💰 Ways to save
- Insist the return-air grille is properly specced — under-sized return air is the number-one corner-cut and it starves the system, killing efficiency from day one. And watch any 'electrical if required' line: get the switchboard and 3-phase scope locked in writing, or you'll get hit mid-job (a 3-phase upgrade for a 15 kW+ system is $1,000–$2,000).
- Owner-supplying the unit can save 15–30%, but most installers then void the labour warranty on it — usually not worth the trade-off.
How we estimate this
A fully installed ducted system in 2026 mostly lands $9,000–$18,000, or roughly $80–$120 per square metre. A small 1–2 bed (7–10 kW, two zones) runs $7,000–$12,000; a typical 3–4 bed (10–18 kW, three to four zones) $10,500–$18,000; and a large 5-bed or double-storey home $17,000–$25,000+. Double-storey work carries inter-floor ductwork that alone adds $3,000–$4,000.

What a ducted air conditioning costs in Canberra
Canberra has the widest temperature swing of any capital, freezing winters and hot dry summers, so a ducted reverse-cycle system here is chosen and sized above all for a serious whole-home heating load, not just cooling. That means higher-capacity units and ductwork built to heat the entire house through a long, hard winter, which costs more than the cooling-focused ducted installs of the warmer cities, and heat-pump efficiency in the cold is the key specification.
The high local labour rates lift the fitting cost above the national figure, consistent with Canberra's dear trade market. The dry summer air makes ducted evaporative a running-cost-friendly option for the cooling half of the year, though it does nothing for the winters that drive the purchase. A licensed electrician and refrigerant-handling licence are required. For a Canberra ducted system, the heating-led sizing and the high labour base are what most shape the quote.

Frequently asked questions
How much does ducted air conditioning cost?
Mostly $9,000–$18,000 installed in 2026 — about $80–$120/m². A small home runs $7,000–$12,000, a 3–4 bed $10,500–$18,000, and a large or double-storey home $17,000–$25,000+.
Is ducted worth it over splits?
Ducted gives whole-home comfort and a cleaner look, but without good zoning it costs more to run than multi-splits. Zoning cuts its consumption 20–40% by only conditioning rooms in use, which is what makes it competitive.
What's the most common corner-cut to watch for?
Under-specced return air. A too-small return grille starves the system and wrecks efficiency from day one, so make sure it's sized properly. Also pin down the electrical scope — a 3-phase upgrade can add $1,000–$2,000.
