Daikin Multi Split Systems Melbourne

A Daikin multi split system connects several indoor units to one outdoor unit, so you can heat and cool multiple rooms with independent control in each. EZYAIR designs and installs Daikin multi split systems across Melbourne, from two bedroom apartments to large homes.

Who a Daikin multi split suits

Multi split systems suit Melbourne apartments, townhouses and homes with limited outdoor space, and homes that want to add rooms later within the capacity of the outdoor unit. For a single room, a Daikin split system is simpler. For whole home comfort through ducts, see Daikin ducted air conditioning.

Current Daikin multi split ranges

The following ranges are listed on Daikin Australia's residential multi split page at the time of writing (October 2026).

How we install a Daikin multi split system in Melbourne

  1. Enquiry and assessment. We discuss the rooms you want to heat and cool, then assess the home, including room sizes, insulation, windows and orientation, and where the indoor and outdoor units can go.
  2. Recommendation and written quote. We recommend a Daikin multi split range and capacity that suits the home and explain the options before you commit.
  3. Installation. Our team installs the indoor and outdoor units, runs the refrigerant pipework and condensate drain, and completes the electrical connection as required by Victorian regulations.
  4. Commissioning and handover. We test heating and cooling operation, set up the controller and show you how to use the system and look after the filters.
  5. Ongoing service. Regular maintenance keeps the system running efficiently. See our maintenance services.

Manufacturer warranty

Daikin Australia states that "Daikin's 5-year parts and labour warranty applies to split, multi split and ducted air conditioners purchased and installed in homes across Australia" (Daikin Australia). Warranty periods, coverage, conditions and exclusions are set out in the Daikin Manufacturer's Warranty Card on the Daikin warranty page.

Victorian Energy Upgrades

EZYAIR is a Victorian Energy Upgrades (VEU) accredited provider (accreditation A2261). If you are replacing an older heater with an efficient reverse cycle system, ask us whether your project may be eligible for a VEU discount. Eligibility depends on the existing heater, the new product and the program rules at the time. Learn more on our Victorian Energy Upgrades page.

You can see a range of wall hung, cassette, ducted, bulkhead and floor console units on display, many of them operational, at our Burwood showroom at 49 Huntingdale Rd, Burwood VIC 3125.

Daikin multi split system FAQs

How many rooms can a Daikin multi split system serve?

Daikin states that Super Multi NX can serve up to five rooms from one outdoor unit, and VRV IV-S can connect as many as 14 indoor units. The exact number depends on the outdoor unit and the indoor units selected.

Can I mix wall mounted and ducted units on a Daikin multi split?

Yes. Daikin lists wall mounted, bulkhead, ducted and cassette indoor units for Super Multi NX, and bulkhead and ducted indoor units for VRV IV-S. We confirm compatible combinations when we design the system.

Is a multi split suitable for a Melbourne apartment?

Often, yes. Daikin notes that multi split systems suit apartments, townhouses and houses with limited outdoor space, because one outdoor unit serves several rooms. Body corporate approval may be needed for the outdoor unit location.

What warranty applies to Daikin multi split systems?

Daikin Australia states that its 5-year parts and labour warranty applies to split, multi split and ducted air conditioners purchased and installed in homes across Australia. Full conditions are in the Daikin Manufacturer's Warranty Card.
