No one likes to find mould in their home, and it can be a horrifying scenario when it starts growing in your air conditioner. Mould only needs three things to start growing moisture, oxygen & organic matter (a source of food) all of which are found in Brisbane air conditioners. Thankfully, there are a few things you can do to prevent mould growth in your AC unit and some steps to take if you find that you already have a mould problem. This article provides some tips on how to deal with mould in your air conditioner and in your home.
Mould in aircon can cause health problems
Mould is a type of fungi that can grow both indoors and outdoors and is commonly found in damp or humid environments which are the ideal conditions for mould to grow. Even 5 years ago, the effect of mould and other fungi was not that well known but we now know that when mould spores are inhaled, they can cause a range of health problems including allergic reactions, lung disease, mould allergies, respiratory infections and chronic illnesses such as asthma and other health risks. In some cases, mould exposure can even lead to death. Therefore, it is essential that mould in aircon evaporator coils is removed as soon as possible to protect your health.
Symptoms of mould in aircon such as blocked nose, sore throat, coughing, wheezing, watery eyes and skin rashes can all indicate that you have aircon mould, you may even notice a musty smell when your air conditioner is running.
If you have a mould infestation in your air conditioner you may notice some of the symptoms:
- Musty smells, foul mildew smells, stale odours or other unpleasant smells.
- Black dust or mould marks on the ceiling around your air conditioner grilles or vents.
- Throat irritation, sinus coughs, nasal congestion and minor respiratory problems.
- Consistently high humidity levels in the home that your air conditioner is unable to reduce.
How to confirm if you have mould in your air conditioner
You can purchase DIY kits to test for mould in aircon, these kits are relatively cheap and will confirm if you 100% have mould in your home. We recommend the SAN-AIR Mould & Bacteria Test Kit which can be purchased online for around $160 and will also test for bacteria and yeast which are food sources that enable mould to grow.
Mould in aircon can damage property
Mould can cause the coils in an air conditioning unit to rust as the mould keeps the cooling coils moist all the time & never gives them time to dry out. Rusty coils can damage the unit & lead to refrigerant leaks. Mould can also cause paint to peel and wood to rot in your home if left to get out of hand.
Mould in air conditioning units can also lead mould to grow on clothes and other household items as the mould spores are distributed throughout the home by the air conditioner’s indoor fan. Mould can cause the fabric to rot and the colours to fade. If mould is present in an air conditioning unit, it is important to remove it as soon as possible to prevent mould from growing on clothes.
Mould can also grow on food. Mould can cause food to spoil and make it unsafe to eat. If mould is present in food, it’s best to dispose of it as soon as possible to prevent food poisoning.
If mould is present in an air conditioning unit, it should be removed as soon as possible to prevent any damage to property.

6 easy steps to keep your air conditioner mould free
- Get your air conditioner serviced at least once per year to prevent mould growth, the cost of an air conditioner service is quite low especially when your family’s health is at risk.
- If you have had your air conditioner running in cooling mode, rather than turn the system off when you leave home just change it to fan-only mode to allow the system to dry out.
- Clean your return air filter at least every three months (the more frequent the better), if you notice the filter is still dirty or worn out after cleaning book your local air conditioning repairer to come out and install new filter media.
- Wipe down your air conditioner grilles with a surface mould remover spray, these can be found online or at your local Bunnings.
- If you have unusually high humidity in your home look into installing a ducted dehumidifier to keep the relative humidity between 30-60% which will also help prevent mould growth.
- Consider adding some form of air purification system to your ducted air conditioner, products such as REME HALO by RGF use UV light and a photocatalyst material to generate ions that inhibit mould.
