A commercial range hood works continuously to remove smoke, grease, heat, steam and cooking odours from busy kitchens.

Restaurants, cafés, takeaway shops and other commercial kitchens in Melbourne can produce large amounts of grease-laden vapour. Without suitable cleaning, inspection and maintenance, grease can accumulate in filters, canopies, ductwork and exhaust fans.

Regular commercial range hood maintenance helps keep the ventilation system operating effectively and can reduce the risk of unexpected repairs.

Why Commercial Range Hood Maintenance Matters

A properly maintained commercial range hood can help:

• Maintain suitable airflow

• Reduce grease accumulation

• Control kitchen heat and cooking fumes

• Support a cleaner kitchen environment

• Reduce the risk associated with grease accumulation

• Identify mechanical problems early

• Extend the service life of exhaust components

Maintenance requirements vary between kitchens, so the cleaning and servicing schedule should reflect the type and volume of cooking.

What Parts of a Commercial Range Hood Need Maintenance?

A commercial kitchen exhaust system contains several components that need regular attention.

Grease Filters

Grease filters capture particles from cooking vapours before the air moves through the exhaust system.

Dirty filters can restrict airflow and reduce extraction performance.

Filters should be cleaned at suitable intervals based on kitchen usage and the requirements of the equipment.

Exhaust Canopy

The stainless steel canopy can collect grease, cooking residue and other contaminants.

Regular cleaning helps maintain hygiene and keeps the canopy in good condition.

For a new or custom system, see our commercial exhaust canopy Melbourne service.

Exhaust Ductwork

Grease can accumulate inside exhaust ductwork over time.

Ductwork should be inspected and cleaned as required for the cooking operation and ventilation system.

CGC Stainless Steel also provides commercial exhaust duct fabrication Melbourne for commercial kitchen projects.

Exhaust Fan

The exhaust fan plays an important role in moving contaminated air through the ventilation system.

Unusual noise, vibration or reduced extraction may indicate that the fan or another part of the system requires inspection.

Airflow

Suitable airflow is essential for effective kitchen ventilation.

If smoke, heat or cooking odours remain inside the kitchen, the ventilation system may need to be inspected.

Common Commercial Range Hood Problems

Poor maintenance can contribute to several problems.

Reduced Airflow

Grease-loaded filters and restricted components can affect extraction performance.

If smoke remains around the cooking equipment, check the filters and arrange an inspection if required.

Grease Build-Up

Grease can accumulate on filters, canopy surfaces, ductwork and exhaust components.

For more information, read what causes grease build-up in commercial range hoods.

Strong Cooking Odours

Persistent cooking smells can indicate restricted extraction, dirty filters or another ventilation issue.

Excessive Kitchen Heat

If heat is not being removed effectively, the kitchen can become uncomfortable for staff.

Unusual Fan Noise

A sudden change in exhaust fan noise may indicate a mechanical issue that needs attention.

How Often Should a Commercial Range Hood Be Cleaned?

There is no single cleaning schedule suitable for every commercial kitchen.

The appropriate frequency depends on:

• Type of cooking

• Amount of grease produced

• Number of hours the kitchen operates

• Cooking volume

• Exhaust system design

• Equipment used

A kitchen using deep fryers, chargrills or wok cooking may require more frequent cleaning than a lower-volume café.

Instead of applying the same schedule to every business, establish a maintenance program based on the actual cooking operation.

Commercial Range Hood Cleaning Checklist

A regular maintenance program can include:

• Cleaning grease filters

• Cleaning accessible canopy surfaces

• Checking for grease accumulation

• Inspecting exhaust fans

• Checking ductwork

• Monitoring airflow

• Checking unusual fan noise or vibration

• Inspecting exhaust components

• Recording cleaning and servicing

• Arranging repairs when required

How to Clean Commercial Range Hood Filters

Grease filters should be cleaned regularly according to the equipment requirements and kitchen workload.

A basic cleaning process may include:

1. Switch off the relevant equipment and allow components to cool.

2. Remove the filters according to the manufacturer’s instructions.

3. Remove accumulated grease and residue.

4. Clean the filters using a suitable cleaning method.

5. Allow filters to dry properly.

6. Reinstall the filters correctly.

7. Check that airflow remains suitable.

Heavily contaminated or damaged filters may need professional attention or replacement.

How to Reduce Grease Build-Up

Commercial kitchens can reduce excessive grease accumulation by:

• Cleaning filters regularly

• Cleaning canopy surfaces

• Maintaining suitable extraction

• Monitoring grease accumulation

• Keeping exhaust components accessible for maintenance

• Arranging duct inspection and cleaning when required

• Addressing ventilation problems promptly

Good daily kitchen practices also help reduce the amount of grease that enters the exhaust system.

Signs Your Commercial Range Hood Needs Servicing

Watch for these warning signs:

Smoke Remains in the Kitchen

If smoke is no longer being captured effectively, the exhaust system should be checked.

Filters Become Dirty Quickly

Rapid grease accumulation may indicate heavy cooking loads or a need for more frequent cleaning.

Strong Odours Remain

Persistent cooking odours may indicate restricted or inadequate extraction.

Fan Performance Changes

Unusual sounds, vibration or reduced airflow can indicate a mechanical problem.

Grease Is Visible Around the System

Visible grease on the canopy, filters or accessible exhaust components indicates that cleaning is required.

Kitchen Temperatures Increase

Poor extraction can contribute to excessive heat around the cooking area.
