Mitsubishi's commercial 42,000 BTU Ceiling Suspended single zone heat pump (PCA-AK42NL & PUZ-AK42NLHZ) is part of Mitsubishi's P-series. This single zone unit is perfect for larger retail stores, classrooms, restaurants and other business and commercial applications.

Mitsubishi Electric created the P-series systems for commercial applications. P-series systems like the PCA-AK42NL & PUZ-AK42NLHZ are built with more durable materials, meant to survive through dirtier, high trafficked environments. Additionally this comes with a Hyper-Heating outdoor unit that can heat effectively down to -13F.

This 42,000 BTU ceiling suspended single zone heat pump is super efficient and built to make sense for your business. It provides low ambient cooling down to 0 degrees Fahrenheit, and can cool continuously for 24 hours in the harshest conditions. It also has filter light indicators for maintenance reminders and has an outside air intake option!

This product version uses the new R454B refrigerant.
