When was your last documented HVAC system inspection? For many properties, the system that circulates conditioned air is a significant source of indoor contamination. Out of sight, ductwork and air handlers accumulate particulates, mould spores, and bacteria, particularly exacerbated by our subtropical climate. Rapid Restoration provides a documented, standards-led approach to HVAC and air duct cleaning, moving beyond basic cleaning to microbial remediation.
Our technicians are IICRC-certified in Applied Microbial Remediation (AMRT) and follow the NADCA ACR-2021 standard for every project. This isn’t a simple vacuum job. It’s a methodical process of assessment, containment, source removal, and post-remediation verification designed to manage the specific air quality issues faced by properties
Our technicians perform duct cleaning using source removal methods as specified in the NADCA ACR-2021 standard. This involves using powerful negative air machines to create a vacuum within the ductwork, preventing cross-contamination of your home. Agitation tools, such as spinning brushes and air whips, dislodge debris from the interior surfaces of the ducts, which is then pulled directly into a HEPA-filtered collection unit.
A full system cleaning includes all primary components of the air handler. We disassemble and clean the blower motor assembly, fan blades, and housing. These are common points of failure when laden with dirt, which forces the motor to work harder and can lead to overheating. This service is critical for maintaining system efficiency and longevity.
In humid environments, the evaporator coil is a prime location for biofilm and mould development. A dirty coil not only disseminates mould spores but also severely impedes thermal transfer, reducing cooling efficiency and increasing energy consumption. Our process involves applying a non-corrosive coil cleaning agent to break down biofilm and then thoroughly rinsing the coil. We document the condition before and after, showing the restored surface.
Supply vents and return air grilles are cleaned individually. We remove each register, clean it by hand, and clean the duct opening (or “boot”) behind it. This ensures there is no visible contamination left at the point where conditioned air enters your living space.
After all physical contaminants are removed, we can apply an antimicrobial sanitiser. This is particularly important where microbial growth (mould) was identified during the inspection. We use broad-spectrum botanical disinfectant to treat the interior surfaces of the ductwork and air handler. For persistent odours, such as those from long-term mould or previous cigarette smoke, we can perform deodorisation using appropriate technologies.
The air filter is your system’s first line of defence. During our service, we assess the condition and fit of your current filter. Many standard filters are insufficient for capturing smaller particulates like PM2.5 from bushfire smoke. We can recommend and install higher-MERV rated filters or specialised filtration solutions compatible with your specific system, which is a critical step in improving indoor air quality.
For ongoing microbial control, we can install UV-C (ultraviolet germicidal) lights inside your air handler. These lights emit radiation at a wavelength that damages the DNA of microorganisms like bacteria and mould spores, preventing them from reproducing as they pass through the system. This is a common specification for properties with occupants sensitive to allergens or in high-humidity areas.
Our service begins with a comprehensive inspection. Using borescopes and digital cameras, we can access the interior of your ductwork to visually document the level of contamination. We identify any existing issues like disconnected ducts, water intrusion, or damage. You receive a report with images, so you can see the condition of your system before any work begins, a key requirement of the NADCA standard.
For commercial clients and property managers, we offer scheduled maintenance programs designed to meet the requirements of AS/NZS 3666.2. This includes documented inspections of coils, drain pans, and ductwork at specified intervals, providing a clear record of compliance and proactive system hygiene management.
To ensure transparency and verifiable results, we adhere to a strict, multi-step process based on industry best practices.

Our lead technician, who is an IICRC Certified professional, will walk you through the planned scope of work. We protect your home by laying down drop cloths and corner guards where necessary. We then conduct a pre-service inspection, documenting the initial condition with photos.
We connect a high-powered negative air machine with HEPA filtration to the main duct trunk line. This machine runs continuously throughout the process, creating a vacuum to ensure that all dust, debris, and microbes are pulled out of your home and not released into the living space.
We seal all but one of the vents and, working from the furthest point, use agitation tools (such as nylon brushes or compressed air whips) to dislodge all contaminants from the internal duct surfaces. The dislodged debris is pulled directly into the negative air machine. This “source removal” method is the only one recognized by NADCA.
While the ducts are being cleaned, other technicians will be working on the air handler. The blower, coils, and drain pan are cleaned using specialised tools and cleaning agents. This was a critical step in homes we serviced post-flood, where the drain pan had become a breeding ground for mould.
After the cleaning is complete, we conduct a final visual inspection at key access points to ensure the NADCA cleanliness standard has been met. We can show you the “after” photos, providing verifiable proof of a clean system.

Over time, the accumulation of dust, allergens from local grasses and trees, and mould spores becomes a significant contaminant load within the HVAC system. As the system operates, these particles are aerosolized and distributed throughout the living or working space. A thorough, mechanical cleaning removes this source material, directly improving the quality of the indoor environment.
A layer of dust and biofilm on an evaporator coil or blower wheel forces the entire system to work harder to achieve the thermostat setpoint. This restricted airflow and poor thermal transfer leads directly to increased energy consumption. By restoring components to their original clean state, the system can operate at peak design efficiency, often resulting in lower utility costs, especially during Brisbane’s long and humid cooling season.
A clean HVAC system operates under less mechanical strain. Removing the abrasive and corrosive buildup from critical components like motors and coils helps prevent premature failures and costly repairs. Regular system hygiene is a key factor in maximizing the operational lifespan of the equipment, whether it’s in a single-family dwelling or a large commercial facility in the Stapylton industrial area.
