Choosing the right system for Double Bay
The right multi-head split systems setup for a Double Bay property depends on the building first and the brand second. One outdoor unit — ideal where balcony or yard space is limited
Our technicians work across the Eastern Suburbs every week, so the recommendation you get is grounded in what actually performs in local homes like yours — not what's sitting in a warehouse. Every quote is free, on-site and fixed in writing.
What affects the price in Double Bay
- Two Double Bay homes with identical floor areas can price thousands of dollars apart for multi-head split systems — the difference is usually zoning, access and electrical work. Multi-zone ducting, two-storey pipe runs and switchboard upgrades all add labour and materials.
- We itemise all of it on your free written quote, so you can see exactly where every dollar goes and adjust the scope to suit your budget before committing.
Local conditions in the Eastern Suburbs
- Between the surf and the harbour, eastern suburbs systems work in salt-laden, humid air nearly year-round. Protective coil coatings, stainless fixings and smart unit placement away from direct sea spray add years to a system's life here.
- Many eastern suburbs homes are renovations of older semis and terraces, where ceiling space is tight and insulation varies. That changes both the system we recommend and how the ducting or pipework gets routed.

How much does a multi-head system cost in Double Bay?
Pricing scales with the number and size of indoor heads and the pipe run lengths between them and the outdoor unit. Two-head systems start around the cost of two quality splits; the savings grow as head count rises, because you’re installing one outdoor unit instead of several. See the table below for typical fully-installed ranges.
Which brands make the best multi-head systems?
Daikin, Mitsubishi Electric and Fujitsu all offer excellent multi-head ranges with flexible head combinations and strong warranties. The right choice depends on your room sizes and how many heads you need — we design the combination during your free quote and show you options at different price points.
Common Multi-Head Split Systems jobs in Double Bay

- Pipe run lengths — multi-head systems have maximum total and per-head pipe lengths we design within
