Multi-Zone Systems

Multi-zone ductless mini split systems connect a single outdoor condenser to multiple indoor units, allowing independent temperature control in several rooms or zones. They’re ideal for whole-home zoning, multi-room renovations, and light-commercial spaces.

Each system is defined by zone count, total BTU capacity, and approved indoor unit combinations. Correct matching ensures balanced performance, quiet operation, and long equipment life.

• Serve 2–5+ indoor zones from one outdoor unit
• Mix wall mounts, cassettes, and consoles (model-dependent)
• Independent room temperature control
• Reduced outdoor equipment footprint

Selection checklist: total connected BTUs vs condenser capacity, number of zones, indoor unit styles, max line length, elevation limits, voltage, and low-ambient heating capability.

Pro tip: Avoid over-connecting indoor capacity beyond manufacturer limits. Balanced zoning improves comfort and prevents compressor strain.
