Check the licence and insurance before you book. Air conditioning work involving refrigerant handling requires a specific licence in Australia, and anyone doing electrical wiring needs an electrical licence too. Ask to see current details and don't be shy about it. A technician who holds proper cover and qualifications won't mind the question, and it protects you if something goes wrong with the installation or repair down the track.

Get a written quote that spells out the scope. A proper quote names the brand and model being installed or serviced, the work included, and what's excluded. A vague verbal estimate is where cost blowouts start. If a figure seems too good against everyone else's, ask what's been left out before you sign anything.

Ask about call-out charges and after-hours rates upfront. Many technicians charge a call-out fee on top of labour, and rates often rise for weekends or after-hours jobs. None of this is unusual, but you want it in writing before the van turns up, not as a surprise on the invoice. Ask whether the quote includes GST, travel, and disposal of any old unit being replaced.

Think about timing before you panic-book. Installations get booked out well ahead of hot weather, so if your system's on its last legs, organise a quote early rather than waiting for a breakdown in the middle of a heatwave. For a genuine emergency, like a complete failure in extreme heat or a unit leaking water into the ceiling, ask directly whether the business offers emergency call-outs, since not all of them do.

Have the details ready and watch for red flags. Before you call, note the make and model if you have one, take photos of the unit or the problem area, and think about access, stairs, roof space, tight courtyards. Be wary of anyone who pressures you to decide on the spot, asks for full payment before work starts, or won't put the job in writing. A tidy, on-time operator who explains the work clearly is usually the safer bet.

Common Questions

: Cost depends on the type of system, whether it's a split system or ducted, the size of the space, and how complicated the installation is, including access and any extra wiring or piping needed. Repairs vary depending on the fault and whether parts need replacing. The only reliable way to know is to get a written quote for your specific job, and compare a couple of them before deciding, so you know exactly what's included.
: Yes, for most of it. Handling refrigerant requires a specific licence under Australian law, and any work involving fixed wiring needs an electrical licence as well. Always check that whoever you're hiring holds the right licence for the job, not just general trade experience. It protects you legally and means the work is more likely to meet Australian standards, which matters for safety and for any warranty claim later.
: Ask what the quote covers, whether it includes GST, travel and disposal of an old unit, and whether there's a call-out charge. Ask who will actually do the work, whether it's the business owner or a subcontractor, and what warranty applies to both parts and labour. Ask about timeframes too, especially around busy periods. A technician who answers clearly and puts it in writing is generally easier to deal with if issues come up.
: Some technicians offer emergency call-outs, but it's a smaller slice of the market than standard repairs and servicing, so check directly rather than assuming. After-hours and weekend rates are often higher, which is standard practice, not a rip-off. If your system fails during extreme heat, say so when you call, as some businesses will try to prioritise genuine emergencies over routine bookings.
: Generally it's the landlord or property manager's responsibility to arrange and pay for repairs to an existing system, especially if it was there when you moved in. Check your lease and contact the agent first rather than booking a technician yourself, unless you've been told to. If you do need to organise it, keep the quote and invoice, since you may need to be reimbursed.
: This comes up with ducted systems needing extra wiring, or installations needing structural work for ceiling or wall access. A good technician will tell you upfront if part of the job falls outside their scope, rather than leaving you to discover it halfway through. Ask during the quote stage whether everything needed is included, or whether you'll need to separately organise an electrician or another tradesperson.
