Air Handling System Monitoring and Deep Cleaning

Industry guidelines state that air ducting and ventilation systems should be cleaned on a regular basis, as high levels of dust moving through the systems can affect the air quality in your premises.

Rentokil Specialist Hygiene can monitor the dust and hygiene levels in your systems and provided a TR19 compliant report. We also offer air handling system deep cleaning solutions.

Did you know?

TR19 guidelines explain that under The Workplace (Health, Safety & Welfare) Regulations, it is a legal obligation for managers and building owners to ensure that enclosed workplaces are ventilated with fresh, purified air.

Therefore, it is advised that heating ventilation and air conditioning (HVAC) systems are cleaned regularly to remove any dirt or dust that can build up and cause potentially harmful bacteria to be spread throughout the air management system, which could increase the spread of illness in your premises. A system that is compliant with the TR19 standards is more likely to ventilate fresh air.
