The first few properly hot days of spring have hit, and you've decided this is the year you're finally sorting out the cooling for the whole house. A multi-head split system is a fantastic, flexible solution, but it's a major investment. So, what's the first thing on everyone's mind? The multi-head split system air conditioner prices.

Budgeting for a system like this involves understanding two key costs: the price of the hardware itself, and the separate cost of a complex, professional installation. This guide will break down the typical prices for the units so you know what to expect.

Heads Up: Unit Price vs. Fully Installed Price

This is the most important thing to get clear from the start. The prices in this guide are for the hardware only. That means the single outdoor unit and the multiple indoor "head" units you'll be installing in your rooms.

The cost of installation is a separate, and significant, quote you will get from a licensed installation company. (As a very rough guide, a multi-head installation can range from $2,000 to $5,000+, depending on the complexity).

Multi-Head Split System Prices by Number of Indoor Units

The main factor that determines the price of the hardware is how many indoor "heads" you need. Here are the common price brackets for good quality systems from reputable brands in 2025.

2-Head Systems (For two rooms)

This is a great option for cooling a master bedroom and a main living area, or two bedrooms. It's a big step up in comfort for a smaller home or apartment.

• Price Range (Hardware Only): $2,500 - $4,500

3-Head Systems (A popular family choice)

This is a very popular setup, often used to cool the main living area and two kids' bedrooms, or a master bedroom, study, and living space.

• Price Range (Hardware Only): $3,500 - $6,000

4 or 5-Head Systems (For larger homes)

For larger homes or for those wanting complete climate control in almost every key room, these systems offer a brilliant, ductless solution.

• Price Range (Hardware Only): $5,000 - $8,000+

What Else Affects the Price Tag of the Unit?

• Brand Reputation: Premium, top-tier brands known for their reliability in Australia (like Daikin, Mitsubishi Heavy Industries, etc.) will be at the higher end of the price range.
• Total Outdoor Unit Capacity (kW): A powerful outdoor unit that can run five heads at once will cost more than a smaller one designed for just two.
• Energy Efficiency (Star Rating): Units with higher energy star ratings are often more expensive to buy, but they will save you a fortune on your power bills over the life of the system.

Don't Forget the Separate Installation Cost!

Remember to budget for a professional installation, which is a complex job. By law in Australia, it requires two fully licensed tradespeople: a licensed air conditioning technician (with an ARCtick licence) and a licensed electrician. Get at least three detailed, written quotes before you commit.
