Air Conditioning Cost

With summer right around the corner, there’s no better time than now to invest in a brand-new air conditioner. However, you might be wondering just how much it might cost to get it installed.

Installation costs depend on everything from the air conditioner’s size to its style, capacity, brand, and technology. While it’s often difficult to give an exact figure, we will provide you with an industry average for some of the most popular types of air conditioning being installed in Melbourne in 2026.

From average costs to rebates, we’ll cover everything you need to know.

Please note: all costs, prices and figures in this article are estimates and should only be considered as general information. Prices may vary depending on location, brand, provider, and various other factors.

Average Installation Costs

In Melbourne and regional Victoria, the cost of an air conditioning installation can range anywhere from $1,250 to upwards of $14,000. When we talk about the costs associated with the process, there are two key aspects: the price of the air conditioning system, and the cost of installation/labour.

Here’s a quick guide.

Cost of the System

Air conditioning system prices vary considerably depending on their style. A 2.5/3 kW split system from brands like Daikin, Fujitsu, Mitsubishi, or Panasonic may have a retail price somewhere between $400-$1,200.

A Braemer ducted system, on the other hand, will have an average initial cost upwards of $2,000-$3,000. Similarly, Daikin and Panasonic ducted systems may come at a price upwards of $4,000.

The cost of the system is the first half of the final installation price. In order to find the best deal, it’s worth shopping around, doing a little research, and comparing prices from brand to brand. Of course, you can always check out the brands we prefer right here at ACSM Air.

Cost of Installation

The second half of the story is the cost associated with the installation itself. In this case, the final price can depend on:

  • The size of the system
  • The number of wall units
  • The type of air conditioner
  • The scope of the installation
  • The cost of parts and labour

The only way to determine the likely cost of an installation is to get a quote from your HVAC company. It is also important to note that the final price can be reduced and offset with rebates currently available in the State of Victoria; we will cover these in more detail below.

Average Cost by Air Conditioning Type (2026)

According to recent estimates from What’s The Damage, the average total installation cost for different types of air conditioning is as follows:

  • Single reverse-cycle split: bedroom or study: $1,500–$2,600
  • Large reverse-cycle split: living area: $2,600–$4,200
  • Multi-split system: 2–4 rooms, one outdoor unit: $3,800–$8,500
  • Ducted reverse-cycle: whole home, 3–4 bedrooms: $8,000–$15,000
  • Evaporative cooling to reverse-cycle upgrade: $10,000–$16,000

Are There Any Rebates Available?

Concerned that the installation might be out of your budget? The great news is that there are rebates available in the State of Victoria. Here’s a quick guide to what they are, how they work, and who’s eligible:

The following details and figures can also be found on the Energy Victoria website.

Who Is Eligible?

The Victorian Energy Upgrades program is available to:

  • All Victorian households and businesses
  • Private rental properties

Landlords and tenants should work together when planning an upgrade.

What Can You Install?

The upgrade must be an approved, high-efficiency reverse cycle air conditioner that provides heating and cooling.

Eligible systems include ducted and non-ducted models.

The product must:

  • Be approved under the Victorian Energy Upgrades program
