Features
- Advanced Filtration System
- The MSZ-FH12NA 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.
- 3D i-see Sensor®
- The MSZ-FH12NA's 3D i-see Sensor® monitors its zone for fluctuations in temperature and will temporarily direct airflow to that zone. It also enters energy saving mode if no human heat signatures are detected.
- 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-FH12NA 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-FH12NA 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-FH12NA 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.

- Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
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 FH-Series 12k BTU Wall Mounted Unit
By James T
Conway, Arkansas
Purchased 02/14/2021 |
Review Posted 04/01/2021
I couldn't be happier with this unit. The remote control has various settings that allows among other features regulate the fan speed so it slowly speeds up or slows down with the preset temperature. It will also allow a person to set it on super high if you want to. On auto fan it's barely audible. I also love being able to use the remote to turn it up or down while I stay in bed. Too many features to mention.

Working Well!

Review Posted 08/12/2020
Bought this mini-split to replace an old through the wall unit in a large room which is exposed to 4 sides plus the roof. Room gets very hot in summer, as the central A/C isn't adequate. This unit keeps the room extremely comfortable and we cannot believe how quiet it is it makes virtually no noise. There are a lot of features that make this unit worth buying again. Definitely recommend!

Review Posted 07/05/2020
Adding the Mitsubishi to our historically hot bedroom has brought us much quieter and enjoyable sleep so I am really happy with the purchase. I don't have experience with other mini-split systems so don't know if this is better or worse than other products. This unit looks very modern, easily cools the space it's in, and provides a lot of cooling with very minimal noise. I am really proud to have this product in our home. The unit is installed in a 2nd story room and the 25’ line kit was perfect. The installation kit is quality and complete. I didn't need additional parts beyond the parts provided with the system and the installation kit.

This Is A Great Heater. Very Quiet.
By William J
Hatfield, Pennsylvania
Purchased 06/17/2019 |
Review Posted 10/21/2019
I have just had this running for 2 days and it heats amazing and is incredibly quiet. It replaced my failed Shinco mini split which no longer had parts available. It did produce cold air but it is now 50F outside here so I haven't tested the air conditioner much. It is next to the TV so the quietness is appreciated. The iSee sensor either blows air on you or avoids blowing air on you which is selectable from the remote control.

Very happy with my purchase!!
By Frank H.

Review Posted 07/09/2019



Bought this for my vacation home in Maine. We have window air conditioners in 3 other bedrooms but have casement windows in the master bedroom which is the warmest room in the house. I did the installation myself but called an HVAC technician to do a leak test and then draw a vacuum on the system. Added advantage is warranty coverage by having a professional complete the installation. The unit is unbelievably quiet and cools and dehumidifies the room quite well. The unit arrived in a timely fashion and the accessory kit contained everything I needed except a line cover set which I ordered separately from Amazon.
