Kitchen Exhaust Cleaning

Exhaust hood cleaning is extremely important.

It does not matter how large or small your commercial kitchen is or what volume of food is produced. In time, combustible grease and oil builds up in all hoods. Everyone in the building could be in danger if these combustibles ignite.

Hood cleaning and maintenance is critical for keeping your exhaust system functioning at top performance.

Grease Filter Exchange

Grease filters within your kitchen exhaust system exist to reduce the amount of vaporized grease that ends up within your exhaust system ducts, where it can cause a flash fire. Clean filters can trap up to 70-80 percent of the grease passing through them. If your filters are saturated with grease, they can’t do their job properly and you will end up with reduced efficiency of your system and a dangerous grease accumulation right above your cooking appliances.

Investing in regular grease filter replacement and cleaning will help reduce your risk of fire and avoid its potentially devastating impact on your business.

Dryer Ducts

Commercial kitchen exhaust ducts are coated with grease, oil, and other residues that may ignite and cause fire to spread rapidly throughout the entire system. One in every four accidental fires in commercial buildings are attributed to cooking and exhaust systems.

It is vital to keep kitchen ducts clean.

Our cleaning system reduces the risk of kitchen fires, improves ventilation and enhances the entire working environment.

Range Cleaning

Maintaining hygiene standards is essential in the food preparation industry. Our service helps you maintain a high standard of hygiene in your kitchen.

While commonly used cleaning equipment such as multi-purpose cleaners, bleach and regular wiping cleans certain surfaces, it is the bacteria in hidden crevices that can evade the kitchen and become a health hazard. Our system removes burnt on carbon and fat deposits ensuring any potentially harmful bacteria are eliminated.

Grease Traps

Regular grease trap cleaning helps prevent backups inside and outside your restaurant and stops grease from entering the municipal sewer line.

Whether you are in need of scheduled maintenance grease trap cleaning or an immediate grease pumping service… we are ready to help you.

We make certain that your device is fully pumped, removing all content from top to bottom.

Smoke Eaters

Statistics show it takes only 10 seconds for someone to realize there is something wrong with the smell of a bar/pub lounge area. This can lead to customer dissatisfaction. Spraying air freshener in a room works for only a few moments. You need another solution.

Smoke eaters are devices that remove smoke and odors from a room. It will remove tobacco smoke, as well as pollen, dust, vapors and many other irritants.

Removing tobacco smoke from the air requires a significant carbon filtration process. The process requires a heavy duty filter, and a very heavy duty fan to move air through it. We only use commercial grade equipment to ensure proper filtration and air flow.

Air Filter Exchange

Stop wasting money.

Replacing your air filters on a specified frequency will alleviate stress on your HVAC equipment. Better efficiency from your air handling units will lower operating costs.

Our filter costs are much lower than full-service HVAC companies, and as a result, our HVAC air filter replacement service is more cost effective.
