Common Air Conditioning Job Costs
Air Conditioning Services We Cover
TradeRefer's air conditioning hub supports everything from single split system installations to full ducted system replacements and routine maintenance.
Before You Hire an AC Installer
Use these checks to avoid unlicensed refrigerant work, substandard equipment, and hidden installation costs.
Check for an ARC licence
Any tradesperson who handles refrigerants must hold a current Australian Refrigeration Council (ARC) Refrigerant Handling Licence. This is a federal requirement. Ask for the licence number and verify at www.arctick.org before booking.
Get a written quote with full specifications
Your quote should specify the exact brand, model, capacity (kW), energy star rating, warranty period, and installation conditions. Vague quotes allow contractors to substitute lower-quality equipment without your knowledge.
Confirm electrical and gas sub-contractors
Air conditioning installation involves electrical connections (requiring a licensed electrician) and potentially gas connections for ducted heating. Confirm whether your installer manages these in-house or sub-contracts, and that all sub-contractors are appropriately licensed.
Compare brand-agnostic installers
Some technicians are aligned with or incentivised by specific brands. TradeRefer surfaces trade profiles ranked by real community referrals — helping you find independent HVAC technicians who will recommend the right system for your home, not just the brand they stock.

Air Conditioning: Frequently Asked Questions
How much does ducted air conditioning cost to install in Australia?
Ducted reverse-cycle air conditioning typically costs $6,000–$15,000 installed for a standard 3–4 bedroom home, depending on the number of zones, brand, and access difficulty. Split systems cost $800–$3,500 installed per unit.
What size air conditioner do I need for my room?
A rough guide: 1kW per 10m² for standard rooms. A 20m² bedroom needs ~2–2.5kW, a 40m² open plan needs ~4–5kW. A qualified HVAC technician will perform a proper load calculation accounting for insulation, ceiling height, and sun exposure.
How often should air conditioning be serviced?
Residential split systems should be serviced annually — clean filters, check refrigerant, inspect coils and drainage. Ducted systems and commercial units need servicing every 6–12 months depending on usage. Regular servicing extends lifespan and maintains energy efficiency.
What is a reverse-cycle air conditioner?
A reverse-cycle air conditioner provides both cooling in summer and heating in winter using a heat pump. It's the most energy-efficient heating option for most Australian climates, and is 3–5x more efficient than electric resistance heaters.
How long does a split system air conditioner last?
A quality split system air conditioner lasts 10–15 years with annual servicing. Inverter models tend to outlast fixed-speed units. Brands like Daikin, Mitsubishi, and Fujitsu generally have strong reliability records in Australian conditions.
Can I install a split system myself in Australia?
No. Connecting refrigerant lines and electrical wiring requires an ARC-licensed technician and a licensed electrician. DIY installation voids the manufacturer's warranty and is illegal. Only the indoor unit mounting bracket can legally be installed by an unlicensed person.
