Professional Split System AC Cleaning Across South East Queensland

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.

How Do You Know When 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

Split System Air Conditioner Cleaning: Your Questions Answered

  • What is split system air conditioner cleaning?

    Split system air conditioner cleaning is a professional service that thoroughly cleans all internal components of your indoor AC unit — including the filters, evaporator coil, blower fan, drain tray and drain pan — removing the accumulated dust, mould and bacteria that affect performance and air quality.

    Unlike basic filter cleaning you can do yourself, a professional service involves dismantling the unit casing, high-pressure cleaning the coil and fan assembly, sanitising the drain tray, and treating internal surfaces with an antibacterial agent. This reaches the areas that a cloth or vacuum simply can't access.

    The result is improved airflow, better cooling efficiency, reduced energy consumption and cleaner air circulating through your home. Most customers also notice a significant improvement in odour after the service.

    The 99 People offer three tiers of split system cleaning — from a Standard Basic clean to the Ultimate Platinum Air Wellness Restoration — all available across Brisbane, Ipswich, Gold Coast, Sunshine Coast and Noosa from just $99.

  • How often should a split system be professionally cleaned?

    For most South East Queensland homes, a professional split system clean once a year is the minimum recommended — but many households benefit from cleaning every six months, particularly during heavy-use periods in summer.

    Queensland's warm, humid climate accelerates the growth of mould and bacteria inside AC units compared to cooler states. A split system running daily through a Queensland summer can accumulate significant internal buildup within a single season, reducing airflow and driving up energy costs.

    As a general guide: if your split system runs for more than four hours a day through summer, book a professional clean every six months. If it runs occasionally or mainly for heating in winter, annual cleaning is usually adequate. If you've noticed reduced airflow, an unusual smell or higher power bills, those are signs it needs attention sooner.

    The 99 People offer same-day bookings across SEQ — so you don't need to wait weeks for an appointment. Book online or call 1300 099 778.

  • Will cleaning improve cooling performance?

    In most cases, yes — and often significantly. The most common cause of poor cooling in a split system is a buildup of dust and grime on the evaporator coil. When the coil is coated, it can't absorb heat from the room air efficiently, so the system runs longer to reach the set temperature and still doesn't cool as well as it should.

    A professional clean removes this buildup from the coil, blower fan and filters, which directly restores the system's ability to absorb heat and push cool air. Most customers notice an immediate improvement in airflow and cooling after the service.

    If the system still underperforms after a thorough professional clean, the issue is more likely with refrigerant levels or a mechanical component — which a technician can diagnose during the visit.

  • Why does my split system smell when running?

    A musty or stale smell from your split system is almost always mould and bacteria growing inside the unit — typically on the evaporator coil, in the drain tray, or on the filters. In Queensland's humidity, these conditions develop quickly inside any AC unit that isn't regularly cleaned. When the fan runs, it pushes air through this contaminated area and carries the smell into your room.

    Other common smell types: a burning smell can indicate dust on the heating element (usually harmless and clears after a short time in heating mode), a sweet chemical smell may indicate refrigerant leakage (requires urgent attention), and a dirty sock or gym-locker smell is the classic signature of mould on the coil.

    Professional cleaning removes the source of the smell — not just mask it. The 99 People's Ultimate Platinum service also includes AirGuard Nano mould protection, which helps prevent mould regrowth between annual cleans. Most smell issues are fully resolved in a single visit

  • Can I clean my split system myself?

    You can clean the air filters yourself — and you should, every four to six weeks. Slide the filters out, rinse them under warm water, let them dry completely, and reinstall them. This basic maintenance between professional services helps maintain airflow and is safe to do at home.

    Beyond the filters, professional cleaning is strongly recommended. The evaporator coil, blower fan, drain tray and internal casing require dismantling the front panel and using appropriate cleaning agents and equipment. Incorrect cleaning can damage delicate coil fins, push mould further into the unit, or cause water to enter electrical components.

    There's also the safety aspect: split systems run on 240V electricity, and working inside the unit without isolating the power is a risk not worth taking for most homeowners.

    For everything beyond the filters, leave it to a licensed technician. The 99 People's standard service covers all internal components from $99.
