Features
    For over 50 years, Mitsubishi has remained at the forefront of the mini split industry thanks to their dedication to providing efficient, user-friendly comfort solutions. Part of Mitsubishi's hyper-heating product line, the MZ-FH18NA is a packaged single zone heat pump mini split system designed to bring high-efficiency zoned comfort to homes in frigid climates. The wall mounted indoor unit, MSZ-FH18NA2, boasts a functional design, and operates at volumes as low as 32 dB. Thanks to the included mounting plate, it is easy to install on nearly any wall. The outdoor condenser uses some of the most advanced technology available to modulate temperature without the energy-wasting overshoots and short-cycling associated with simpler systems. With an included wireless remote controller, this system is the perfect combination of convenience and comfort for any application in a sub-freezing environment.
  • Precision Temperature Control Technology
  • The MUZ-FH18NA2 outdoor condenser includes inverter technology and an electronic linear expansion valve. By adjusting compressor speed and refrigerant flow, output can be matched to the zone for precise temperature control and improved efficiency.
  • i-see Sensor 3D
  • The MSZ-FH18NA2's i-see Sensor 3D monitors its zone for fluctuations in temperature. If it detects an underserved area, the MSZ-FH18NA2 will temporarily direct airflow to that zone. It also enters energy save mode if no human heat signatures are detected.
  • H2i Technology
  • Low or negative ambient temperatures don't bother the MUZ-FH18NA2. It is rated for 100% heating capacity at 5 degrees F and 73% at -13 degrees F.
  • Advanced Filtration System
  • The MSZ-FH18NA2 uses two advanced filters to clean and deodorize the circulated air. The deodorizing filter absorbs any offending smells, while the second is an enzyme-based anti-allergy filter that captures and destroys bacteria and particulates.
  • Hot-Start
  • Mitsubishi's hot start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
  • Powerful Mode
  • The powerful setting on the MSZ-FH18NA2 makes it easy to get your zone to the perfect temperature quickly. When activated, the unit temporarily increases refrigerant flow and fan speed to provide quick comfort through rapid heating or cooling.
  • Econo Cool Mode
  • By slowly adjusting the cooling set point and swinging the horizontal vanes, the MSZ-FH18NA2 can improve the efficiency of cooling operations without compromising the comfort provided.
  • Dehumidification
  • When the indoor unit runs in dry mode, the coil's temperature stays just below the dew point of the return air, removing unwanted moisture. This improves comfort and reduces the chance of mold growth and other property damage in the conditioned space.
  • Vane Control
  • Optimal air flow can be achieved with the MSZ-FH18NA2 thanks to two vane control options, standard and wide. Auto mode selects the best vane position based on operating mode while swing mode cycles through each vane position.
  • Product Includes
    • (1) Mitsubishi - 18k BTU - FH-Series H2i Outdoor Condenser - Single Zone Only (MUZ-FH18NA2)
    • (1) Mitsubishi FH-Series 18k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-FH18NA2)
    Product Note
    This product requires the following accessories for installation:
    • Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor unit.
    • Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor unit to drain locations of your choosing.
    • 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 unit from your outdoor condenser.
    • Base Pan Heater - The base pan heater prevents ice from building up on the outdoor unit. Excessive ice build will lead to performance issues and could damage your unit.
    • 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.
    Adding these accessories to your order will provide a complete, ready-to-install mini split system. Our convenient Mini Split Installation Starter Kits include all of the required accessories listed above. Starter kits can be added to your order from the accessories tab above.

Mitsubishi MZ-FH18NA Reviews & Ratings

Product Q&A

Search Product Q&A's Answered by Chris, the eComfort Product Expert
icon-social-fb1
+
Are the filters washable?
Douglas H 
from Alabama 
July 10, 2017
Answer
The Mitsubishi MZ-FH09NA system has 3 different filters each with slightly different maintenance requirements. The primary air filter should be either vacuumed or rinsed with water every other week, the anti-allergen filter should be vacuumed or rinsed with warm water every 3 months, and the deodorizing filter should also be vacuumed or rinsed with warm water every 3 months.  The latter two filters will also need to be replaced periodically. Complete details about filter maintenance and replacement can be found in the operation manual on page En-11.
+
What is recommended square footage for this FH06 model?
Anton 
from Virginia 
October 07, 2016
Answer
Sizing depends on a number of factors besides the size of the room being heated or cooled. These include the quality of insulation, the number and size of the exterior walls, the size and quality of the windows, and the climate among other factors. To provide the best estimate possible we recommend using our Mini Split Sizing Wizard.
+
What wall mounted programmable control options are there for the MZ-FH systems?
Adam 
from Massachusetts 
August 11, 2016
Answer
You can use three different adapters / controls to program the wall mounted unit:

1) Mitsubishi RedLINK - Wireless Remote Controller Kit - #MHK1
2) Mitsubishi - Thermostat Adapter - #PAC-US444CN-1
3) Mitsubishi Kumo Cloud Wi-Fi Adapter - #PAC-WHS01WF-E

The first option has the thermostat included. The second option will require your own thermostat. The third option will require a smartphone or tablet.
+
Does the unit automatically shut off once the set temperature is reached, or does it just run constantly?
Lindsay 
from Texas 
July 30, 2016
Answer
This system is designed to run constantly to maintain the set temperature. Once it reaches the set-point, both the outdoor unit's compressor and the indoor unit's fan slow to a reduced speed. The ability to slow down the compressor is one of the major benefits of inverter technology. It helps efficiency because compressor startup uses disproportionately more energy than operation.
+
In which temperatures can it do the cooling and heating?
Nihan 
from Hawaii 
July 22, 2016
Answer
In the cooling mode, the system can operate in outdoor temperatures between 14° F and 115° F.

In the heating mode, the system can operate in outdoor temperatures between -13° F and 75° F. It can deliver up to 100% of the rated heating capacity at 5° F.
+
Can this unit be used for a business?
Joe 
from New York 
December 30, 2015
Answer
Yes, there is no reason the Mitsubishi M-series units can't be used in an office or store front. However if you are using the unit to cool equipment, such as a server, that requires cooling 24 hours a day 365, I would suggest using a Mitsubishi P-Series unit. These are more robust and will perform better under these conditions than the M-Series units.
+
Is this unit both a heat source and AC?
Russ 
from Washington 
November 16, 2015
Answer
Yes, the Mitsubishi MZ-series heat pump system will provide both cooling and heating for your space. In fact, the FH is the Hyper-Heating product that will be able to provide heat while outdoor temperatures reach down to -14F.
+
Do these come with FREON / Refrigerant straight from the factory?
Michael 
from Colorado 
November 16, 2015
Answer
Yes, Mitsubishi single zone heat pumps will come pre-charged with enough R-410a refrigerant for up to 25' of lineset. The system will need to be purged and vacuumed prior to releasing the refrigerant. If the pipe length exceeds 25', your installer will need to add additional refrigerant.
+
I have 11' walls. How high should I mount the indoor unit?
Bill 
from Washington 
November 16, 2015
Answer
You can install Mitsubishi Wall Mounted indoor units anywhere between 63" from the floor to 3" from the ceiling. Generally, you'll want to install the indoor unit high on the wall where air can distribute over the entire room.
