HVAC & Air Conditioning Pricing Guide
Split AC, multi-head, and ducted system prices — plus how to size properly so you don't end up cooling a room with twice the capacity you need.
Air conditioning in Australia is dominated by reverse-cycle (heat + cool) inverter systems. Split systems are the entry point; ducted systems cool the whole house from one outdoor unit. Pricing depends on capacity (kW), number of zones, and install complexity more than brand alone.
Sizing matters enormously. An undersized unit runs flat-out and can't reach setpoint. An oversized unit short-cycles, humidifies the room badly, and wastes power. Good installers do a rough heat-load calculation based on floor area, insulation, and glass.
What hvac & air conditioning typically costs
$1,800–$4,500
What's included
Reverse-cycle inverter (2.5–5kW), indoor + outdoor unit, back-to-back install, standard electrical.
When this tier fits
Cooling or heating a single bedroom, living area, or home office.
$5,500–$11,000
What's included
One outdoor unit driving 2–4 indoor heads. Good for townhouses and apartments with no ceiling space.
When this tier fits
Apartment or townhouse with distributed rooms and limited outdoor space.
$9,000–$16,000
What's included
One outdoor unit, indoor fan unit in ceiling, ductwork, 4–6 zones, controller, return air grille.
When this tier fits
Whole-house cooling in a single-storey with ceiling space. Cleanest aesthetic.
$15,000–$28,000+
What's included
Larger unit (14–20kW), more zones, My Air or similar smart controllers, roof insulation upgrade if needed.
When this tier fits
4+ bedroom home, high ceilings, or premium system with zone-per-room control.
Prices are indicative AUD ranges based on typical Australian metropolitan pricing. Actual quotes depend on scope, access, and local market.
What affects the price
Capacity (kW)
Rough rule: 1.5kW per 10–15 sqm. Insulation, glass area, and orientation modify this significantly.
Indoor vs ducted
Ducted costs 2–3x a split but cools the whole house. Better aesthetic, more installation complexity.
Electrical upgrades
Large ducted systems often need a switchboard upgrade, dedicated circuit, and sometimes a 3-phase supply — $1,500–$4,000 extra.
Inverter vs non-inverter
Inverters cost more upfront but run 30–40% cheaper. Effectively standard now — non-inverter is legacy.
Before you book — what to check
Correct sizing
Oversized units short-cycle and fail to dehumidify; undersized units can't hold setpoint. Ask for a heat load calculation, not just a guess by room count.
Star rating matters
Higher energy star rating = lower running cost. Over a 15-year system life, a 6-star unit can save $1,500–$3,000 vs a 3-star — often justifying the price gap.
Zoning on ducted
Zoning (per-room control) costs extra but saves significantly on running costs. Don't skimp here.
Servicing
Filters should be cleaned every 3 months; full service every 12–24 months ($200–$400) to preserve efficiency and warranty.
Body corporate approvals
Apartments and townhouses often need body corporate sign-off on outdoor unit placement. Check before booking install.
