Who the Daikin 8.5kW is for
The FTXM85 pushes the premium Alira-generation platform to 8.5kW — one indoor unit covering what would otherwise take two mid-size splits. One install, one circuit, one remote. The from-price is a straightforward install; placement and electrical load are confirmed at a free site visit.
Sized right, 8.5kW comfortably covers around 57 m² in Perth conditions — large open-plan living/kitchen. In quiet mode the indoor unit drops to 35 dB(A). If you're between sizes, we'll tell you straight at the quote which way to go — an undersized unit runs flat-out and wears early, an oversized one short-cycles.
Daikin's large-capacity wall splits — 8kW to 9.5kW from a single indoor unit. These are the answer when one big open-plan space needs serious cooling but ducted is overkill or the roof space won't allow it. Big singles are more involved than a standard split: the dedicated circuit, wall position and airflow throw all need to be right, so the from-price assumes a straightforward install and we confirm the exact figure at a free site visit.
Installed price
What $4,455 includes
The from-price is a straightforward install — indoor and outdoor unit on opposite sides of the same wall — and it includes the whole job, not a stripped-down teaser:
- The indoor head and outdoor unit, mounted, levelled, and secured
- Up to 3 metres of insulated refrigerant pipework in neat trunking
- Electrical connection to a suitable existing circuit, with an isolating switch at the outdoor unit
- Condensate drain run to ground level
- Standard outdoor mounting (blocks at ground level, or a wall bracket where specified)
- Vacuum, pressure test, and refrigerant charge to the manufacturer's spec
- Full run test, commissioning, remote demo, and the compliance paperwork
What lifts a quote above the from-price: long pipe runs, two-storey or high mounting, tricky access, and the dedicated circuit this size requires (which we run in-house — no second electrician). The full breakdown is in our Perth split system cost guide, or get a number for your wall with the cost calculator.
The Daikin Large-Capacity range
Why we fit the Daikin Large-Capacity
Large open-plan living/kitchen zones, big rumpus rooms, and homes where ducted isn't practical.
Serious single-unit capacity
Up to 9.5kW of cooling from one wall unit — enough for 60m²+ of open-plan space in Perth conditions.
One unit instead of two
A single big split often beats two mid-size units on install cost, wall space, and having one system to maintain.
Reverse-cycle heating to match
Up to 10.3kW of heating capacity — a genuine whole-zone heater for Perth winters.
Sized and priced properly
Big-capacity installs vary more than standard splits — dedicated circuit sizing and placement matter — so the from-price is a straightforward install and the exact figure is confirmed at a free site visit.

Other Daikin Large-Capacity sizes
Daikin 8.5kW — common questions
How much does the Daikin 8.5kW cost installed in Perth?
From $4,455 inc GST, supply and installed as a straightforward install. That covers the unit, mounting, up to 3 metres of pipework, the electrical connection and isolator, and full commissioning. Longer pipe runs, height access or switchboard work lift the price — and at this capacity the dedicated circuit and placement matter more than usual, so we confirm the exact figure at a free site visit.
What size room does the Daikin 8.5kW suit?
As a Perth rule of thumb, 8.5kW of cooling comfortably handles a room of around 57 m² — large open-plan living/kitchen. Ceiling height, insulation, and big west-facing windows shift the answer, which is why we always confirm sizing at the quote.
Does the Daikin 8.5kW need its own electrical circuit?
Yes — anything above 3.5kW needs a dedicated circuit from the switchboard. Because we're dual-licensed in air conditioning and electrical, the circuit, isolator and any switchboard work are part of the same quote and the same visit — no second tradie.
What warranty does the Daikin 8.5kW come with?
Daikin 5-year parts and labour warranty, plus our own workmanship warranty on the installation. Installation by an ARC-licensed tech and a licensed electrician — the same team, on the same job — protects your manufacturer warranty; an unlicensed install is the usual reason a claim gets knocked back.
