Why You Should Regularly Service Your Cooker Hoods and Kitchen Extractor Systems

Whether you’re managing a bustling commercial kitchen or cooking for your family at home, keeping your cooker hood and extractor system in top condition is not just a matter of hygiene—it’s a matter of safety, efficiency and cost-effectiveness.

What Does a Cooker Hood or Extractor Fan Do?

Cooker hoods and extractor fans are designed to remove airborne grease, smoke, odours, and steam produced during cooking. 

They help maintain air quality and reduce the build-up of moisture and contaminants in your kitchen. But these hardworking appliances only function properly if they are regularly cleaned and maintained.

Why Regular Servicing Is Essential

1. Fire Safety

Grease and oil build up quickly inside extractor systems, especially in commercial kitchens where cooking is constant. This build-up can become a serious fire hazard. Regular servicing ensures that these residues are removed before they reach dangerous levels.

2. Improved Air Quality

Blocked or dirty filters reduce the efficiency of extraction, leaving smoke, odours and even harmful airborne particles lingering in your kitchen. Clean filters and a well-maintained system help keep the air fresh and breathable.

3. Better Energy Efficiency

When filters are clogged or the system is struggling to perform, it must work harder—using more energy and increasing your utility bills. A clean, well-functioning extractor is more efficient and environmentally friendly.

4. Extended Appliance Life

Just like any mechanical system, regular maintenance helps prevent wear and tear. Neglecting to clean and service your extractor can lead to expensive repairs or the need for a full replacement much sooner than expected.

5. Hygiene Compliance in Commercial Kitchens

For food businesses, keeping extractor systems clean is a legal requirement under health and safety regulations. Failure to do so can result in hefty fines, forced closures, or failing hygiene inspections. Regular servicing and proper documentation are essential for compliance.

How Often Should You Service and Change Filters?

Domestic Kitchens: Replace or clean filters every 3–6 months, depending on usage. A full service is recommended annually.

Commercial Kitchens: Filters should be cleaned weekly or monthly, and professional servicing should be carried out at least every 6 months—more frequently if you operate a high-volume kitchen.

Signs Your System Needs Attention

Reduced suction power or poor odour control

Excessive noise or rattling

Visible grease build-up

Smell of burning or overheating

Lights or control panels not functioning correctly

Final Thoughts

Your cooker hood and extractor system are not ‘fit and forget’ appliances. They require regular attention to function effectively and safely. Whether you're at home or in a commercial environment, staying on top of maintenance will save you money, reduce risk, and ensure a healthier kitchen for everyone.

Bonus Tip: Keep a Maintenance Log

In commercial settings, maintaining a log of filter changes and servicing dates helps demonstrate due diligence to health inspectors and insurance providers.
