Quickly what is to be said about that book is that it is mainly addressed to people with some experience in the field and not to newcomers. well structured deals in good detail with all aspects of organizing your HVAC systems operation and maintenace. Gives good guidelines for people that are not sure if they want to run the equipment themselfs or outsource the operation. It helped me a lot deciding to outsource the operation of our steam plant. I would generally recommend it as a good reference for the evereday problems that HVAC equipment runs into and for the organization of your maintenace of your equipment. It could though deal in greater depth with the aspects of HVAC equipment design and installation.
