Melbourne’s kitchen exhaust & HVAC cleaning specialists

Although Australian Standard AS 3666.2 details that HVAC ducts and coils should be inspected monthly, in practice this is not always necessary. A professional HVAC cleaning company like Clean Air Filtration will advise how often your ducts should be inspected to comply with the standard.

AS 3666.2 specifies that ducts and coils are cleaned “when necessary”. In practice, for most systems, this is at least once per year.

Australian Standard AS 1851 states that canopies and exhausts should be cleaned at least once every 12 months. Best practice is often more frequent, depending on the fuel (solid or non-solid), the food cooked and how often you cook. A better guide: clean when grease build-up exceeds 0.2 mm on average across the system, or 2 mm in any one spot.

The primary reason is to prevent a kitchen fire, but there are five more: compliance (non-compliance with AS 1851 can lead to fines); odours (grease breeds mould and bacteria); pests (grease and mould attract rats and mice); health (grease and bacteria near food preparation can cause sickness); and equipment life (clean canopies, fans and ducts run efficiently and break down less).
