Heating, ventilation, and air conditioning (HVCA) all use Duct systems to deliver and remove air and regular air duct cleaning is important to maintaining the indoor quality of the air in any large building, where large numbers of people work, study or live.

Temperature control can also be an issue because people to not perform at their peak, either in the schoolroom or lecture room, or in the workplace, if the air is stuffy or too warm.

In any building where people are frail or may have a weakened immune system, such as residential homes for the elderly and hospitals and indeed poor air quality has been indicated in situations of sick building syndrome in addition as the control of airborne infections air quality is important.

where toxic chemicals need to be removed from the air of the laboratory or the workplace the efficiency of an air duct system could make the difference between life and death.

In the UK the Health and Safety Executive and the COSHH (Control of Substances Hazardous to Health) both have an interest in maintaining the quality and safety of air in buildings.

One of the main problems of maintaining the hygiene and efficiency of any heating or ventilation system that relies on air ducts is whether the system has enough access points.

If the system was installed some years ago it is likely that it no longer meets modern advisory standards, which have been detailed by HVCA (Heating and Ventilating Contractors’ Association).

Equally the building may have been changed, extended or otherwise additional to over the years and again this can complicate access to the existing ventilation ducting system.

If an organisation is using its own maintenance team to take care of ductwork cleaning the employer has a duty of care to ensure that the work can be carried out safely and using the proper equipment, and again this can be difficult to unprotected to when the access to the ductwork is less than adequate.

Regular maintenance and duct cleaning should be a part of any building maintenance programme. It is not only important for prevention of fire risk, possible ill health of employees but also because a well-maintained system will function efficiently to keep energy costs as low as possible.

Many specialist commercial cleaning companies offer an initial free survey and checking service and will advise not only how frequently the system should be cleaned, filters checked and replaced, but also whether access to ductwork can be improved.

If it should prove that access is an issue they also offer a service to install additional access points, which if carried out should consequence in less time having to be spent on future occasions for cleaning and maintenance.
