If you’ve ever wondered how many years your kitchen extractor fan will keep pulling steam and smells away, you’re not alone. Most homeowners assume a fan lasts forever, but the truth is it has a practical life span that depends on use, cleaning, and quality. Knowing the typical life expectancy helps you plan maintenance and avoid nasty surprises when the fan quits during dinner prep.
On average, a well‑maintained kitchen extractor fan lasts between 7 and 12 years. Metal models with sealed bearings tend to hit the higher end, while cheaper plastic units often wear out around the seven‑year mark. Heavy cooking, grease buildup, and running the fan for long periods can shave years off the clock. If you notice a drop in suction or louder noise after a few years, it’s a sign the motor or fan blades are struggling.
The biggest enemy of an extractor fan is grease. Every time you fry or roast, tiny oil particles settle on the blades and motor housing. Wipe the surface with a damp cloth weekly, and a deeper clean every three months will keep the motor cool and efficient. Replace the filter according to the manufacturer’s schedule – usually every 1‑3 months – because a clogged filter forces the motor to work harder, shortening its life.
Another easy tip is to run the fan for only as long as needed. Once the cooking finishes, switch it off after a minute or two to clear remaining steam. Over‑running the fan for long periods after cooking wastes energy and adds unnecessary wear.
If you’re comfortable with basic DIY, you can check the fan’s motor for signs of overheating. Turn off the power, remove the cover, and feel the motor housing. Warm or hot to the touch, even after the fan has cooled, means the motor may be failing and needs replacement soon.
Regular visual inspections also help. Look for rattling blades, cracked housing, or frayed wiring. Small issues caught early are cheap to fix, while ignored problems can force a full fan replacement.
When the fan starts pulling less air, makes grinding noises, or the lights flicker, it’s time to consider a new unit. Modern fans are more energy‑efficient and quieter, so replacing an old fan can actually lower your electricity bills.
If you decide to replace, note the size of your current fan and the duct diameter. Most kitchen fans use a 100 mm or 150 mm duct; matching these measurements ensures a smooth installation. While some DIY‑savvy homeowners can handle the swap, hiring a qualified electrician guarantees safety, especially if new wiring is needed.
In short, expect your kitchen extractor fan to serve you for about a decade if you keep it clean and don’t overwork it. Watch for reduced suction, louder sounds, or overheating – these are early warning signs. With regular maintenance, you can squeeze the most out of your fan and know exactly when it’s time for a fresh, more efficient model.
