We run an automotive restoration
We run an automotive restoration business in Texas and in the summer we see temps well over 100 degrees in the shop. AC was not really an option for our space and I'd like to think we're used to it, but I could see productivity take a dive when we reached midday. Adding the fan dropped temps significantly and gave us the comfort to keep cranking past midday, when before things would slow down to a crawl. That drop in temp is worth every penny when you see what can get done when your team doesn't feel like it's about to pass out!
