What Does an Air Conditioner Split System Installation Cost in Australia?

If you’re wondering how much it costs to install air conditioning, the answer can vary depending on factors such as unit size, brand, installation complexity, your home and the type of system you want to install. On average, the cost to install a split system air conditioner in Australia typically ranges from $1,400–$3,000, while premium systems and more complex installations can cost more..

Split air conditioner installation costs usually fall under labour-only installation or supply-and-install packages:

Labour Only (Installation Without Supply)

For homeowners who have already purchased a unit, the cost to install a split system air conditioner (labour only) can start from around $600 for a straightforward installation, with more complex jobs costing more.. Current Australian cost guides indicate installation can increase depending on the complexity of the work, the installer and additional requirements.

This covers the physical installation, but additional costs may apply for electrical work or extended pipe runs.

Supply and Installation Combined

For a full split system aircon installation cost (unit + installation), most homeowners can expect to pay around around $1,400–$3,000 for a professional straightforward installation.

Keep in mind that aircon installation cost can vary by location, installer, access and job complexity.

Rather than choosing a system based solely on its purchase price, consider the total cost of ownership, including installation, energy use, maintenance and the expected lifespan of the system.

What Affects the Cost of Installing a Split System?

Several factors can influence the  cost of split system installation including:

Unit Size and Capacity

Larger units cost more to purchase and install. They require heavier equipment, larger pipework and more labour.

To find the right size for your space, see the Air Conditioner Room Size Guide.

Installation Complexity

The more complex the job, the higher the air conditioning split system installation cost. Factors include:

• Longer pipe runs between indoor and outdoor units

• Additional electrical work

• Multi-storey homes

• Difficult wall or ceiling access

For example, a standard back-to-back installation in a single-storey home will sit at the lower end of the split system air conditioner installation cost range. However, a multi-storey home that requires long pipe runs, electrical upgrades and has difficult access can significantly increase installation costs.

Electrical Work

Some homes require additional electrical upgrades, which can increase the AC split system installation cost, such as:

• Installing a dedicated circuit

• Upgrading the switchboard (common in older homes)

• Other electrical modifications required to safely connect the system

Drainage

Split systems produce condensation that must be drained away from the indoor unit.

• Standard installations use gravity drainage

• More complex setups may require pumps, increasing the cost to install split system units

Brand and Model

The system you choose directly affects the cost of aircon installation. Premium systems with advanced inverter technology and smart features typically have a higher upfront cost, but they often deliver lower running costs and better long-term value.

For example, GENERAL’s (formerly Fujitsu General) residential range offers high-quality inverter systems designed for Australian conditions. Choosing a trusted brand also ensures access to reliable installers and ongoing support.

What Should a Split System Installation Quote Include?

When comparing quotes for split air con installation cost, make sure you understand what’s included. A typical cost for aircon installation should cover:

• Unit supply (brand, model, capacity)

• Labour for indoor and outdoor unit installation

• Pipe run length and insulation

• Condensate drainage setup

• Electrical connection and circuit work

• Wall penetration sealing or patching

• System commissioning and test run

• Removal of old unit (if applicable)

Understanding these inclusions helps you compare the real cost of installing split system air conditioner options.

Hidden Costs to Watch For

Not all quotes include every cost upfront. When comparing a split system air conditioner installation cost, watch for additional charges such as:

• Electrical switchboard upgrades

• Extra pipe run beyond standard allowance

• Wall or ceiling repairs after installation

• Removal and disposal of old systems

Clarifying these items early can help you avoid unexpected costs.

Is a More Expensive Split System Worth It?

It’s a fair question, especially when comparing the average cost to install a split system.

While a lower upfront cost may seem appealing, it’s important to consider how often you’ll use the system. A higher-quality unit with better efficiency and performance can reduce your ongoing expenses over time, making it a more cost-effective choice in the long run.

Higher-quality systems often provide:

• Better energy efficiency

• Lower split system electricity consumption

• More reliable performance over time

• Advanced features like inverter control and smart connectivity

For example, GENERAL’s Lifestyle Next Range is designed to balance performance and efficiency, helping offset the initial split system installation cost through lower operating expenses over time.
