Ducted Air Conditioning Installation in Melbourne

Whole-home comfort, zoning and room requirements

A ducted system cools and heats every room it's connected to from one controller. Zoning splits the house into areas, such as living rooms and bedrooms, that can be turned on and off separately, so you aren't conditioning rooms nobody is using.

We'll ask how you use the house during the day and at night, which rooms get the most sun, and whether some rooms need to be warmer or cooler than others. That shapes how many zones you need and where they fall.

Roof space, ducts, outlets and return-air planning

The indoor unit needs enough height and a safe platform in the roof space, or space under the floor. Ducts then run to an outlet in each room, sized to deliver the right amount of air. A return-air grille, usually in a hallway, draws air back to the unit.

Low-pitched roofs, tight access hatches and existing services can all limit where things go. We check these during the assessment and plan around them.

New installation versus replacement

In a home with no ducts, everything is new: the unit, ducts, outlets, return air and controller. In a home with an existing ducted system, we check whether the ducts and outlets are in good enough condition and the right size to reuse with a new unit.

Reusing sound ductwork can reduce the cost of a replacement. Damaged, undersized or poorly insulated ducts are better replaced at the same time.

What drives project price and disruption

Price depends mostly on system capacity, the number of zones and outlets, the length and difficulty of the duct runs, and roof access. The work happens mostly in the roof space, with outlets cut into ceilings and the outdoor unit placed outside.

• System capacity and number of zones
• Number and position of outlets and return-air grilles
• Roof space height and access
• Reuse or replacement of existing ducts
• Electrical work and controller type

Commissioning, controls and maintenance handover

Once installed, we run the system in cooling and heating, check the air coming out of every outlet and balance the airflow between zones. We set up the wall controller and any app control and show you how to use the zones.

Ducted systems need regular filter cleaning and a periodic service. We'll explain what to do yourself and when to book a service.
