This document is an HVAC troubleshooting guide to help facilities managers and maintenance personnel solve indoor environment and energy or water consumption problems. Facilities managers are often the first point of complaint for occupants who are unhappy about their working environment but they may lack the technical expertise required to investigate problems. This document is a step-by-step guide to identifying indoor environmental quality (IEQ) problems that may be caused by the operation of the HVAC system. It allows managers in charge of HVAC facilities, particularly those without a technical background, to initiate investigations, follow their progress and perhaps perform a few simple checks. It does however require some knowledge of the HVAC systems installed. The document also contains a series of troubleshooting procedures for use by the maintenance personnel actually performing the investigations.
