Air Conditioning Installation Adelaide — Price Guide

All prices include GST and are pre-rebate estimates — your quote depends on site conditions, brand and complexity.

System type	Capacity	Typical installed price	REPS rebate
Small split	2–3 kW	$1,200–$2,500	$300–$500
Medium split	3.5–5 kW	$1,800–$3,500	$500–$800
Large split	7 kW+	$2,500–$4,500	$800+
Multi-head split	2–3 heads	$4,200–$7,500+	Varies
Ducted (small)	5–7 kW	$5,000–$8,000	$1,000+
Ducted (large)	8–14 kW	$7,000–$14,000+	$1,000–$1,300+

Adelaide installs typically run about 10–15% above the eastern capitals because the licensed-technician pool is smaller.

When comparing quotes, make sure each one covers the same scope. A complete split-system install includes:

• Indoor and outdoor units
• Refrigerant copper pipework
• A dedicated electrical circuit with RCD protection
• Wall penetration and sealing
• Condensate drainage
• Outdoor unit mounting (pad or bracket)
• R32 refrigerant charging, leak testing and commissioning
• Pipe and cable capping for a tidy finish

If any of these are listed as “extras”, ask why before comparing on price.

• Wall construction. Bluestone and sandstone walls (common in Norwood, Unley and Prospect) are 300–400 mm thick; core drilling adds about $150–$300, and long pipe runs add cost per metre. Modern homes in newer suburbs are simpler and cheaper.
• Switchboard capacity. Each split needs a dedicated circuit; a full board upgrade can add $1,500–$2,800.
• Brand and model tier. The gap between an entry model and a premium one is roughly $500–$1,500 per unit.
• Timing. September–November is peak demand and January heatwaves bring 4–6 week waits. Booking April–August usually means better availability and pricing.

Factor	Split system	Ducted system
Upfront cost	$1,200–$4,500 per unit	$5,000–$18,700+

REPS rebate	$300–$800	$1,000–$1,300+

The REPS rebate is applied as a direct discount on your quote — you don't pay full price and claim it back. Worked examples:

• Bedroom split (2.5 kW): $2,400 installed − $400 REPS = $2,000.
• Living-area split (5.0 kW): $3,100 installed − $600 REPS = $2,500.
• Whole-home ducted (12 kW): $12,500 installed − $1,100 REPS = $11,400.
