Air conditioning installation in Brisbane in 2026 typically costs $600–$1,200 for a standard split system (supply and install), rising to $5,000–$15,000+ for ducted systems in a full home. With Brisbane's long, humid summers, investing in the right system and a quality installer pays off.
Air conditioning installation in Queensland must be done by a licensed refrigeration and air conditioning mechanic holding a current QBCC licence and an ARC (Australian Refrigeration Council) refrigerant handling licence.

Split System vs. Ducted: Which Should You Choose?
Split Systems
Split systems are the most common choice for individual rooms or open-plan living areas. They're affordable, efficient, and easy to install. For most Brisbane homes without existing ductwork, a well-placed 5–7kW split system will cool a main living area effectively.
Multi-Head Split Systems
Multi-head systems connect multiple indoor units to one outdoor compressor, making them cost-effective for cooling 2–4 rooms without ductwork. They're popular in Brisbane's newer townhouses and apartments.
Ducted Systems
Ducted systems provide whole-home climate control through a central unit and concealed ductwork. They're more expensive upfront but offer the best aesthetics and consistent temperature control. Ideal for new builds or major renovations where ductwork can be installed during construction.
What Affects the Installation Cost?
- Unit size and brand — premium brands (Daikin, Mitsubishi, Fujitsu) cost more but tend to be more reliable.
- Installation complexity — longer pipe runs, concrete penetrations, and high walls add cost.
- Electrical circuit — a new dedicated circuit may be needed ($200–$500 extra via an electrician).
- Slab vs. high set — ducted installation is significantly more complex in slab homes.
- Zoning — adding zone controls to ducted systems costs $500–$2,000 extra.
In Brisbane, an inverter-technology split system with a 5-star energy rating will typically pay back its cost in electricity savings within 4–6 years compared to a budget non-inverter unit. Ask your installer about the annual running cost estimate.
