What Builds Up Inside Your Air Conditioner

Every time your air conditioner runs, air passes over the filter, the coils and the fan barrel. Dust, pet dander and moisture collect there, and in Sydney’s humidity that combination is where mould takes hold. Because the same air is pushed straight back into the room, whatever is sitting inside the unit travels with it.

  • Mould and mildew on the fan barrel, coils and drip tray
  • Dust and pet dander packed into the filters
  • Bacteria in the standing moisture of a blocked drain line
  • Musty odours that come back within minutes of switching the unit on

What Happens When Your Aircon Is Not Cleaned?

Air conditioners collect dust, grime and moisture over time. If your unit smells musty, looks dirty or is not moving air as well as it used to, it may be ready for a professional clean.

  • Musty smells when the unit starts. Moisture and grime can build up around filters, coils and the fan barrel.
  • The system works harder than it should. Dirty filters and coils can restrict airflow and reduce operating efficiency.
  • Dust returns soon after cleaning. Built-up dust inside the unit can continue circulating while the aircon runs.
  • Airflow feels weaker. A professional deep clean can remove the buildup obstructing internal components.
  • The unit is noisier than usual. Heavy buildup around moving parts may affect how smoothly the system operates.

What Changes After a Deep Clean

A professional deep clean removes the buildup inside key components. Results vary by unit, but these are some of the improvements customers commonly notice.

  • Stronger, cleaner airflow. With the filter, coils and fan barrel clear, air moves through the unit without fighting a layer of buildup.
  • The musty smell goes. Because the mould and grime causing it are physically removed, not masked.
  • Fresher air for the whole family. The dust, dander and mould sitting in the airflow path are taken out of it.
  • A unit that works less hard. A system that isn’t pushing air through blockage draws less power to reach the same temperature.
  • A longer service life. Less strain on the fan and compressor, and small faults spotted before they become failures.

Aircon Cleaning FAQs

A split system deep clean is $249 + GST, a ducted system starts from $350 + GST, and an outdoor condenser unit is $149 + GST. The price is fixed and confirmed before we start, so you know exactly what the job costs before anyone touches your unit.

We clean the filters, evaporator coil, barrel fan, drain pan and drain line, then sanitise the unit and test it before we leave. The unit is taken apart properly rather than wiped over, because the mould and bacteria sit on parts you cannot reach from the front.

Once every 12 months suits most Sydney homes. Move to every six months if you have pets, if someone in the house has asthma or allergies, or if the unit runs most of the year. Rinsing the filters yourself between services helps in the meantime.

Usually, yes. That smell comes from mould and bacteria growing on the evaporator coil and in the drain pan, where moisture sits. A deep clean removes the growth rather than covering it, so the smell goes instead of returning a fortnight later.

Yes, as a separate service at $149 + GST, because it is a different job. The outdoor condenser collects leaves, dust and grass clippings, which makes the whole system work harder. Plenty of customers book it at the same time as the indoor clean.

Yes. We use eco-friendly, non-toxic products throughout, and the unit is rinsed and dried before we hand it back. There is no lingering chemical smell and the room can be used straight away.

Yes, we provide emergency cleaning services for air conditioning to help you during urgent situations. Contact us anytime for immediate assistance.

You can request a quote using our online form or by giving us a call. One of our team members will respond promptly to provide you with the necessary information.
