According to NFPA 96 guidelines, the cleaning frequency depends on your kitchen's volume of cooking. High-volume kitchens like fast food or 24-hour diners typically require monthly cleanings. Moderate-volume establishments may need quarterly service, while low-volume or seasonal kitchens can often go six months to a year between cleanings. Staying on schedule is critical to avoiding grease buildup, fire hazards, and failed inspections.

Hood cleaning is essential for fire prevention, proper ventilation, and regulatory compliance. In a busy restaurant kitchen, grease and smoke accumulate quickly in the exhaust system. If not cleaned regularly, this buildup can lead to dangerous grease fires, foul odors, poor air quality, and failed health or fire inspections. For Columbus restaurant owners, routine hood cleaning isn’t just smart — it’s required.

Deep cleaning a commercial range hood involves a step-by-step process to remove grease and contaminants from the entire system. First, filters are taken out and soaked or replaced. Then, degreasers and specialized equipment are used to scrub the hood, fan blades, ductwork, and all internal components. The process ensures your system operates efficiently and remains fire-safe.

Yes, range hood vents absolutely need cleaning. Over time, they collect layers of grease, dust, and smoke residue, which not only restrict airflow but also become a serious fire risk. Cleaning your vents regularly extends the life of your exhaust system, improves indoor air quality, and helps maintain compliance with local Columbus health and fire codes.

Some of the most common signs include visible grease around the hood, strong lingering cooking odors, reduced airflow, noisy exhaust fans, or smoke not venting properly.
