As a restaurant or bar owner, commercial hood ventilation maintenance should be at the top of your priorities. Besides mitigating fire hazards and the functional value of your system, you would value the aesthetics. From time to time, you need to hire seasoned professionals for cleaning the exhaust ducts, hood filters, extractor fans, and other components of the system.

In commercial environments, you have heavy-duty kitchen equipment, that runs for prolonged hours. The ducts and hoods above this equipment are meant to eliminate airborne contaminants, like smoke, heat, grease particles, and odors. Without a professional checkup, you would experience fire hazards within the system.

The reputed commercial hood ventilation cleaners recommend certain tips to maintain and clean these systems.

Maintaining commercial hood ventilation: How to go about it?

Hood filters

  • Firstly, the filters need to be extracted from the hood. In case the system has baffle filters or the ones with two parts, you need to separate them as per the manufacturer’s directions. Hiring competent ventilation cleaners would ease up the task.
  • Use an anti-grease detergent solution to soak the filters overnight.
  • Next, use a washware to clean the filters to do away with the grease. A hand sprayer can also serve the purpose, in case you do not have a washware.
  • Visually inspect the accessories for possible defects. Experts recommend holding the filters against the light. You need to get them replaced, if light passes through them.
  • Place the filters back to the hood after drying them. Remember, baffle filters need to be replaced once they are damaged. Reach out to a professional ventilation cleaner in case you need a replacement.

Exhaust ducts

  • The air ducts for the exhaust need to be fully sealed. Inspect these components for their tightness, and make sure that the sealant at the joint is perfectly working. A quarterly inspection would be enough to determine whether or not they need to be replaced.
  • Inspect the external fan in the exhaust system to eliminate grease or clogging. This might prevent the ducts from expelling the contaminated air properly.
  • The fan setting must be set on the exhaust mode, not the circulation one.
  • Ensure that the drains of the duct are functioning properly in the right area. Check out all the parts of the exhaust ducts for possible grease build-up. This would mitigate the chances of a grease fire.

Rooftop containment system

  • On a regular basis, you need to clean the hood filters by removing the hood filters and clean them as instructed.
  • Cleanse the grease collection traps and grease drain. Carefully wipe the surfaces made of stainless steel, ensuring that the hard materials do not scratch or damage the appliance.
  • Dip a soft cloth in a detergent solution to wipe off the surface of the hood. Professional ventilation cleaners recommend diluting half a cup of laundry detergent with one gallon of water. Now clean the extractor hood, removing the grains from the surface.
  • Remove the detergent solution with the help of a warm, clean cloth. Get a dry cloth, using which you can wipe off the hood. In case you have a temperature sensor on the hood, be careful to clean the area.
  • You need to carry out a quarterly inspection for detecting possible air or gas leaks in the hood extractor.
  • Prevent grease from accumulating in the ducts by regularly cleaning them.
