Safe, compliant and efficient: A Facilities Managers’s guide to grease extraction system cleaning
As a Facilities Manager responsible for large environments such as airports, hospitals, universities, high-rise hospitality venues, or large malls, you know that one of the most overlooked yet critical maintenance areas is the kitchen extraction system.
At National Hood and Duct Cleaning we specialise in commercial hood, duct and flue cleaning across New Zealand. We partner with organisations that demand high standards of compliance, safety, hygiene and risk management.
Why extraction system cleaning matters for big-scale facilities
Efficient and compliant kitchen extraction systems are vital for:
Fire risk reduction. Grease build up in hoods, ducts, fans and flues is a major fire hazard in commercial kitchens and food service facilities.
Health and safety compliance. Facilities teams need to ensure systems are cleaned and maintained to meet the relevant codes and insurance requirements.
Operational efficiency and air quality. A clean fan, duct and hood system improves airflow, reduces strain on HVAC systems, and improves indoor air quality in high occupancy buildings.
Reputation and liability management. In a large facility, a hood or duct issue can impact many stakeholders including tenants, staff, visitors and regulatory inspections.
What Facilities Managers should look for in a cleaning partner
When you oversee multiple sites or high-risk food service areas, choosing the right partner matters. Here’s a criteria you could follow for selecting the right partner:
Nationwide capability and responsive scheduling. We serve Auckland, Hamilton, Tauranga, Wellington and nationwide.
Industry compliance credentials and documentation. We are IQP registered, issue full compliance certificates, and follow industry best practice standards.
Safety, environmental and food-safe focus. We use advanced technology, equipment and environmentally friendly cleaning products.
Scalable and consistent service delivery. For large sites you need a provider who can deliver reliably across all shifts, high ceilings, rooftop fans and complex duct runs.
Transparent reporting and documentation. Facilities Managers often need full visibility on service dates, inspection results and certificates for audit or insurance purposes.
