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. Mitsubishi is committed to achieving total customer satisfaction and year after year they do just that. The MZ-GL18NA is backed by a 5 year parts and 7 year compressor warranty to show you they stand by their product. With an included wireless remote controller, this system is the perfect combination of convenience and comfort for any heating or cooling application.
  • Advanced Filtration System
  • The MSZ-GL18NA-U1 combines a hybrid catechin deodorizing filter with an enzyme-based filter for managing allergens. The anti-allergy filter not only captures the offending particles, it also breaks them down, cleaning the air as it is conditioned.
  • Hot-Start
  • Mitsubishi's hot start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.
  • Econo Cool Mode
  • By slowly adjusting the cooling set point and swinging the horizontal vanes, the MSZ-GL18NA-U1 can improve the efficiency of cooling operations without compromising the comfort provided.
  • Dehumidification
  • When the indoor unit is run 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.
  • Multiple Vane Control Options
  • Auto mode selects the best vane position based on operating mode, and the swing modes cycle through all positions for maximum coverage. When wide mode is activated, fan speed increases beyond the current setting.
  • Kumo Cloud Compatible
  • Control every zone in your home from the palm of your hand. The Kumo Cloud App allows easy access and control with any smartphone or internet browser.
  • Precision Temperature Control Technology
  • The outdoor condenser is equipped with inverter technology and an electronic linear expansion valve. These components improve temperature accuracy and system efficiency through precise adjustments of both compressor speed and refrigerant flow.
  • Blue Fin Condenser
  • Condensers are constantly exposed to wind, dust and salty air that take their toll on your unit. Mitsubishi coats their condensers with an anti-rust coating to extend its lifespan.
  • Smart Set
  • Mitsubishi's Smart Set function allows you to save a cooling profile consisting of a temperature, a fan speed, and an airflow direction. This profile can be activated easily with a single press of the Smart Set button on the remote controller.
  • Product Includes
    • (1) Mitsubishi GL-Series 18k BTU Wall Mounted Unit - For Multi or Single-Zone (MSZ-GL18NA-U1)
    • (1) Mitsubishi - 18k BTU - GL-Series Outdoor Condenser - Single Zone Only (MUZ-GL18NA-U1)
    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 (Optional) - This pad provides an even surface, free of debris, on which to place your outdoor condenser.
    • Wall Bracket (Optional) - The outdoor mini split wall bracket is a simple and sturdy way to mount your outdoor condenser off of the ground.
    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.

Product Q&A

Does the unit automatically shut off once the set temperature is reached, or does it just run constantly?
Lindsay 
from Texas 
July 30, 2016
Read Response +
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.
Hide Response -
Does the unit have the ability to dehumidify without cooling? I'm looking at a possible install in my basement, where it can get hot in the summer, but sometimes it's just too humid. I'd like if I don't have to keep a separate dehumidifier too.
Anthony 
from Pennsylvania 
July 20, 2016
Read Response +
Answer
Mitsubishi GL-Series units include a Dry Mode that is designed to remove moisture from the space the unit is installed in. This feature runs the unit at a low speed to remove moisture from the air. You may experience some cooling of the space while the unit is operating in Dry Mode.

Depending on how damp your space is, The system may not entirely eliminate the need for a dedicated dehumidifier, but it should help keep the space relatively dry in all but the most extreme conditions.
Hide Response -
Is this unit, along with other M series units, pre charged with the refrigerant?
Bill M. 
from Massachusetts 
July 15, 2016
Read Response +
Answer
The outdoor unit comes pre-charged for use with line sets up to 25 ft. in length. Additional refrigerant will be needed if you are using a longer line set

I'm interested in hearing about the heating element in this unit. We live in northern Virginia. It's not like living in Ohio or Chicago, but it can stay below freezing for a couple of weeks at a time.
Chris 
from Virginia 
May 17, 2016
Read Response +
Answer
Thanks for your question. The unit doesn't have a heating element - it runs as a heat pump so it absorbs heat from the outdoor air and brings it inside (like an air conditioner running in reverse).

For colder climates, Mitsubishi's H2i product is a better option, as it can run in heating mode at lower outdoor temperatures. The equivalent H2i product to this is the MZ-FH18NA. It'll run at 100% of its rated output down to 5 degrees F, and will continue to operate effectively as low as -13F.

It's recommended that a drain pan heater be installed with the unit to prevent it from freezing during cold-weather operation.
Hide Response -
If I put the remote control on my night stand, then, will the remote take a temperature reading at the night stand and run the indoor unit until the remote is satisfied?
Jon 
from Washington 
April 27, 2016
Read Response +
Answer
The M-Series indoor unit reads the temperature at the indoor unit, not at the remote. If you want to detect the temperature at a location other than the unit a remote sensor is available, but will need to be hardwired.
