Why Isn’t My Range Hood Pulling Smoke?

If your hood used to clear the air and now doesn’t, the cause is usually simple — and often fixable. Here’s what to check.

The most common cause: greasy filters

Clogged baffle or mesh filters are the number-one reason a hood stops pulling. As grease hardens, it chokes airflow. Cleaning or degreasing the filters often restores performance on its own.

Buildup in the hood and exhaust

Grease also collects on the hood interior, in the blower housing, and along the accessible exhaust. This hidden buildup quietly strangles airflow over months and years — and it’s exactly what a professional cleaning addresses.

Other things to check

If the system is clean and airflow is still weak, consider:

  • A blocked or damaged exterior vent cap
  • A disconnected or crushed duct
  • A failing blower motor
  • A hood that’s simply undersized (low CFM) for your cooking

Quick answers

Common questions

Will cleaning fix weak airflow?

Very often, yes — grease buildup is the most common cause. If it persists after a thorough cleaning, the issue may be mechanical or duct-related.

How do I know if it’s the filters or the exhaust?

We can tell you during a visit — and clean both so airflow is fully restored.
