So in the business I run we sell HVLS (high volume low speed ) fans. Our is a specific line, made by the same people that make our loading docks. We put them in airplane hangars, warehouses, and field houses. However, the most well known brand is Big *** Fans. They can be purchased online through home depot, but will cost you anywhere from 800 to several thousand. But there are options for the homeowner. Hunter makes an industrial fan that is VERY affordable. Napa sells HVLS fans as well, but you're back up into the thousands. Hunters will be sub thousands.
$1.50/day is generally the operating cost for one of the 24' fans. Installation is generally involves perf angle and cables. CAT5 wires control the control boxes.
So there are indeed options. They really do work. And are worth it. I've seen the difference in peoples bills for sure.
