How long do range hoods last?
Most range hoods last 10 to 15 years. Vent hoods are commonly given 10 to 15 years; the motor, switch and lights fail before the housing does.
A range hood only helps if it is clean and actually vents grease and moisture out of the house. The filter is the part most people forget.

Range hood maintenance checklist by season
Spring
Soak or wash the metal grease filters in hot soapy water or run them through the dishwasher if the manual allows it. Wipe the underside and the fan blades if you can reach them.
Summer
Check that the outdoor vent flap opens when the fan runs and is not blocked by a nest or debris. A recirculating hood needs its charcoal filter changed on the schedule the maker gives.
Fall
Before more indoor cooking, replace burned-out bulbs and test each fan speed. Listen for a wobble that suggests a dirty or damaged blade.
Winter
If the damper sticks open, cold air blows in and the hood loses heat. Clean or replace a stuck damper. Check for frost around the outdoor cap.
Signs your range hood needs replacing
- The fan is loud, wobbles or has weak suction even after cleaning the filters.
- Grease drips from the hood or the filters stay greasy.
- The damper does not close or does not open.
- Lights or switches fail and parts are no longer available.
Typical range hood warranty
A limited one-year warranty on parts is common, sometimes with a longer motor warranty on premium models. Check the terms for your model.
An appliance warranty tracker keeps your range hood's coverage dates and receipt in one place.
What to keep for a range hood
- The receipt and installer invoice
- Model and serial number, often inside the hood near the filter or on the blower housing
- The filter size and part number
- The duct run notes, if an installer left them
Common questions
How long do range hoods last?
Most range hoods last 10 to 15 years. Vent hoods are commonly given 10 to 15 years; the motor, switch and lights fail before the housing does.
How often should I clean the range hood filter?
Many makers suggest about once a month if you cook often, and at least a few times a year otherwise. Your manual gives the interval.
Does a range hood need to vent outside?
Venting outdoors removes moisture, grease and combustion products. A recirculating hood filters some grease and odor but returns moisture to the room.
How do I maintain a range hood?
Follow your manual first. Each season: spring, soak or wash the metal grease filters in hot soapy water or run them through the dishwasher if the manual allows it. Wipe the underside and the fan blades if you can reach them. Fall, before more indoor cooking, replace burned-out bulbs and test each fan speed. Listen for a wobble that suggests a dirty or damaged blade.
