To choose the right air conditioning technician in Melbourne, focus on five things: current licences, proof of insurance, a detailed written quote, verifiable references, and a clear workmanship warranty. Only licensed professionals can legally install or service air conditioners in Victoria, and the paperwork you receive afterwards protects both your warranty and your legal position. At Solus Air, we service air conditioners across Melbourne and five other capital cities, and the single most common problem we see is homeowners hiring on price alone, then finding the technician was never licensed to do the work in the first place. That matters more than most people realise: under national refrigerant legislation, unlawfully releasing refrigerant carries penalties of up to $132,000 for an individual, and unlicensed work is where that risk starts.
This guide walks through each check you can make yourself before signing anything. Most of it applies whether or not you ever work with us.
What to look for in a Melbourne air conditioning technician
A qualified technician should tick every one of these boxes. If any are missing, keep looking.
- A current ARCtick Refrigerant Handling Licence for any refrigerant work
- The correct electrical licence, and a plumbing registration if the job involves installation
- Public liability insurance and workers’ compensation cover
- A detailed, itemised written quote with no vague ballpark figures
- Verifiable references and consistent independent reviews
- A written workmanship warranty on top of the manufacturer’s parts warranty
- Compliance certificates provided after the work is done
The sections below explain how to verify each one, and why it matters.
Which licences does an air conditioning technician need in Victoria?
Air conditioning work in Victoria is regulated across three areas: refrigerant, electrical, and plumbing. A single split-system install can touch all three. Always ask to see proof of licensing rather than relying on a business card or an advertisement, and confirm the licence is current and covers your specific job.
Refrigerant handling (ARCtick) licence
Any person who installs, services, or decommissions air conditioning equipment that contains refrigerant must hold a Refrigerant Handling Licence issued by the Australian Refrigeration Council. This is a legal requirement under Australian law. Working on refrigerant without one is an offence under national ozone and synthetic greenhouse gas legislation, and the penalties are steep. Ask the technician for their ARCtick licence number before any refrigerant work begins.
Electrical licence and safety certificate
Connecting an air conditioner to your power supply is electrical work, so the person doing it needs a valid Victorian electrical licence. After the job, a licensed electrical worker must give you a Certificate of Electrical Safety. Air conditioning is classed as non-prescribed electrical work, which means you should receive your certificate within 30 days of completion. If a technician cannot or will not provide one, treat that as a red flag.
Plumbing registration for installations
Ducted and refrigerated air conditioning installations often involve regulated plumbing work, which requires registration with the Building and Plumbing Commission. This body replaced the Victorian Building Authority on 1 July 2025 and now oversees plumber registration across the state. You can check a practitioner’s registration and its currency directly through the Commission before you hire.
How do I confirm a technician’s insurance and safety cover?
A reputable Melbourne air conditioning contractor carries comprehensive insurance and will show you proof without hesitation. Reluctance to produce documents is one of the clearest warning signs there is.
Ask specifically for two things:
- Public liability insurance. This covers damage to your property or injury during the job. Many established HVAC firms carry cover in the range of $10 million to $20 million.
- Workers’ compensation. Anyone carrying out the work on your property should be covered, so you are not exposed if someone is injured.
Beyond insurance, a professional technician follows safety standards as a matter of course: using appropriate protective equipment, recovering and disposing of refrigerant per national codes, and completing all electrical work to standard. These are the quiet signals of a tradesperson who takes the job seriously.
What compliance certificates should I receive?
Compliance certificates carry legal weight, and missing them can void your warranty or create problems when you sell your home.
For a typical installation you should receive:
- A Certificate of Electrical Safety for the electrical connection
- A Plumbing Compliance Certificate where regulated plumbing work was carried out
Keep both on file. They prove the work was done by licensed professionals to the required standard, which is exactly what a manufacturer will ask for if you ever make a warranty claim.
How do I check a technician’s experience and reviews?
Look for a technician or company with solid, demonstrable experience in both residential and commercial air conditioning. Ask how long they have been in business and roughly how many systems they have installed or serviced. A quality contractor will happily provide client references or recent examples of their work.
Two checks are worth doing every time:
- References. Reliable installers should supply past customer contacts so you can confirm punctuality, professionalism, and clean work. Contact one or two if you can.
- Independent reviews. Read reviews on Google and other independent platforms, and look for trends rather than individual comments. A pattern of praise for reliability is a good sign. Recurring complaints, or a wall of one-star reviews with unresolved issues, is a reason to walk away.
A handful of honest, detailed reviews tells you more than a page of glowing testimonials with no specifics.
Why do written quotes matter so much?
Get multiple written quotes before you hire anyone. A reputable technician provides a detailed estimate that breaks down labour, parts, and any call-out or diagnostic fees, and will volunteer their licence number on the quote itself. Vague ballpark figures, pressure to upgrade to a unit you did not ask about, or a hard sell on the most expensive system are all signs to be cautious.
This is where our own approach at Solus Air is simple: the quote is the invoice. We confirm all costs upfront before any work begins, so there are no surprise charges once the job is done. Whoever you choose, look for that same clarity. A quote that itemises each part of the job, and flags any potential extras like additional wiring or permits, is the mark of a contractor who has nothing to hide.
Do not simply choose the cheapest number. A slightly higher quote from a licensed, insured company is often far safer than a rock-bottom price with no guarantees behind it.
What warranties should an air conditioning technician offer?
Choose a technician who stands behind their work with a written workmanship warranty, separate from the manufacturer’s parts warranty. In Melbourne, many contractors offer one to five year guarantees on labour for installations and repairs.
Get the warranty terms in writing and check three things: what exactly is covered, for how long, and what you need to do to keep it valid, such as annual servicing. It is also worth confirming that your equipment manufacturer’s warranty stays intact. Most major brands require a certified technician and proper compliance paperwork to honour a parts warranty, which is one more reason the licences and certificates above matter.
Reputable technician vs red flags: a quick comparison
Use this table as a fast gut check when you are comparing quotes side by side.
| What to check | Reputable technician | Warning sign |
| Licensing | Volunteers ARCtick, electrical, and plumbing details | “Don’t worry, we’re fully qualified” with no proof |
| Insurance | Shows public liability and workers’ comp on request | Hesitates or makes excuses |
| Quote | Itemised, in writing, licence number included | Vague verbal ballpark, pressure to decide fast |
| Certificates | Provides electrical and plumbing compliance certificates | Says they aren’t needed |
| Reviews | Consistent independent feedback, real references | No references, or unresolved one-star complaints |
| Warranty | Written workmanship guarantee, one to five years | Only points to the manufacturer’s warranty |
Checklist for hiring the right air conditioning technician
Before you commit, run through this list:
- Verify licences. Confirm a current ARCtick refrigerant licence plus the relevant electrical and plumbing registrations.
- Check insurance. Ask for proof of public liability and workers’ compensation.
- Compare quotes. Get two or three itemised written estimates and make sure each explains all costs.
- Read reviews and references. Contact past clients and scan independent reviews for consistent patterns.
- Insist on compliance certificates. After the work, collect the Certificate of Electrical Safety and any plumbing compliance certificate.
- Confirm the warranty. Get the workmanship guarantee in writing and check the manufacturer’s warranty stays valid.
By working through these steps, verifying licences and insurance, comparing detailed quotes, checking references, and confirming guarantees, you can hire a qualified, reputable air conditioning technician in Melbourne with confidence.
Frequently asked questions
How do I check if an air conditioning technician is licensed in Victoria?
Ask for their ARCtick refrigerant licence number and their electrical and plumbing registration details, then verify them with the issuing bodies. Plumbing registration can be checked through the Building and Plumbing Commission, and refrigerant licences through the Australian Refrigeration Council.
Do I need a licensed technician to install a split system?
Yes. A split system contains refrigerant and connects to your electrical supply, so it must be installed by someone holding a Refrigerant Handling Licence and a valid electrical licence. Unlicensed installation can void your warranty and breach Victorian regulations.
What certificates should I get after air conditioning installation?
You should receive a Certificate of Electrical Safety for the electrical work, and a Plumbing Compliance Certificate if regulated plumbing was involved. For air conditioning, the electrical certificate should reach you within 30 days of the job being completed.
How long is a workmanship warranty on air conditioning in Melbourne?
Workmanship warranties commonly run from one to five years on labour, separate from the manufacturer’s parts warranty. Always confirm the length and terms in writing before the work starts.
Is it worth choosing the cheapest quote?
Not on its own. The cheapest quote often leaves out compliance work, insurance, or a proper warranty. Compare what each quote actually includes rather than the headline price.
