Technical Reference Guide
This guide will help you identify, date and determine the size of heating and cooling systems
going back more than 40 years. With entries for more than 200 manufacturers, you will be able
to provide your clients with the precise age and size of heating and air conditioning equipment.
There is also helpful information on determining the approximate adequacy of the units
you are inspecting as well as complete contact information on who to contact for more details
on the equipment.
This is the same guide created and used by CDW Engineering’s own engineers to date and size
mechanical equipment. You too will find that this newly updated version will soon become an indispensable part of your toolkit.
