Aircon Mould Removal Melbourne

Air conditioning systems create ideal mould conditions: they produce condensation on evaporator coils and drip trays, they operate in dark enclosed spaces, and they circulate air that carries mould spores. When the system is off, residual moisture sits in the unit and ductwork, allowing mould to colonise. Melbourne's ducted heating systems can also develop mould when condensation forms in ductwork during the transition between heating and cooling seasons.

Aircon mould removal in Melbourne typically costs between $300 and $1,500 per system. Split system cleaning and treatment is at the lower end ($300-$600), while full ducted system cleaning including all ducts, plenums, and the central unit ranges from $800-$1,500.

Yes, mould in air conditioning is particularly dangerous because the system actively distributes spores throughout every room it services. When the system runs, it can blow thousands of mould spores directly into occupied rooms. This causes respiratory irritation, allergies, headaches, and can trigger asthma attacks. People who notice symptoms worsen when the heating or cooling is running should suspect HVAC mould.

Signs of mould in your air conditioning include a musty or stale smell when the system runs, visible dark spots on vents or around the unit, allergy or respiratory symptoms that worsen when the system is operating, dark residue on surfaces near air outlets, and visible mould inside split system units when you open the front panel. If your ducted system has not been professionally cleaned in several years, mould is likely present.

Split system air conditioners should be professionally cleaned annually, ideally before summer. Ducted heating and cooling systems should be professionally cleaned every 3-5 years, with filters changed or cleaned every 3-6 months. If you notice musty smells or have had water damage to ductwork, immediate cleaning is warranted regardless of the schedule.

Yes, Melbourne's popular ducted gas heating and reverse-cycle ducted systems can spread mould throughout the home. Mould growing in ductwork, the return air box, or the central unit is distributed to every room with a vent when the system operates. This is why duct cleaning is important — it addresses mould that would otherwise be continuously circulated through your living spaces.
