Air Conditioning Installation Price Guide 2025

Thinking of Buying A New Air Conditioner In 2025?

We know how crazy Melbourne's weather can be. It can be hot and humid one minute and freezing cold the next. That’s why you need an air conditioner that can keep up. At 1st Call Electrical, we are highly trained and skilled in installing a wide range of air conditioners throughout Melbourne.

But how much does it all cost? The right answer depends on a variety of factors, including type of system, the size of your home, installation complexity and additional electrical work.

Our electricians have put together this guide to help you break down the costs associated with installing your new air conditioner.

How Much Does An Air Conditioner Cost?

The total cost of installing your new air conditioning system depends on what type and brand you choose. Generally, the cost increases with each system as they progressively get more complicated to install.

At 1st Call Electrical, we proudly install the following air conditioning systems:

Split System Air Conditioners

Split system air conditioners remain a popular choice for all kinds of homes across Melbourne and Australia. However, determining the average cost of installation can be tricky. Our technicians recommend using the size of your room as a guideline to estimate the price.

On average, homeowners can expect to pay anywhere between $600 and $750 to install a split system air conditioner.

Ducted Air Conditioning Systems

Depending on the size of your home, installing a ducted air conditioning system can cost anywhere between $6,000 and $10,000. Investing in a ducted air conditioning system provides discreet, centralised climate control with the main unit often hidden in the roof. Air is then distributed evenly throughout your home or office. It’s an excellent choice for larger homes.

Cassette Air Conditioners

Cassette air conditioners are another efficient cooling solution, often preferred in spaces like offices, retail spaces and open-plan residential areas like kitchens. Since cassette air conditioners are installed in the ceiling, our specialists have to take extra care when installing them and may need extra equipment to get the job done safely.

What Factors Can Affect The Price of Your Aircon Installation?

Your Home’s Layout

The layout and style of your home will impact the accessibility of the installation. If you own a multi-storey home or a large home, the time and cost of the installation will be higher than if we were installing an AC unit into a studio apartment and we will need less specialised equipment to complete.

Size of the Unit

Whilst most split system air conditioners are straightforward to install, other makes and models are more complicated. Ducted air conditioners and cassette units are bigger than split system units and require additional ductwork, so they cost more to install.

Brands

At 1st Call Electrical, we have proudly partnered with all of the leading air conditioning manufacturers. However, some are more expensive than others, so have a look at the individual brands that we supply and install including:

Tips to Save Money On Your Air Conditioning Installation

If you are looking to save some money on your air conditioning installation, consider the following tips:

  • Choose the Right Size: Make sure your AC unit fits properly into your space. An oversized or undersized unit can be less efficient and cost more over time.
  • Consider Energy Efficiency: Choosing a more energy efficient unit can be more expensive upfront but will save you money in the long run, actively lowering your energy bills.
  • Off-Season Installations: Consider installing your air conditioner during the off-season when demands are lower.
