HVLS Fan Maintenance in Marlboro, NY

During spring and fall tune-ups, we inspect every component that experiences wear. Blade surfaces are cleaned to remove dust buildup that reduces airflow and strains the motor. The motor housing is checked for corrosion, cracks, or debris. Bearings are examined for scoring or play that indicates replacement is approaching. Electrical connections to the motor and control box are tested for loose terminals or corrosion that can cause arcing or failure.

HVLS fan bearings support thousands of rotations per minute and need fresh lubrication to prevent friction damage. We use the correct lubricant grade specified by your fan manufacturer and apply it to all bearing points. Blade imbalance is a major cause of excessive vibration and bearing wear. We measure blade weight distribution and adjust or replace blades as needed to bring the fan back into true balance. This reduces noise and extends motor and bearing life.

The motor in an HVLS fan draws significant current, and any loose connection or corroded terminal creates heat and increases failure risk. We measure motor current draw to verify the motor is operating within manufacturer specifications. High amp draw indicates bearing friction or motor winding problems. We clean and retighten all electrical connections, replace corroded terminals, and test the control system to ensure it responds properly to speed and direction changes.
