Big Ass Fans Services

All Systems designs and installs Big Ass Fans HVLS systems for commercial warehouses, manufacturing facilities, agricultural buildings, retail spaces, and large residential applications. As an authorized Big Ass Fans dealer, we have technical expertise and access to complete product lines from 8 to 24-foot models. Installation begins with detailed site assessment including ceiling height measurement, space configuration review, structural evaluation of existing framing, and analysis of heating and cooling objectives. We perform engineering calculations to determine thrust loads and required structural reinforcement, then either reinforce existing joists and trusses or install new support structures capable of handling fan weight and operational loads. / Electrical installation includes running dedicated circuits from the main panel with breaker sizing appropriate for motor startup current—larger motors require substantial startup draws. We install variable-speed controls allowing operators to adjust fan speed and direction by season. For commercial applications, we integrate Big Ass Fans with building management systems enabling networked control across multiple units, occupancy-based automatic operation, and energy monitoring to track performance. Single-phase 120 to 240 volt service powers residential installations, while three-phase service is standard in commercial facilities. / For commissioning, we mount the fan on properly reinforced structural supports using heavy-duty brackets, connect all electrical wiring to controls and main panel, fill motor with appropriate bearing oil if applicable, perform blade balancing verification to ensure imbalance stays under one-quarter inch, test operation across all speed settings, and verify downward air movement in target zones. We educate facility managers and homeowners on seasonal operation strategies—faster speeds in cooling season, slower speeds in heating season—to optimize both comfort and energy consumption. Maintenance includes annual inspection of mounting brackets and structural supports for corrosion or looseness, motor bearing inspection and oil level verification, blade cleaning to remove dust accumulation that creates imbalance, and electrical connection inspection. We troubleshoot operational issues including excessive vibration or noise typically caused by blade imbalance from dust accumulation or loose hardware, motor speed control problems, and bearing wear. Big Ass Fans are built for decades of reliable service—many commercial installations operate 20 to 25 years with basic maintenance.
