Fujitsu Multi Split Systems Melbourne
A Fujitsu multi split system connects several indoor units to a single outdoor unit, so you can heat and cool multiple rooms with individual temperature control while keeping only one outdoor unit on the balcony, wall or side path. EZYAIR designs and installs Fujitsu multi split systems across Melbourne.
Who a Fujitsu multi split suits
Multi split systems suit Melbourne apartments, townhouses and homes where outdoor space is limited or where body corporate rules restrict the number of outdoor units. For a single room, a Fujitsu split system is usually simpler, and for whole home comfort through ducts see Fujitsu ducted air conditioning.
Current Fujitsu multi room ranges
The following multiple room ranges are listed on the official GENERAL Australia website at the time of writing (October 2026). The tables show the outdoor units as published.

Fujitsu multi split system FAQs
How many rooms can a Fujitsu multi split system serve?
It depends on the outdoor unit. The official specifications list the maximum number of connectable indoor units for each outdoor model, which is shown in the tables on this page. We select the outdoor unit to suit the rooms you want to condition.
Can I mix different indoor unit types on one Fujitsu multi split?
GENERAL Australia describes an extensive indoor unit line up for its multi systems. Depending on the outdoor unit, wall mounted, cassette, floor console and ducted indoor units can be combined. We confirm compatible combinations when we design the system.
Is a multi split better than separate split systems?
A multi split uses one outdoor unit for several rooms, which saves space outside and suits apartments and townhouses. Separate split systems keep each room independent. We explain the trade offs for your home.
What warranty applies to Fujitsu multi split systems?
GENERAL Australia states that it provides a 5 year full parts and labour warranty for all domestic air conditioning systems sold in Australia. Conditions are set out in the manufacturer's warranty card.
