15,000 BTU, 22 SEER

With an output of 15,000 BTU, the MSZ-FS15NA / MUZ-FS15NA single-zone mini split can cover up to a small room in average situations. The unit is 22 SEER, providing an enhanced efficiency over other brands and making it Energy Star certified. With these features along with the Econo Cool mode, the MSZ-FS15NA / MUZ-FS15NA saves you money on your electric bills so you can save it for what you want to spend it on most.


The MSZ-FH15NA / MUZ-FH15NA 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

Mitsubishi’s condensers are all coated with Blue Fin technology, enhancing durability and lowering general wear-and-tear from wind, dust, salt, and rust. The Mitsubishi MSZ-FS15NA / MUZ-FS15NA is extremely reliable, even able to heat down to -13°F thanks to its hyper heat design with a drain pan heater. When you need it most, the unit’s powerful mode provides rapid comfort through enhanced refrigerant flow through the air handler to quickly heat or cool the room, at almost any temperature.

Superior Comfort

Mitsubishi has built its reputation on superior comfort, and the MSZ-FS15NA / MUZ-FS15NA lives up to Mitsubishi’s top-of-the-market expectations. The unit has a 3D i-See Sensor, allowing it to direct airflow where it is needed in the room instead of blasting it in a single direction. This intelligent system is complimented with optimal quad-vane control, a Smart Set function that allows you to save specific settings, enhanced dehumidification with a dry operation setting, and precision temperature control with multiple temperature sensors to make the room as comfortable as possible. On top of all of that, the MSZ-FS15NA / MUZ-FS15NA mini split uses a hot start system automatically, preventing cold air flow out of the air handler and waiting until it is warm air in the winter months. Thanks to its ability to use its own air to heat itself up, the hot start is faster to provide comfort to your home in a timely manner throughout every season.

Intelligent for Ease

When paired with the Kumo Cloud or a Cielo thermostat (sold separately), the MSZ-FS15NA / MUZ-FS15NA mini split can connect to the Internet and you can control it from anywhere in the world that you have Internet access—whether it’s across town on your way home from work or across the world for your pets.

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-FS15NA / MUZ-FS15NA single-zone mini split provides an advanced filtration system, combining deodorization, anti-allergen, and microbial break-down functions all into one idea, providing one of the most effective built-in filtration systems possible for wall mounted mini split units.
