Why Your Rangehood Sounds Loud — and What’s Really Causing It
The Low profile vent in the image is our new DV350LP Hi flow rangehood vent and the other is a common generic outdated restrictive vent.
If your rangehood sounds loud but doesn’t seem to pull much air, the motor usually isn’t the problem — it’s the venting system.
Most Australian homes are fitted with cheap, restrictive vents that block airflow. When air can’t escape easily, your fan has to work harder, creating that loud humming or roaring noise while still leaving cooking smells hanging around.
Common Causes of Poor Rangehood Performance
- Restrictive outdated vents that choke airflow
- Retro fitted ember mesh that reduce suction
- Cheap generic rubber boot and fittings that leak or vibrate
- Grease-trapping vent designs that stain ceilings and reduce performance
