It just depends. When it was 100°+ for sure. But I also have a second story that’s contained from the rest of the barn, so I don’t have to worry about bugs or rodents TOO much. If I didn’t have that separate space, I’d probably invest in an AC. The lower floor is also a cement tablet that chills overnight. Sometimes, I’ll keep the doors closed until the slab warms up. It all just depends. At night, even if it’s hot, I lock up. We leave the windows open on the second story with fans at that point.
