Professional Ducted Air Conditioning Cleaning

Ducted air conditioning systems provide whole-of-property cooling, but because air is circulated through ceiling ducts and vents, internal buildup can affect air quality, airflow, and system performance over time.

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

Ducted systems require specialised cleaning due to their ceiling-mounted components and extensive ductwork. Our structured cleaning process is designed to deliver a deep, effective clean while protecting your property.

  • Pre-check and test ducted air conditioner temperature and vents to ensure the ducted AC unit is working.

  • Check surroundings and protect with a waterproof tarp.

  • Remove filters, filter housing, ceiling outlet and vent covers and take them outside to clean and sanitise with foam air conditioner cleaner and hospital-grade disinfectant.

  • Deodorise ducted air conditioner system.

  • Check the ducted AC system air flow and report any issues to the client.

  • Spray nano fogging treatment through the ducted air supply tubing in the ceiling and return air outlet - which kills mould & bacteria for long-term protection.

  • 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 recommendations for future ducted aircon high performance.

Will came and cleaned the internal part of the aircon today with the Ultimate Cleaning Package (for a deep clean) as it was very mouldy. He was friendly and professional. He even mentioned that he would use Clove Oil, which was helpful communication. That allowed me to decline, as my partner is sensitive to clove oil and it would have been a nightmare if that was put on. The rest of the chemicals are effective and impressive. Thanks Will :) what a great guy. Excellent service, excellent communication, and reasonable price! He had all the right equipment to professionally clean it quickly and efficiently.
