    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.

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.
