Mould growth within HVAC systems is a serious concern for commercial and industrial facilities. HVAC mould can compromise indoor air quality, damage system components, and create significant health risks. Once mould is discovered, cleaning is effectively mandatory due to its potential impact on occupant health, building integrity, and regulatory compliance.
Health Risks Associated with HVAC Mould
Mould spores circulated through HVAC systems can trigger respiratory issues, allergic reactions, and exacerbate conditions such as asthma. Prolonged exposure in sensitive environments like healthcare or aged care facilities can lead to severe health complications for both staff and occupants (WHO, 2021).
Regulatory Standards and Compliance
In Australia, the AS/NZS 3666.2:2011 standard specifies the operation and maintenance of air-handling and water systems to control microbial contamination. Additionally, the IICRC S520 standard provides guidelines for professional mould remediation, ensuring safe and effective removal and prevention of recurrence.
Best Practices for HVAC Mould Remediation
Immediate Action and Professional Cleaning: Engage certified professionals to inspect and clean HVAC components, including ducts, coils, and filters. Remediation should be undertaken as soon as mould is identified to prevent spore spread.
Regular Inspections and Maintenance: Routine servicing of HVAC systems helps detect potential mould growth early and maintain compliance with standards.
Moisture Control: Address leaks, condensation, or other sources of excess moisture promptly to inhibit mould proliferation.
Air Filtration: Use high-efficiency filters to capture airborne mould spores and improve overall indoor air quality.
HVAC mould cleaning is not just a maintenance task, it is a critical safety and compliance measure. By following best practices and regulatory standards, facilities can protect occupant health, maintain operational efficiency, and demonstrate a proactive commitment to safety and legal obligations.
