Sourcing 4-Zone Mini-Split Systems
HVACProSales helps HVAC contractors and procurement teams source 4-zone ductless mini-split systems for larger residential and commercial applications. A 4-zone system uses one outdoor condenser connected to four indoor air handlers, each independently controlled. 4-zone systems are commonly used in four-bedroom homes, commercial office suites, medical offices, and mixed-use buildings where four separate temperature zones are needed. When sourcing a 4-zone system, contractors need to specify the BTU size for each indoor unit, the total system capacity of the outdoor condenser, the refrigerant type, and the indoor unit styles required for each zone.
