What makes ducted worth considering?

Ducted systems offer more than a different way to cool the house. Their centralised design can make them particularly appealing when several rooms need regular heating or cooling.

Ducted air conditioning

One system across multiple rooms

Instead of operating separate air conditioners throughout the house, a ducted system distributes conditioned air to multiple areas from a single central unit.

Ducted reverse cycle

Keep more of your walls clear

Ducted systems can be installed in the ceiling space or beneath the floor, depending on your home’s layout and available access. Discreet outlets deliver air without taking up wall space.

Temperature Changes

Comfort through changing seasons

With ducted air conditioning, the same system can deliver cooled air during hot weather and heat during cold weather.

What does ducted air conditioning cost?

There isn’t one price for a ducted installation because every home and system setup is different. The size of the property, installation requirements and chosen system all influence the final quote.

Typical ducted air conditioning costs 

The price depends on the system, property and work required. Indicative costs can include: 

  • Ducted system installation: around $6,000–$10,000 for many 3–4 bedroom homes
  • Routine ducted servicing: around $80–$350+
  • Ducted air conditioning repairs: around $70–$2,500+, depending on the fault
  • Refrigerant-related repairs: around $160–$1,600+, depending on the issue

What can change the final price? 

System size, selected features, installation access and the work required can all affect the final price. For servicing and repairs, system condition, fault type and replacement parts also influence costs.

  • Larger homes can require higher-capacity equipment.
  • Zoning and Wi-Fi controllers can add to installation costs.
  • Bar grilles and ducting with higher insulation ratings can affect pricing.
  • Access, system condition and replacement parts influence servicing and repair costs.

Frequently asked questions

Thinking about ducted air conditioning for your home? Here are answers to common questions about installation, costs, system suitability and what to expect before the work begins.

Can ducted air conditioning be installed in an existing home?

It can be possible to install ducted air conditioning in an existing home, but the property needs to be assessed first. Available space, access and the installation requirements all influence what can be achieved. Trimech can inspect your home and recommend a suitable approach. 

How much does ducted air conditioning installation cost?

There isn’t a single price that applies to every home. The cost of ducted air conditioning can vary based on the property, system requirements, areas being conditioned and complexity of the installation. A site assessment allows Trimech to prepare a quote based on the actual job. 

How long does ducted air conditioning installation take?

Installation time depends on the home, system and work required. A straightforward installation may differ from that of a larger or more complex property. Once Trimech has assessed your home and planned the installation, we can provide a clearer idea of what to expect. 

Will a ducted system cost more to run?

Running costs depend on factors such as the system selected, how often you use it and your temperature settings. Choosing an air conditioning system suited to the property is important, which is why Trimech assesses your requirements rather than recommending the same setup for every home. 

Do I need to prepare my home for installation?

Preparation will depend on the installation. Before work begins, our team can explain what access is required and anything you need to move or prepare. This helps make installation day more straightforward and ensures our technicians can access the areas they need to access.
