If you don’t clean the air conditioning filter, it can become clogged with dust, dirt, and other particles. This reduces airflow, forcing the system to work harder, which can lead to reduced efficiency, higher energy costs, and increased wear on the system. A dirty filter can also negatively affect indoor air quality, leading to potential health issues.

Signs that your AC air filter may be dirty include reduced airflow, an increase in dust or other allergens inside your home, a musty or dusty odour coming from the outlets, increased energy bills, and even ice formation or dripping on the indoor air conditioner in cooling. Regular inspection, especially during peak usage seasons, can help identify a dirty filter before it leads to more serious issues.

Depending on the type of air conditioning filter, it may be possible to clean it instead of replacing it. Reusable filters can often be cleaned with water. Disposable filters, on the other hand, generally need to be replaced when dirty. Keep in mind, though, that when an air conditioner filter is at the stage of being visibly dirty, it can indicate the AC is also due for a professional maintenance.

Yes, a dirty air filter can restrict airflow, causing the system to work harder to cool the air. This can reduce the efficiency of the air conditioner, leading to inadequate cooling. Over time, this strain can cause other parts of the system to wear out prematurely, further impacting the cooling capability.

In Sydney, where the climate can be warm and humid, it is generally recommended to have your air conditioner serviced at least once a year, preferably before the summer season. However, for optimal performance and efficiency, scheduling a professional service every six months may be beneficial. Regular servicing with a trusted provider like Proven Air Conditioning & Electrical can help in identifying and addressing any potential issues before they become major problems.
