Year-round Energy Savings

Big Ass overhead 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, decreasing the work of your heater and leading to savings as high as 30 percent.

Unrivaled Warranties

  • Enjoy your fan, worry-free, with a lifetime hub and airfoil warranty.
  • 5-year non-prorated warranty for all components with our Factory Certified Installation. Years 6-12 are prorated. (Receive a 3-year full coverage warranty without our Factory Certified Installation. Years 4-12 are prorated.)
  • Big Ass Fans handles all warranties without redirecting you to component manufacturers. We make it, we sell it, we install it and we guarantee it.
  • See our warranties below for more information.


Plus Hybrid Airfoil

  • Pushes air at an angle, moving it over and around obstructions
  • Unique, aerodynamic airfoil and winglet designs enhance both energy efficiency and airflow by eliminating turbulent airflow at the airfoil tips


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

  • Winter Mode: Automatically adjusts speed to minimize 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

Factory-Certified Installation

  • A dedicated Big Ass Fans project manager to handle your project start to finish and forever after
  • Assurance that your fan will be installed 100% correctly, by factory-trained and certified installers who know Big Ass Fans inside and out

Featured Case Study: Paul Cates Stable

Summers down here can be tough. Before buying Big Ass Fans, there wasn't much we could do about the heat, but this summer has been a different story. The fans help a lot and are worth every penny. Paul Cates, Owner, Round Rock, Texas


Cates installed two 24-ft (7.3m) Powerfoil®8 fans by Big Ass Fans®, greatly relieving his patrons, horses and himself. The fans work with the arena’s exhaust system to generate a consistent, cooling breeze throughout the space, keeping lessons and training sessions comfortable. “The horses and I have to deal with the heat the most, and Big Ass Fans help me get through the day,” Cates said. He noted his particularly willful horses, which were once especially affected by soaring temperatures, now rarely experience fatigue.
