Per-ton pricing typically runs $2,200-$4,000 per ton depending on equipment and install difficulty. Assumptions: Brisbane labor and product margins converted to USD, single-storey dwelling, normal roof access.

How Size, Capacity, And Home Area Change Brisbane-Style Prices
House size and system capacity are the biggest price multipliers — each additional ton can add $2,000-$4,000 to the installed price.
Common thresholds: under 1,500 sq ft → 2–2.5 ton (lower end $6,000-$9,000). 1,500–3,000 sq ft → 3–4 ton (average $9,000-$14,000). Over 3,000 sq ft or poorly insulated homes → 4–6 ton (high $14,000-$20,000+). Longer duct runs (+50 ft) or multiple run-ups through ceilings add $500-$2,000 in labor and materials.

How Roof Type, Access, And Duct Condition Affect The Final Quote
Tight access, high roofs, or needing to replace all ductwork can raise labor and material charges by 25%–60%.
Specific drivers: roof/ceiling access — easy attic access vs. sealed tiled roof can change install time by 6–20 hours. Duct condition — reuse existing ducts (saves $800-$3,000) vs. full new duct system (adds $1,500-$6,000). Elevated condensers or crane requirements add $500-$2,000.
Practical Ways To Lower Brisbane-Style Ducted AC Prices
Controlling scope (reuse ducts, choose standard efficiency, stage work) reliably reduces the installed price.
Actions: schedule off-peak season installers for lower quotes, accept standard SEER rather than top-tier inverter models, stage installation (install indoor system first, add condenser later), and get at least three itemized quotes to compare labor hours and materials. Doing minor prep work (clearing attic space) can cut labor time and therefore labor fees.

Small jobs: 8–16 hours with a 1–2 person crew. Mid jobs: 20–36 hours with 2–3 installers. Large or complex installs: 36–60+ hours. Hourly-rate multipliers and overtime can increase costs quickly for jobs requiring weekend or rush scheduling.
