What exactly is mould?
When we hear the word “mould” we instinctively know it’s not something we want to deal with — but what exactly is it? Mould is a type of fungi that flourishes in damp, poorly ventilated spaces and thrives on plant and animal matter. When you notice the first signs, it needs to be addressed promptly — the longer you leave it, the worse it gets. Mould reproduces quickly by releasing airborne spores that spread rapidly, becoming a major issue for both your health and your property. It can spread across walls, ceilings, flooring and carpets, and is commonly found in damp buildings.
Health risks of mould in your air conditioner
Mould can grow in your AC unit, and when it does it can be hazardous to your health — particularly for individuals with respiratory issues and allergies. Because it compromises the overall air quality in your living or working space, and because air conditioners are an ideal breeding ground if not properly maintained, it’s essential to address mould problems promptly.
- Respiratory issues — inhaled spores can lead to coughing, wheezing, shortness of breath, throat irritation and nasal congestion, especially for people with allergies or asthma.
- Allergic reactions — sneezing, a runny or stuffy nose, itchy eyes and skin rashes. Prolonged exposure can worsen these symptoms over time.
- Infections — some moulds produce mycotoxins, which can lead to infections if they contact vulnerable areas such as open wounds or mucous membranes.
- Headaches and fatigue — breathing in spores can result in persistent headaches and general fatigue.
- Exacerbation of existing conditions — people with conditions such as COPD may experience worsening symptoms.
Causes of mould growth in air conditioners
- Humidity — as warm air is cooled, moisture condenses on the coils; if not drained properly, this leads to mould development.
- Poor maintenance — dust, dirt and organic debris accumulate in a neglected unit, and mould feeds on these organic materials.
- Improper sizing — an incorrectly sized unit may not cool effectively, leading to increased humidity and condensation.
Prevention is better than the cure
- Regular maintenance — schedule routine servicing, including cleaning or replacing filters, inspecting coils and ensuring proper drainage.
- Keep the area dry — address any water leaks or condensation issues promptly.
- Control humidity — use a dehumidifier to maintain optimal indoor humidity, especially in humid weather.
- Proper ventilation — ensure good air circulation where the air conditioner is installed.
- Professional inspection — if you suspect mould, contact a professional technician to inspect, service and clean the unit thoroughly.
