Electrical Work Requirements
Some homes may require electrical upgrades before installing a new air conditioning system. Older properties, particularly those built before modern electrical standards, may need circuit upgrades or additional wiring to safely power the system. Licensed electricians are typically involved in this process to ensure compliance with Australian electrical safety regulations.
Mounting and Structural Considerations
The placement of indoor units and outdoor units will also determine the installation cost.
The placement of outdoor units can be on concrete slabs, wall brackets, or ground stands, depending on how the property is laid out. In addition, indoor units must be installed at a certain height and angle for proper airflow and drainage.
Accessibility of Installation Areas
Accessibility can significantly influence installation costs. If technicians must work in tight roof spaces, high walls, or difficult outdoor locations, installation time may increase. For example, installing a split system Melbourne unit in a second-storey bedroom or apartment balcony may require additional labour and safety measures.
Additional Costs to Consider
While the primary cost involves installation labour, homeowners should also consider other potential expenses.
Electrical Isolation Switches
