Ductless Mini Splits

Granite State Heat Pump is a Mitsubishi Diamond Contractor. We provide effective heating and cooling solutions for residential and light commercial applications. The main product that we represent consist of Mitsubishi ductless mini-splits. There are many different aspects and options to a ductless mini-split system you can take advantage of if you’re looking for an energy efficient system to heat or cool your home or building.

If you have questions about our ductless mini-splits and would like to schedule an appointment, please don’t hesitate to get in touch with us today. We’re committed to helping you identify the perfect solutions.


Following are the the components and options you have when deciding on a ductless mini-split. All systems have an out door condenser that transfers the energy into heat or cool air and then you have the option between a wall mount, ceiling cassette or floor units. All options are great and energy efficient, but depend on your use case. If you would like to take advantage of ceiling cassettes, you will need to invest into a slim duct unit to push the air to those cassettes.

If you’re not sure what is right for you schedule an appointment with a member of our team and we’ll walk you through your different options.
