The Mitsubishi PLA-A42EA7 / PUZ-A42NKA7 is a ceiling-recessed and is designed to be a good fit for any situation where wall mounting is not an option. With its intelligent heating and cooling features to its commercial application potential, the PLA-A42EA7 / PUZ-A42NKA7 lives up to Mitsubishi’s standards as one of the top brands in the industry.


42,000 BTU, 21 SEER

The Mitsubishi PLA-A42EA7 / PUZ-A42NKA7 is manufactured with an output of 42,000 BTU, making it suitable to be able to cover a larger room depending on climate. At 21 SEER, the unit does its job efficiently. Please note that this unit requires a cassette grille for it to be installed properly, available at an additional cost as an accessory.


Mitsubishi provides a 5 year parts and 7 year compressor warranty from the factory. When the unit is installed following your state and local codes and is registered online through the manufacturer, the warranty is upgraded to a 10 year parts and compressor warranty.

Enhanced Comfort

This Mitsubishi unit is manufactured with Inverter technology and an I-SEE sensor to constantly take temperature readings in the room it is installed when you select specific cassette grilles for installation. The system then adjusts its 4-way airflow output in the direction that it is needed most in the room. These features on the PLA-A42EA7 / PUZ-A42NKA7 allows your space to stay at a constant, comfortable temperature while staying at a superior efficiency.

Intelligent Control

The Mitsubishi PLA-A42EA7 / PUZ-A42NKA7 is designed with intelligent controls that make small adjustments to keep the room’s temperature stable and bringing more comfort to your home. While we have many Mitsubishi branded thermostats, the most useful option is their Wi-Fi accessory, the Kumo Cloud found here, allowing the unit to be controlled from anywhere that you have Internet access—from across town at work to across the world on vacation—bringing ease of access to your unit.

Durability and Reliability

Mitsubishi designed the PLA-A42EA7 / PUZ-A42NKA7 system to be durable to withstand standard weathering and general wear-and-tear. Mitsubishi also designed the unit to function at a low, -4°F temperature to give you peace of mind with the unit’s reliable warming during the colder months of the year in most climates. For a Hyper Heat pump equivalent that warms down to -13°F with the same system output, click here.


The Mitsubishi PLA-A42EA7 / PUZ-A42NKA7 can be installed in both residential and commercial applications that require a ceiling-recessed installation. The air handler is manufactured with fresh air knockouts to allow for ventilation from outside. The air handler is also fitted with ductwork knockouts for when you need more than one small room to be heated and cooled at the same time from the same unit.
