12,000 BTU, 23.1 SEER

At 12,000 BTU, the MSZ-GL12NA / MUZ-GL12NA is generally suitable to heat and cool a small room in many climates. With a 23.1 SEER rating, the unit has a superior electrical efficiency than most central systems and is Energy Star certified. This efficiency combination makes it able to be installed across all mainland US states. Moreover, Mitsubishi’s special Econo Cool mode adjusts the cooling points on the air handler and sweeping vanes, improving both efficiency while providing faster temperature changes.


The MSZ-GL12NA / MUZ-GL12NA comes with Mitsubishi’s standard 5 year parts and 7 year compressor warranty out of the box, and when the installation follows your state and local codes and you register the unit online through the manufacturer, it becomes a 10 year parts and compressor warranty.

Durability and Reliability

The Mitsubishi MSZ-GL12NA / MUZ-GL12NA single-zone mini split has a Blue Fin condenser design, making it resistant to wind, dust, salt, and rust to exponentially extend its lifespan. The unit functions down to -4°F, allowing you to be able to rely on the unit when you need it most.

Superior Comfort

The Mitsubishi brand offers superior comfort to its customers, offering the MSZ-GL12NA / MUZ-GL12NA with its top-brand enhancements. The unit is a hot-start model, meaning that the unit will not blow cold air into the room if it calls for heat, waiting for the heat exchanger to be ready to heat prior to operation. The unit also offers a dry mode, providing an enhanced dehumidification over other brands.

Intelligent for Ease

Mitsubishi’s MSZ-GL12NA / MUZ-GL12NA mini split uses its Smart Set technology to provide a consistent temperature by variating airflow, direction, and air temperature output. When paired with the Kumo Cloud or one of the Cielo thermostats, the unit can connect to the Internet and you can control it from anywhere in the world that you have Internet access. The MSZ-GL12NA / MUZ-GL12NA’s air handler also uses its own air to heat itself up, quickly and efficiently providing heat to your home so that you are comfortable faster.

Health in Mind

Mitsubishi does not stop at a superior comfort; it is also concerned with the health of whomever uses the unit. The MSZ-GL12NA / MUZ-GL12NA single-zone mini split provides an advanced filtration system, combining deodorization, anti-allergen, and microbial break-down functions all in one, enhanced filtration system.

Very good heater/air conditioner
Purchased the Mitsubishi unit due to the reputation and reviews on it. The unit has performed great thus far (about 1.5 months since install). It is super quiet, keeps room at even temp, and is easy to control via the remote.
