For homeowners considering a ductless upgrade, Mitsubishi Electric’s new FX Deluxe Wall-mounted Indoor Unit offers an advanced solution designed to deliver exceptional comfort, energy efficiency, and ease of use — even in extreme weather conditions.
Engineered for Performance in Any Climate
The FX Deluxe is Mitsubishi Electric’s most feature-rich indoor unit to date. With models ranging up to 24,000 BTU/h, it’s suitable for both small and large residential spaces. When paired with compatible outdoor units, including H2i® sumo™ systems, the FX delivers 100% heating capacity at outdoor temperatures as low as -10°F and maintains operation down to -22°F, ideal for cold-weather climates where traditional systems may struggle.

Energy Efficiency That Reduces Costs
This unit is ENERGY STAR® and ENERGY STAR Cold Climate certified, with SEER2 ratings up to 35 and HSPF2 ratings up to 13.3, positioning it among the most efficient ductless options available. These ratings reflect real-world performance and offer long-term savings on energy bills while minimizing environmental impact.

The FX Deluxe incorporates a range of advanced technologies designed to optimize indoor comfort:
-
3D i-see Sensor®: Monitors room occupancy and thermal conditions, adjusting airflow and temperature automatically for maximum efficiency and comfort.

Cleaner Operation, Easier Maintenance
Indoor air quality and unit performance are preserved by Mitsubishi Electric’s patented Dual Barrier Coating and Dual Barrier Fusion technologies. These features prevent the buildup of dust, smoke, fibers, and oil on internal components, reducing the need for frequent maintenance and ensuring consistent airflow and system longevity.
Thoughtful Design and Complete Control
With a sleek matte finish that resists fingerprints and scratches, the FX Deluxe blends seamlessly into modern interiors. The Dual-Vane system enables independent airflow control, making it easy to direct comfort where it’s needed most. Each unit is Wi-Fi enabled, allowing full system control via the Mitsubishi Electric Comfort Control app — from setting schedules and modes to adjusting fan speeds and temperatures remotely.
