Mitsubishi – Mr. Slim FX Series Wall Mount Cold Climate Indoor Unit | R-454B | Toronto & GTA Installation Included
The Mitsubishi Mr. Slim MSZ-FX Series is the premium cold climate wall mount indoor unit for Mitsubishi multi-zone heat pump systems. Featuring Mitsubishi's advanced 3D i-see Sensor®, Dual Barrier Fusion anti-contaminant coating, triple-action filtration, and built-in Wi-Fi with the Mitsubishi Comfort App — the FX Series delivers a superior level of comfort and air quality that the standard GX Series does not offer. Available in 6,000 to 18,000 BTU. Compatible with Mitsubishi MXZ standard multi-zone and PUMY commercial multi-zone outdoor units. Price includes installation of the indoor unit and up to 20 ft of lineset per head. Outdoor unit sold separately.
If budget matters more than advanced sensors and filtration, the GX Series is the right choice. If you want the best comfort and air quality Mitsubishi offers in a wall mount, the FX is worth the premium. Contact Bison Air if you are unsure.
