Ventilation cleaning is carried out in accordance with the guidelines set down by the HVCA, in their guide to good practice for the cleaning of ventilation systems.

The below guidelines were enforced after the legislation (workplace health and safety and welfare regulations 1992) and the supporting approved code of practice and guidance L24 states that the mechanical ventilation systems )including air conditioning systems) should be regularly and properly cleaned, tested and maintained to ensure that they are kept clean and free from anything which may contaminate the air. This applies to workplaces old and new.
