Set the fan speed on high except in very humid weather. When it's humid, set the fan speed on low. You'll get better cooling, and slower air movement through the cooling equipment allows it to remove more moisture from the air, resulting in greater comfort.
Save time searching for your tools by organizing your workshop. Use your wallspace for good visibility and easy access. Open shelving is great for storing heavy tools and organizing shop hardware. Drawers are a good place for smaller tools and especially sharp ones. Make sure your working surfaces are large and free of clutter.
