Ask most people how long a ducted air con installation takes and they picture a week of chaos, walls opened up and rooms out of action. The reality is far tidier. For most Geelong homes, the job runs just one to three days, and you are usually enjoying cool air the same afternoon it is finished.
That timeline surprises people because ducted sounds like a big build, and in fairness it is a proper project with real craft behind it. But a good crew works to a clear sequence, most of it happening up in the roof cavity rather than through your living space. The honest range across the industry sits at one to three days on site, and the main thing that moves the needle is your home itself, not the brand on the box.
Here is how a typical whole-home install unfolds:
As a rough guide, a single-storey home with good roof access often wraps up in a day or a comfortable two, while a standard family home of around 130 to 220 square metres is generally a two day job. Larger homes above 280 square metres, two-storey builds with bulkheads, or homes with tight, low-pitch roofs are the ones that stretch toward three days.
The good news for your day-to-day is that most of this happens overhead. You can usually stay home while the crew works, there is no need to strip rooms back, and a tidy team will clean up as they go. Once the system is commissioned you can generally switch it straight on, so there is no long wait to feel the difference.
Every home is a little different, and a few things decide whether your ducted install lands at the quick or the slower end. Roof access is the big one. A generous, well-pitched roof cavity lets the team route ducts cleanly, whereas older cottages and tight ceiling spaces call for more careful work. The number of zones matters too, since more rooms and more Advantage Air zoning means more dampers, wiring and calibration. Whether your switchboard needs an upgrade to handle the new load can also add time. A proper site assessment before the job means none of this becomes a surprise on the day, and a clear timeline is set before anyone lifts a tool.
Because refrigerant work is involved, this is not a job for a handyman. By law, the copper lines must be handled by a licensed technician, so choosing an ARC-accredited installer is not just a quality choice, it is a legal one.
Here is the timing lesson. The on-site work is short, but the full window from quote to switch-on runs a few weeks once you allow for equipment lead time and scheduling, and from spring onwards installer calendars fill quickly. Leave it until the first 38 degree day and you could be waiting weeks for a spot, sweating it out in the meantime. Book now, and you can pick a date that suits you and have the whole thing done and dusted before the Geelong summer really bites.
