Living in Brisbane, reliable air conditioning isn’t a luxury; it’s a survival requirement. Whether you are battling the humid January heat or taking the edge off a chilly July morning, the question on every homeowner’s mind is the same: What is the real cost of getting air con installed?
If you have been searching for “air con install” prices online, you have likely found a confusing mix of numbers. Some quotes cover just the unit, others include “standard installation” (which rarely covers everything you need), and many ignore the electrical upgrades required to run the system safely.
At Integrated Trade Services, we believe in transparency. As dual-trade experts qualified in both electrical and air conditioning, we don’t just bolt a unit to the wall; we ensure your home’s power supply can handle it.
Below is your complete guide to air conditioning installation costs in Brisbane for 2025, helping you budget for cooling your home without the guesswork.
At a Glance: Brisbane Air Conditioning Prices
Before we dive into the details, here is a quick snapshot of what you can expect to pay for a quality supply-and-install package in Brisbane.
| System Type | Ideal Application | Estimated Cost (Supply + Install)* |
| Split System (2.5kW) | Small Bedroom / Office | $1,700 – $2,300 |
| Split System (7.1kW) | Living Room / Open Plan | $2,600 – $3,500 |

Split System Installation Cost: What Are You Paying For?
Split systems are the most popular choice for Brisbane homeowners looking to cool specific rooms. They are efficient, relatively quick to install, and cost-effective.
The “Back-to-Back” Standard
You will often see low advertised prices for a “back-to-back” install. This refers to the simplest installation scenario:
- The indoor unit is mounted on an external wall.
- The outdoor compressor sits directly behind it on the ground (or a bracket).
- Piping runs are minimal (usually under 3 metres).
Cost for Install Labour Only: $600 – $900 (excluding the unit).
Cost for Supply & Install: $1,700 – $3,500 (depending on unit size).
Complex Installs
If your indoor unit needs to be on an internal wall, or if the outdoor unit needs to be mounted on a roof or down a hallway, costs will rise. This requires extra copper piping, interconnect cables, and labour time to run drains properly.
Key Consideration: Never choose a location just because it’s cheaper to install. Poor positioning leads to poor airflow and higher energy bills.
Ducted Air Conditioning Prices: The Whole-Home Solution
For complete climate control, ducted air conditioning is the gold standard. It allows you to cool the entire house or specific “zones” (e.g., turning off bedrooms during the day).
Factors Influencing Ducted Costs
- Size of the Unit: A 10kW unit for a small home costs significantly less than a 20kW unit for a two-storey property.
- Zoning: A standard system might have 2 zones (Day/Night). Advanced systems like MyAir allow you to control the temperature in every individual room from your phone, which adds to the initial investment but saves electricity long-term.
- Roof Space: Tight roof cavities require more labour to run flexible ducting.
Estimated Investment:
- Small Home (Single Storey): $8,500 – $11,000
- Medium/Large Home: $12,000 – $18,000+
The “Hidden” Costs: Why You Need an Electrician andan Installer
This is the biggest pain point for Brisbane homeowners. You hire an air con installer, they arrive to fit the unit, and then stop work because your switchboard is too old or your mains cable isn’t thick enough to handle the power load.
Suddenly, you have to scramble to find a separate electrician, pay a second call-out fee, and wait days for the job to be finished.
Common Electrical Surprises
- Switchboard Upgrades: Modern air cons require safety switches (RCBOs). If you have old ceramic fuses, you may need a board upgrade. (Approx. $800 – $1,500)
- Mains Upgrade: If your home’s main power supply is outdated, adding a large ducted system might trip your power constantly. Upgrading the mains cable is a significant but necessary safety task.
- Dedicated Circuits: Every air conditioner needs its own circuit. It cannot just be plugged into a power point.
The Integrated Advantage
This is where Integrated Trade Services stands apart. Because we are experts in both electrical and air conditioning, we handle the entire project in-house.
- One Quote: We assess your electrical capacity during the air con quote.
- One Team: No waiting for a subcontractor sparky to turn up.
- One Warranty: If there is a power issue or a cooling issue, you only have one number to call.
Expert Tip: If you are renovating, ask us to install the electrical rough-in for your air con before the plasterboard goes up. It saves time and money on patching and painting later.
Split System vs. Ducted: Which is Right for You?
Unsure which path to take? Here is how they stack up.
Choose a Split System If:
- You only need to cool one or two specific rooms (e.g., master bedroom and lounge).
- You have a limited budget.
- You live in an apartment with limited ceiling space.
Choose Ducted Air Conditioning If:
- You want seamless aesthetics (only subtle vents are visible).
- You want to add value to your property (ducted is a major selling point in Brisbane).
- You have a large family and need to cool multiple rooms simultaneously.

Frequently Asked Questions
1. Do you take away the old unit?
Yes. If we are replacing an existing system, we can remove and environmentally dispose of the old unit, including reclaiming the refrigerant gas so it doesn’t harm the ozone layer. Just let us know during the quote so we can include this service.
2. Are there hidden electrical costs?
With some installers, yes. With Integrated Trade Services, no. Because we are qualified electricians, we check your switchboard and power supply before we quote. If you need a switchboard upgrade to handle the new AC, we will tell you upfront, not hit you with a surprise bill on installation day.
3. How long does installation take?
- Split Systems: Usually 3–5 hours per unit.
- Ducted Systems: Typically 1 full day for a standard single-storey home, or 2 days for complex/large installations.
4. Can I buy my own unit and just pay you to install it?
While we can provide “install-only” services, we strongly recommend a “supply and install” package. When we supply the unit, we can guarantee the warranty on both the equipment and the workmanship. If you buy a unit online that turns out to be faulty, you may be liable for the labour costs to remove and replace it.
5. Can I place the outdoor unit anywhere I want?
Not exactly. While we try to accommodate your aesthetic preference, placement is governed by two main factors:
- Efficiency: Units need “breathing room” to expel heat. Cramming them into a tight corner will drive up your power bill and kill the unit faster.
- Brisbane Noise Regulations: The Brisbane City Council restricts air conditioner noise to no more than 5dB(A) above background noise between 7am–10pm, and 3dB(A) at night. We carefully select locations (or recommend acoustic barriers) to ensure you don’t get a noise complaint from your neighbours.
6. Why is my quote higher than the “From $699” price I saw online?
Those “bargain” prices are often marketing bait. They typically cover a small 2.5kW unit (supply only) or a “back-to-back” install in a perfect new-build home with zero electrical complications. Our quotes are “turn-key.” They include the unit, the copper piping, the electrical circuit, the wall brackets, the labour, and the GST. When you see a price from us, that is the price you pay to have a working, cooling system on your wall—no asterisks attached.
