Ventilation System Cleaning

It is well known that the lack of maintenance and cleaning of air conditioning systems is a major cause of staff sickness, contributes to the spread of common infections in the workplace and has been linked to Sick Building Syndrome.

The legal requirements

The Workplace (Health, Safety & Welfare) Regulations require building owners and managers to ensure that enclosed workplaces are ventilated with fresh and purified air and that, where this is provided by a mechanical system, it be regularly maintained, inspected and cleaned and a suitable record kept to support this requirement.

Meeting legal requirements

Our ventilation cleaning service has been designed to assist management meet their legal obligation and exercise their ‘duty of care’. As a first step, we carry out a survey of your system and provide a detailed risk assessment, highlighting issues or defects that impact on the overall cleanliness of the system and benchmarking any accumulated soiling within the system against current industry standards laid down by HVCA TR19 and CIBSE TM26. This will be tantamount to providing an MOT on the state of the system to be included in service records for future use and action.

System cleaning

Where it is found that an air conditioning system needs cleaning we will draw up a set of proposals with costs highlighting particular issues such as installing additional access doors to facilitate thorough cleaning of internal duct surfaces, post-clean reporting and testing. Ductwork cleaning will be carried out with the minimum of disruption and using the latest hygiene methods, in accordance with industry standards.

Cleaning prior to commissioning new or re-furbished systems

In general, the ventilation system is one of the first major services to be installed during a new build, or modified during refurbishment projects, and is prone to contamination from other work such as drilling, carpentry and plastering. CDM regulations require a system to be clean before it is handed over to the client, and it is recommended that it be cleaned prior to commissioning to avoid debris and dirt within the system affecting the commissioning and balancing. Just ask us to survey and provide quotations at the planning stage.
