Introduction
Thinking of installing air conditioning but not sure what it costs? Whether you’re upgrading your home in Sydney or fitting out a new property in Parramatta, understanding the true cost of air conditioning installation helps you avoid surprises and make smarter decisions.
At Eleco Electrical & Data, we specialise in professional air conditioning installation across Greater Sydney. From split systems to full ducted setups, this guide breaks down the prices, options, and key factors so you can choose the right cooling solution for your home or business.
Factors That Affect Air Conditioning Installation Costs
- Type of Air Conditioning System
The kind of aircon system you install has the biggest impact on the price. Here’s a quick comparison:
Split System Air Conditioners
Split systems are one of the most popular options across Sydney homes.
- Installation cost: $600 – $3,500 (unit + install)
- Best for: Single rooms or small areas
- Popular brands: Mitsubishi Electric, Daikin, Fujitsu, Panasonic
Ducted Air Conditioning Systems
A ducted aircon setup cools the whole home through concealed ducts and ceiling vents.
- Installation cost: $5,000 – $15,000+
- Best for: Large homes or commercial spaces
- Includes optional zoning for energy savings
Multi-Head Split Systems
These systems connect multiple indoor units to a single outdoor unit.
- Installation cost: $2,500 – $7,500
- Best for: Homes needing cooling in several rooms
Portable & Window Air Conditioners
These budget-friendly options are plug-and-play but less powerful.
- Installation cost: $0 – $300
- Best for: Renters or temporary cooling
- Air Conditioner Size & Cooling Capacity
Choosing the right aircon size (measured in kilowatts or kW) ensures your system runs efficiently. Undersized units will overwork; oversized ones waste energy.
| Room Size (m²) | Recommended kW | Total Cost (Estimate) |
|---|---|---|
| 10–20 m² | 2.5–3.5 kW | $1,200 – $2,500 |
| 20–40 m² | 3.5–5 kW | $1,500 – $3,500 |
| 40–60 m² | 5–7 kW | $2,500 – $4,500 |
| 60 m²+ | 7–10+ kW | $3,500 – $6,500+ |

- Location-Based Labour Costs
Your suburb can affect installation pricing due to travel time, access, and regional demand. Below are average costs for air conditioning installation in Sydney areas:

- Air Conditioning Campbelltown: $650 – $5,200+

- Site-Specific Installation Challenges
A straightforward back-to-back install is cheaper than a multi-storey, tight-access job with long pipe runs or additional electrical work. Here are extra costs to keep in mind:
- Electrical circuit upgrades: $150 – $1,000
- Roof brackets or mounting stands: $120 – $350
- Long refrigerant piping: $50 – $100 per metre
- Removal of old AC units: $50 – $200

Higher-end brands like Mitsubishi, Fujitsu, or Daikin often cost more upfront but save you more over time thanks to advanced inverter tech and energy ratings.
Tip: Look for units with a high ZERL star rating (Zone Energy Rating Label) for better efficiency in Sydney’s climate.
