All of our split systems, whether single zone or multi zone, are inverter driven air-source heat pumps*. Split systems are often used in residential applications in lieu of a central forced air system, for the purposes of better efficiency, better zoning, or of heating a home using air-source heat pump instead of using oil, propane or natural gas. Split systems are also used in commercial applications, often to compliment the buildings main HVAC system (VRV or other). Our expertise in split systems ranges from small wall mounted splits for elevator rooms, all the way to hundreds of split systems for large multi-residential projects.
