HVLS fans already save a ton of money over conventional heating and cooling solutions. But MacroAir 6ixBlade™ technology takes them even further by increasing fan performance with much less energy. At only 1hp, it costs less then 15¢ an hour to run a MacroAir 20′ fan. And since you won’t run your HVAC as frequently, the energy savings can really add up. One customer wrote he’d saved almost 70% on his monthly HVAC costs.
