Key takeaways
- Most aircon installation jobs in Australia land between A$1,500–A$25,000 — known locally as air conditioning installer.
- Refrigerant handling in Australia requires an ARCtick licence from the Australian Refrigeration Council, and the electrical connection must be done by a licensed electrician. Split systems dominate; ducted and multi-head installs are common in larger homes. Energy star ratings guide running costs.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Australia typically run above the national range; smaller towns below it.

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
What size air conditioner do I need?
Sizing is by room area, ceiling height, insulation, window area and sun exposure — a good installer does a load calculation, not a guess. An undersized unit runs constantly and never cools; an oversized one short-cycles and wastes energy. Insist on a sizing rationale in the quote.
What warranty should aircon installation come with?
Expect a manufacturer warranty on the unit (often 5+ years on the compressor if registered) plus an installer's workmanship warranty on the labour and pipework. Poor installation is the main cause of early failures, so the labour warranty matters as much as the unit's.
Does aircon installation include the electrical work?
Not always. A new unit often needs a dedicated circuit and isolator, which may require a licensed electrician. Confirm whether the quote includes the electrical supply, or whether that's a separate cost you'll arrange yourself.
Should I get a split system, multi-split, or ducted?
A single split cools one room cheaply. A multi-split runs several indoor heads off one outdoor unit — good for a few rooms without ductwork. Ducted gives even whole-home comfort but costs most and needs ceiling/roof space. Match the choice to how many rooms you actually cool.
What maintenance does air conditioning need after install?
Clean or replace filters regularly, and have the system serviced roughly annually — coil clean, gas-pressure check and drainage clear. Skipping maintenance cuts efficiency, breeds mould in the drain, and shortens compressor life. Ask about a service plan at install.
Who is legally allowed to install air conditioning?
Handling refrigerant is regulated almost everywhere — installers need the relevant certification (see country notes) and often a separate electrical licence for the power supply. Uncertified refrigerant work is both illegal and a common cause of leaks and voided warranties.
How much does it cost to install air conditioning?
A single-zone split unit for one room is the cheapest entry point; a multi-zone system serving several rooms is a mid-range job; a ducted/central system for a whole home is the priciest. The unit's size (in BTU/kW) and the difficulty of the pipe and cable runs drive cost more than the brand.
What does aircon installation cost in Australia?
A single split runs about $1,500-5,000 installed; multi-head systems $5,000-14,000; ducted whole-home from around $9,000. Long pipe runs, second-storey installs and three-phase power push prices up.
