What is a restaurant kitchen hood?
A kitchen hood is a ventilation contraption that hangs above the kitchen grills, burners, fryers, and other cooking appliances. The primary role of a kitchen hood is to soak in heat and grease from your burners and cookers to ensure the food prep area is hygienic. Installing a hood in your kitchen also improves fire safety because many kitchen fires are attributable to grease build-up.
Kitchen hoods are necessary equipment when starting a commercial kitchen business. Installing a kitchen hood in your commercial restaurant will significantly improve day-to-day management efficiency.
Kitchen hoods come in various sizes and finishes. Chief fire prevention classifies kitchen hoods into five major categories; ducted and ductless hoods, undercabinet hoods, wall mount hoods, ceiling mount hoods, and downdraft hoods.

NYC Kitchen Hood Cleaning Services
Chief fire prevention has over 36 years of hands-on experience and knowledge in cleaning hoods in restaurants and conducting routine maintenance for high-tech kitchen appliances. Our cleaning staff is trained on the National Fire Protection Association (NFPA) codes. The NFPA 96 outlines the "preventative and operative fire safety requirements required to minimize the potential threat of fire hazards in both private and public commercial cooking operations."
Chief fire prevention has operations across the country, serving many different states. Our New York branch offers the following restaurants hood cleaning services to New York City (NYC) clients:
Hood Fans Cleaning
Commercial kitchen hoods have a complex system of motors and fans. These components work together to draw in hot grease saturated air and distribute it evenly to prevent fire hazards. If your commercial kitchen hood's fan struggles to redistribute the air, then it's time to give them a thorough clean.
Before cleaning, the specialist will remove the protective fan covers and then unscrew the bolts in the central hub to release the fan. The cleaners will give your fans a thorough wash to remove the clogged debris using a soft-bristled brush. Soaking the fans in a sink filled with warm water and degreasing the solution is advisable if they are extra dirty.
After scrubbing, your hood fans will need rinsing using clean water before setting them aside to dry. Lastly, the cleaning expert will refit the protective covers to prevent users from accidentally touching the fan blades when the motor powers back on.
Hood Filters Cleaning
All kitchen hoods come with a baffle filter, a mesh-like attachment that easily slides in and out of the hood. They play an essential role in preventing fire hazards by spreading the flow of grease-saturated air particles. The restaurant hood cleaners will remove the filters and separate the stainless-steel spacers close to the grease traps.
The cleaners use a soft-bristled brush to scour through your filters to remove grease stains and debris. If the hood filters are compact, you can clean them in dishwashing equipment. However, commercial hood filters come in large sizes meaning they can be challenging to clean using regular dishwashers.
Our cleaning staff will soak the filters and steel spacers in your kitchen sink. More scrubbing will follow using a degreasing agent and warm water until the filters are grime-free. The filters will soak in warm water for a few hours before rinsing, drying, and reinstalling the filters, grease traps, and spacers.
Hood Ducts Cleaning
Over time, the ductwork in a commercial kitchen hood can get clogged from grease residues. Our cleaning specialists will disassemble the ducts and plugs from the primary system to clean them. The cleaning solution and materials are similar to that of hood filters. The technicians will place the ducts in a bucket with the cleaning solution and scrub the interior and exterior components using a non-abrasive brush pad.
After scrubbing, they will rinse the equipment and air dry it for a few hours. Once completely dry, they will reinstall the ductwork and its components.
How often should kitchen hoods be cleaned?
The NFPA 96 sets out restaurant owners' standards to ensure kitchen hoods and exhausts are well maintained. NFPA's recommended commercial hood cleaning schedule is as outlined below:
Monthly kitchen hood cleaning
The standard requires all kitchens that use solid fuel systems to clean their hoods and vents at least once every month. Solid fuel refers to all solid inputs such as firewood, charcoal, and coal that require combustion when cooking.
Quarterly hood cleaning
Restaurants with high volumes of operations should clean their hoods quarterly. Fast food joints and diners that open around the clock and do not use solid fuels also fall into this category.
Semi-Annually
Kitchen or cooking operations with a moderate volume of operations should clean their hoods at least once in six months.
Annually
NFPA 96 requires all restaurants or kitchen operation systems with low volume cooking to carry out professional kitchen hood cleaning at least once a year. This category includes churches, seasonal businesses, day camps, and restaurants serving only special events.
Quarterly hood cleaning
Restaurants with high volumes of operations should clean their hoods quarterly. Fast food joints and diners that open around the clock and do not use solid fuels also fall into this category.
