Multi-head split systems require more careful design, commissioning, and servicing than single split systems. The refrigerant circuit serves multiple indoor heads simultaneously, and zone balancing, piping losses, and individual head capacity all interact to determine overall system performance.

Our technicians carry brand-specific diagnostic tools and have hands-on experience with the distinctive service requirements of every major multi-head system on the Melbourne market.

Multi-Zone Climate Control

We design and install multi-head systems that give each room or zone independent temperature control. From 2-zone bedroom configurations to whole-home multi-zone systems, we size and configure each installation to the specific layout of your property.

Single Outdoor Unit Efficiency

One outdoor unit serving multiple indoor heads reduces outdoor equipment footprint, simplifies maintenance access, and allows modern inverter technology to work across the full combined load. We advise on outdoor unit positioning to maximise efficiency and minimise noise impact.

Individual Head Service and Repair

Each indoor head can be individually serviced, cleaned, and repaired without taking the whole system offline. We carry parts for all major brands and can attend to a faulty or underperforming head with minimal disruption to the rest of your system.

Refrigerant Circuit Inspection

A multi-head system shares one refrigerant circuit across all indoor heads. We pressure-test the circuit, check for leaks at all indoor and outdoor connections, verify refrigerant charge, and inspect all piping runs for compliance and condition.

Zone Balancing

Unbalanced refrigerant distribution leads to rooms that run too cold while others struggle to reach set temperature. We measure supply and return conditions at each head and adjust the system to ensure equitable and efficient performance across all zones.

Control System Programming

We program zone-specific setpoints, fan speeds, scheduling, and modes on all indoor heads and configure any central control or timer systems included with the installation. We walk through the operation of each control system with you before completing the job.

A multi-head installation starts with a room-by-room load assessment. We calculate heat gain and loss for each space, then select indoor head capacities that match each room's actual requirements. We design the piping run layout to minimise refrigerant charge and pressure losses before any work begins.

ARCtick Licensed — Refrigerant Handling Compliance

All refrigerant handling on multi-head systems must be carried out by ARCtick licensed technicians. Our team holds current licence certification, ensuring all multi-head installations and refrigerant-related service work fully comply with Australian regulations.

System and Installation

What is a multi-head split system?

A multi-head split system connects two or more indoor units (heads) to a single outdoor unit. This allows multiple rooms or zones in a home to be heated or cooled from one compact outdoor unit, reducing the number of penetrations through the building fabric and the overall system footprint compared to installing individual split systems in each room.
