Melbourne Inner and NW Suburbs - Heating and Air Conditioning Repairs Service

There are several reasons why mould may develop in an air conditioner:

1. Moisture Buildup: Air conditioners can create a moist environment inside the unit, especially if it is not properly ventilated. This can lead to the growth of mould and mildew.

2. Dirty Filters: Dirty air filters can restrict airflow and allow moisture to accumulate, which can provide a suitable environment for mould growth.

3. Duct Leaks: Leaks in the ducts can allow moist air from outside to enter the system and create a breeding ground for mould.

4. Poor Drainage: Air conditioners that are not draining properly can also lead to mould growth, especially if there is standing water in the unit.

To prevent mould from growing in your air conditioner, it’s important to have it serviced regularly, keep the filters clean, repair any leaks in the ducts, and ensure proper drainage. If mould is already present, it’s best to have it professionally cleaned to avoid spreading mould spores into your home and to ensure that it is removed completely.
