It's the hot new thing in heating! Mitsubishi Electric has redefined the heat pump, enhancing their INVERTER-driven heat pumps with advanced Hyper-Heating INVERTER(H2i®) technology for year-round comfort in a single system. These innovative heat pumps can operate effectively to deliver toasty warm comfort at outdoor temperatures well below zero.

This Mr. Slim Hyper Heat inverter-driven wall-mounted ductless system is ideal for conditioning bedrooms, living rooms, dining rooms, garages, basements, kitchens, bonus rooms, out buildings, and more. These ultra-efficient Hyper Heat systems are also powerful and ideal for extreme climates, providing close to full-capacity heating at ambient temperatures as low as 5°F. MUZ-FE/MSZ-FE systems are Energy Star rated, With this system having a cooling capacity of 18,000 BTU, a heating capacity of 21,600 BTU, and a 20.2 SEER.

Control Options
The MUZ-FE/MSZ-FE systems also offer the optional wireless, RFI-RedLINK™ enabled, full-function wall mount controller, allowing homeowners to control their unit from a remote PC, smartphone or tablet (MHK1 sold separately). If you prefer a standard, fully wired and functioning wall mount control, this system also works with the PAR-31MAA (sold separately and requires MAC-333IF).

INVERTER Technology
The M-Series INVERTER-driven compressor and linear expansion valve (LEV) works with the system’s sophisticated electronic controls to detect temperature changes in a room or zone, automatically changing speeds to adjust for precise capacity and temperature control.

Air Filtration
The indoor units use a sophisticated multiple filtration system to ensure clean, healthy air throughout the rooms/zones they condition. The Hybrid Catechin washable pre-filter captures dust and eliminates odors, while the Blue Enzyme washable filter uses an enzyme catalyst to capture and eliminate allergens, germs, bacteria, and viruses.

Quiet Operation
Mr. Slim Indoor Units operate at very low sounds levels (19-34 decibels). According to a study performed by the National Institute for Occupational Safety and Health, Mr. Slim Indoor Units are quieter than a human whisper (30 decibels) at low speed.

Rare Earth Magnet Rotor
Mr. Slim MSZ-FE Series H2i units feature compressors with a rare earth magnet rotor, which increases the magnetic flux and reduces the compressor's energy consumption, while producing more heat.

Additional Features & Benefits

  • Auto fan speed feature plus four speed settings available (Low, Medium 1, Medium 2, High)
  • Wide discharge vane and Swing Mode feature provides up to 150° horizontal air flow coverage
  • Wireless handheld remote controller included

How many BTUs do I need for my ductless split?

Please Note: Mini Split Systems must be installed by a licensed Contractor with an EPA Refrigerant Certification to qualify for warranty.

(BTU ratings are estimates only, based on 10ft ceilings, with great insulation and windows. Some factors may alter this calculation: lack of insulation, heavy sun, excessively hot regions, & tall ceilings)

9,000 BTU       350 sqft
12,000 BTU     500 sqft
18,000 BTU     750 sqft
24,000 BTU     1,000 sqft
30,000 BTU     1,250 sqft
36,000 BTU     1,500 sqft

Make sure you install a unit that is going to properly cool your square footage. An over-sized air conditioner is actually less effective — and wastes energy at the same time. Air conditioners remove both heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.

How much heat can this really generate?

We know a lot of people are interested in using ductless splits as their year-round system, and the Mitsubishi Hyper Heat series is among the best in providing heating capability even at very low temperatures. This system is capable of heating a 750 sq foot space at fully 100% capacity even at 5 degrees Fahrenheit. At negative 13 degrees F, this system can still provide heat at 73% capacity. This system performs extremely well in cold environments, with performance in heating mode of -13*F to 75*F and in cooling mode from 14*F to 115*F.

Which line set kit do I need?

This unit uses a 3/8" x 5/8" line set. These are sold separately, and you can choose from our 15 ft, 25 ft, and 50 ft lengths. The length needed depends on the needs of your project and how you will set up the system (distance from outdoor condenser to indoor air handler).

Can I install this myself?

While installation of a ductless split is much easier than a central air system, it's still much more advanced than installing a window unit or portable. Furthermore, the manufacturer warranty is only valid if a licensed professional does the installation. So while it is possible to do the installation yourself, we strongly recommend you hire an HVAC professional in your area.

Is this backed by a warranty?

Yes, it comes fully backed by a manufacturer's warranty, and ComfortUp is an authorized online seller of these systems. Our customer support team will provide assistance should you ever need to file a warranty claim with the manufacturer. Please be aware that only systems that are installed by a licensed HVAC contractor are backed by the warranty. Proof of licensed installation is required. The receipt/invoice from the contractor should be sufficient.
