What Affects Air Conditioning Costs in Gold Coast

System type

Split systems are cheapest to install. Multi-splits serve multiple rooms from one outdoor unit. Ducted systems are the most expensive but provide whole-home climate control.

Capacity (kW)

A bedroom needs 2.5kW, a living room 5–7kW, and a large open-plan area 7–10kW. Undersizing means the unit works harder and costs more to run.

Installation complexity

Back-to-back installs (indoor unit on the other side of the wall from the outdoor unit) are cheapest. Long pipe runs, multi-storey installs, and roof-mounted outdoor units cost more.

Electrical requirements

Larger units (7kW+) may need a dedicated circuit or switchboard upgrade, adding $200–$800.

Brand

Budget brands (Kelvinator, Hisense) cost 30–40% less than premium brands (Daikin, Mitsubishi Electric) but may not last as long or be as efficient.

Time of year

Installers are busiest in summer and winter. Spring and autumn installs may be cheaper and faster.
