Fresh air in buildings is the key to safe, comfortable and efficient working conditions. An essential factor is that the heating, ventilation and air conditioning (HVAC) ductwork systems must be kept clean. Inevitably all duct systems become fouled over a period of time. The rate and severity of contamination can be attributed to a number of factors. However it is possible to deal with these issues through a sensible programme of hygiene maintenance.

More specifically, Sick Building Syndrome (SBS) is a recognised side effect of indoor, polluted air and is something to be taken very seriously. Workers often complain of a variety of symptoms which may include: headaches, fatigue, loss of concentration, eye and throat irritation, shortness of breath, skin rash, dry skin and itchy skin.

It typically occurs in large open-plan offices with automated heating, ventilation and air-conditioning systems, and invariably where the systems have not been maintained to a satisfactory standard. The results, apart from the possible court action, can be long term illness, staff shortages, and ultimately, major interruption for your business. Besides the effect that it may have on your workforce, a dirty ventilation system is a trap for duct grime and grease etc. This is a severe fire risk.

In short, your ventilation systems need to be cleaned, by a reputable company.
