How much does kitchen ventilation maintenance actually cost?

The visible costs 

Most kitchens track direct maintenance costs.These include: 

• Duct cleaning 

• Filter replacement 

• Service visits 

Cleaning is often required multiple times per year. In high-volume kitchens, this can mean quarterly or even monthly service.

Filter replacement adds an ongoing cost, especially in systems exposed to high grease levels. 

The hidden costs

The larger cost is often less visible. 

Energy consumption: 

As filters clog and grease builds up, airflow is restricted. Fans must work harder to maintain performance, increasing energy usage over time. 

Operational disruption 

Cleaning requires planning and coordination. It can involve: 

• Accessing ducts and fans 

• Interrupting kitchen operations 

• Scheduling external service providers 

This affects productivity and daily workflow. 

Labour and administration 

Maintenance requires internal time, including: 

• Managing suppliers 

• Scheduling cleaning 

• Handling compliance requirements 

System wear and lifespan 

Restricted airflow increases strain on system components. Over time, this leads to reduced lifespan, increased risk of failure, and additional repair costs. 

Why costs keep repeating 

Ventilation maintenance follows a predictable cycle: 

• Grease enters the system 

• Performance declines 

• Cleaning is required 

• The system resets 

• Grease enters again 

Each cycle carries cost. In high-volume kitchens, this can happen several times per year. 

What happens when grease is removed at the source 

Most systems manage grease after it has entered the system. A different approach removes grease before it spreads. This changes the cost structure: 

• Less frequent cleaning 

• No filter replacement 

• Stable airflow and energy usage 

Cler uses a filter-free separation process to remove particles directly in the airflow. 

No filters. No buildup. No performance drop. The system runs continuously.
