Ventilation Hygiene & Ductwork Cleanliness Assessment
Green Air Monitoring delivers independent ventilation hygiene assessments to TR19 and CIBSE standards for commercial and public buildings across London and the South East. As non-cleaning auditors, we provide unbiased, objective assessments — unlike companies that both clean and inspect, we have no financial incentive to recommend unnecessary remediation.

Why This Matters
Dirty ductwork and poorly performing HVAC systems are a primary source of poor indoor air quality. TR19 requires periodic assessment of ventilation system cleanliness, and poorly maintained systems can harbour biological contaminants, increase energy costs, and create fire risks.
- TR19 compliance is a legal and insurance requirement
- Contaminated ductwork can spread bacteria and mould spores
- Poor airflow increases CO₂ and reduces occupant comfort
- HVAC inefficiency increases energy consumption by 20–40%
- The Workplace (Health, Safety and Welfare) Regulations 1992 require adequate ventilation in enclosed workplaces
Our Approach
We conduct visual inspection, surface sampling, airflow measurement, and static pressure testing across your HVAC system. Results are reported against TR19, CIBSE, and manufacturer specifications with clear remediation priorities.
