A single-storey, three-bedroom home with good roof access and no major electrical work is normally the quickest job on the books. A double-storey home or one with more rooms and more zones naturally takes longer, since there's more ductwork to route and more dampers and vents to fit. Suppose your installer is also removing an old ducted gas heater; that adds a step to the day. Electrical upgrades, if your switchboard needs work to handle the new system, can add time as well.
It's worth asking your installer for a realistic estimate at the site inspection stage, rather than relying on a generic timeframe. Every home is different, so what took a day next door might reasonably take longer at yours.

A few things can push a straightforward job into a longer one. It's useful to know about these before booking, so you're not caught off guard:
- Limited roof space: Older homes with low or awkward roof cavities can make routing ductwork slower.
- Electrical upgrades: If your switchboard can't handle the new system, an electrician may need extra time before the air conditioner itself goes in.
- Older homes: Existing insulation, uneven ceiling heights or previous renovations can all add complexity.
- Weather: Wet or windy conditions can slow down outdoor unit installation, particularly if the outdoor compressor needs to go somewhere exposed.
- Custom zoning: More zones mean more dampers, sensors and controllers to install and test.
- Removing an old gas ducted heater: Disconnection, decommissioning and removal all take time before the new system can go in.
None of these should necessarily blow out your timeline, but they're worth raising with your installer at the quote stage so you know what to expect.
A professionally carried Melbourne ducted air conditioning installation follows a fairly consistent pattern, even though the exact order can vary between installers.
Morning: The team arrives, confirms the plan from your site inspection and sets up. This usually includes protecting floors and furniture near the work areas.
Roof and ceiling work: Installers mark grille locations, cut ceiling holes where needed and route the flexible ductwork back to the main unit. The indoor unit itself is typically suspended in the roof cavity.
Outdoor unit: The outdoor compressor is positioned and connected. Its placement matters, since it needs to sit away from bedrooms where possible and have enough clearance for airflow and future servicing.
Electrical and refrigerant connections: An electrician wires the power circuit and controls, while refrigerant pipework is connected and tested for leaks between the indoor and outdoor units.
Testing: Once everything is connected, the system is run through both heating and cooling modes and each zone is checked individually to confirm it's working properly.
Handover: Before the team leaves, they should walk you through the controls, answer any questions and explain basic maintenance, like when to clean or replace filters.
For an average-sized home, all of this can often be done in a single day. Larger or more complicated jobs may simply carry some of these steps into a second day, rather than requiring a completely separate visit.
Ducted air conditioning installation cost is genuinely one of the harder questions to answer with a single figure, since it depends on so much: system size, brand, number of zones, roof access and whether any electrical or removal work is involved. Based on current Melbourne pricing guides, a typical ducted installation could sit somewhere between $8,000 and $20,000, with larger homes, heavily zoned systems or premium brands sometimes pushing higher.
A few things that generally affect the final number:
- Home size and layout: More rooms and more square metres mean more ductwork and a bigger capacity system.
- Number of zones: Each zone adds a damper, sensor and extra labour, so more zones usually mean a higher price.
- Roof access and construction type: Homes with tight or awkward roof cavities or heritage restrictions on outdoor units can cost more to work on.
- Removing an existing system: Taking out old ducted gas heating adds to the job.
- Brand and system capacity: Higher-capacity or premium reverse cycle systems cost more upfront, though they may be more efficient to run.
Since pricing varies this much, a fixed quote from a licensed installer after an in-home assessment is a far more reliable figure than any general online estimate, including this one.
Probably, yes. The Victorian Energy Upgrades (VEU) program offers upfront discounts on efficient reverse cycle air conditioners, including ducted systems, as part of the wider Victorian air conditioner rebate scheme. As it currently stands:
- Based on Victorian Government estimates, some households may save up to around $460 per year, although actual savings depend on home size, climate and energy usage.
- If you're removing or replacing an existing ducted gas heater with an efficient reverse cycle ducted system, eligible households may receive discounts of up to around $5,530. But this depends on the eligible system, greenhouse gas savings, VEEC market value and accredited provider pricing.
- Eligible homes may receive discounts of up to approximately $1,610, depending on the approved product and VEEC calculation.
The discount is applied directly to your quote by an accredited provider, so there's no separate claim form. To be eligible, the system needs to appear on the VEU product register and come with a minimum five-year warranty and if you're replacing an existing system, it generally needs to be more than two years old.
Rebate amounts and eligibility rules can change, so it's worth checking the current details on the Victorian Energy Upgrades page or asking your installer to confirm before you book.

In case you are eligible for the rebate, get in touch with our team to get a realistic timeline and cost estimation for your project. We will make sure you make the maximum possible savings on your ducted air conditioning installation.
A few simple checks go a long way here:
- Confirm they hold a current ARCtick licence for refrigerant handling, since this is a legal requirement in Australia.
- If you're chasing a VEU rebate, check they're an accredited provider or ask whether they can work with one.
- Get more than one quote. Comparing a couple of options helps you see whether zoning, brand and pricing genuinely line up with what you need, rather than settling on the first number you're given.
- Ask about warranty terms upfront. VEU-eligible systems need a minimum five-year warranty and it's worth knowing what's covered beyond that.
- Ask how they handle delays. A good installer should be upfront about what could push your job into a second day, rather than leaving you to find out on the day itself.
Choosing an installer is ultimately a calculated decision, not just a price comparison. The cheapest quote isn't always the most useful one if it skips over roof access issues or zoning needs that come up later.
For most Melbourne homes, a ducted air conditioning installation is a one- to two-day job, with cost and timeline both shaped by your home's size, layout and any extra work like electrical upgrades or old system removal.

Yes, generally. Most installers need someone on site to confirm grille and zone locations early in the day and to sign off on the system during testing and handover.
5) Can ducted air conditioning be retrofitted into an existing home?
In most cases, yes. Ducted systems are more straightforward to install during a build or renovation, but licensed installers regularly retrofit ducted air conditioning into existing homes, provided there's enough roof space to route the ductwork.
6) How often does a ducted air conditioning system need servicing?
Most manufacturers recommend a professional service around once a year, with filters cleaned more regularly at home in between. Your installer should confirm the specific schedule for your system at handover.
