Why do I need to clean my restaurant hood exhaust system?

To remove accumulated fuel (grease deposits) and prevent spontaneous combustion and fire in your hood exhaust system. This includes cleaning the hood, filters, plenum, ducts and fans (entire system).

Why can’t my employees clean my kitchen’s hood exhaust system?

Restaurant hood exhaust system cleaning requires special tools, equipment and expertise to properly and thoroughly clean the hard to access systems. Trained technicians also know how to work safely in your kitchen’s grease laden environment. NFPA 96 states that “the entire exhaust system shall be cleaned by a properly trained, qualified and certified company or persons.” Local codes often require a trained and certified company.

How often do I need to clean my kitchen’s hood exhaust system?

Each local municipality has a fire code to guide maintenance of your hood exhaust system. Municipalities often refer to NFPA 96 Guidelines (National Fire Protection Association) for their own requirements.

The NFPA 96, 2011 Standard—Table 11.4 recommendations are:

Solid Fuel (wood, charcoal) Monthly
High-volume, 24 hours ops. Quarterly
Moderate volume Semi-annually
Low-volume (camps, churches) Annually

How long does it take to clean, service, and inspect my Kitchen Exhaust Hood System?

Generally, a service can be completed in approximately 2-3 Hrs. However, depending on the size and condition of your vent hoods, services may take longer.

Will my restaurant need to be closed during the time of cleaning?

Yes. In order to properly service your kitchen exhaust hoods, all cook line equipment must be turned off and properly shrouded.
