A key component to passing the Mechanical HVAC & Refrigeration PE Exam is to obtain and to study the necessary references. These references contain the equations, skills, terms and concepts that appear on the Mechanical HVAC & Refrigeration PE Exam.
Engineering Pro Guides teaches all the necessary skills and concepts required to pass the Mechanical HVAC & Refrigeration PE Exam.

Must Have References for the HVAC & Refrigeration PE Exam
1. Must Have References for
the HVAC & Refrigeration
PE Exam

2. Introduction
The following references are recommended to be reviewed prior to the
exam and should be used during the exam. When reviewing these
references, make sure you first understand the content. These references
do not go into depth on explaining the equations or concepts but are
simply references. If you require more background information on any of
the information in these references, then you may need to research that
information on the internet. Secondly, you should be very familiar with the
indices of these references and should be able to navigate the references
to find information quickly. This may require you to insert tabs into the
references. Once you have completed these two tasks then you should
be ready to use these references during the exam. (Tip: It is helpful to
have the indices of your references printed separately to allow you to
have both the index and the reference material open at the same time,
making for quicker searches.)
3. NCEES HVAC & Refrigeration PE Topics
