Exhaust Fan & Vent Hood Repair in Dayton, TX
Green Mechanical is an HVAC contractor that also services commercial exhaust fans and vent hoods.
A kitchen exhaust system is what keeps a commercial kitchen safe and workable. When the hood can't clear the heat, smoke, and grease-laden air, the kitchen fills with it — the line gets hotter, the air gets heavier, and the whole cooking environment breaks down. A weak hood isn't just a comfort problem; it's a ventilation problem that the whole kitchen feels.
An exhaust system is a fan on the roof pulling air through the hood over the cooking line, with a make-up air side replacing what's pulled out so the building doesn't go negative. The fan relies on a motor, belts, and bearings to keep turning, and the hood relies on filters, a clear duct, and the right draw to actually capture what the line is putting off. When the fan slows, a belt slips, a bearing seizes, or the make-up air can't keep up, the draw drops and the kitchen stops clearing.
NFPA 96 is the standard for commercial kitchen ventilation, and the exhaust system has to keep its draw to do its job. This page covers repair of the exhaust fan and vent hood — the motors, belts, bearings, lights, and air balance that keep the system pulling. It does not cover hood cleaning or fire suppression work.
Common Problems We Fix
- Exhaust fan motors
A motor that's failed, overheating, or struggling to keep the fan turning.
- Belts and bearings
A slipped or worn belt, or a bearing that's noisy or seizing, slows the fan.
- Fans that won't start
The exhaust fan won't come on, leaving the hood with no draw over the line.
- Weak draw
The hood can't hold the capture it should, so smoke and heat spill into the kitchen.
- Hood lights
Burned-out or failed hood lights over the cooking surface.
- Make-up air problems
When make-up air can't keep up, the building goes negative and the exhaust can't pull right.
