Professional Split System Air Conditioner Cleaning

Split system air conditioners are one of the most common cooling solutions in Australian homes and small commercial spaces. Over time, dust, moisture, and contaminants can build up inside the indoor unit, affecting airflow, efficiency, and indoor air quality.

Our technicians provide professional split system air conditioner cleaning services designed to thoroughly clean internal components, support healthier indoor air, and help your system operate efficiently.

Our split system cleaning process is designed to deliver a deep, thorough clean while protecting your home and equipment. This service is recommended for split systems that haven’t been professionally cleaned within the last 12 months.

  • Pre-check and test air conditioner temperature and fans to ensure unit is working.

  • Check surroundings and protect with waterproof tarp.

  • Remove filters and unit cover and take them outside to clean and sanitise.

  • Spray treatment foam which kills mould, bacteria and loosens dirt from coils, drain, fan, fan housing and filters. Leave it for 5-10 min to activate.

  • Using a pressure hose, fully wash the treatment out with clean water.

  • Flush and check the drain to ensure there are no possible leaks.

  • Check fan blades and covers for corrosion and/or grime.

  • Spray the unit with sanitiser and antifungal product to prevent mould and bacteria from regrowing.

  • Reassemble all components, dry excess moisture on or around the aircon unit and test airflow again. Clean and tidy, leaving the area as we found it.

  • Provide a completed next service sticker with recommendation for future aircon high performance.

Signs Your Split System Needs Cleaning

If you notice any of the following, it may be time to book a professional split system clean:

  1. Reduced Airflow or Cooling Performance

    Dust and debris can restrict airflow and reduce cooling effectiveness.

  2. Unpleasant Smells

    Musty or stale odours are often caused by mould or bacteria inside the unit.

  3. Unusual Operating Noises

    Rattling or grinding sounds may indicate internal buildup affecting moving components.

  4. Higher Energy Bills

    A struggling system often uses more energy to maintain the same temperature.

  5. Visible Dust or Mould Around the Unit

    Surface buildup can indicate deeper contamination inside the system.

  6. Water Leaks or Excess Moisture

    Blocked drains can lead to leaks or moisture buildup around the indoor unit.

FAQ

Frequently Asked Questions About Split System Air Conditioner Cleaning

  • What is split system air conditioner cleaning?

    It involves thoroughly cleaning internal components such as filters, coils, fan blades, and drains to remove dirt, bacteria, and mould that affect airflow and air quality.

  • How often should a split system be professionally cleaned?

    Most split systems benefit from professional cleaning once a year, or more frequently in high-use or humid environments.

  • Will cleaning improve cooling performance?

    Yes. Removing internal buildup helps restore airflow and allows the system to cool more efficiently.

  • Why does my split system smell when running?

    Odours are typically caused by mould or bacteria inside the unit or drain. Professional cleaning resolves most smell-related issues.

  • Can I clean my split system myself?

    Basic filter cleaning can be done at home, but professional cleaning is recommended to safely clean internal components and prevent damage.
