32 × 14 × 52-43\/64 in | 224 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: PUY-AK42NL inverter-driven air conditioning condenser\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHomes and light commercial spaces seeking high-capacity, energy-efficient cooling with advanced inverter technology and flexible furnace compatibility.
