How often should exhaust fans and ducts be cleaned?

Most commercial kitchens benefit from professional cleaning every 6–12 months, depending on cooking volume and grease build-up.

Why is exhaust fan cleaning important?

Exhaust fans remove grease, smoke, and fumes. Over time, grease builds up and can cause overheating, fire hazards, and equipment failure.

Do you provide certification?

Yes. Big Ben Cleaning Services issues a Certificate of Completion for all exhaust fan and duct cleaning, ensuring compliance with AS 1851.6:2012.

Can you clean areas other companies can’t reach?

Absolutely. If needed, we install access panels to reach all ducting and fan components — ensuring a thorough, compliant clean.

What’s included in a professional kitchen duct clean?

Professional, Thorough Exhaust Fan & Duct Cleaning

A kitchen’s exhaust system does a lot of heavy lifting. From removing heat and smoke to controlling odours and airborne grease, it plays an essential role in keeping the workspace safe.

Grease, dust and debris build up inside every kitchen exhaust fan cleaning system and ducting and when this happens, airflow is reduced, odours linger and the risk of fire increases significantly.

At Big Ben Cleaning Services, we specialise in expert commercial exhaust fan cleaning and full kitchen exhaust duct cleaning services across Australia. Our trained technicians clean every part of your system, including internal ductwork, ensuring your kitchen remains hygienic and compliant with Australian Standard AS 1851.6:2012.

If you need a routine kitchen exhaust fan cleaning service or a full commercial exhaust system cleaning, we deliver reliable, certified results every time.
