**Air conditioner replacement cost in Brisbane starts from $1,836.51 including GST for a new 2.5 kW split system, supplied and installed back to back on a single storey home, plus $93.50 to remove the old unit.** Bigger systems cost more, up to from $3,783.25 for 8 to 9.5 kW. Seven things decide where your job lands, and we explain each one below.

The quick answer

- A new 2.5 kW split system, supplied and installed, is from $1,836.51 including GST. A 3.5 kW is from $2,036.50 and a 5.0 kW from $2,436.50.

- Removing the old unit is $93.50 including GST.

- A wall bracket is a $104.50 extra. Double storey or highset work adds $275.

- Bought your own unit? Install only is from $1,239.81 including GST.

- Multi head systems are quoted after a site visit. We don’t install ducted systems.

### How much does it cost to replace an air conditioner in Brisbane?

Size is the biggest driver. These are our supplied and installed prices for a single head split system, back to back on a single storey home.

Faze split system replacement prices, including GST, checked 5 October 2026

| New system size | Supplied and installed |
| --- | --- |
| 2.5 kW | Haier $1,836.51, Mitsubishi Heavy Industries $2,053.81, Daikin $2,162.40 |
| 3.5 kW | from $2,036.50 |
| 5.0 kW (dedicated circuit included) | from $2,436.50 |
| 7.1 kW | from $2,836.50 |
| 8 to 9.5 kW | from $3,783.25 |
| Install only, you supply the unit | from $1,239.81 |
| Remove the old unit | $93.50 |

Don’t just match the old unit’s size. If the room never cooled properly, it may have been too small. Our [sizing guide](https://www.fazeelectrical.com.au/what-size-air-conditioner-do-i-need/) shows how to match kW to the room, and the full list is on our [air conditioning pricing list](https://www.fazeelectrical.com.au/air-conditioning-pricing/).

### Seven things that change the replacement price

Every quote starts from the size price above. These seven things move it up or down, and each one is listed on your written quote.

What changes the price, Faze prices including GST, checked 5 October 2026

| Factor | What it means | Price |
| --- | --- | --- |
| 1. Size | The kW the room needs | See the table above |
| 2. Brand | Haier, Mitsubishi Heavy Industries or Daikin | At 2.5 kW, $1,836.51 to $2,162.40 |
| 3. Height | Double storey or highset home | $275 extra |
| 4. Outdoor unit mounting | Wall bracket, or a polyslab on the ground | Bracket $104.50, polyslab $121 |
| 5. Pipe route | Pipe over instead of back to back, or a side exit from the indoor unit | Pipe over from $385, side exit $203.50 |
| 6. Drainage | A condensate pump where water can’t drain by gravity | $484.65 |
| 7. The old unit | Removing it | $93.50 |

 Outdoor units on wall brackets. A bracket is a $104.50 extra on any install.

If you’d like a cost for a first install with no old unit to remove, our [air conditioner installation cost](https://www.fazeelectrical.com.au/air-conditioner-installation-cost/) guide covers it. Standard scope is on the [air conditioner installation Brisbane](https://www.fazeelectrical.com.au/air-conditioner-installation-brisbane/) page.

### Brand and star rating

At 2.5 kW, brand moves the price between $1,836.51 for Haier and $2,162.40 for Daikin, with Mitsubishi Heavy Industries at $2,053.81. We also install a Panasonic or other new unit you’ve bought, from $1,239.81.

Running cost matters too. The Australian Government’s [Energy Rating guide](https://www.energyrating.gov.au/consumer-information/understand-zoned-energy-rating-label) rates air conditioners from 1 to 10 stars, and more stars means more efficient than models of a similar size. It says to choose the size first, then compare stars.

**Our view:** compare star ratings only between units of the same size. A bigger unit uses more power even with the same stars.

### Removing the old air conditioner

Removing the old split system is $93.50 including GST. The gas inside it can’t just be let out. The Australian Government’s [refrigeration and air conditioning page for consumers](https://www.dcceew.gov.au/environment/protection/ozone/rac/consumers) says it’s illegal to release regulated refrigerants into the air, and only licensed technicians can handle them.

 Refrigerant work needs a licensed technician. Our ARCtick licence is L181564.

That’s why removal belongs on the same quote as the new unit, done by the same licensed team.

### One licensed team for the gas and the wiring

A replacement has two licensed parts: the refrigerant and the electrical connection. The Queensland [Electrical Safety Office](https://www.electricalsafety.qld.gov.au/ddiy) says appliances that need to be hard wired must be connected by a licensed electrician.

- Queensland electrical contractor licence 90552, for the circuit and the switchboard connection.

- ARCtick licence L181564, for the refrigerant.

- A 5 year workmanship warranty on every split system installation.

Older switchboards sometimes need work before a new circuit can be added. If yours does, we’ll tell you before we start, and our [switchboard upgrade cost guide](https://www.fazeelectrical.com.au/switchboard-upgrade-cost/) explains what’s involved. [This guide to the two licences](https://www.fazeelectrical.com.au/do-i-need-an-electrician-to-install-air-conditioning/) explains why both matter.

### Should you repair or replace the old system?

Get both prices before you decide. A regas after a leak check is $709.50 including GST for a 2 to 3.5 kW system, against from $1,836.51 for a new 2.5 kW split system.

- Has the system needed other repairs lately?

- Has it ever cooled the room properly?

- What does the repair involve, and is the part available?

Our [air conditioner repair cost guide](https://www.fazeelectrical.com.au/air-conditioner-repair-cost/) covers the repair side, and we do [air conditioning repairs in Brisbane](https://www.fazeelectrical.com.au/air-conditioning-repair-brisbane/) as well as replacements.

### Ducted and multi head systems

Multi head systems run several indoor units from one outdoor unit. We quote them after a site visit, because the pipe runs and head combinations decide the price.

**Ducted systems**

We don’t install or replace ducted air conditioning. We do service and clean ducted systems: a ducted service and coil clean is $621.50 including GST.

### Common questions about air conditioner replacement

#### Is the written quote free?

Yes. The written quote is free, and the quoted price is the invoiced price.

#### What warranty comes with the new system?

Our installation carries a 5 year workmanship warranty. The unit itself carries its maker’s warranty.

#### Do you replace air conditioners in Logan?

Yes. We’re based in Woodridge, and Logan prices and coverage are on our [air conditioning installation in Logan](https://www.fazeelectrical.com.au/) page. All our published prices are on the [Faze Electrical pricing page](https://www.fazeelectrical.com.au/pricing/).

Our advice

Check the room size before you choose the new unit, because size moves the price more than brand does. Then ask for one written quote that lists the new system, the $93.50 removal and any extras such as a $104.50 wall bracket, so you see the full cost before work starts.
