Airports & Transport Hubs – HVAC Hygiene & Public Health Challenges
Airports, rail terminals, and transport hubs operate continuously, accommodating large passenger volumes in complex, high-traffic environments. These facilities face unique indoor air quality challenges, including elevated dust loads, moisture ingress, mould growth, and contamination across HVAC systems, soft furnishings, and public areas.
Maintenance works must be meticulously planned, security-cleared, and delivered without disrupting operations or passenger flow. Clean-Air provides fully coordinated HVAC hygiene and environmental cleaning services, delivered by ASIC-cleared, NADCA- and IICRC-certified technicians, with proven experience working airside, landside, and within secure operational zones.
Our structured approach improves air quality, protects assets, and supports safe, comfortable environments across terminals, concourses, lounges, offices, and back-of-house spaces.
HVAC Hygiene & Environmental Services for Airports and Transport Hubs
AHU & Duct Cleaning for Transport Facilities
Large-scale HVAC systems serving terminals and transport hubs require regular hygiene maintenance to maintain airflow, control contamination, and meet public-health expectations.
Our services include:
- Complete AHU cleaning (coils, fans, housings, and filtration sections)
- Supply, return, and exhaust duct cleaning
- Riser, shaft, and ceiling-void ductwork cleaning
- HEPA-filtered negative pressure extraction
- Compliance-aligned reporting with photographic documentation
- Aeroseal® Duct Sealing to meet airtightness standards of less than 5% leakage

Flexible Duct Replacement & Diffuser Cleaning
Ageing or damaged flexible ducting can shed fibres, restrict airflow, and harbour contaminants. Clean-Air replaces flexible ducting in accordance with IICRC and NADCA standards to maintain system integrity and performance.
Our services include:
- Flexible duct removal and compliant replacement
- Diffuser, grille, and cushion box cleaning
- AerisGuard BioActive Surface Treatment applied to diffusers and boxes
- Bio-static protection providing up to 12 months’ resistance to microbial growth
- Improved airflow consistency and air quality
Mould, Soft Furnishings & Kitchen Exhaust Hygiene
High passenger volumes, humidity, and food service areas increase the risk of mould growth and contamination beyond HVAC systems.
Our environmental hygiene services include:
- Mould remediation for HVAC systems, carpets, and soft furnishings
- Antimicrobial treatment of porous and non-porous surfaces
- Commercial kitchen exhaust cleaning (hoods, ductwork, fans)
- Fire-risk reduction and grease-load management
- Compliance reporting with before-and-after documentation

Critical Hygiene Considerations for Airports & Transport Hubs
Security & Access Compliance
Our technicians hold relevant security clearances, including ASIC passes, and operate within strict airport and transport security protocols.
Aeris Antimicrobial Coatings
Fibreglass-lined ductwork is treated with Aeris antimicrobial coatings to seal internal surfaces, prevent fibre fraying, inhibit mould, mildew, and bacterial growth, and minimise insulation fallout.
Diffuser & Cushion Box Protection
Diffusers and cushion boxes are treated with AerisGuard™ BioActive Surface Treatment, providing up to 12 months of ongoing microbial protection in high-traffic public areas.
Minimal Disruption Works
All works are staged, contained, and coordinated to maintain passenger movement and operational continuity.
Public Health & Comfort
Improved HVAC hygiene supports cleaner air, reduced odours, and enhanced comfort for passengers and staff.
