How much does air conditioning installation cost

If you’re planning to install an air conditioner at home, it’s normal to wonder how much you’ll end up spending. The truth is that prices can vary a lot. Based on recent numbers from real homeowners and tradies, a complete install (unit plus labor) usually ranges somewhere between $1,380 and $7,144 in Australia. That’s a widespread, but each home is different. A small bedroom split system might cost far less than a large ducted setup in a double-story home. Knowing these ranges gives you a better idea of what to expect, so you don’t feel lost during the quoting stage.

In this full guide, you’ll see what affects your aircon installation cost, what real people have paid, how to avoid common hidden fees, and how to choose the right tradie for the job. 

What Drives the Cost of Installing Air Conditioning?

Several factors influence your final price, and understanding them helps you budget with confidence. Here’s a simple, clear breakdown of the biggest cost drivers.

1. Type of Air Conditioning System

The type of system you choose plays a major role in the final air conditioner cost. A basic split system is much cheaper to buy and install than a full ducted setup. Some systems need more parts, longer installation times, or extra support structures. Each of those adds to the overall cost.

2. Capacity and Size of the Unit

Your installer will assess room size, layout, insulation, and light exposure. Larger areas need higher-capacity units, which cost more. Running an undersized system makes it work harder and wastes electricity, so sizing it right matters.

3. Labour Rates for Licensed Tradies

Labor is one of the biggest parts of any AC install. Many tradies charge hourly rates between $65 and $90 per hour, depending on the job and region. Installers may also charge call-out fees, travel fees, or fixed pricing for standard installations.

4. Wiring or Switchboard Upgrades

If your home has an older switchboard, the electrician might need to upgrade it before installation. This adds to the total cost but keeps your home safe and compliant with current electrical standards.

5. Installation Complexity

Some homes are simple to work with. Others have long pipe runs, tight roof spaces, double brick walls, or tricky mounting spots. These situations take more time and sometimes require special equipment. All of this increases installation difficulty and cost.

6. Local Factors

Costs change from one place to another. Big cities often have higher rates. Remote areas sometimes need extra travel fees. Even the climate can play a role, because hotter regions need stronger units.

7. Season and Demand

Summer is always the busiest season for AC installers. Demand goes up and available booking slots go down, which can lead to higher pricing and longer wait times. Booking in cooler months can save you money and stress.

8. Removal of Old Unit (If Needed)

If you are replacing an existing AC, the AC replacement price goes up because of:

• disposal fees

• removal labor

• possible wall repair

This usually costs $150–$300 extra.

Real Quotes and Examples from Australian Homeowners

Here are some real-world numbers from around Australia. These give you a better sense of actual pricing rather than just estimates.

• Many Airtasker users report paying $200 to $800 for installation only when they already own the unit.

• In Queensland, split system labor is often $531 to $757 for standard installs.

• Sydney tradies can charge $80 to $150 per hour, depending on experience.

• CHOICE reports that basic split system installs often start at $600 to $800+ for labor alone.

Homeowner stories:

• A 2.5 kW back-to-back split install was quoted at $1,100–$1,400, including labor.

• A 6 kW Mitsubishi split system supplied and installed was $3,000, which included six hours of labor.

These examples show that the AC installation price can shift based on the distance between units, the brand of the system, and how easy it is for the tradie to access the installation area.

Extra Costs That May Be Added to Your Quote

Many people forget about these items until they show up on the invoice. Knowing them early helps you plan and avoid surprises.

1. Removing Your Old AC

If you’re upgrading, most tradies charge a small fee to disconnect and dispose of your old unit safely. This usually isn’t included in the base price.

2. Wall Brackets or Support Platforms

Outdoor units sometimes require wall brackets or a concrete support pad. Both add to your AC Install Cost, but they help keep the unit stable and protected.

3. Extra Piping or Cabling

When the indoor and outdoor units are far apart, you’ll need longer copper piping, more insulation, and more labor time. This is a common reason simple installs end up costing more.

4. Switchboard or Electrical Work

If your switchboard is older or cannot take the load of a new AC, an upgrade becomes necessary. This is one of the most overlooked extra costs.

5. Hard-to-Reach Install Areas

Installers may charge more for tight spaces, roof mounts, multi-level buildings, or locations that need special tools or safety setups.

6. Smart Controllers or Zone Features

Smart Wi-Fi controllers, zoning features, or new thermostats add to the cost of fitting air conditioning, especially if extra wiring or programming is needed.

How to Save Money on Your AC Installation?

Here are simple ways to keep your installation cost under control without cutting corners.

• Get at least three quotes: Prices can vary a lot, and comparing quotes helps you see which tradie offers fair value.

• Book during cooler months: Off-season installation can save you money because tradies aren’t as busy.

• Keep your installation simple: Shorter pipe runs, easy access, and a clear installation plan keep labor costs down.

• Ask for bundled pricing: If you need two units installed or want some electrical work done, ask for a combined quote. Installers often reduce rates when jobs are grouped.

• Check for rebates: Some councils or states offer rebates for energy-efficient units. Ask your installer if your system qualifies.

• Maintain your AC: A well-maintained unit runs better, uses less energy, and lasts longer. Clean the filter often and get regular servicing.

These simple habits can save you money now and in the long run.

What to Look for When Choosing a Tradie?

Picking the right installer is just as important as picking the right AC unit. If you want a smooth and safe experience, here’s what to look for when installing an air conditioning unit.

1. Proper Licensing

Only licensed refrigeration and air conditioning technicians can legally handle gas and refrigerant. Always ask for proof and licensed tradies.

2. Insurance

A good installer carries insurance to protect your property and their work. Never hire someone who cannot show you their insurance details.

3. Detailed Written Quotes

A clear quote lists labor costs, unit costs, materials, disposal fees, and extra services. This keeps things transparent and avoids misunderstandings.

4. Warranty and Workmanship Guarantee

Skilled tradies offer warranties for both the system and their installation work. This helps protect your investment.

5. Reviews and Past Work

Check past customer ratings, photos, and comments. This gives you a realistic idea of the tradie’s skill, speed, and reliability.

6. Safe Installation Practices

Ask how the unit will be mounted, supported, tested, and sealed. A good installer will walk you through the entire process and answer your questions clearly.

FAQs

1. How much does a split system air conditioner cost to install?

Installing a split system air conditioner usually costs anywhere between $600 and $2,000, but the final amount depends on how simple or complicated the job is.

For example, if the indoor and outdoor units sit back-to-back on the same wall, the installer can finish quickly, so the cost stays on the lower end.

2. What is the average aircon install price in Australia?

When you look across all types of systems, split, ducted, window, and cassette, the average price in Australia falls between $600 and $5,500.

The wide range comes from the big difference in labor involved. A simple bedroom split system sits at the low end, but a large ducted system covering an entire home requires major installation work, roof access, ducting, and electrical upgrades, which pushes the price up.

3. How much are AC fitting charges for a standard home?

For most Australian homes, AC fitting charges for a single-room split system typically sit between $600 and $1,200.

However, the price increases if the installer has to run pipes over long distances, deal with older walls, install new electrical circuits, or work on higher levels of the home. 

4. What is the AC replacement price if I remove an old unit?

If you’re replacing an old air conditioner with a new one, the replacement price generally lands between $1,300 and $3,500.

This cost includes removing the old unit, disposing of it correctly, preparing the area for the new installation, and fitting your new system.

5. What is the new AC cost, including installation?

The new AC cost, including installation, depends on the type of system you choose.
For a standard split system, the total usually falls between $1,300 and $5,200, including both the unit and the installation work.
