An air conditioning system that smells musty is more than an annoyance; in Townsville’s climate, it’s often a direct indicator of mould contamination circulating through your property. Standard dust cleaning won’t solve it. Our work focuses on the technical decontamination of HVAC systems and ductwork, addressing the specific mould species that thrive in the year-round high humidity of North Queensland.

We operate from our central Townsville base on Sturt St, servicing properties from the coastal suburbs of Pallarenda and Bushland Beach to the inner suburbs of Annandale and Idalia. Our process is built to solve the unique challenges presented by local building styles, from older, high-set Queenslanders in Railway Estate to modern block homes in Douglas.

The Townsville Climate: A Breeding Ground for
HVAC Mould

Townsville’s tropical climate, with humidity averaging over 70% and peaking above 85% during the wet season (November to April), creates ideal conditions for mould growth within HVAC systems. Your air conditioner cools by removing moisture, but that moisture can collect on coils and in ducts, mixing with dust to form a biofilm. This becomes a food source for mould.

We frequently document contamination following significant weather events. After Cyclone Kirrily in January 2024, our team saw a surge in calls related to water ingress and subsequent mould flare-ups in AC units that had been inactive due to power outages.

Our Decontamination Process: Beyond a
Standard Duct Clean

A simple duct clean can spread spores, making the problem worse. Our remediation is a technical process that follows the industry’s highest standards, including the IICRC S520 Standard for Professional Mould Remediation and AIRAH’s HVAC Hygiene best practices.

System Assessment & Diagnostics

We begin with a thorough inspection of the air handler, evaporator coils, and accessible ductwork. We use moisture meters and sometimes recommend ATP surface sampling to quantify the bio-load and identify the moisture source causing the growth.

Containment

We establish critical containment barriers and operate high-volume HEPA-filtered air scrubbers to create negative air pressure. This ensures that mould spores disturbed during the cleaning process are captured and not circulated into other areas of your home or business.

Physical Removal & Cleaning

Using specialized tools, we physically remove mould growth from the evaporator coils, blower fan, and drain pan. Contaminated ductwork is cleaned using controlled methods to prevent cross-contamination. This is not just dust removal; it is a source-removal process.

Post-Remediation Verification

After cleaning, we conduct a final visual inspection and can perform post-remediation air or surface sampling to verify that the system has been returned to a normal fungal ecology. You receive a detailed report of our findings and the work performed.

HVAC & Duct Cleaning FAQs

Why is HVAC mould a specific problem in Townsville?

The combination of prolonged high humidity, heavy use of air conditioning, and periodic extreme weather like cyclones creates a perfect storm for condensation and moisture buildup within dark, dusty ductwork. This is less of an issue in drier climates.

How often does my system need this?

This is not a routine cleaning service. Decontamination is required only when mould contamination has been confirmed. For general HVAC hygiene in coastal suburbs like North Ward or Belgian Gardens where salt air is a factor, an annual inspection is a wise precaution.

Can't I just use a bleach or fogging solution?

No. Fogging and bleaching are not recognized as effective remediation methods by the IICRC because they do not physically remove the mould contamination and can leave behind toxic byproducts. Our process is based on physical source removal.

What's the difference between this and a general AC service?

A general service focuses on mechanical function, like checking refrigerant levels and cleaning filters. Our service is a deep decontamination process focused on removing a biological hazard from the system according to strict environmental health protocols.
