AIRAH DA19 HVAC&R Maintenance Application Manual – Fourth Edition

The AIRAH DA19 HVAC&R Maintenance Application Manual is the definitive industry reference for planning, specifying, procuring, delivering and assessing maintenance for heating, ventilation, air conditioning and refrigeration systems. Published by the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH), this fourth edition builds on decades of accumulated industry knowledge and provides a structured, practical framework for anyone responsible for HVAC&R system maintenance.

Whether you are a building owner, facility manager, maintenance contractor, system designer, commissioning engineer or service technician, this manual delivers the guidance needed to keep complex HVAC&R systems operating at peak efficiency. It covers the what, why, how and when of maintenance, from initial design considerations through to ongoing system tuning and long-term sustainability. This is not a theoretical textbook; it is a working application manual designed to be kept close at hand and used daily.

Detailed Maintenance Schedules for HVAC&R Plant

The extensive maintenance schedules in Appendix A are a cornerstone of this manual. Each schedule lists specific maintenance actions with recommended intervals in months and explanatory notes on why each action matters and what to look for. The schedules cover every major item of HVAC&R plant found in commercial, industrial and institutional buildings. Appendix B demonstrates how to compile these individual equipment schedules into a complete system maintenance program, with a step-by-step worked example showing how to integrate cross-referenced schedules into monthly, quarterly, six-monthly and annual maintenance plans.

The cross-reference matrix in Schedule A40 is particularly valuable for maintenance planners, showing at a glance which additional equipment schedules need to be consulted when developing a maintenance program for any given plant item. For example, an air handling plant maintenance program must incorporate schedules for automatic controls, coils, dampers, drives, electrical components, motors, fans, filters and vibration isolation.

Sustainability and Energy Efficiency

This fourth edition places strong emphasis on the role of maintenance in reducing the environmental footprint of buildings and processes. It addresses energy efficiency maintenance, water conservation for cooling towers and evaporative systems, refrigerant management including leak detection and pump-down systems, indoor air quality maintenance and strategies for dealing with oversized or undersized plant. The manual links maintenance directly to building performance rating schemes such as Green Star, NABERS and ABGR, showing how effective maintenance is essential for achieving and retaining sustainability ratings.

Compliance and Regulatory Context

The manual provides detailed guidance on the legal and regulatory framework surrounding HVAC&R maintenance, including the Building Code of Australia (BCA) requirements for safety measures and energy efficiency, AS 1851 fire and smoke control maintenance, AS/NZS 3666.2 microbial control for air handling and water systems, and the Australia and New Zealand Refrigerant Handling Code of Practice. It explains the minimum maintenance requirements that must be satisfied and the records that must be kept to demonstrate compliance.

Who This Manual Is For

This application manual serves building owners and operators, facility managers, tenants and occupants, system designers, installation contractors, commissioning engineers, maintenance providers and technicians, auditors and surveyors, and building regulators. Table 1.1 in the manual provides a guide to which sections and appendices are most relevant to each stakeholder group.

The manual is equally applicable to large commercial and industrial buildings as it is to smaller light commercial and residential systems, and can also be applied to process-related HVAC&R systems rather than just building services. It is designed to be used in whole or in part by anyone with an interest in HVAC&R system maintenance.
