Beyond the Filter

Why Your Kitchen Isn't Safe Without Professional Duct-to-Fan Cleaning

Plenum behind the hood filters

As a restaurant owner or manager, you know that kitchen safety is a daily priority. You and your staff are diligent about cleaning the kitchen hood filters, often on a weekly basis. This is a critical task and your first line of defense against grease buildup. But what about the grease you can't see?

Even the cleanest, most regularly maintained filters cannot capture 100% of the grease-laden vapors your cookline produces. Over time, a fine mist of grease bypasses the filters and begins to accumulate in the areas you can't reach: the hood plenum, the ductwork, and the exhaust fan on the roof.

This hidden buildup is where the real danger lies.

The Hidden Fuel Source: From Buildup to Fire Hazard

That sticky layer of grease inside your ductwork is a highly flammable fuel source. All it takes is a single spark or a flare-up from the cooktop to ignite this grease, triggering a devastating fire that can travel from the hood, through the ducts, and onto the roof in minutes.

While your weekly filter cleaning is essential for reducing the amount of grease that enters the system, it cannot eliminate this risk. Only a professional, certified cleaning of the entire system can.

Insurance Compliance: What Your Policy Really Requires

Your insurance provider understands this risk. When they require "regular professional hood cleaning," they aren't referring to the filters. They are requiring a certified, "plenum-to-fan" cleaning to ensure the entire exhaust system is free of flammable residue.

Should a fire occur, and an investigation finds that the ductwork and fan were not professionally maintained to standard, your insurance claim could be denied—a catastrophic financial blow, even if you were cleaning your filters perfectly.
