Air Conditioning Installation Cost Sydney 2026 — Split Systems, Ducted AC and What Sydney Homeowners Pay

Air Conditioning Installation Cost in Sydney 2026

Sydney's humid subtropical climate makes air conditioning essential for most households. Split system reverse-cycle units dominate the Sydney residential market. Installation costs are at the premium end nationally due to tight trades capacity and high metro labour rates. This guide covers air conditioning installation costs in Sydney in 2026.

Sydney Split System Prices

• Single split system (2.5-3.5kW, bedroom): $800-$1,400 installed
• Standard split system (5-7kW, living area): $1,200-$2,200 installed
• Large split system (8-9kW): $1,800-$3,000 installed
• Labour: $80-$130/hr for ARCtick-licensed refrigeration and electrical tradespeople in Sydney

Sydney Ducted Reverse-Cycle Costs

• Small ducted (3-4 zones, townhouse): $7,000-$12,000 installed
• Standard ducted (4-6 zones, 3-4 bed home): $10,000-$18,000 installed
• Large ducted (6-8+ zones): $16,000-$30,000+ installed

Sydney-Specific Considerations

• Coastal homes (Eastern Suburbs, Northern Beaches, Sutherland Shire): Specify marine-grade corrosion-resistant outdoor units — salt air corrodes standard units rapidly
• NSW Energy Savings Scheme (ESS): ESS-accredited installers offer rebate-subsidised pricing on high-efficiency reverse-cycle systems; ask your installer whether they hold ESS accreditation
• Multi-head split systems are popular in Sydney apartments where outdoor unit placement is shared or constrained by strata by-laws

Popular Sydney AC Brands

• Daikin, Mitsubishi Heavy Industries, Fujitsu, Panasonic, and LG lead the Sydney market; Daikin has the strongest service network across the metro area
