How Much Does Air Conditioning Installation Cost in Perth?

At a broad level, air conditioning installation cost Perth falls into two common categories – split system installation and ducted system installation. The final figure depends on the unit size, home layout, installation complexity, and any required electrical upgrades.

Typical price ranges in Perth:

  • Split system installation cost WA: $750 to $1,800+ for standard back-to-back installs. Difficult access, long pipe runs, or double brick walls can push this higher.
  • Ducted aircon cost Perth: $7,500 to $14,000+ installed, depending on zones, roof space accessibility, duct length, and system capacity.

These ranges help you identify whether a quote is fair or unusually low – which often means key exclusions are hidden in the fine print.

Split System Installation Cost in WA

When homeowners look up an AC installation price breakdown for split systems, they usually focus on the unit price. In reality, the installation is what keeps the system efficient, quiet, and compliant.

A standard wall-mounted split in Perth usually includes:

  • Mounting the indoor unit
  • Running insulated copper pipework and cabling
  • Setting the outdoor unit on a slab or wall bracket
  • Connecting to power and testing operation

Split system labour time: Most standard installs take 2 to 4 hours. Complex installs can take 5+ hours.

Costs increase when:

  • Units are far apart or require long pipe runs
  • Double-brick drilling or tight chase runs are required
  • Switchboard upgrades or new circuits are needed
  • Second-storey mounting or access equipment is required

This is why two “identical” 2.5kW splits can have very different installation costs – the home layout drives the final price more than the unit itself.

Ducted Aircon Cost in Perth

Ducted aircon cost Perth varies more because every home layout is unique. Roof access, ducting paths, zoning design, and ceiling height all change the job cost.

A typical ducted install includes:

  • Indoor fan coil unit installed in the roof space
  • Outdoor condenser unit
  • Duct runs to each room
  • Return air grille with filter
  • Zoning and control panel setup

Ducted system labour time:
Most ducted installs take 1 full day. Complex homes can require 1.5 to 2 days.

Costs increase when:

  • The roof space is tight, hot, or difficult to move through
  • There are many zones or long duct runs
  • Ceiling shapes (raked, high, recessed) require special work
  • Switchboard upgrades or power supply changes are needed

A $9,000 vs $14,000 quote often comes down to zoning complexity, access difficulty, and labour hours – not the brand of the unit.

Key Installation Pricing Factors You Need to Know

Five installation pricing factors have the biggest impact on aircon installation cost Perth:

1. System size and type

Larger systems and multi-head splits cost more to install due to longer fit-off times, more cabling, and more complex testing.

2. Home construction and layout

Double brick drilling, two-storey installs, and tight roof spaces increase labour time. Roof access fees may also apply.

3. Electrical installation and upgrades

Older homes often require new circuits, upgraded breakers, or even switchboard upgrades to safely power modern systems.

4. Smart controls, zoning, and add-ons

Wi-Fi controllers, zoning upgrades, and extra return air points improve comfort but add to upfront costs.

5. Labour hours and accessibility

Longer jobs, difficult access, and multi-trade installs always increase price – even for the same model of aircon.

Hidden Costs to Watch Out For

Homeowners worry most about hidden costs. A transparent installer should explain these items up front:

  • Switchboard upgrades or safety switch installation
  • Additional duct or pipe length beyond standard
  • Second-storey or roof-access equipment
  • Wall repairs after drilling or penetration
  • Removal and disposal of old aircon units

Many “cheap” quotes skip these details – which is why the final bill ends up hundreds of dollars higher.

What’s Included in a Professional AC Installation?

To understand air conditioning installation cost Perth properly, you need to know what a quality install includes.

A proper installation should cover:

  • Site inspection and final position check
  • Safe mounting of indoor and outdoor units
  • Correct pipework, cabling, and drain runs
  • All agreed electrical installation or upgrades
  • Pressure testing and vacuum checks
  • Full performance commissioning
  • User handover and control demonstration
  • Cleanup of all work areas

Installers who rush or skip pressure testing often leave leaks, poor airflow, noise issues, or early system breakdowns.

Compare Quotes with Confidence – Checklist

Use this checklist when comparing quotes for an aircon quote comparison:

  • Is the system type and size listed clearly?
  • Are inclusions and exclusions listed?
  • Are electrical upgrades shown as separate line items?
  • Has the installer inspected your roof space and switchboard?
  • Are labour, disposal, and materials included?
  • Is the workmanship warranty clear and written?
  • How does the installer handle hidden costs if they arise?

Two detailed quotes beat three vague ones every time.

Value vs Price – Why the Cheapest Quote Isn’t Always Best

A higher-quality install saves money long term. A careful installer uses the right materials, allows enough time for testing, and guarantees their work.

When comparing value vs price, consider:

  • Safety and WA compliance
  • How quiet and stable the system will run
  • Energy efficiency and long-term running costs
  • The installer’s track record and after-service support

In Perth’s long hot summers, cutting corners on installation usually costs more than you save upfront.
