Range hood repair
in the Bay Area
A hood that no longer pulls smoke isn't just annoying — it leaves grease on your cabinets and moisture in the walls. Most weak hoods are a blocked duct, not a dead motor.
Symptoms
What we see most.
If any of this sounds like your unit, the diagnosis is usually straightforward and the repair is same-visit.
Runs but doesn't pull smoke
Blocked duct, a stuck backdraft damper, or grease-saturated filters that have never been washed.
Loud rattling or grinding
Worn motor bearings or a fan wheel loaded unevenly with grease.
Lights don't work
Usually the socket or switch rather than the bulb, especially on halogen hoods.
Turns on by itself
Moisture or grease in the touch control panel — common on flat-panel and island hoods.
Weak airflow even on high
On recirculating hoods, this is almost always a saturated charcoal filter rather than a motor problem.
Fan runs but seems weaker than it used to
Grease buildup narrowing the duct interior over years, or a backdraft damper that isn't opening fully.
Persistent grease smell in the kitchen
Charcoal filters have a service life and stop absorbing odor long before they look visibly dirty.
Vibration or wobble at higher fan speeds
A fan wheel that's picked up an uneven grease coating, throwing it out of balance.
What we service
Ducted & recirculating — different fixes entirely.
Ducted hoods
Exhaust to the outside through wall or roof ducting — most failures trace back to airflow restriction somewhere in that path.
- Duct cleaning and rebalancing
- Backdraft damper repair
- Fan motor and wheel replacement
- Ducting inspection through wall or roof
Recirculating hoods
Filter smoke and grease rather than exhausting it outside — service here is almost entirely about the filter, not the motor.
- Charcoal filter replacement
- Grease baffle filter service
- Motor and switch repair
- Conversion assessment to ducted, where possible
Common causes
Why it breaks down.
Grease-saturated filters choke airflow gradually
A filter that's never been washed restricts airflow long before the motor shows any sign of struggling — most weak-suction calls trace back here.
Ducting accumulates grease over years
The inside of duct runs narrows slowly as grease builds up, and it's invisible until airflow has dropped noticeably.
Backdraft dampers stick from grease and disuse
The flap that's supposed to open when the fan runs can gum up with grease residue and stop swinging freely.
Charcoal filters have a real service life
Recirculating hood filters lose their odor-absorbing capacity over months of use, regardless of how clean they look.
Motor bearings wear from constant grease exposure
Range hood motors run in a greasy environment by nature, which shortens bearing life compared to a cleaner-running motor.
Touch controls fail from heat and moisture exposure
Panels mounted directly above a cooking surface take on steam and grease vapor every time the stove is used.
Care tips
Keep it running longer.
- Wash metal grease filters monthlyDishwasher-safe on most hoods — this single habit prevents the majority of weak-airflow complaints.
- Replace charcoal filters on scheduleUsually every 3 to 6 months depending on cooking frequency — check your model's manual, since these can't be washed and reused.
- Wipe down the fan intake area regularlyGrease that never reaches the filter can still coat the intake and restrict airflow at the source.
- Run the hood on high for a few minutes after cookingThis clears residual smoke and grease vapor before it has a chance to settle into the ducting or filter.
- Have ducted systems inspected every few yearsA duct that looks fine from the hood opening can still be significantly restricted further along its run.
- Don't ignore a persistent grease smellOn a recirculating hood, that's the clearest sign the charcoal filter is spent, not a sign something's broken.
Pricing
Priced after diagnosis, not before.
Parts and labor for range hood repair vary too much by brand and fault to publish a flat rate honestly. A technician diagnoses the issue on site and gives you the exact price in writing — nothing starts until you approve it, and the diagnostic fee is applied to the repair.

Questions
Before you call.
Ducted or recirculating — which do I have?
If there's no duct through the wall or roof, it's recirculating and it filters rather than exhausts. Those need charcoal filters changed, not repaired.
How much airflow do I actually need?
Roughly 100 CFM per linear foot of range for a wall hood, more for a pro-style gas range. We measure rather than upsell.
Can you install a hood where there wasn't one?
Yes, including ducting through wall or roof. This usually needs a permit, and we handle that conversation up front.
How much does range hood repair cost?
Depends on the issue — a filter or switch repair is minor, a fan motor replacement or duct rebalance costs more. We quote in writing after diagnosis.
How fast can you fix a range hood that's not pulling smoke?
Same-day in most cases when you call before early afternoon.
Can a recirculating hood be converted to ducted?
Sometimes, if there's a viable path to the outside. We assess it honestly — not every kitchen layout makes it worth the cost.
