The frequency of commercial hood cleaning is determined by factors such as the intensity of use and the type of kitchen equipment. According to the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, the majority of commercial hoods should be cleaned on a quarterly basis. However, there are exceptions based on specific requirements, such as wood-burning stoves needing monthly cleaning and facilities with lower grease buildup needing less frequent cleaning, possibly even once a year.

The typical duration for a commercial hood cleaning can vary based on factors such as the size of the kitchen, the intensity of use, and the extent of the cleaning required. However, a common estimate is that most regular cleanings at typical restaurants take between 3-4 hours for thorough cleaning by two to three technicians, with one of them being a crew lead with at least one year of hood cleaning experience 

.

It's important to note that the frequency of cleaning can also vary based on the type of kitchen and its usage. Light-duty kitchens may only need biannual cleaning, while heavy-use commercial kitchens may require more frequent professional cleaning every few months 

. Additionally, the NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations provides guidelines for the frequency of cleaning, and it's essential to consider these recommendations when determining the cleaning schedule for commercial hoods 

.

Ultimately, the duration of a typical commercial hood cleaning can depend on the specific requirements of the kitchen, the expertise of the cleaning team, and the extent of the cleaning needed to ensure compliance with safety and health standards.

Additionally, anyone who cleans and inspects commercial cooking operations (hood cleaning) must hold a certificate of competency from the State Fire Marshal.

Cleaning a commercial kitchen hood yourself may not be advisable due to several reasons:

Complexity and Specialized Equipment: Commercial kitchen hoods are intricate systems that require specialized equipment and expertise to clean thoroughly. The interior components of the hood, such as the filters and ductwork, can accumulate grease, gunk, and grime, which may be challenging to clean effectively without the appropriate tools and knowledge 

.

Regulatory Compliance: Professional cleaning of commercial kitchen hoods is often a regulatory requirement. The National Fire Protection Agency (NFPA) mandates that commercial kitchen exhaust hood cleaning must be completed by certified and professional contractors to ensure compliance with safety standards and reduce the risk of fire hazards 

.

Safety and Fire Risk: Grease buildup in the hood system poses a significant fire risk. Improper cleaning or neglecting to clean the hood system can lead to increased fire hazards, poor indoor air quality, and potential fines or closure due to non-compliance with safety regulations 

.

Health and Safety Concerns: Accumulated grease and contaminants in the hood system can compromise the safety and hygiene of the kitchen environment, potentially leading to unpleasant odors, improper ventilation, and safety hazards for employees and patrons.
