How to choose an air conditioning installer in Australia

Short answer

Check the licence first — heating & cooling must be licensed in every state. Then check that the business is who it says it is: of the 1,585 Australian heating & cooling in this directory, only 14.8% publish an ABN you can confirm, and 6.3% list a phone number that contradicts the one on their own website.

Heating & Cooling handle split systems, ducted heating and cooling, evaporative coolers, servicing and repairs. This is what to check before you let one into your house, and what the evidence says about the trade as a whole.

Heating & Cooling must be licensed

Anyone handling refrigerant needs an ARC licence from the Australian Refrigeration Council — a national scheme you can check yourself, which is unusually straightforward for an Australian trade. Installing a system also involves electrical work, which requires a separate electrical licence.

There is no national licence register in Australia — each state and territory runs its own. The regulator for your state is listed at the bottom of this guide, and checking a number takes about a minute.

What goes wrong with heating & cooling

  • Refrigerant handled by someone without an ARC licence
  • The electrical side done by whoever was on site rather than a licensed electrician
  • Undersized units sold because the room was never measured

What to ask before the work starts

  1. What is your ARC licence number?
  2. Who is doing the electrical connection, and are they licensed?
  3. How did you size this unit for the room?

A air conditioning installer who answers all three of those without hesitating is telling you something useful. One who is vague about a licence number is telling you something too.

The median matters more than the average

The median air conditioning installer in this directory has 33 Google reviews. That is the number to hold in your head when you see a perfect five-star rating: five stars from four reviews and 4.6 from three hundred are not comparable, and the second is almost always the safer hire.

It is also why the ranking here weights review volume more heavily than review score. A business cannot buy its position, and a handful of glowing reviews does not move it far.

Where the heating & cooling are

Melbourne (151), Sydney (122), Brisbane (110), Perth (76), Newcastle (51), Adelaide (44). A shortlist for your own area is more useful than a national ranking — the best air conditioning installer in the country is no help if they are four states away.

Where to check a licence, by state

There is no national register. Search the licence number with the regulator for the state where the work is happening.

Search the licence number the business gives you on the regulator for the state the work is happening in.
