SolvedIndoor Air Quality
What would you ask before approving indoor air quality work in Wollongong?
Asked by James Brooksin Wollongong, New South Wales· 4/8/2026· 1949 views
I'm in Wollongong, New South Wales and dealing with a 18-year-old whole-home air quality setup in our townhouse. Over the last three days, it has been leaving the house dusty and humid even after service and we're now noticing the technician who came out last time did not leave any actual readings behind.
One contractor quoted A$820 for repair, while another jumped straight to a A$17,801 replacement because of the age. The weather here has been dealing us coastal humidity, so I do not want to wait too long, but I also do not want to approve the wrong scope.
If you were comparing bids on this, what would you want checked first? I especially want to know how much weight you would give to return leaks, filtration sizing, humidity readings, and fan run settings.

The recommendation should be tied to measurements, not just the age of the equipment. Age matters, but it is not a diagnosis on its own. For a whole-home air quality setup that is leaving the house dusty and humid even after service, the first things I would ask for are return leaks, filtration sizing, humidity readings, and fan run settings. If the contractor is recommending bigger work, ask them to explain which measurement supports that recommendation and whether they ruled out airflow or controls first. In Wollongong, New South Wales, pricing can move around, but the diagnostic process should still be clear.

From a contractor side, I would not approve a major repair or replacement without test results that line up with the symptoms.

What helped us most was breaking the quote into labour, parts, warranty, and optional upgrades. The expensive bid looked very different once it was itemized. We had a related issue with our whole-home air quality setup in Wollongong. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

The price range alone does not tell you enough. Ask what was tested, what failed, and which assumptions are built into the quote.

Before signing anything, I would ask the technician to show the readings and explain which number actually supports the recommendation.

I would compare how clearly each contractor explains the diagnosis, not just the price. The clearer company ended up being the better hire for us.

We used the directory reviews to filter out firms that were vague about what they had actually tested. That saved us a lot of time.

If you can, ask whether they checked airflow before recommending equipment. We nearly replaced a system when the bigger issue was elsewhere.
