Anyone dealt with a duct system pushing weak airflow to the upstairs rooms in Melbourne?
Asked by Ella Singhin Melbourne, Victoria· 3/31/2026· 1957 views
I'm in Melbourne, Victoria and dealing with a 8-year-old duct system in our townhouse. Over the last month, it has been pushing weak airflow to the upstairs rooms 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$945 for repair, while another jumped straight to a A$8,700 replacement because of the age. The weather here has been dealing us hot afternoon cooling demand, 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 duct leakage, balancing, blower performance, and filter pressure drop.

If you can, ask whether they checked airflow before recommending equipment. We nearly replaced a system when the bigger issue was elsewhere. We had a related issue with our duct system in Melbourne. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

Before signing anything, I would ask the technician to show the readings and explain which number actually supports the recommendation. For a duct system that is pushing weak airflow to the upstairs rooms, the first things I would ask for are duct leakage, balancing, blower performance, and filter pressure drop. 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 Melbourne, Victoria, pricing can move around, but the diagnostic process should still be clear.

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

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 duct system in Melbourne. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

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 duct system in Melbourne. 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. We had a related issue with our duct system in Melbourne.

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 duct system that is pushing weak airflow to the upstairs rooms, the first things I would ask for are duct leakage, balancing, blower performance, and filter pressure drop. 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.
