A bedroom needs 2.5 kW ($1,175–$2,450 in Gold Coast), a living room 5–7 kW ($1,775–$4,400). Oversizing wastes energy; undersizing means the unit runs constantly. Get a proper sizing assessment.
Split vs ducted
Split systems ($1,175–$4,400) cool individual rooms. Ducted systems ($6,850–$13,700) cool the whole house through ceiling vents — more expensive but more discreet and effective for larger Gold Coast homes.
Installation complexity
Back-to-back installs (indoor and outdoor units share a wall) are cheapest. Long pipe runs, multi-storey homes, and restricted access in Gold Coast properties increase labour costs.
Brand & efficiency
Premium brands (Daikin, Mitsubishi Electric) cost 20–40% more than budget brands (Kelvinator, TCL) but offer better efficiency, quieter operation, and longer warranties.
Electrical requirements
Most split systems need a dedicated power circuit. If your Gold Coast switchboard is full or needs upgrading, add $200–$800 for electrical work.
Season & demand
Summer is peak season for Gold Coast aircon installs — expect longer wait times and sometimes higher prices. Book in autumn or winter for the best availability.
