Heating & Cooling
Compare local heating & cooling and book online in seconds.
Heating and cooling technicians install, service and repair split systems, ducted reverse cycle, evaporative coolers and gas heaters. In Australia, anyone who handles refrigerant must hold an Australian Refrigeration Council (ARC) licence, shown by the ARCtick mark, and hard-wired units also need a licensed electrician. Correct sizing matters as much as brand: an undersized unit runs flat out and an oversized one cycles inefficiently.
OneBookPlus lets you compare local heating and cooling businesses, check reviews and book installs, repairs or seasonal servicing online. Automatic reminders help you service systems before the summer and winter rushes, and your quotes and invoices stay together, which is useful for warranty claims and energy rebate paperwork.

List your business, freeHow to choose a good HVAC Technician
- Check for an ARC refrigerant handling licence, shown by the ARCtick mark; it is mandatory for anyone installing or regassing air conditioners.
- Confirm who does the electrical work, since hard-wired connections legally require a licensed electrician.
- Ask for a heat load calculation or at least a room-by-room sizing rationale, not a guess.
- Confirm public liability insurance, and ask whether the installers on your job are employees or subcontractors.
- Compare running cost estimates and energy star ratings, not just the installed price.
- Ask about brand accreditation, since manufacturer-accredited installers can often offer longer warranties.
Questions to ask before you book
- What is your ARC licence number, and who does the electrical connection?
- What size unit does my room or house actually need, and how did you calculate it?
- What do the unit and installation warranties cover, and for how long?
- Where will the outdoor unit go, and will it meet noise rules for neighbours?
- What does servicing cost annually, and what does a service include?
What does a hvac technician cost in Australia?
A small split system typically costs $1,600 to $2,800 supplied and installed, larger units $2,500 to $4,500, with back-to-back installs the cheapest. Ducted reverse cycle for a family home runs roughly $8,000 to $16,000 depending on zones. Servicing costs $120 to $300, and repairs vary with the fault and refrigerant type. Long pipe runs, difficult access and switchboard upgrades push prices up, and they vary by region. Confirm quotes include GST and any electrical work.
Frequently asked questions
What licences should an air conditioning installer have?
Two things matter: an ARC refrigerant handling licence for anyone who installs, decants or regasses refrigerant, and a licensed electrician for the hard-wired connection nearly all systems need. Some technicians hold both; otherwise the business should bring in an electrician. Ask for the ARC licence number and look for the ARCtick logo; both are checkable online.
What size air conditioner do I need?
As a rough Australian guide, allow about 0.12 to 0.15 kilowatts of cooling per square metre, so a 20 square metre bedroom suits roughly 2.5 kW and a 40 square metre living area 5 to 6 kW. Ceiling height, insulation, window orientation and climate zone shift this significantly, which is why a proper heat load assessment beats rules of thumb.
How often should I service my air conditioner?
Clean the return air filters yourself every few months, and book a professional service every one to two years for a split system, or annually for ducted. Servicing covers coils, drains, refrigerant checks and electrical connections. Booking in autumn or spring avoids the pre-summer rush, when good technicians across Australia are booked out for weeks.
Is reverse cycle heating cheap to run?
Usually yes. A reverse cycle air conditioner delivers three or more units of heat per unit of electricity, making it among the cheapest heating available in most of Australia, typically well ahead of portable electric heaters and increasingly competitive with gas. Efficiency drops in severe frost, so alpine and cold inland areas should ask about low-temperature performance.
Are there rebates for upgrading heating and cooling?
Several states run energy upgrade schemes that discount efficient reverse cycle systems, particularly when replacing old gas heaters or resistive electric heating, with Victoria's program the most established. Eligibility, approved products and amounts change frequently, so ask installers what currently applies in your state and confirm any discount appears in the written quote.
