Mitsubishi PAA-BA30NL & PUZ-AK30NLHZ 30,000 BTU 17.6 SEER2 Cased Coil Hyper Heat Pump System - R454B

Mitsubishi PAA-BA30NL & PUZ-AK30NLHZ: 30,000 BTU Hyper-Heat Split System

The Mitsubishi PAA-BA30NL indoor cased coil paired with the PUZ-AK30NLHZ outdoor Hyper-Heat heat pump delivers exceptional year-round heating and cooling performance for residential and light commercial applications. Designed for compatibility with gas furnaces and Mitsubishi intelli-HEAT® systems, this 30,000 BTU Hyper-Heat split system combines advanced inverter-driven technology, extreme low-temperature heating capability, and flexible installation options to provide dependable comfort in virtually any climate. Ideal for homes, offices, retail spaces, and retrofit HVAC projects, the system delivers reliable efficiency and powerful heating performance even during severe winter conditions.

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. This feature allows the system to automatically transition between heat pump and furnace operation based on outdoor temperatures, energy efficiency preferences, or carbon reduction goals. 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 orientations, making it adaptable to a wide range of installation requirements. With airflow up to 1,024 CFM, the indoor coil provides consistent air distribution and enhanced comfort throughout the conditioned space.

The PUZ-AK30NLHZ outdoor unit utilizes Mitsubishi’s H2i® Hyper-Heating technology to provide 100% heating performance down to 5°F and guaranteed heating operation down to -13°F. Flash Injection technology helps maintain optimum compressor performance during extreme cold weather, while the built-in base pan heater helps prevent ice buildup and ensures reliable winter operation. The inverter-driven twin rotary compressor continuously adjusts output to match demand, improving comfort and reducing energy consumption. Blue Fin anti-corrosion coating and Seacoast Protection help safeguard the outdoor heat exchanger from salt, sulfur, and airborne contaminants that can impact performance and longevity. Despite its powerful output, 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.

ENERGY STAR® certification and high-efficiency operation help reduce energy costs while maintaining dependable comfort throughout the year. The system also supports a wide range of advanced control options, including Mitsubishi’s Comfort app, kumo cloud®, wired and wireless remote controllers, thermostat interfaces, BACnet®/Modbus® integration, and remote sensing accessories for flexible comfort management and system monitoring.
