Mitsubishi ST Series Ductless Air Conditioner – these large capacity standard wall-mounted units have Wide Airflow capabilities to ensure air reaches every corner of a room and includes the Powerful Mode feature for rapid cooling and heating. Options include a single-zone, cooling only model for climates where heating is unnecessary.

The less sophisticated, conventional air conditioning and heating systems run at full power until it reaches a set temperature and then stops, only to turn on again — usually 3 to 5 times per hour — as the temperature becomes uncomfortable. Each time a conventional, non-inverter driven system turns on, it may use more energy than it does while running.

The INVERTER, at the heart of our system, eliminates the wasteful start and stop cycle. Just as your heart always beats, but automatically beats faster when you exercise, the system is always active with the INVERTER enabling it to automatically adjust conditioning when its temperature sensors detect even subtle changes. You don’t have to think about it and the system is so quiet you won’t hear it either. Rooms are cooled and heated faster and more efficiently. The INVERTER regulates energy consumption so that the system only uses the precise amount of energy needed to keep each room at the temperature you choose. This is greener and more sustainable than running at full power like conventional systems and can reduce energy consumption by up to 40 percent.

Installs quickly and easily, without the need for major construction and remodeling. Mitsubishi ST Series Ductless Air Conditioner wall-mounted units are the most versatile and popular style of indoor units. Slim, stylish and equipped with filters to continuously clean indoor air, these units sit high on the wall and are ideal for conditioning smaller areas such as individual rooms in a home, office or store. This indoor unit option does not require ductwork.

Realizes maximum control and energy efficiency by cooling and heating only those spaces in use

Complete comfort control of temperature, fan speed, and air direction in each room or zone via kumo cloud® or other smart home devices.

Our indoor units don’t just keep each room in your home at the perfect temperature; they continuously clean the air of allergens, dust, viruses and bacteria. Each room’s indoor unit is equipped with filters to directly improve your air quality while the conventional system has only one filter installed in the central unit. The filters are washable and last up to 10 years, which saves you money on maintenance. Filters available for our indoor units include:

  • Nano Platinum Filter – This filter incorporates nanometer-sized platinum-ceramic particles that kill bacteria and deodorize air.
  • Deodorizing Filter – These platinum deodorizing filters use nanotechnology to absorb odors and neutralize the worst smells.
  • Anti-Allergy Enzyme Filter – This electrostatic, anti-allergy enzyme filter uses an enzyme catalyst to break down allergen proteins and transform them into non-allergen proteins. That means lose the sneezing, but keep the cat
