Key Features

  • HEALTHIER INDOOR AIR - Sophisticated multi-part filtration systems reduce contaminants such as allergens, viruses and bacteria from the air.
  • PERFORMANCE IN COLD CLIMATES - Hyper-Heating INVERTER® technology provides exceptional performance down to -13° F outdoor ambient, with 100% heating capacity at 5° F outdoor ambient.
  • WHISPER-QUIET OPERATION - Both the indoor and outdoor units are extremely quiet. Indoor units operate as low as 19 dB(A) - that's quieter than a whisper.
  • HIGHLY-EFFICIENT INVERTER TECHNOLOGY - Traditional systems operate on an inefficient cycle of 100% on or 100% off. With Mitsubishi Electric’s INVERTER-driven compressor technology, our systems constantly measure conditions and then adjust compressor and fan speed up or down to maintain the desired temperature.
  • EASY-ACCESS, WASHABLE FILTERS - Front panels make it easy to access the filters. Instead of wasting money on new filters several times a year, Mitsubishi Electric indoor units use easy-to-clean, washable filters. You’ll never get caught without a filter again.
  • HOT-START TECHNOLOGY - With Hot-Start technology and multi-vane airflow, you get hot air right away and rapid heating of the room.
  • REMOTE CONTROL - Wireless controllers are available to program the system around your comfort level and your life's busy schedule. Whether you’re gone for the day or on an extended vacation, you can control your system from just about any smartphone or tablet. You’ll never again have to return to a house that’s freezing cold or blazing hot.
