Vent hood repair in San Francisco
Poor airflow, a rattling fan, or grease buildup that won't clear even after cleaning usually means something further up the exhaust path needs attention. We repair vent hood systems across San Francisco with same-day service.
Signs your vent hood needs a repair
- Smoke and steam linger in the kitchen instead of clearing
- Airflow stays weak even right after cleaning the filter
- A rattling or grinding sound from the fan blades
- Grease residue building up on nearby cabinets
- The exhaust damper flap seems stuck partway open or closed
Common causes we find
When airflow stays weak after cleaning the filter, the issue is often further down the line, a grease-clogged duct or a stuck exhaust damper. Rattling usually means loose mounting hardware or a worn fan blade bearing, which can eventually seize the motor if left alone. In older San Francisco buildings, long or narrow duct runs are also more prone to buildup over time.

Vent hood repair questions, answered
What's the difference between a vent hood and a range hood?
The terms are often used interchangeably. A vent hood typically refers to the ducted exhaust system that carries air outside, while range hood can mean the whole unit including ductless models.
Why is airflow weak even after cleaning the filter?
If cleaning the filter doesn't help, the duct itself may be blocked with grease buildup, or the exhaust damper may be stuck partially closed.
How much does vent hood repair cost?
Vent hood repair typically costs between $100 and $300, similar to standard range hood repair, depending on whether the fan, ductwork, or controls need attention.
Why does my vent hood rattle when running?
Loose mounting hardware or a worn fan blade bearing usually causes rattling. It's worth fixing quickly since a failing bearing can eventually seize the motor.
Do you clean or inspect exterior ductwork?
We inspect and clear ductwork that's contributing to poor airflow as part of the diagnostic, especially in older San Francisco buildings with long duct runs.
