The Complete Ducted Air Conditioning Cost Breakdown

To comprehensively understand the costs, let’s take a closer look at the different aspects involved:

How Much to Install Ducted Air Conditioning?

The cost of installing a ducted air conditioning system can be a substantial upfront expense. The total cost depends on several factors, including the size and complexity of the system, and whether your home has existing ductwork. Typically, you’re looking at expenses ranging from $5,000 to $10,000, possibly more. Homes with existing ducts might find the cost more manageable, whereas those needing new ductwork will face higher expenses.

Ongoing Operational Costs

Beyond the initial cost of installing ducted air conditioning, it’s important to consider the continuous air conditioning running costs. Ducted systems are known for their efficiency, but they will still be a part of your monthly bills. Annual running costs can vary greatly, depending on the system’s efficiency, local electricity rates, and how often you use it. Generally, you can expect to spend between $300 and $1,500 per year.

Costs for Potential Upgrades

Ducted air conditioning systems can come with optional features or upgrades, especially if you already have central ductwork. For example, adding cooling to an existing ducted heating system is a possibility. This kind of upgrade can cost $3,000 to $6,000 or more, depending on the required work.

Is Ducted Air Conditioning Worth It?

Ducted air conditioning offers consistent comfort and temperature distribution throughout your home. It can also improve your home’s value and air quality. Still, it’s crucial to balance these benefits against the initial and ongoing costs to see if it’s the right choice for your budget and lifestyle.

Which is Cheaper to Run: Ducted or Split System?

While ducted systems have a higher initial cost, their energy efficiency can lead to long-term savings. However, the actual cost-saving benefits will depend on your usage patterns and local energy costs.

Before you make your final decision and pay

So, you think you might be ready to make a decision.  Before you go ahead and make your selection, here’s some advice to consider.

  • Ensure you have got two to three quotes for comparison.  This will also allow you to get a sense of what the current market rates are.
  • If one quote is for a drastically lower-capacity system, be careful, as the system will not work to cool the house as required.
  • You may notice that different systems of the same capacity may have different prices.  Before choosing the lowest price quote, take a careful look at every detail and ask why their package may cost more or less than the others.
  • Ensure your installer is licensed.
  • Look for someone with plenty of testimonials and happy clients.
  • Most importantly, the air conditioning industry is guided by regulations placed by the Department of Fair Trading.  It allows contractors to charge a maximum deposit of 10%.  If a contractor asks for higher deposits or phased payment, refer them to the department’s rules. 

At Peninsula Air Conditioning we strongly abide by these guidelines and you will only receive a final bill only once the installation is completed, usually a day or two afterwards.
