But how clean are the ducts, directly behind these vents, that move the air around the building? “What you can’t see from the outside is the accumulated dust, particulates, bacteria, fungus and mould in the ductwork that can lead to contaminated air and fire hazards,” explains Jason Mittenzwei, Airgene’s Operations Manager. “This build up also affects the air conditioning equipment, affecting its performance and energy efficiency.” Quite often, it’s not until a system breaks down, there’s odour or a run of illness in the office that the real source of the problem is uncovered. “Diligent office cleaners could actually be giving you a false sense of security…just because you can’t see it, doesn’t mean it’s not there,” Jason continues. “You would be amazed what some ducts look like when we take the vents off – you realise it’s no wonder the employees were uncomfortable!” Airgene ensures that all ductwork, supply, return and outside air, bathroom and laundry exhausts are inspected and remediated according to AZ.NZS 3666, AS1851 and NFPA90A.
