What Is an ARC Licence and Why Does Your Air Con Installer Need One?

What Is an ARC Licence?

An ARC licence, short for Australian Refrigeration Council licence, is a nationally recognised credential required by law for any technician who handles refrigerants in Australia. Also called an ARCtick licence, it is the legal minimum for anyone installing, servicing or decommissioning an air conditioner that contains refrigerant gas. If your installer does not hold one, the work is illegal under federal law, your manufacturer warranty is almost certainly void, and you could be left with a system you cannot legally have serviced.

This article covers what the ARC licence actually is, why the law requires it, how to check your installer's credentials before they set foot on your property, and what happens if you skip that check. By the end, you will know exactly what to ask before booking any air conditioning installation.

Why the ARC Licence Exists: Refrigerants and the Law

The ARC licence exists because the refrigerants inside your air conditioner are classified as synthetic greenhouse gases under Australian federal law. Releasing them carelessly into the atmosphere causes real environmental harm, and the government treats it as a serious offence. The licence scheme is the mechanism that keeps refrigerant handling accountable across the country.

Refrigerants such as R32 and R410A, the two most common gases found in modern residential split systems, are regulated under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989. R32 has a global warming potential roughly 675 times that of carbon dioxide. R410A is even higher at around 2,088 times. Venting either gas deliberately or through negligent handling is a federal offence that can attract significant fines for both the technician and the business they work for.

The Australian Refrigeration Council administers the national permit scheme on behalf of the Australian Government. It issues licences, maintains a public register of authorised technicians and businesses, and can suspend or cancel credentials for non-compliance. The ARCtick logo on a technician's licence card is the visible proof that they have passed the required training and are authorised to work with refrigerant legally.

For readers who want a closer look at how refrigerants work inside an air conditioner and why different gases are used in different systems, our aircon refrigerant explained guide covers the topic in plain English.

Refrigerant Handling Licence vs Refrigerant Trading Authorisation

There are two main types of ARC credentials, and they cover different things. The Refrigerant Handling Licence (RHL) is held by individual technicians. It authorises a person to physically work with refrigerant, including recovering, recharging and transferring gas during an installation or service job. This is the licence you need to see from the person actually doing the work at your home.

The Refrigerant Trading Authorisation (RTA) is a separate, business-level authorisation. It allows a company to purchase and sell refrigerant in bulk. A business can hold an RTA without any of its individual technicians holding an RHL, so the two credentials do not substitute for each other. As a homeowner, the RTA is largely irrelevant to your situation. What matters is that the individual technician arriving at your door holds a current, valid RHL. Always ask to see it before work begins.

What Happens If Your Installer Doesn't Have an ARC Licence?

Using an unlicensed installer to fit your air conditioner exposes you to three serious risks: legal liability under federal law, the loss of your manufacturer warranty, and genuine safety and performance problems caused by improper refrigerant handling. These are not edge-case scenarios. They are predictable outcomes that affect homeowners every year across Australia.

Legal Liability

Handling refrigerant without an ARC Refrigerant Handling Licence is a federal offence under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989. The liability does not stop with the technician. A homeowner who knowingly engages an unlicensed tradesperson can also be implicated, particularly if they were made aware of the requirement and proceeded anyway. Fines for individuals can run into the thousands of dollars.

The safest position is a simple one. If you cannot verify a current RHL before work starts, do not let the work start. The few minutes it takes to check a licence number is a small price compared to the legal exposure of getting it wrong.

Warranty Void

Most major air conditioning brands make licensed installation a condition of the product warranty. Daikin, Mitsubishi Electric and Fujitsu all include this requirement in their warranty terms. That means if an unlicensed technician installs your unit and something goes wrong, the manufacturer is under no obligation to cover the repair or replacement, regardless of whether the fault was caused by the installation.

This matters more as the price of the unit goes up. The Daikin 2.5kW Lite (FTXF25WVMA, $989) is a popular entry-level unit, and losing warranty cover on a $989 purchase is painful enough. The Mitsubishi Electric 2.5kW MSZ-LN25VGV ($1,901) sits at the premium end of the residential market, and at that price point, warranty protection is not something you want to gamble with. To understand what a legitimate, licensed installation should cost on top of the unit price, see our guide to split system installation cost in Australia.

Safety and Performance Risks

Refrigerant handling requires precision. An unlicensed installer may undercharge or overcharge the system, leave connections that leak, or vent refrigerant directly to atmosphere rather than recovering it correctly. Any of these outcomes will reduce the efficiency of your system, potentially void your energy star rating claims, and in the case of a refrigerant leak inside a confined space, create a genuine health hazard.

A system that is running on low refrigerant will work harder to reach your set temperature, driving up your electricity bill and shortening the life of the compressor. These are costs that accumulate quietly over years, long after the unlicensed installer has moved on.

How to Check If Your Installer Holds a Valid ARC Licence

Verifying an installer's ARC licence takes less than five minutes and can be done entirely online before you accept a quote. Given that a quality split system and installation together can easily exceed $2,000, it is one of the most straightforward checks you can do to protect your investment.

Follow these steps before booking any air conditioning installation:

1. Ask for the ARCtick licence number upfront. Request it before accepting a quote, not on the day of installation. Any legitimate technician will provide it without hesitation. If they are reluctant or vague, treat that as a red flag.
2. Visit the ARC public licence register at arctick.org. The register is free to search and publicly accessible. You can search by licence number or by business name to confirm the credential exists.
3. Confirm the licence type is an RHL and that it is current. A Refrigerant Trading Authorisation (RTA) is a business-level credential and does not authorise an individual to handle refrigerant on-site. You need to see a Refrigerant Handling Licence (RHL) that has not expired.
4. Cross-check the licence holder's name against the person doing the work. The licence belongs to an individual, not a company. Confirm that the name on the register matches the technician who will actually be at your property. A business can send a different person on the day, so it pays to ask specifically who is coming.
5. For ducted systems or commercial jobs, check state-based licences too. Ducted installations often involve electrical work that requires a separate electrical contractor licence. Requirements vary by state, so check with your relevant state licensing authority if the job is more complex than a standard wall-mounted split system.

Once you have confirmed your installer's credentials and you are ready to choose a unit, browse our range of split system air conditioners to compare models from Daikin, Mitsubishi Electric, Fujitsu and more, all backed by full manufacturer warranties when installed by a licensed technician.

Frequently Asked Questions About ARC Licences

Is an ARC licence required by law in Australia?

Yes. Handling refrigerant without a current Refrigerant Handling Licence (RHL) issued by the Australian Refrigeration Council is a federal offence under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989. This applies to every state and territory. There are no exemptions for small jobs, residential properties or low-volume refrigerant quantities.

Can I install my own air conditioner without a licence?

No. You can mount the indoor unit bracket and run some preparatory work yourself, but any task that involves connecting or disconnecting refrigerant lines requires a licensed technician. Attempting to handle refrigerant without an RHL is illegal, and any installation completed without one will almost certainly void your manufacturer warranty from day one.

How do I check if my air con installer has an ARC licence?

Ask the installer for their ARCtick licence number before accepting a quote, then verify it on the public register at arctick.org. Search by licence number or business name to confirm the credential is current and is classified as a Refrigerant Handling Licence. The register is free to use and takes less than five minutes to check.

Does an ARC licence cover electrical work too?

No. An ARC Refrigerant Handling Licence only authorises a technician to work with refrigerant. Electrical work associated with an air conditioning installation, such as wiring the indoor unit or installing a dedicated circuit, requires a separate electrical contractor licence. Requirements vary by state, so confirm both credentials before any work begins, particularly for ducted or multi-head systems.

Ready to Buy? Make Sure Your Installation Is Done Right

An ARC licence is a legal requirement under federal law, not an optional credential that only matters for large commercial jobs. It protects the environment from harmful refrigerant emissions, keeps your manufacturer warranty intact and ensures your system is charged and connected correctly from day one. Skipping the licence check is one of the most avoidable and costly mistakes an air conditioning buyer can make.

Choosing a quality unit is the right starting point. The Daikin 3.5kW Lite (FTXF35WVMA, $1,194) is one of the most popular mid-range split systems in Australia for good reason: reliable performance, solid energy ratings and a manufacturer warranty that is worth protecting. But that warranty only holds if a licensed technician does the installation. The unit and the installer are two halves of the same decision.
