Why Choose Elysium For Multi-Head Systems

Elysium Electrical is a licensed electrical contractor (EC16523), a member of the Electrical Contractors' Association of WA (ECA-WA), and an Accredited Master Electrician with Master Electricians Australia. With 200+ projects completed across Perth, our multi-head installations are carried out to full WA safety standards, with every job backed by a proper compliance certificate.

A multi-head system lets you condition several rooms from a single outdoor unit, with each indoor head able to be controlled independently. Our licensed electricians hold an ARC refrigerant handling licence, so the whole installation — electrical and refrigerant — is handled by the one qualified team.

Benefits Of A Multi-Head System

✓ Independent temperature control in each connected room
✓ Only one outdoor unit and one external wall penetration point needed
✓ Often more cost-effective than installing several separate split systems
✓ Energy-efficient inverter technology across the system
✓ Quiet, modern indoor head designs to suit any room
✓ Work completed by a licensed electrical contractor with ARC refrigerant handling licence

Why Professional Installation Matters

A multi-head system involves more moving parts than a single split system, and getting the sizing or refrigerant work wrong affects every room on the system. Here's why a licensed install matters:

✓ Correct system sizing — the combined capacity of all indoor heads has to suit the outdoor unit's rated combination, not just be added up loosely
✓ Correct pipe sizing and length — longer refrigerant runs to the furthest head need the right pipe diameter or performance suffers
✓ ARC-licensed refrigerant handling — connecting and testing refrigerant lines requires a refrigerant handling licence, not just an electrical licence
✓ Balanced electrical load — wiring for multiple indoor heads and controllers needs to be planned correctly, not improvised room by room
✓ Compliance certificate — every installation is backed by a proper compliance certificate

Understanding Multi-Head Systems

A few basics that help explain how a multi-head system actually works:

One Outdoor Unit, Multiple Indoor Heads

A single outdoor condenser unit connects to multiple indoor head units, typically two to five, each installed in a different room. This means only one outdoor unit and one external wall penetration point, rather than a separate outdoor unit for every room.

Independent Zone Control

Each indoor head can generally be switched on or off and set to its own temperature independently. Whether every head can heat and cool at the same time depends on the specific system — we'll confirm what your chosen model supports.

Sizing The System Correctly

Manufacturers publish combination charts showing which indoor heads can run together on a given outdoor unit. We size the system to your actual rooms rather than guessing at a combination.

Multi-Head Vs Ducted Air Conditioning

A multi-head system suits a handful of rooms needing independent control without ceiling ductwork. A ducted system suits whole-home, uniform comfort with concealed outlets. We can help you weigh up which fits your home — see our ducted air conditioning page for comparison.

Frequently Asked Questions

How many indoor heads can one outdoor unit run?

This depends on the outdoor unit's rated capacity and the manufacturer's combination chart, typically between two and five indoor heads.

Can I cool one room and heat another at the same time?

Some multi-head systems support simultaneous heating and cooling across different heads, others don't. We'll confirm what your chosen system supports before you commit.

Is a multi-head system cheaper than several split systems?

Often, yes, since only one outdoor unit and one condenser location is needed rather than a separate outdoor unit per room — though the exact cost depends on the number of heads and pipe runs involved.

Do you need a special licence to handle the refrigerant?

Yes, connecting and handling refrigerant requires an ARC refrigerant handling licence, which our team holds alongside our electrical licence.

How long does a multi-head installation take?

This depends on the number of indoor heads and the length of the pipe runs to each one. We'll give you a clear time estimate as part of your upfront quote.
