Why Your Air Conditioner Smells and How We Fix It in Andrews Farm

Odour is a symptom, never the fault itself. Andrews Farm homes run their cooling hard through dry Adelaide summers, and anything sitting on a coil or in a duct gets pushed straight into your living room with every cycle.

We diagnose the smell before we quote. That way you pay for the actual fix, not a guess, and the price is fixed in writing before any work starts.

Aged evaporative pads

How it works

Safe Checks Before You Call Anyone

A couple of checks cost nothing and sometimes solve the problem outright.

  1. 1

    Check the filter

    If it is grey and matted, wash or replace it and run the unit again.

  2. 2

    Check the drain

    Water sitting in the indoor unit's tray breeds the musty smell fast.

  3. 3

    Check the pads

    Evaporative owners can look for pads that are crumbling, scaled or dark.

  4. 4

    Trust your nose

    If the smell is burnt, fishy or chemical, stop and call us instead of testing further.

If the smell arrives with other symptoms, our pages on an air conditioner leaking water or error codes cover the faults that often travel together.

When a Smelly Air Conditioner Needs Urgent Attention

Most odours are a cleaning job, but a few are a warning. Call us the same day if you notice any of these, because each one can escalate.

  • A burnt, fishy or hot-plastic smell that returns every time the unit starts
  • The smell getting stronger while the airflow gets weaker
  • Any odour paired with tripping switches or a unit that cuts out mid-cycle

We hold 24/7 emergency availability, backed by our Within-the-Hour Response for urgent issues where availability allows.

Questions

Air Conditioner Smell FAQs

Why does my air conditioner smell musty when it starts?

A musty blast at start-up usually means mould or bacteria on the coil or in the drain pan, and a professional clean of the coil, filter and line removes the source rather than masking it.

Is a burning smell from an air conditioner dangerous?

Yes, a burning or electrical smell means you should switch the unit off at the wall and call us, because a failing motor, wiring fault or cooked component can escalate into a real hazard.

Can a dirty filter make the whole house smell?

It can, because a choked filter traps dust and pet dander and every cycle pushes that odour back into your rooms, which is why filter checks come first on every odour callout.

How do I stop the smell from coming back?

Book a clean before each summer, replace or wash filters as the manual directs, and keep the outdoor unit clear of leaf litter, because a system that stays clean stays smelling clean.
