Introduction

A clean and well-maintained exhaust system is the backbone of every commercial kitchen. It keeps the air fresh, removes smoke and grease particles, and ensures a safe cooking environment. However, one of the most common questions restaurant owners have is how often they should schedule exhaust cleaning. The answer depends on the type of cooking, the volume of food prepared, and the equipment used.

Why Regular Exhaust Cleaning Matters

Over time, grease and residue build up in the ducts, hoods, and fans. If left unchecked, this buildup can reduce airflow, affect system performance, and increase the risk of fire. Routine cleaning not only protects your equipment but also keeps your restaurant compliant with NFPA 96 standards and local fire safety regulations.

Recommended Cleaning Frequency

The National Fire Protection Association (NFPA) provides general guidelines for how often exhaust systems should be cleaned based on the type of cooking operation:

  • High-volume kitchens such as 24-hour diners, fast food restaurants, or establishments with wood or charcoal cooking should schedule cleaning every three months.
  • Moderate-volume kitchens such as casual dining restaurants typically require cleaning every six months.
  • Low-volume kitchens like seasonal cafes, churches, or senior centers may need professional cleaning only once a year.

Factors That Affect Cleaning Frequency

While NFPA standards provide a good starting point, several factors can influence how often your exhaust system needs cleaning:

  • Type of cuisine: Greasy foods like fried chicken or burgers produce more residue than baked or grilled dishes.
  • Cooking equipment: Fryers, grills, and broilers generate more airborne grease compared to ovens or steamers.
  • Operational hours: The more your kitchen operates, the faster buildup occurs.

Signs It’s Time for an Early Cleaning

Even with a regular schedule, certain warning signs indicate that your system may need cleaning sooner:

  • Persistent smoke or lingering odors in the kitchen
  • Visible grease around hood edges
  • Reduced suction from the exhaust fan
  • Increased fan noise or vibration

If you notice any of these signs, it is best to schedule an inspection right away.

Benefits of Routine Cleaning

Regular exhaust cleaning not only ensures compliance but also extends the life of your ventilation equipment, improves air quality, and reduces energy costs. It also gives peace of mind knowing that your kitchen is operating safely and efficiently.

Conclusion

The frequency of exhaust cleaning depends on your restaurant’s unique operations, but consistency is key. Partnering with a professional cleaning company like Grease Goblins ensures that your system is serviced at the right intervals and maintained to the highest standards.
