Indoor Air Quality
What would you ask before approving indoor air quality work in Wollongong?
Asked by James Brooksin Wollongong, New South Wales· 4/18/2026· 1970 views
I'm in Wollongong, New South Wales and dealing with a 10-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 we are trying to decide this week and i do not want to sign off blindly.
One contractor quoted A$293 for repair, while another jumped straight to a A$13,798 replacement because of the age. The weather here has been dealing us sudden shoulder-season temperature swings, 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.

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

We had something similar and the turning point was asking each company for the actual readings in writing instead of a verbal explanation. 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.

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.
