How much does it cost to install a split system in Australia?

A split system air conditioner installation in Australia costs $600–$3,000+ on top of the unit price, depending on pipe run distance, electrical requirements, and site access. A simple back-to-back installation costs $600–$900, while complex installations with long pipe runs and switchboard upgrades can exceed $3,000.

Why do aircon quotes vary so much?

The four main factors are: pipe run distance (every extra metre costs $60–$120), electrical requirements (a switchboard upgrade adds $2,000–$4,000), the brand and efficiency of the unit quoted, and what's excluded from the headline price (electrical work, trunking, old unit disposal). Always compare quotes on identical scope.

Does a split system need its own circuit?

Yes. Every split system air conditioner in Australia requires a dedicated electrical circuit from the switchboard — this is a requirement under Australian wiring rules. If your switchboard doesn't have a spare slot or needs upgrading, this adds $250–$4,000 to the installation cost.

Is a more expensive aircon unit worth it?

Over a 10-year lifespan, a 5-star energy rated unit typically saves $150–$250 per year in running costs compared to a 3-star unit. That's $1,500–$2,500 in energy savings, which usually exceeds the upfront price premium. Premium units also run quieter and offer longer compressor warranties.

How much does split system installation cost in Australia?

A split system air conditioner installation costs $1,400–$4,500 in Australia depending on unit size (2.5kW–8kW), brand, pipe run distance, and electrical requirements. The unit itself is typically $800–$2,500, with installation labour adding $600–$2,000.

Why is one aircon quote so much more expensive than another?

The most common reasons for large price gaps between AC quotes are: different pipe run distances (adding $50–$80 per extra metre), electrical upgrade requirements (new circuit or switchboard work adds $500–$2,000), brand and efficiency differences (premium brands cost 30–50% more), and whether the quote includes or excludes concrete pads, brackets, and drainage.
