Pricing guide
Cost is driven mainly by the unit specification and how much additional piping, refrigerant work and mounting labour are required. Service or inspection jobs typically use fewer materials and less labour than a full supply-and-install replacement, while premium or split‑system installs often need more work. Site conditions, access and any required electrical service upgrades may also increase the overall scope.
Unit type and specification
Premium or split‑system units usually involve higher material spend and more labour than standard mid‑range replacements.
Extent of refrigerant piping
Long runs, extra piping or added insulation increase materials and fitting time compared with simple connections.
Mounting and access complexity
Rooftop, wall or otherwise hard-to-reach installations often require extra labour or structural fixing work.
Electrical service requirements
Like‑for‑like swaps generally need basic electrical connection, while meterboard or circuit upgrades add scope and complexity.
Service-only versus full install
Inspection, commissioning or descaling jobs usually involve lower material costs and shorter labour than full replacement installs.
