What Legacy Hood Cleaning Service Does and How It Works

Legacy Hood Cleaning Service handles commercial kitchen exhaust hoods and ductwork

Legacy Hood Cleaning Service is a South Carolina-based company that specializes in cleaning and maintaining commercial kitchen ventilation systems. They clean the exhaust hoods, filters, and ductwork that collect grease and smoke in restaurants, cafeterias, catering kitchens, and other food service operations. The service removes built-up grease that can become a fire hazard and reduces airflow efficiency.

The company operates in the Midlands and surrounding regions of South Carolina. They work with restaurants of various sizes, from small independent establishments to larger chains, as well as institutional kitchens in schools and hospitals. Their work is part of routine maintenance that health departments and fire codes require for commercial kitchens.

Key Takeaways

• Legacy Hood Cleaning Service removes grease buildup from kitchen exhaust hoods, filters, and ducts that accumulate during normal cooking operations.
• Regular cleaning is required by South Carolina fire codes and health department regulations to prevent fire hazards and maintain proper ventilation.
• The service typically includes pressure washing of hood surfaces, filter cleaning or replacement, and ductwork inspection and cleaning.
• Most commercial kitchens need hood cleaning on a schedule that depends on cooking volume—high-volume operations may need monthly service, while lower-volume kitchens might need quarterly or semi-annual cleaning.

What gets cleaned during a hood cleaning visit

A hood cleaning service addresses several components of the ventilation system. The hood itself—the metal canopy that sits above the cooking line—collects grease on its interior surfaces and filters. The filters trap smaller particles and grease droplets; they may be cleaned and reused or replaced depending on their condition. The ductwork that runs from the hood to the roof or exterior wall accumulates grease inside the pipes, which reduces airflow and creates fire risk.

Legacy Hood Cleaning Service uses pressure washing equipment to remove grease from hood surfaces and ductwork. They inspect the system for damage, corrosion, or areas where grease has built up to dangerous levels. Some jobs include cleaning the makeup air unit—equipment that brings fresh air into the kitchen to replace air pulled out by the exhaust system—and the roof penetration where the duct exits the building.

Why commercial kitchens need regular hood cleaning

Grease buildup in kitchen exhaust systems is a documented fire hazard. When grease accumulates inside ducts and on hood surfaces, it becomes flammable material that can ignite if exposed to high heat. South Carolina's fire code requires commercial kitchens to maintain clean exhaust systems, and the frequency of cleaning depends on the volume of cooking. The National Fire Protection Association (NFPA) publishes standards that most jurisdictions follow, which specify cleaning intervals based on how much the kitchen cooks.

Beyond fire safety, a clean hood system maintains proper ventilation. When filters and ducts clog with grease, the exhaust system cannot pull smoke and heat away from the cooking line effectively. This makes the kitchen hotter and less comfortable for staff, and it can affect food quality. A functioning hood also removes cooking odors that would otherwise linger in the dining area.

Health inspectors check hood cleanliness during routine inspections of food service establishments. A kitchen that cannot show evidence of regular hood maintenance may receive violations or be required to close until the system is cleaned.

How often your kitchen needs hood cleaning

The cleaning schedule depends on cooking volume and the type of food prepared. High-volume operations—such as busy restaurants with fryers, grills, and char-broilers running most of the day—typically need hood cleaning every month or every six weeks. Medium-volume kitchens might need cleaning every quarter. Lower-volume operations like small cafes or catering kitchens that cook less frequently may need cleaning twice a year.

Kitchens that use a lot of deep fryers generate more grease than those that primarily grill or bake, so frying-heavy operations need more frequent cleaning. Some commercial kitchens track their hood cleaning schedule as part of their regular maintenance log, which they show to health inspectors and insurance companies.

What to expect during a hood cleaning appointment

When Legacy Hood Cleaning Service arrives, they typically begin by inspecting the hood system to assess grease buildup and identify any damage. They may ask about the kitchen's cooking volume and the last time the system was cleaned. The cleaning process involves using pressure washers and degreasers to remove grease from the hood interior, filters, and accessible ductwork. The job can take anywhere from one to several hours depending on the size of the system and how much buildup is present.

Most hood cleaning companies ask the kitchen to shut down cooking during the cleaning, since the work involves water, chemicals, and pressure washing. Some kitchens schedule cleaning during off-hours or on a day when the kitchen is closed. The company should provide documentation of the cleaning—often a certificate or report—that the kitchen can keep for health inspectors and insurance purposes.

Connecting hood cleaning to your pressure washing maintenance

Hood cleaning is a specialized type of pressure washing that requires knowledge of commercial ventilation systems and fire code requirements. While general pressure washing removes dirt and algae from exterior surfaces, hood cleaning removes flammable grease from interior kitchen systems. The equipment and techniques differ because the goal is not just cleanliness but fire safety and code compliance.

Some pressure washing companies offer both exterior cleaning and hood cleaning services, while others specialize only in one. Legacy Hood Cleaning Service focuses on the kitchen ventilation side of the business. If your restaurant or food service operation needs both exterior pressure washing and hood cleaning, you may work with one company for both services or coordinate between two specialists.

Frequently Asked Questions

How do I know if my hood needs cleaning?

If you see visible grease buildup on the hood interior or filters, or if the exhaust system is not pulling smoke away from the cooking line as it should, cleaning is overdue. Most commercial kitchens follow a set schedule rather than waiting for visible problems. Your health inspector or fire marshal can advise on the required frequency for your specific operation.

Can I clean the hood myself?

You can clean the hood exterior and filters yourself as part of daily kitchen maintenance, but professional ductwork cleaning requires specialized equipment and knowledge of fire codes. Most jurisdictions require that the ductwork and interior system be cleaned by a licensed or certified service to meet code requirements. Documentation from a professional service is what health inspectors and insurance companies expect to see.

What happens if I don't get the hood cleaned regularly?

You risk fire hazard, failed health inspections, and potential liability if a fire occurs in the exhaust system. Insurance companies may deny claims if they find that the hood was not maintained according to code. You may also face fines from your local fire marshal or health department.

How much does hood cleaning usually cost?

Pricing varies based on the size of the hood system, how much grease buildup is present, and how much ductwork needs cleaning. A single hood cleaning can range from a few hundred dollars to over a thousand for large systems with extensive ductwork. Most companies provide a quote after inspecting the system. Kitchens that schedule regular cleaning often pay less per visit than those that wait until heavy buildup requires more intensive work.

Do I need a contract with a hood cleaning company?

Many commercial kitchens sign maintenance contracts with hood cleaning services to ensure regular cleaning on a set schedule. A contract locks in pricing and guarantees that cleaning happens on time, which helps with code compliance. You can also call for one-time cleaning jobs, though regular customers often get better rates through a contract.
