Mould in Air Ducts: Facts, Signs and How to Deal with It

Duct Cleaning Melbourne

Hot and damp environments are breeding grounds for mould – a fungus that can accumulate in and spread through your air ducts. Mould inside air ducts can cause a range of problems, including:

  • Poor indoor air quality.
  • Reduced HVAC efficiency.
  • Increased allergy and respiratory issues.
  • Damage to ductwork and nearby areas.
  • Persistent musty odours.

It’s very important to organise a duct cleaning service to remove mould if and when it begins to circulate. At Mr Duct Cleaning, we have over 35 years of experience with duct cleaning in Melbourne. Mould is one of the most common issues we find inside ducted heating and cooling systems.

This blog post takes a closer look at facts regarding mould, including the various types, causes and signs. It also explains how professional duct cleaners can help you deal with mould and prevent it from growing in the future.

Causes of Mould

Moisture, warm temperatures and poor ventilation create ideal environments for mould to grow. One of the most common causes of mould is having an oversized air conditioning unit that cools a space too quickly. This is because they turn off before dehumidifying the air, which leads to excess moisture that builds up and allows mould to grow. Setting AC units on very low temperatures can also cause mould growth as the cool air from the vents comes into contact with warm air in the room. Moisture in the air condenses on surfaces in and around the ducts, turning them into the perfect habitat for mould. Leaking ducts can also cause the same problem.

Types of Mould Located During Duct Cleaning in Melbourne

Any effective plan to deal with mould during duct cleaning starts with understanding the type and severity of the mould present. Mould can appear in various forms and colours, including:

  • Acremonium – Grows around air vents over months or years as a result of cooling coils and humidifiers, appearing as a powdery substance in various colours such as white and orange
  • Alternaria – A common form of mould with a velvet-like texture that shows up in dark green or brown colours, thriving in damp areas and spreading quickly.
  • Chaetomium – A brown cotton-like substance that grows in water damaged areas and tends to change colour over time, making it difficult to distinguish from other types of mould.
  • Mucor – A highly toxic type of mould commonly found in air conditioning units that can spread to air ducts, necessitating immediate remediation.
  • Stachybotrys A black toxic mould that can cause various health issues and is easy to spot but often goes unnoticed as it forms deep inside air ducts with a good amount of moisture.

Signs of Mould

There are multiple signs and symptoms of mould in and around your air ducts, including:

  • A musty and unpleasant odour when your HVAC system is running
  • Visible mould in the vicinity of air vents, grilles and drip pans
  • Allergy-like symptoms such as congestion, itchy eyes and sneezing

Other health issues that signify the presence of mould can include fever, insomnia, nausea, dizziness and headaches. It’s worth arranging duct cleaning in Melbourne if any of these signs are apparent.
