Expert Insights from Direct Point Heating & Cooling – Melbourne
Your air conditioner might appear to be functioning without issues, but if you haven’t cleaned the filters in a significant amount of time, you could be losing as much as 30% of your system’s cooling efficiency. This decline in performance can drastically impact your comfort levels during the scorching Australian summer, making it vital to address.
Clogged filters are a primary culprit behind diminished airflow, escalating energy bills, and compromised indoor air quality. While cleaning filters may seem like a straightforward task, there is a specific procedure that must be followed to attain the best outcomes.
This extensive guide will take you through the detailed steps necessary for cleaning your filters, emphasize the importance of routine maintenance, and highlight the signs that suggest when it is time to call in a professional for a thorough system clean.

Understanding the Crucial Importance of Regular Filter Cleaning
The filters in your air conditioning system play a pivotal role in capturing dust, allergens, and various other contaminants before they pollute the air you breathe. However, as time passes, these filters can become clogged, leading to increased pressure on your system, restricted airflow, and even the potential growth of mould within the unit.
Consistent cleaning of your filters is essential for:
- Maximizing overall system efficiency
- Lowering energy consumption
- Prolonging the lifespan of your air conditioning unit
- Improving indoor air quality for your family
Neglecting this critical maintenance can result in higher operating costs, more frequent breakdowns, and air that may pose health risks to your loved ones.
Detailed Guide: How to Effectively Clean Your Air Conditioner Filter
Step 1: Power Down and Unplug Your Unit for Safety
Before you start the cleaning process, it’s vital to ensure that the power is entirely turned off. For wall-mounted split systems, turn off the power at the wall and unplug the unit. If your system is hardwired, make sure to switch off the dedicated circuit at your switchboard, ensuring your safety while you clean.
Step 2: Carefully Extract the Filter from the Unit
Gently open the front panel of your indoor unit. Carefully slide out the filter, taking care not to bend or damage the mesh. Be aware that some units may have clips or latches that need to be released before you can remove the filter.
Step 3: Clean the Filter with Gentle Soap and Water
Fill a tub or sink with lukewarm water and incorporate a small amount of mild detergent. Let the filter soak for several minutes, then utilize a soft brush to gently scrub away any built-up dust or grime. Avoid using harsh chemicals or scrubbing too vigorously, as this could compromise the integrity of your filter.
Step 4: Ensure Complete Drying of the Filter Before Reinstallation
Shake off any excess water and place the filter in a well-ventilated area to air dry, avoiding direct sunlight. It is crucial not to reinstall a damp filter, as moisture can foster the growth of mould and bacteria within your air conditioning system.
Step 5: Reinsert the Filter and Evaluate System Performance
Once the filter is completely dry, slide it back into its designated position, close the panel, and switch your system back on. After powering it up, check that the airflow feels strong and consistent, which indicates that the cleaning process was successful.
Assessing if DIY Cleaning is Sufficient for Your Air Conditioner
While regular filter cleaning is vital, it addresses only surface-level issues. Your air conditioning unit requires professional servicing to effectively eliminate:
- Accumulated dust and mould within the fan and coils
- Blockages in drain trays and internal components
- Efficiency losses caused by dirty or malfunctioning parts

Recommended Frequency for Cleaning Your Air Conditioner Filters for Optimal Performance
We generally advise the following cleaning schedule:
- For typical household use: Every 2–3 months
- For households with allergies or pets: Monthly
- For commercial spaces or high-usage systems: Monthly or even more frequently
Additionally, we recommend scheduling professional servicing at least once a year to ensure your system runs efficiently and to prevent the risk of costly breakdowns.

- Thorough cleaning of all filters, fans, coils, and drain trays
