Ductless Heating and Cooling Solutions

Ductless cooling and heating technology offers an energy-efficient, easy-to-install alternative to traditional ducted systems. It focuses on individual rooms and living spaces rather than one central system.

Ductless technology is the perfect solution for:

  • Homes with rooms that are either too hot or too cold
  • Additions/Renovations
  • Enclosed patios/Sunrooms
  • Garage and basement workshops or studios
  • Homes without space for ductwork

Ductless Mitsubishi ElectricSingle and multi-zone applications available with flexible installation options. The indoor units can be installed anywhere in the room – the wall, ceiling, or floor. The outdoor units come in a variety of capacities and are compact for ease of installation.
