The AIRAH Technical Handbook has long been considered one of the most valuable benefits of an AIRAH membership. For more than 30 years, it has been an integral part of AIRAH’s service to its members and is regarded as the go-to resource for those working in the HVAC&R industry.  
 
The Handbook summarises the key components of AIRAH’s Design Application (DA) manuals. Its success can be attributed to the hundreds of AIRAH members who have assisted in its content development, review, and curation. 
 
First released in May 1989, the Handbook is now in its sixth edition. It has been released in 2021 following a review and modernisation of the technical resource in AIRAH’s Centenary year.
