Kitchen Exhaust Hood Repair Needs in Prosper Restaurants and Kitchens

When a kitchen exhaust system weakens, the first signs often appear away from the hood: front doors that are hard to open, pilot lights blowing out, smoke rolling past the hood edge, or a dining room that smells like the fryer. These usually point to an imbalance between the exhaust fan and the make-up air unit. In Prosper’s summer heat it can be tempting to turn down make-up air to keep the kitchen cooler, but that pulls air through the dining room and doors instead.

Rooftop upblast fans on buildings at the Gates of Prosper and along US 380 sit in full Texas sun and wind, and their belts, bearings and motors wear accordingly. A squealing belt, a wobbling fan or grease pooling on the roof are all reasons to call. A hinge kit that lets the fan tip open for cleaning is worth having if yours lacks one. Clean hood filters on a set schedule; the fire suppression system is inspected separately by a fire protection company. Motor and electrical work belongs with a technician.

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

Yes. Restaurants at the Gates of Prosper and along US 380 commonly use rooftop upblast exhaust fans paired with make-up air units. We work on belts, pulleys, bearings, motors and controls. Tell us how the roof is reached, whether by ladder or hatch, and whether the fan is making noise, running slowly or not running at all.

That is a classic sign of negative pressure. The exhaust fan is pulling out more air than the make-up air unit brings in, so the building draws air through the doors instead. Check that the make-up air unit is on and that its filters are clean. If it is running and the problem continues, the fan speed, belts or air balance need a technician to look at them.

Yes. Along with restaurants, we serve kitchen exhaust for hotel kitchens, club and banquet kitchens, and other food service operations around Prosper. Kitchens that run long event days wear through belts and filters on a different schedule than a typical restaurant, so let us know your hours and event calendar so service can be planned around them.
