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. The MSZ-GE12NA-8 is a wall mounted heat pump mini split indoor unit for use in single zone and multi-zone systems. The functional design is paired with quiet operations that provide comfort without disrupting your space and installing a Mitsubishi wall mounted indoor unit is quick and easy thanks to their convenient mounting plate. With multiple operating modes, multiple fan speeds, and multiple airflow directions, this unit fits the needs of nearly any room. Whether you are designing a primary heating and cooling system or supplementing an existing one, the MSZ-GE12NA-8 is an excellent addition.

Product Features

Advanced Filtration System
The MSZ-GE12NA-8 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.

Mitsubishi's hot start technology prevents cold drafts by delaying fan operation until the heat exchanger has warmed up.

Smart Set
Mitsubishi's Smart Set function allows you to save a cooling profile and a heating profile, each consisting of a temperature, a fan speed, and an airflow direction. These profiles can be activated easily with a press of the Smart Set button on the remote controller.

Econo Cool Mode
By slowly adjusting the cooling set point and swinging the horizontal vanes, the MSZ-GE12NA-8 can improve the efficiency of cooling operations without compromising the comfort provided.

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 your comfort and reduces the chance of mold growth and other property damage in the conditioned space.

Vane Control
Optimal air flow is easy to achieve with the MSZ-GE12NA-8 thanks to the vane control option. This function provides access to five different horizontal vane positions, an auto mode, and a swing mode. Auto mode selects the best vane position based on operating mode. Swing mode cycles through all positions for maximum coverage.

M-series 9000 Btu Mini Split Indoor Unit
I have installed the Mitsubishi M-Series 9000 BTU Mini Split System in my wood working shop and it does what it is supposed to do. Finally, I can work in comfort during the day when it gets hot and at night when it cools down (fall is like that in NC).

I am sure that it will be nice and warm this winter and comfortable next summer.

I use the same settings as I do in my house, 60 for heat and 75 for cool and that makes for a nice work space. With a high ceiling, 10 feet, I especially like... more

Mitsubishi M-series 9000 Btu Mini Split Condenser
The install went extremely smooth.

I have tested the unit on both cold nights and hot days (In North Carolina if you do not like the weather just wait a minute).

I was in my shop and my wife came out and wanted to know when I was going to turn the unit on to see how it works. I asked her how the shop felt and she replied "very nice and toasty". I told her that the unit was running and she had to go outside to see the fan turning ever so quietly. Then she came back in and... more

Purchased 36k Btu Quad Units
10/21/14 - I purchased the 36000 BTU quad zone with 1-18K BTU , 1- 9K i-see BTU & 2 - 6K BTU indoor units, the salesperson - Kevin Kunkel was excellent, he answered all my questions and went above & beyond to make sure my price compared to other sites were matched. He was so great that anytime I called, I only asked for him and placed my order with him over the phone. I also sent Family & Friends to deal with him only...

I did my research before contacting ecomfort,... more

Duskless Ac/heat
It's super quiet, works as noted. Would buy again, but slight damage on the unit does not seem to hamper working.

Mitsubishi Rocks!
I purchased this 24,000 BTU air conditioner/heat pump for my 3 car garage. I'm in Texas where summers are brutal and got tired of working in my garage that was akin to a blast furnace. Installed the Mitsubishi split system about a month ago and couldn't be happier. To walk in to a climate controlled garage is a joy. Even on 100+ degree days the unit cools everything down perfectly. The outside condensing unit is quiet as can be and even with it running 24 x 7, I haven't seen any difference... more

Excellent Product
This15000 BTU unit both cools and heats our 800 sq/ft. area very quickly and is unbelievably quiet. The dehumidifier setting actually lowers the humidity without freezing the house out. The remote is easy to use but for the price, a color screen would be better. Overall, I would highly recommend this model.

Well Designed, Except ....
Nicely designed & easy to use mounting system. The hole location measurements for the drain line are wrong - so measure it yourself. The incoming power box has a standard electrical connector knock-out hole with no burrs - but if you choose to run the line-set to the right (as I did) they pass directly in front of the hole making a connector impossible to use without tearing up the line set insulation or bending the lines even more extremely than they already have to be bent. Fishing the... more
