Year-round Energy Savings

Overhead Big Ass Fans work with your HVAC to provide significant energy savings.

  • In summer, the fans’ cooling effect means the A/C can be set several degrees higher.
  • In winter, fans push the heat down from the ceiling, so your heater runs less, leading to savings as high as 30 percent.

  • Unparalleled 15-year non-prorated warranty comes standard for all components with our Factory-Certified Installation.

SmartSense is an automated system with three user modes: Winter, Summer and Manual.

  • Winter Mode: Automatically adjusts speed to minimise temperature differential between the floor and ceiling
  • Summer Mode: Increases fan speed as the floor-level temperature rises
  • Manual Mode: Takes the system off autopilot and gives the user full control of fan operation
  • SmartSense control system automatically adjusts for 24/7 comfort.

Occupancy Sensor

Powerfoil X3.0’s available occupancy sensor uses passive infrared technology to detect motion and automatically turn your fan on or off. The sensor returns the fan to its previous speed setting when you enter the space and shuts the fan off after a user-specified period of inactivity.

  • Convenient, hands-free operation
  • Automatic energy savings
  • Compatible with standard and premium controller options

Featured Case Study: American Airlines

Airlines need reliable products that will last for decades. Other manufacturers make pretty products or throw collections of parts together. Nobody thinks about an integrated system—except Big Ass Fans. Bruce Aycock, Senior Manager of Facilities Engineering, Charlotte, North Carolina


American Airlines installed four 24-ft (7.3-m) Powerfoil®X2.0 fans by Big Ass Fans® in the Charlotte line maintenance hangar to mix the air and create a uniform temperature, allowing facility managers to lower the thermostat set point by 5 °F (2.8 °C) without impacting worker comfort. In fact, the mechanics, who had previously worn bulky coats to make up for the lack of floor-level heat, took off their coats as soon as the fans began running. Bruce Aycock, lead engineer, was so impressed with the quality and durability of the Big Ass® product that he spearheaded a Big Ass Light™ installation in the company’s Dallas/Fort Worth hub.
