Fire marshals conduct random inspections, and one of the first things they check is your kitchen exhaust system. Grease is a clear violation. But beyond avoiding fines, an uncleaned hood is a fire waiting to happen. Here are five warning signs that you need professional cleaning now.
1. Visible Grease Dripping from the Canopy or Filters
If you see streaks or drops of grease, your system is already overloaded. NFPA 96 requires cleaning before grease becomes “readily visible.”
2. Smoke Lingering Longer Than Usual
A clogged exhaust fan or duct cannot pull smoke out efficiently. If your kitchen stays hazy after cooking, airflow is compromised.
3. Unpleasant, Rancid Odors
Old grease gives off a distinct, foul smell. That odor means the grease has broken down and is releasing volatile compounds – and it’s highly flammable.
4. Grease‑Stained Ceiling Tiles or Walls Near Your Hood
Grease-laden air escaping from gaps in your ductwork leaves marks. This indicates poor sealing and heavy buildup inside.
5. Your Fire Suppression System Has Activated (Even Once)
If your Ansul or similar system went off, even as a false alarm, it’s a sign that grease may have interfered. Don’t wait for a real fire.
