Straight Answer

Duct cleaning vs duct replacement — which do you need?

For most Melbourne homes, the honest answer is cleaning, not replacement. Ducting that looks filthy usually cleans up beautifully. Replacement is only the right call when the ducting is physically damaged, collapsed, or deteriorated beyond what cleaning can fix. Here's how to tell the difference — and we'll always tell you the truth.

When Cleaning Is Enough

Most ducts just need a proper clean

If your ducting is intact but dirty, cleaning restores it — at a fraction of the cost and disruption of replacement.

  • ✓ Heavy dust, debris or pet hair build-up
  • ✓ Musty smells or circulating allergens
  • ✓ Reduced airflow from contamination
  • ✓ Surface mould on otherwise sound ducting
When Replacement May Be Needed

The few cases cleaning can't solve

We'll flag it honestly if your ducting genuinely needs repair or replacement:

  • ✕ Crushed, collapsed or disconnected ducting
  • ✕ Holes, tears or rodent damage
  • ✕ Mould that keeps returning after cleaning
  • ✕ Ducting that has simply aged out

Even then, we can handle repairs or replacement — but only after telling you honestly whether you actually need it.

FAQ

Cleaning vs replacement — your questions

Should I clean or replace my ducts?
In most cases, cleaning is all you need — replacement is only warranted when ducting is physically damaged, collapsed, heavily mould-affected beyond cleaning, or badly deteriorated with age. We inspect honestly and tell you which one you actually need.
How do I know if my ducts are damaged beyond cleaning?
Signs include crushed or disconnected ducting, persistent mould that returns after cleaning, visible holes or tears, or ducting that has simply aged out. An inspection confirms it quickly.
Isn't replacement always better?
No. Replacement is far more expensive and disruptive, and most ducting cleans up beautifully. We'll never recommend replacement to upsell you — only when cleaning genuinely won't solve the problem.
What does an inspection involve?
We assess the condition of your ducting, the level of contamination, and whether there's any physical damage — then give you a clear, honest recommendation and quote.
Can you replace ducts if needed?
Yes — where ducting genuinely needs replacing or repair, we can handle that too. But we start by telling you the truth about whether you need it.
