Critical Care: HVAC Hygiene in Healthcare Environments
Healthcare environments demand strict IAQ and infection control — airborne mould, bacteria, and bioaerosols can all lead to hospital-acquired infections.

Healthcare Sector – HVAC Hygiene & IAQ Challenges
Healthcare facilities operate under strict indoor air quality and infection control requirements. Airborne mould, bacteria, and bioaerosols present real risks, contributing to hospital-acquired infections and impacting patient and staff safety. With sensitive clinical areas and 24/7 operation, hospitals require specialised HVAC hygiene practices.
A key part of any hospital HVAC project is maintaining safe, controlled cleaning conditions. This includes proper containment barriers, continuous negative pressurisation with HEPA-filtered extraction, and mobile biohazard enclosures for any ceiling or out-of-duct access. Larger containment zones are established for more extensive works.
Containment also extends above ceilings and inside ductwork to prevent cross-contamination and ensure the hospital environment remains protected throughout the process.
HVAC Hygiene Services for Hospitals


HVAC and Duct Cleaning for Hospitals
We provide cleaning in accordance with AS/NZS 3666 and AS 1851, both referenced in Workplace Health & Safety requirements, the QLD Work Health and Safety Act 2011, and the Work Environment and Facilities Code of Practice 2011.
Our hospital HVAC hygiene services include:
- Supply, return and exhaust grille cleaning
- Coil cleaning (evaporator & condenser)
- Ductwork and riser cleaning
- Split-system cleaning
- Duct sealing (Aeroseal)
- Antimicrobial coating application
- Plant room and AHU hygiene
- Drain pan, drain line and filtration cleaning
- Negative pressure cleaning with HEPA extraction
- UVC system installation and maintenance


Kitchen Exhaust Cleaning for Hospitals
Clean-Air Australia follows stringent processes aligned with AS 1851-2012, manufacturer cleaning requirements, and the specific usage patterns of each kitchen the exhaust system serves.
Our kitchen exhaust hygiene services include:
- Full kitchen exhaust system cleaning (hood, plenum, riser, fan)
- Filter and grease-trap cleaning
- Fan and motor cleaning
- Access panel installation for compliant maintenance
- Grease removal from ductwork and hard-to-reach sections
- Fire-risk reduction treatments
- Compliance reporting with photo documentation


Dryer Vent / Laundry Exhaust Cleaning for Hospitals
For preventative maintenance and fire risk reduction, commercial dryers in hospitals and aged care facilities—often running for most of the day—require scheduled laundry exhaust cleaning to remain safe and efficient.
Our dryer vent & laundry exhaust services include:
- Full dryer duct and exhaust cleaning
- Removal of lint, debris and airflow blockages
- Cleaning of booster fans, lint collectors and termination points
- Inspection of duct integrity and airflow performance
- Fire-risk mitigation through routine maintenance
- Compliance reporting with before-and-after documentation
Infection Control (IFC)Measures for Hospitals

Containment Measures
We establish strict containment zones to prevent cross-contamination during HVAC hygiene works. This includes mobile biohazard enclosures, fixed barriers for larger areas, and continuous negative pressurisation supported by HEPA-filtered extraction.

Advanced Chemistry Cleaners
We use hospital-grade probiotic and enzymatic cleaners to break down organic contaminants at the source. Surface-shield antimicrobial treatments provide up to 12 months’ protection on HVAC finishes such as grilles and hardware. (Clean-Air is an Aeris Environmental Platinum Partner.)

UVC Installation
UVC germicidal technology is integrated into HVAC systems to continuously disrupt microbial DNA, reducing airborne pathogens and lowering surface contamination in high-risk areas.

Permanent Antimicrobial Coatings
Long-lasting antimicrobial coatings are applied inside ductwork to inhibit future microbial growth, improving system hygiene between maintenance cycles.

Indoor Air Quality & Surface Testing
We support infection control compliance with targeted testing methods—swab samples, lift-tape analysis and cassette air captures—to monitor microbial loads and validate cleaning effectiveness.
Infection Control Dashboard
We created the Infection Control Dashboard to illustrate the shared roles and responsibilities of key stakeholders within the broader infection control landscape in hospitals and healthcare environments.
