Technical Reference Guide

This guide will help you identify, date and understand critical features for 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 information they'll appreciate.

There is also helpful information on determining the 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 Carson Dunlop's own engineers to date mechanical equipment and you too will find that this newly updated version will soon become an indispensable part of your toolkit.

The Technical Reference Guide is now available for $79 and can be purchased from our online store or call us at 1-800-268-7070 to place your order.
