What drives ducted cost
Ducted systems are priced around the total cooling/heating capacity your home needs, the ductwork and zoning, roof or ceiling access, and any electrical upgrades. Larger homes, more zones and difficult roof space all push the quote up, so the sourced range above is a starting point, not a quote for every house.
Running cost
Running cost is separate from installation and depends on how much of the system you actually use. Estimate it with the running cost calculator using the unit's input power and your tariff.
