Is Your HVAC System Making You Sick ?

The air we breathe indoors-in our homes, our offices, and our schools-is the single most constant environmental factor in our lives. Yet, for too long, we have treated our building’s vital respiratory system, the HVAC (Heating, Ventilation, and Air Conditioning), as an afterthought-a mechanical utility whose only job is to maintain a set temperature. This book is a direct challenge to that mindset.

After more than three decades as a global HVAC and MEP consultant, I have seen firsthand the devastating link between a poorly managed building system and human health. I’ve walked through countless facilities-from industrial complexes to high-end residential towers-where the cooling coils were breeding mold, the ventilation was non-existent, and the very ducts designed to deliver comfort were circulating sickness. These failures are not inevitable; they are, in fact, entirely predictable and solvable.

Is Your HVAC System Making You Sick? is your definitive guide to recognizing these invisible hazards and taking control of your indoor environment. It moves beyond simple awareness to provide a practical, consultant-level diagnosis and remediation plan. I wrote this book to empower homeowners, building managers, architects, and engineers to ask the right questions, demand higher standards, and implement the proven, innovative solutions that ensure not just comfort, but lasting health and safety. The answer to the question in the title is often yes. This book tells you exactly why, and what you can do about it.
