Centrifugal Roof Supply Fan Repair
Mechanical and electrical service for centrifugal roof supply fans with airflow, motor, belt, bearing, vibration, or control problems.
Commercial Ventilation
Built around the actual equipment.
A roof supply fan affects building pressure, ventilation balance, comfort, and kitchen operation. We inspect accessible fan components and controls, observe how the unit operates, and relate the findings to the connected duct and make-up-air system.
When to request service
Problems worth investigating early
Fan will not start or runs in the wrong operating schedule
Airflow is weak, uneven, or noticeably different than before
Belt slips, bearings sound rough, or the unit vibrates
Motor, contactor, disconnect, VFD, or interlock shows a fault
Diagnostic scope
What we evaluate
- Wheel, shaft, bearing, belt, pulley, motor, and cabinet observations
- Accessible voltage, contactor, disconnect, VFD, and control checks
- Rotation, vibration, airflow path, filters, dampers, and duct-condition review
- Repair and alignment plan with roof-access requirements noted
