WHY CLEAN VENTS?

There is growing concern over the quality of the air we breathe, and for most of us that means a long period of time breathing air supplied to us through air conditioning systems and vents.

If you inspect any air conditioning system after three or four years you will invariably find debris somewhere in the system.  It may just be a light dust build-up but it is there, and the air that you breathe passes through or over it.  Add to this the worst situation of vermin decaying in the ductwork and then the added incidence of damp, and you will have the perfect scenario for the war of bacteria.  Yeasts and fungi will grow and multiply and you will breathe it in.

All these situations can arise over years by natural neglect i.e. filters wrongly specified or size changed, frequently missing vermin screens from intakes, badly maintained fan units causing vibration and noise, natural degradation of insulation material (used internally on some ducts) and certainly in acoustic silencers allow excess fibres to migrate into the system.  All of this is just the supply system.

Extract systems tend to be neglected as it is being sucked out of the building, but this gets contaminated with fibres, working materials, dead skin and many other types of contamination just from your office.

The following chart shows some of the problem bacteria and viruses associated with air conditioning that haven't had proper ventilation cleaning.

WHILE IT IS POSSIBLE FOR THE LIST BELOW TO BE FOUND IN SYSTEMS, IN HARMFUL QUANTITIES IT IS IN FACT RARE.  HOWEVER, REGULAR CLEANING
AND SANITIZING WILL PREVENT THIS.
