What Is a Split System Air Conditioner?

A split system consists of two main components:

Indoor unit: Mounted inside the home, it delivers cooled or heated air to the room.
Outdoor unit: Houses the compressor and expels heat from inside the property.

This configuration allows precise temperature control, quieter operation, and energy-efficient performance, making it a popular choice for Eltham homes.

Several elements influence the overall cost of a split system installation:

Unit Size and Capacity
- Larger rooms require units with higher capacity, increasing equipment costs.
Brand and Features
- Units with advanced inverter technology, smart controls, or air purification can cost more.
Installation Complexity
- Pipe runs, wall types, and access to the outdoor unit affect labour costs.
Electrical Requirements
- Older properties may require upgrades to circuits or wiring.
Number of Zones
- Multi-zone systems require additional indoor units and more extensive pipework.
