Air Conditioning Replacement Cost – (Brisbane)

Need to replace an ageing or failing air conditioner? Here’s a fast breakdown so you know what to expect before getting a quote.

When Replacement Beats Repair

Replace if:

• System is 10–12+ years old
• Uses R22 refrigerant
• Major component failure (compressor/PCB) and repair >35–40% of new cost
• Rising power bills + uneven comfort
• Frequent faults in last 1–2 years

Key Cost Drivers

• Correct kW sizing (not just “same as old one”)
• Brand & efficiency level
• Access (roof space, double storey, tight exterior position)
• Electrical compliance (isolator / circuit / board capacity)
• Zoning & smart control (ducted)
• Duct condition (reuse vs replace)

What a Proper Replacement Includes

• Heat/load check (not guesswork)
• Safe decommission & refrigerant recovery
• New pipework / ducts where required
• Pressure test, evacuation & commissioning
• Controller setup + user guidance
• Itemised documentation & warranties

Fast Efficiency Tip

Right-sizing + modern inverter + clean airflow path = lower bills. Each degree lower you set in summer can add roughly 5–10% to running costs—so design matters.
