Kitchen Exhaust Hood Repair Needs in Southlake Restaurants and Kitchens

Kitchen exhaust in Southlake Town Square often has to travel up through buildings with offices above the shops, ending at fans on the roof, so a fan problem can go unnoticed until the kitchen fills with smoke or heat. Town Square was built in phases, with the first blocks opening in 1999 and a second phase in 2006, so fans, belts and make-up air units in the earliest buildings may be original or on their second set of motors.

Charbroilers and fryers put the heaviest grease load on the system. Grease that builds up in filters, ducts and the fan housing restricts airflow and raises fire risk, so hood cleaning on the schedule your fire code and insurer require is essential, along with regular filter cleaning by staff. Warning signs are smoke spilling past the hood edges, a fan that squeals or vibrates, or doors that pull hard because make-up air has failed.

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

Very likely. When the make-up air unit stops, the exhaust fan keeps pulling air out of the kitchen with nothing replacing it, so the space goes under negative pressure. Doors pull hard, pilot lights can flicker and the hood captures smoke poorly. Check the make-up air unit’s breaker and filters, then call for service.

Yes. We work on rooftop upblast fans, inline fans and the make-up air equipment that pairs with them. In multi-story Town Square buildings, roof access may run through a hatch or a locked stair controlled by property management, so arrange access before the visit and tell us where the fan sits.

A brief squeal at startup usually means the belt is loose, glazed or worn. Running it that way can lead to a broken belt and a sudden loss of exhaust during service. Have the belt and pulleys checked soon. If the fan stops or slows noticeably, shut down the cooking under the hood until it is repaired.
