Mitsubishi PAA-AA30NL & PUY-AH30NL: 31,000 BTU Cooling-Only Split System

The Mitsubishi PAA-AA30NL indoor cased coil paired with the PUY-AH30NL outdoor condenser delivers efficient, reliable cooling performance for residential and light commercial applications. Designed for use with compatible gas furnaces and Mitsubishi intelli-HEAT® systems, this 31,000 BTU cooling-only setup provides consistent airflow, quiet operation, and flexible installation for homes, offices, retail spaces, and retrofit HVAC projects.

The PAA-AA30NL indoor unit is engineered for compatibility with most ANSI-certified gas furnaces, supporting Mitsubishi’s intelligent switchover technology for hybrid HVAC applications. The unit features a durable, high-quality drain pan with low moisture absorption and excellent heat resistance for long-term reliability. Flexible multi-position installation allows horizontal or vertical mounting configurations—including left, right, upflow, and downflow orientations—making the system adaptable to a wide range of layouts. With airflow up to 1,024 CFM, the indoor coil delivers even air distribution and dependable comfort throughout the conditioned space.

The PUY-AH30NL outdoor condenser utilizes Mitsubishi’s INVERTER-driven twin rotary compressor technology to provide efficient, precise cooling control while reducing energy consumption. Designed for durability in harsh climates, the outdoor unit includes Blue Fin anti-corrosion coating and seacoast protection to help resist salt, sulfur, and airborne contaminants. The system delivers dependable cooling performance in outdoor ambient temperatures up to 115°F while maintaining quiet operation with outdoor sound levels as low as 49 dB(A).

This system supports a wide range of smart control and connectivity options, including compatibility with Mitsubishi’s Comfort app, kumo cloud®, wired and wireless remotes, BACnet®/Modbus® interfaces, and third-party thermostat adapters for seamless integration into modern HVAC systems. Though not ENERGY STAR® certified, the system still delivers efficient inverter-driven performance with a SEER2 rating of 16.1 and EER2 rating of 9.9 for dependable cooling comfort.
