15,000 BTU, 17.7 SEER

With an output of 15,000 BTU, the SLZ-KF15NA / SUZ-KA15NAHZ system is designed to be able to cover up to a small room in ideal climates. At 17.7 SEER, Mitsubishi designed the unit to provide efficient heating and cooling to your home at a moment’s notice. Please note that the image shows an I-SEE sensor in the cassette grille, available at an additional cost. Without this upgrade, the grille will not include the enhanced functionality of more precisely redirecting the airflow of the unit.


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

With its Inverter technology and constant temperature reading system, the SLZ-KF15NA / SUZ-KA15NAHZ is designed to automatically ramp up and down depending on the room’s temperature requirements on a constant basis, keeping you as comfortable as possible in your home.

Intelligent Control

The Mitsubishi SLZ-KF15NA / SUZ-KA15NAHZ is designed with intelligent controls that make small adjustments to keep the room’s temperature stable and bringing more comfort to your home. With an optional WiFi accessory, such as the Mitsubishi Kumo Cloud Adapter found here, this unit can be controlled from anywhere that you have Internet access—from across town at work to across the world on vacation—bringing ease of control to Mitsubishi’s superior comfort.

Durability and Reliability

Mitsubishi designed the SLZ-KF15NA / SUZ-KA15NAHZ system setup to be durable to withstand standard weathering and lower general wear-and-tear. With its Hyper Heat technology, Mitsubishi also designed the unit to heat down to -13°F temperature to give you peace of mind with the unit’s reliable warming during the coldest months of the year.
