Mitsubishi PAA-BA30NL & PUY-AH30NL 30,000 BTU 16.1 SEER2 Cased Coil Cooling Only System - R454B

Mitsubishi PAA-BA30NL & PUY-AH30NL: 31,000 BTU Cooling-Only Split System

The Mitsubishi PAA-BA30NL indoor cased coil paired with the PUY-AH30NL outdoor condenser delivers powerful, efficient cooling performance for residential and light commercial applications. Designed for compatibility with gas furnaces and Mitsubishi intelli-HEAT® systems, this 31,000 BTU cooling-only split system offers reliable operation, flexible installation options, and advanced inverter-driven technology for year-round comfort in homes, offices, retail spaces, and retrofit HVAC projects.

The PAA-BA30NL indoor unit is engineered for compatibility with most ANSI-certified gas furnaces and supports Mitsubishi’s Intelligent Switchover technology for hybrid HVAC applications. The system can automatically transition between heat pump and furnace operation based on outdoor conditions, energy efficiency goals, or carbon reduction preferences. The indoor unit features a durable, high-quality drain pan with excellent heat resistance and low moisture absorption for long-term reliability. Flexible multi-position installation supports horizontal left or right configurations as well as vertical upflow and downflow applications, making it suitable for a wide variety of installation environments. With airflow up to 1,024 CFM, the indoor coil delivers strong, consistent air distribution throughout the conditioned space.

The PUY-AH30NL outdoor condenser utilizes Mitsubishi’s INVERTER-driven twin rotary compressor technology to provide precise cooling output while minimizing energy consumption. Blue Fin anti-corrosion coating and Seacoast Protection help safeguard the outdoor heat exchanger from salt, sulfur, and airborne contaminants, improving durability and maintaining performance in challenging environments. The system delivers dependable cooling operation in outdoor temperatures up to 115°F while maintaining quiet operation with outdoor sound levels as low as 49 dB(A).

Advanced control compatibility provides flexible comfort management options, including Mitsubishi’s Comfort app, kumo cloud®, wired and wireless remote controllers, thermostat interfaces, BACnet® and Modbus® integration, and remote temperature sensing accessories. Combined with inverter technology and robust construction, the PAA-BA30NL & PUY-AH30NL system delivers reliable, energy-conscious cooling performance for demanding applications.
