    This product requires a compatible outdoor condenser for functionality. 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.
  • 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-HM indoor unit 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.
  • Product Note
    This product requires a compatible Mitsubishi outdoor condenser and the following accessories for indoor unit installation:
    • 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.
    • Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
    • Adding these accessories to your order will provide a complete, ready-to-install mini split system.

    Mitsubishi products include a 10-year warranty with the requirement that installation is completed by a licensed contractor and that the product is registered at within 90 days of installation.
