Features
- 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.
- Econo Cool Mode
- By slowly adjusting the cooling set point and swinging the horizontal vanes, the MZ-HM24NA 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.
- 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.

- (1) Mitsubishi - 24k BTU - HM-Series Wall Mounted Unit - Single Zone Only (MSZ-HM24NA-U1)
- Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
- Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing. We recommend locally purchased PVC hard pipe for the condensate drain on cassette and concealed duct units.
- 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 units from your outdoor condenser.
- 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.
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-HM24NA 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 single zone system is the perfect combination of convenience and comfort for any heating or cooling application.

SEER2
SEER2
The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.

The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. EER2 (Energy Efficiency Ratio) is a measurement of cooling efficiency under fixed conditions. It is useful for comparing units that will operate consistently under one set of conditions (e.g. server room). The higher the EER2, the more efficient the system.
