Any fan worth its blades can cool you off. But when you add a MacroAir fan to your heater configuration, you're maximizing your comfort and your savings. MacroAir was the first HVLS fan to run in reverse. Running in reverse redistributes warm air that has risen to the ceiling back down to the floor, which amplifies the effect of your EnergyLogic heater. So you save even more money and stay warmer longer. We're huge fans of those results.
