Written in easy-to-understand, non-technical terms, this book can be both a ready reference and a training guide. Covering each type of indoor air hazard, the author explains the basics of proper ventilation and the relationship of the HVAC system to indoor air quality. He examines fundamental procedures for maintaining good air quality, including filtration, control of humidity and moisture, and duct cleaning. A full chapter is devoted to recent developments and procedures for controlling toxic mold. Case studies, an HVAC glossary, and several helpful directories are also included.
