Variable Refrigerant Flow (VRF) zoning is an energy-efficient method of providing precise comfort control to indoor environments. VRF moves refrigerant to the zone to be heated or cooled, allowing the temperature of that area to be more precisely controlled. It can simultaneously cool some zones while heating other areas or just provide comfort control to zones that are in use.

VRF offers a wide variety of applications – everything from spot-cooling or -heating a single room in a home (using a split-ductless system) to a large commercial building with multiple floors and areas (that require individual comfort control delivered by a split-zoning system).
