How aircon installation is priced in Australia
Use the same system capacity and model, unit positions, pipe route and electrical scope when comparing quotes. Ask whether brackets, drainage, old-unit removal and making good are included.
Confirm who handles refrigerant, electrical and other regulated work, and check their licence scope with the relevant authorities. Ask how capacity was assessed and whether site inspection could change the price.
Estimate or verified?
Here aircon installation prices on this page are modelled estimates using existing guide assumptions, without a reconciled source dataset. An observed range is published only when its numbers are computed from at least 10 eligible submissions with matching scope, tax and materials treatment. Quotes and paid invoices are kept separate.

Modelled ranges, not observed prices. The spread between cities comes from a published city multiplier applied to the national range — it is an assumption about each market, not a measurement of it.

Questions to ask an air con installer
Most overcharging hides in the scope, not the headline price. These pin down the deal before you commit; for items often charged separately, see Ask about separate charges. If a price changes after you agree, see your rights when a quote changes.
- 1
Is this a fixed quote or an estimate?
A quote is generally a fixed price for the scope described; an estimate is a guess that can change. Ask which one you are getting.
- 2
Can you put the full scope and the final price in writing before any work starts?
A written list gives both parties a scope to check before agreeing to the work.
- 3
If you find extra work on the day, will you stop and price it before doing it?
Agree that any variation is priced and approved before it starts, not added to the invoice afterwards.
- 4
How much deposit do you need, and when is the balance due?
Know what you pay up front and what triggers the final payment before you agree.
- 5
Is GST included in the price you have quoted?
Confirm whether the supplier is GST-registered and whether GST is included. Check the ATO for registration rules.
Three checks that take five minutes
Check the licence
For licensed trades, ask for the licence number and confirm it on your state's fair-trading or licensing site before you book. Requirements depend on the work and location; check the relevant regulator.
Confirm they're insured
Ask what insurance covers this work and check exclusions with the insurer. If an operator can't confirm it, that's a red flag.
Insist on a written quote
A fair quote itemises the scope, names what's excluded, and states whether GST is included. A written record makes the agreed scope easier to check.
Who is allowed to do aircon installation in each state
Licensing is the first thing to check before comparing prices. An unlicensed quote for licensed work is not a quote you can use.
Licensing and permissions guidance
Air conditioning and refrigeration: checked sources
On a small screen, scroll across to see every column.
| Location | Official source | What to check |
|---|---|---|
| All states | Australian Refrigeration Council | Anyone who installs, services, decommissions or otherwise handles fluorocarbon refrigerant in your air conditioner must hold a Refrigerant Handling Licence from the Australian Refrigeration Council; handling fluorocarbon refrigerant without the right licence is a strict liability offence. For a standard single-head split system under 18kW cooling capacity, a Restricted Heat Pump — Split Systems — Installation and Decommissioning licence covers installation and decommissioning; multi-head systems, anything above 18kW, and any service or repair that accesses the refrigerant require the full Refrigeration and Air Conditioning licence. The business quoting you also needs a separate Refrigerant Trading Authorisation, which is what permits a business to buy, store or sell refrigerant — it is not the same thing as the technician's licence. Ask for the licence number on your quote and check it in the ARC's public directory before you book.Official source checked 2026-10-20. Confirm current requirements with the regulator. |
| All states | State and territory electrical regulators | An ARC refrigerant handling licence covers refrigerant work only — it does not authorise electrical work. Connecting your unit to the home's electrical installation, running a new circuit or adding a protective device at the switchboard is electrical installation work, and must be done by someone holding the electrical worker or contractor licence issued by your own state or territory; there is no national electrical licence. A restricted electrical licence held by a refrigeration technician is narrower again: it generally permits testing, repair and maintenance of the equipment, not new installation wiring. So on a split-system installation expect two separate credentials, and expect the electrical compliance certificate your state requires — if an installer can only produce an ARC number, ask who is doing the electrical work and under which licence.Official source checked 2026-10-20. Confirm current requirements with the regulator. |
| QLD | Australian Refrigeration Council | The ARC scheme covers fluorocarbon refrigerants only, so work with an alternative such as a hydrocarbon refrigerant does not require an ARC licence. Queensland is the exception the ARC names: it requires a separate licence for hydrocarbon refrigerant work. If you are quoted a hydrocarbon retrofit or a hydrocarbon system in Queensland, ask which licence the technician holds for that specific refrigerant rather than accepting an ARC number as covering it. The electrical licensing position is unchanged — the refrigerant licence never authorises the electrical connection.Official source checked 2026-10-20. Confirm current requirements with the regulator. |
| Your location | Australian Business Licence and Information Service | Search the exact activity and location to find licensing, regulatory and council requirements. Follow through to the named authority and verify the provider separately. This lookup is not confirmation that a provider is licensed or a job is exempt.Official source checked 2026-10-14. Confirm current requirements with the regulator. |
This is not a complete register of requirements. Where a state-specific source has not been checked, use the government lookup. Qualified trade review is pending; no universal licence exemption is asserted.
Common mistakes
Comparing different equipment and scope
Use the same capacity, model, unit locations, pipe route and electrical work.
Leaving permissions until installation day
Confirm property, strata and applicable approval requirements before booking.
Frequently Asked Questions
How long will installation take?
Ask for a site-specific schedule covering access, electrical work, installation and commissioning. FairCost does not have measured completion times.
Who handles electrical and refrigerant work?
Have the quote identify the responsible providers and verify their licence scope with the relevant authorities.
Can a system be installed in my unit?
Check ownership or strata conditions, placement, drainage and applicable approvals before selecting the system. A price estimate does not establish permission.
