Kitchen Exhaust Hood Repair Needs in Highland Park Restaurants and Kitchens

Kitchen exhaust systems at Highland Park Village have to work within buildings that date to the 1930s and carry National Historic Landmark status. Exhaust fans and make-up air units usually sit on the roof, and in older buildings the duct path from the hood to the fan can be long or indirect, with limited roof access. If the fan loses speed or its belt slips, a compact kitchen fills with smoke and heat quickly, and it can spread toward the dining room.

Grease is the main cause of exhaust problems. Filters that are not cleaned often enough let grease reach the ductwork and fan, which raises fire risk and wears bearings and belts. Make-up air units need clean filters and working burners or heaters so the kitchen does not run under negative pressure, which makes doors hard to open and pulls in hot air. Clean hood filters on schedule, and when you call, tell us whether the issue is weak draw, noise, a stopped fan or a make-up air problem.

Common problems

What’s Wrong With Your Commercial Kitchen Exhaust Hood?

The kitchen exhaust hood problems we see most often, and the parts a technician checks first for each one.

SymptomCommon causes a technician checksGuide
Hood not pulling smoke or weak draftBroken or slipping fan belt, failed exhaust fan motor, clogged grease filters, grease-loaded fan wheel, make-up air imbalance
Check whether the exhaust fan on the roof is spinning and the grease filters are clean.

Possible causes a technician checks: Broken or slipping fan belt, failed exhaust fan motor, clogged grease filters, grease-loaded fan wheel, make-up air imbalance

Schedule a diagnosis
Exhaust fan won’t runFailed motor, broken belt, tripped breaker, starter or contactor fault, switch or control fault, thermal overload
Check the hood switch and breaker. If the hood lights work but the fan doesn’t, the fault is in the fan circuit.

Possible causes a technician checks: Failed motor, broken belt, tripped breaker, starter or contactor fault, switch or control fault, thermal overload

Schedule a diagnosis
Squealing, rattling or vibration on the roofWorn or loose belt, misaligned pulleys, dry or failing bearings, grease buildup unbalancing the fan wheel
A squeal that starts at fan startup is usually the belt. Grinding usually means bearings.

Possible causes a technician checks: Worn or loose belt, misaligned pulleys, dry or failing bearings, grease buildup unbalancing the fan wheel

Schedule a diagnosis
Doors hard to open or smoke drifting into the dining roomMake-up air unit not running or undersized, negative building pressure, exhaust and supply out of balance
Notice whether doors whistle or pull shut. That points to negative pressure from missing make-up air.

Possible causes a technician checks: Make-up air unit not running or undersized, negative building pressure, exhaust and supply out of balance

Noise and vibration usually mean a worn belt, failing bearings or grease buildup on the fan wheel that throws it out of balance. Keep running it only if it still draws properly, and have it checked soon, because a failed fan can stop the cooking line. A technician can inspect the belt, bearings, pulleys and wheel.

That usually points to too little make-up air. When exhaust removes more air than the make-up air unit supplies, the kitchen goes negative, doors resist opening and heat builds. Check the make-up air unit’s filters and whether it is running. If it is, a technician can test its motor, belt, heater and controls.

Yes, with coordination. Tell us how the roof is accessed and whether property management requires notice, an escort for roof work. Photos of the fan and its data plate help us plan parts. We schedule around service when possible so the kitchen is not left without exhaust during a meal period.
