Scheduled Preventive Maintenance
Fan inspection and servicing at each NFPA 96 cleaning visit — belt tension, bearings, motor operation, hinge arms, and grease collection basins checked before failures occur.
Fan Wheel Cleaning
Grease-fouled fan wheels cause vibration, reduced CFM, and motor overload. Fan wheel cleaning restores balance and airflow — included in every NFPA 96 service visit.
Fan Replacement
Direct-drive and belt-drive replacement fans sourced from major manufacturers. Standard sizes typically installed within 1–3 business days with NFPA 96 reconnection documentation.
Diagnostics
Why exhaust fan failures happen.
Constant operation, grease contamination, weather exposure, and deferred maintenance create predictable failure modes — most can be addressed proactively or repaired on emergency response.
| Failure Mode | Symptoms | Service Required |
|---|---|---|
| Worn or broken drive belt | Squealing, reduced airflow, belt visible on rooftop | Belt replacement — same-day fix |
| Failed motor bearings | Grinding or rumbling noise, excessive vibration | Bearing replacement or motor swap |
| Grease-fouled fan wheel | Vibration, noise, reduced CFM, motor overload | Fan wheel cleaning (at NFPA 96 service) |
| Burned motor winding | Fan won't start, tripped breaker, burning smell | Motor replacement |
| Failed capacitor (single-phase motors) | Motor hums but won't start or start/stop cycles | Capacitor replacement |
| Hinge arm / access door failure | Fan lid won't latch, weather exposure to duct | Hardware replacement |
