| Per ton equipment-only | $1,200 | $2,200 | $3,500 | Outdoor unit + basic air handler, no installation. |
Typical Total Price for a Ducted System in Brisbane Homes
For Brisbane installations converted to USD, a small ducted system (3–4 ton) usually costs $5,000-$15,000 total and a medium to large system (4–6 ton) typically runs $8,000-$18,000. Expect the average Brisbane quote to be about $9,500-$12,500 for a standard suburban house with 3–4 zones.
Assumptions: Brisbane labor norms, normal access, standard insulated ductwork, no major structural changes.
Material, Labor, Equipment, Delivery/Disposal, and Permits—What Dealers Break Down
| Cost Component | Low | Average | High |
|---|---|---|---|
| Materials (units, ducts, grilles) | $1,200 | $3,500 | $6,500 |
| Labor (install & commissioning) | $1,500 | $3,500 | $6,000 |
| Equipment (compressor, air handler) | $1,200 | $2,200 | $3,500 |
| Delivery/Disposal | $100 | $350 | $1,000 |
| Permits & inspections | $0 | $150 | $600 |
| Overhead & profit | $800 | $1,500 | $3,000 |
Materials, equipment, and skilled labor make up most of the quote—expect materials + equipment to be roughly 40–60% of the total price.
How System Size, Line Length, and Efficiency Rating Drive Price
System capacity is a primary driver: a 3-ton (36,000 BTU) system tends to be $5,000-$10,000, a 4-ton $7,000-$12,000, and a 5–6 ton $9,000-$18,000. Long refrigerant line runs over 30–50 linear feet often add $300-$1,200 for extra copper and labor.
Higher efficiency (SEER/IEER) units cost more: upgrading from a standard to a high-efficiency model can add $800-$2,500. Major duct modifications (over 200 sq ft of new duct) commonly increase labor and materials by $1,000-$4,000.
Practical Ways to Reduce the Price of a Brisbane Ducted System
Choose a correctly sized unit and limit zoning complexity—each additional zone adds $300-$800 for dampers and controls. Opting for a standard-efficiency unit and keeping duct changes minimal typically saves $1,000-$3,000.
Other tactics: schedule installation in shoulder seasons for better dealer availability, get 3+ written quotes, and prepare attic spaces or service areas to reduce labor time charged for access and cleanup.
How Installation Time, Crew Size, and Labor Rates Affect the Final Quote
Typical install time for a 3–4 ton ducted job is 2–4 days with a 2–4 person crew; larger systems take 4–7 days. Labor rates converted to USD often equate to $75-$125 per hour for skilled installers on Brisbane projects.
Expect labor hours of roughly 24–60 hours total depending on roof access, duct complexity, and number of zones. Assumptions: trained HVAC crew, typical suburban home.
Common Add-Ons and Prep Work That Appear on Brisbane Quotes
Frequent extras include zoning dampers ($300-$800 each), programmable thermostats ($150-$400 each), condensate pumps ($125-$350), and insulation upgrades ($4-$9 per sq ft). Removal of an old system or asbestos-safe disposal can add $200-$2,000 depending on complexity.
Diagnostic or call-out fees may appear as $75-$200 per trip if initial inspection is charged separately.
