The Complete Handbook of Dehumidifiers

I manage six commercial properties and was tired of guessing whether I had the right dehumidifiers installed. Chapter 1 alone—the explanation of how refrigerant vs. desiccant units actually work—paid for the book. Now I understand why my basement unit fails in winter and what I should have sized for. Essential for anyone running buildings.

This is a genuinely useful reference for HVAC techs and contractors. The concrete examples (data center humidity specs, crawl space sizing, mold prevention thresholds) are exactly what I needed. My only gripe is the chapters on business opportunities feel a bit light for someone actually trying to start a dehumidifier service—would have liked more on pricing and customer acquisition. Still, highly recommend.

The technical content is solid and the writing is clear, which I appreciate. For professionals, this covers the basics well. That said, I was hoping for more advanced troubleshooting—my refrigerant unit is losing capacity and the book doesn't dig deep enough into diagnosis. It's a good intro and reference, but experienced techs might need supplementary resources.

Exactly what I needed. I own a water restoration company and constantly deal with humidity in damaged buildings. This handbook explains the science without being tedious, gives me the specs to choose equipment correctly, and shows me how to actually make money servicing dehumidifiers instead of just buying them. Clear, practical, no fluff.

The chapter on understanding how dehumidifiers work is excellent—finally a non-marketing explanation of absolute humidity, saturation, and why your unit stops working in a cold basement. The handbook is useful for reference, though I wish there were more case studies showing real-world problems and solutions. Good foundation, but could be deeper.
