Increase the efficiency of any existing air handler on the market by connecting it to our single phase Willis mini VRF outdoor unit and controlling it with our AHU kit (external modulating system). Up to 21.5SEER / 11.5 HSPF
Add any type of ductless indoor system in the rooms that we're always too cold or too hot and connect it to the same Willis mini VRF outdoor unit as your air handler(s). No more comfort issues caused by poor ductwork sizing.
Replace several unitary outdoor units with one smaller, more powerful and more efficient single phase mini VRF. We can control several air handlers with our state of the art Willis AHU kit.
Upgrade your existing system without replacing your indoor air handlers. The outside unit will always sustain more wear and tear and therefore many indoor units are still in perfect condition when you have to replace your outside system.
The outdoor unit is ultra quiet and the side discharge technology will help you save some space when you compare with conventional top discharge less efficient systems.
