Features
- Advanced Filtration System
- The MSZ-FS Series uses Triple-action Filtration: Nano Platinum Filter, Deodorizing Filter and Electrostatic Anti-Allergy Enzyme Filter.
- 3D i-see Sensor
- The MSZ-FS Series 3D i-see Sensor monitors its zone for fluctuations in temperature. If it detects an underserved area, it will temporarily direct airflow to that zone. It also enters energy saving mode if no human heat signatures are detected.
- Dual Barrier Coating
- A special coating is applied to the heat exchanger, vanes and fan to prevent hydrophilic and hydrophobic dirt build-up.
- Multiple Fan Speeds
- With multiple fans speeds like Quiet, Low, Medium, High, Super-High, Mitsubishi delivers the options that keep you comfortable.
- Hot-Start
- Mitsubishi's hot-start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
- Vane Control
- Thanks to its double vane features it separates airflow to deliver air across a large area and can simultaneously deliver to air separate sections of a room to generate a more comfortable natural airflow pattern.
- Precision Temperature Control Technology
- Inverter-driven compressor and LEV provide high efficiency and comfort while using only the energy needed to maintain maximum performance.
- H2i Technology
- H2i plus performance offers 100% heating capacity at -5 degrees and 70% to 81% heating capacity at -13 degrees Fahrenheit.
- Anti-Corrosion
- Blue Fin anti-corrosion treatment is applied to the outdoor unit heat exchanger for increased coil protection and longer life.
- Base Pan Heater
- These units feature a built-in Base Pan Heater.
- Multiple Control Options Available:
- Back-lit screen handheld remote controller (provided with unit)
- Kumo Cloud smart device app for remote access
- Third-party interface options
- (1) Mitsubishi - 12k BTU - FS-Series H2i Outdoor Condenser w/ Base Pan Heater - Single Zone Only (MUZ-FS12NAH)
- (1) Mitsubishi FS-Series 12k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-FS12NA)
- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
- Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing. We recommend locally purchased PVC hard pipe for the condensate drain on cassette and concealed duct units.
- Disconnect Box & Electrical Whip Kit - The Disconnect Box & Whip Kit provides a safe and simple way to connect your outdoor condenser to your fuse box.
- Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
- Outdoor Condenser Plastic Pad or Wall Bracket - We recommend outdoor condensers should not be placed directly on the ground. An outdoor condenser pad or wall bracket will provide a stable way to mount your condenser free from obstructions and debris.
Take hyper-heating technology to a new a whole new level with H2i plus. H2i plus systems provide 100% heating capacity down to -5 Degrees Fahrenheit outdoor ambient (without wind chill) temperature. Control your comfort with room-by-room control, a more efficient way to cool and heat your home or business. Mitsubishi Electric is the top selling brand of zoned air conditioning and heating systems. You will enjoy cleaner air and superior control of cooling, heating. In addition to being quiet, intelligent and efficient, our systems provide extraordinary service life for a lower cost of ownership. With this technology, it's simple to assign your bedrooms, kitchen, living room, office, basement and other spaces to different "zones" so each room is always comfortable. Once you decide what temperature you'd like a specific zone to be, the system will quietly maintain that temperature while using the least amount of energy needed. For additional energy savings, you have the option to not cool and heat unused rooms.

SEER2
SEER2
The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.

EER2
The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. EER2 (Energy Efficiency Ratio) is a measurement of cooling efficiency under fixed conditions. It is useful for comparing units that will operate consistently under one set of conditions (e.g. server room). The higher the EER2, the more efficient the system.
