In Melbourne’s booming food scene, keeping your kitchen cool isn’t just about comfort—it’s about compliance. From sizzling woks in Chinatown to slow-cooked brisket in Brunswick, greasy air and moisture can wreak havoc on your split system air conditioning.
Poor AC hygiene doesn’t only cause odours or higher power bills—it can put you on the wrong side of local health expectations if exhaust and AC systems aren’t cleaned regularly.

Why It Matters: Melbourne Kitchens Under Pressure
Melbourne’s food culture is world-class, and expectations are high. Ventilation and air conditioning in food premises should be maintained in a hygienic condition—free from grease, grime, mould and airborne food particles—and operated so they don’t contaminate prep areas.
- Maintain AC/ventilation in a hygienic state
- Prevent grease and mould build-up
- Operate safely without contaminating food zones
This includes split system AC units near prep or service areas—not just the big stainless-steel range hoods.
- Mould spores drifting into food service
- Bad odours in the dining space
- Grease reducing AC performance
- Headaches during council spot checks
How It Works: Hidden Grime in Plain Sight
In kitchens, AC deals with humidity, airborne grease and microscopic food particles. Over time, build-up happens inside your split system:
- Filters: Lint, grease and smoke residue clog the mesh
- Evaporator coils: Sticky film slows heat transfer
- Drain pans: Slime and bacteria start colonies
- Fans: Draggy airflow = poor cooling and smells
Monthly wipe-downs aren’t enough. Plan routine deep cleans—especially in busy kitchens.
