Keep Your Air Conditioning Running Smoothly with Regular Maintenance
Learning how to clean air conditioner filter properly is one of the most important skills every homeowner should master. A well-maintained air conditioner not only keeps your home comfortable but also saves you hundreds of pounds on running costs whilst improving indoor air quality for your family. Whether you own a split system air conditioner or a ducted system, regular cleaning of your air filters can reduce energy consumption by up to 15% and significantly extend your unit’s lifespan.
Many Australian homes suffer from poor air conditioning performance simply because owners neglect this simple yet crucial maintenance task. The good news? Cleaning your air conditioner filters is surprisingly straightforward and requires no professional service when done correctly.
Why Regular Air Conditioner Filter Cleaning Is Essential
Slash Your Energy Bills and Improve Your Health
Your air conditioning system works tirelessly to maintain comfortable temperatures, but dirty air conditioner filters force the unit to work much harder than necessary. When filters become clogged with dust, pet hair, and debris, airflow becomes restricted, causing your air conditioner to consume significantly more electricity.
Clean air filters allow your indoor unit to operate at peak efficiency, reducing energy consumption and keeping those electricity bills manageable. Beyond the financial benefits, regular cleaning dramatically improves indoor air quality by removing allergens, dust mites, and pollutants that can trigger respiratory issues and allergies.
A clogged filter doesn’t just affect your wallet; it can seriously damage your air conditioning unit. When airflow is restricted, the system’s components work under strain, potentially leading to costly repairs or premature replacement of the entire unit.

Essential Tools for Air Conditioner Clean Success
Gather Everything You Need Before You Start
Before you begin to clean your air conditioner, it’s crucial to have the right equipment ready. Proper preparation ensures you can complete the entire cleaning process efficiently without interruptions. Having everything organised beforehand also prevents potential damage to your air conditioning unit and guarantees the best possible results for your maintenance efforts.
Essential Cleaning Tools:
- Vacuum cleaner with a brush attachment to remove excess dust effectively
- Soft brush for gentle scrubbing without damaging delicate filter materials
- Warm soapy water using mild detergent (avoid harsh chemicals that could damage filter fibres)
- Soft cloth for wiping down surfaces
- Access to running water for thorough rinsing
Safety Equipment:
- Gloves to protect your hands from dust and cleaning solutions
- Safety glasses if you’re dealing with particularly dusty conditions
- Your instruction manual or user manual handy, as different models may have specific requirements for accessing and cleaning filters
Once you’ve gathered all these essential items, you’ll be well-equipped to tackle the cleaning process safely and effectively. This investment in proper preparation will save you time and ensure you achieve professional-quality results. Remember, using the correct tools not only protects your air filters but also maintains your warranty coverage with most manufacturers.
8 Steps to Clean Air Conditioning Filters
Step 1: Power Down Your Air Conditioning System Safely
Safety must always come first when you clean your air conditioning unit. Switch off your air conditioner completely using the remote control or wall switch, then unplug the unit from the mains power supply. For split system air conditioners, ensure both the indoor unit and outdoor compressor unit are completely powered down.
Wait at least 10 minutes after switching off to allow all internal components to stop moving and cool down. This prevents any risk of injury and protects the electronic components from damage during the cleaning process.
Step 2: Access Your Air Conditioner’s Front Panel
Locate your air conditioner’s front panel, this varies depending on whether you have a split system or ducted system. For split system air conditioners, the front panel typically lifts or slides open to reveal the air filters inside. Ducted systems usually have filters located at the return air grille.
Consult your instruction manual for specific guidance on opening your particular model, as forcing the wrong panel could cause damage. Some units have clips or latches that need to be pressed before the panel will open properly.
Step 3: Carefully Remove the Air Filters
Gently slide or lift the air filters out of your indoor unit, taking note of their orientation and position. Most air conditioner filters are designed to be easily removable, but avoid using excessive force as this could damage the filter frame or the unit itself.
If you have multiple filters, remove them one at a time and remember their exact placement, taking a quick photo with your phone can help you remember the correct configuration for reinstallation.
Step 4: Remove Excess Dust with Your Vacuum Cleaner
Take your filters to a well-ventilated area, preferably outdoors, to avoid spreading dust throughout your home. Use your vacuum cleaner with a brush attachment to gently remove loose dust and debris from both sides of each filter.
Work systematically across the entire surface, paying special attention to heavily soiled areas. Don’t press too hard with the brush attachment, as this could damage the filter mesh. Give each filter a good shake afterwards to dislodge any remaining loose particles.

Step 5: Wash Filters in Warm Soapy Water
Fill a large basin or use your kitchen sink with warm water, not hot, as this could damage the filter materials. Add a small amount of mild detergent to create warm, soapy water that’s gentle yet effective for removing stubborn grime.
Submerge the filters completely and allow them to soak for 10-15 minutes. For heavily soiled filters, use a soft brush to gently scrub away accumulated dirt, working in the same direction as the filter fibres to avoid damaging the material.
Step 6: Rinse Thoroughly Under Running Water
After washing, rinse each filter thoroughly under cool running water to remove all soap residue. Ensure you rinse both sides completely, as any remaining detergent could affect air quality when the unit operates. Gently shake off excess water, but avoid wringing or twisting the filters as this could deform their shape and reduce their effectiveness.
Step 7: Ensure Filters Are Completely Dry
Place your clean filters in a well-ventilated area to air dry naturally. Avoid direct sunlight, which can weaken filter materials over time, and never use artificial heat sources like hair dryers or heaters. Depending on humidity levels, drying may take several hours. The filters must be completely dry before reinstallation, as damp filters can promote mould growth and reduce air quality.
Step 8: Clean the Unit and Reinstall Everything
Whilst your filters dry, use a soft cloth to wipe down the air conditioner’s front panel, removing any dust or spider webs that may have accumulated. This prevents contaminants from immediately soiling your clean filters. Once everything is completely dry, carefully reinstall the filters in their original positions, ensuring they fit snugly without gaps. Close the front panel securely and restore power to your air conditioning system.
Keep Your Air Conditioning Running Like New
Establish a Cleaning Schedule That Works
The frequency of cleaning your air conditioner filters will vary depending on several factors.
- In typical Australian homes, filters should be cleaned every two to four weeks during peak usage periods. However, homes with pets, high dust levels, or family members with allergies may need more frequent attention.
- Consider setting a reminder on your phone or calendar to check your filters regularly. A quick visual inspection every fortnight will help you determine if cleaning is needed sooner than scheduled.
- Professional service technicians recommend that homeowners who are uncomfortable performing this maintenance should contact qualified professionals.
- However, regular filter cleaning is cost-effective and well within most people’s capabilities, making it an excellent way to maintain your air conditioning system between professional services.
Remember, clean air filters are just one aspect of air conditioner maintenance. While you can handle filter cleaning yourself, annual professional inspections ensure your entire air conditioning system operates efficiently and safely for years to come.
