How much does air conditioning installation cost in Perth?
Your price will depend on the system and the work needed to fit it. A longer pipe run costs more. Difficult access or a new electrical circuit can also add to the price. Send us the room details and any useful photos. We’ll tell you if we can quote from those or need to visit.
What drives the price
- System type: wall-mounted split systems are the cheapest; multi-head and ducted reverse-cycle cost more.
- Capacity (kW): sized to the room or home; bigger spaces need more output.
- Install difficulty: pipe run length, wall type, roof access, and whether the switchboard needs an upgrade all affect labour.
- Electrical work: some installs need a dedicated circuit or a switchboard upgrade to run safely.
Why we quote on site
Online ballpark figures are a starting point, not a price. Because every home’s layout, power supply, and access are different, an accurate number comes from a quick assessment. The written quote should identify the selected system, installation scope, electrical work, access assumptions and exclusions before booking.
Our Perth air-conditioning installation guide explains the complete planning and installation process, including the details a written quote should make clear.
