AIR CONDITIONING DUCT WORK CLEANING
It is recommended by the Australian Standards’ AS3666.2 that all ductwork be cleaned prior to commissioning but unfortunately this is rarely carried out. This means that over the years, more dust and dirt builds up added to the building debris that is usually left in ducting on completion of building work. This is the ideal breeding ground for bacteria and mould growth.
KITCHEN EXHAUST CLEANING
The Fire Act requires kitchen exhaust systems be cleaned at least every 12 months, while AIRAH guidelines recommend that all parts of the canopy and ductwork be checked monthly and cleaned if necessary. It is vital that you check with your insurance company as to what their policy is as some companies require hood cleaning be carried out at more frequent intervals than every 12 months. Filters should be cleaned as often as necessary.
PLANT ROOM CLEANS
Our normal procedure for cleaning plant rooms is to clean the externals of the AHUs, but this may have been carried out with the AHU clean. The walls, ceiling and floors of the Plant Room are cleaned, deodorised and disinfected with all debris removed from site.
CAR PARK EXHAUST CLEANING & GENERAL EXHAUSTS
Car park supply and exhaust ducts definitely need cleaning more often that air conditioning ductwork due to particulate build up from vehicle exhausts, especially in confined spaces with heavy traffic volumes. Recommendations for these exhausts are the same as air conditioning ducting, but we have found that a lot of car park ducting requires cleaning at yearly intervals.
AIR HANDLING UNIT (AHU) AND PLANT ROOM CLEANING
It is recommended in AS3666.2 and according to AIRAH guidelines that all AHUs be inspected monthly with particular attention to drain trays. The units should be cleaned at least yearly, but if monthly inspections show any problems then the units should be cleaned as required.
There is an old saying ‘An ounce (gram) of prevention is worth a pound (kilo) of cure’ and this is particularly true when it comes to your air conditioning and exhaust systems. We can help you protect your systems with the following suggestions
