Mitsubishi Mini Split Air Conditioning system review with Matt Risinger and Al D'Andrea

In terms of technology, design, and dependability Mitsubishi ductless systems are at the cutting edge. Mitsubishi crafts systems that are built to perform well for years, offering efficient comfort for keeping your home at just the right temperature in all seasons. The major features of a Mitsubishi ductless mini-split include:

  • Install where you need it most, for the ultimate room to room comfort control
  • Easy install for additions or renovations
  • Great for homes with no space for additional ductwork
  • Systems are highly efficient, using 25-40% less energy to cool your home
  • Advanced allergen filtration system
  • Solves hot and cold spots in your home
  • Wirelessly control comfort from any place at any time


Indoor units allow you to create individual comfort zones.

Control the temperature within any space using a wall, ceiling or floor mounted indoor unit — whichever works best for the specific room or area. You can fine-tune your comfort while you save money by cooling or heating only the spaces you use. Single rooms can now have ultimate comfort with the power of precise control over hot and cold spots.


Slim, wall-mounted units provide individual room comfort control. Perfect for room by room hot/cold spot control.



Wider airflow pattern for better air distribution in less obtrusive style. Perfect for bedrooms, offices, sunrooms and additions.
