Training Course
Syllabus:
Providing comfort to the people in your building is what this seminar is all about. And whether you are blowing heated or cooled air, keeping the temperature consistently comfortable for them is dependent upon you properly managing your HVAC electrical controls and air distribution systems. So we’ve designed this course to help you do just that. During this seminar students will learn how to “control” their controls, and how to use fundamental air distribution principles for achieving consistent HVAC comfort and efficiency in buildings, plants and facilities.
Course Objectives: Upon completion of this course,
students will receive a training certificate and .8 Continuing Education Units
for each day attended (1.6 credits for 2 days), indicating that the student has
learned to:
- Identify a problem as being Electrical, Mechanical or an Air Distribution issue
- Understand the basics of electricity as it applies to HVAC systems
- Read HVAC ladder diagrams and wiring diagrams
- Troubleshoot line voltage and low voltage problems
- Properly test operating controls and safety controls
- Troubleshoot air conditioning & heat pump systems
- Specify the correct air handling equipment required for the job
- Properly size HVAC air ducts
- Determine how many CFM are needed for your system
- Determine the air mixture condition at the cooling coil
- Understand the benefits and disadvantages of “short cycling”
- Control noise problems
- Avoid air conditioning drafts
- Test air handling equipment
And to be 100% certain you get the training you need, students are encouraged to
bring control and wiring diagrams or case studies from their own facility! If
you have a unique problem or situation, just let our instructor know. If he
can’t help you with your specific problem, we’ll refund your money – guaranteed!
Who should take this course This course is designed for
anyone working on HVAC controls and air distribution systems, or who are
responsible for keeping comfortable working or living conditions in their
buildings. Attendees come from a wide variety of industries, skill-levels,
company sizes and educational backgrounds. This course is also great for
cross-training technicians who work in multi-craft environments! So if you’re
not sure if you will fit in or will benefit from these classes, don’t worry –
you will – as long as your work involves HVAC!

Course Outline / Agenda DAY 1
HVAC CONTROL BASICS,
TROUBLESHOOTING & TESTING OVERVIEW HVAC system problems
can be divided into three major categories - Air Distribution, Electrical or
Mechanical. The part that causes most service headaches is the electrical
portion, and most of that can be traced back to control problems. So day 1 of
this seminar concentrates on overcoming the most common service problems
encountered in HVAC systems by teaching students to understand, troubleshoot and
test HVAC Electrical Controls.
During this seminar, students will learn the basics of electricity including
Ohm’s law and how simple series and parallel circuits are used in HVAC systems.
They will learn how to troubleshoot both line voltage and low voltage in their
systems. They will learn how to identify an electrical problem and determine a
solution for it by testing both operating controls and safety controls. Specific
situations unique to air conditioning and heat pumps will be discussed as well.
Students leaving after the first day of this seminar will be confident in their
HVAC electrical control knowledge and armed to go back to their workplace to
immediately apply what they have learned! DISCUSSION TOPICS

Practical Solutions
for Air Distribution
OVERVIEW Many common problems found in HVAC systems are relatively
easy to correct, but are often overlooked. These problems are not electrically
related at all even though many times we can get tricked into thinking they are.
Yet a non-electrical problem can be as frustrating to find and fix as an
electrical one, and may be even more discomforting to the people who have to
live with it. So the second day of this seminar concentrates on the most often
overlooked and ignored problems in HVAC systems – the “V” in “HVAC” – or
ventilation, air distribution and air balancing!
We have all heard the complaints of “too hot”, “too cold”, “not enough air” or
“I feel a draft”. So in this second day of the seminar students will learn how
to solve the problems that cause people to say these things. Students will learn
how to handle a problem like when one area is cooling, but another is not; why
400 cfm per ton is important and why it is used; how refrigerant piping affects
air conditioning performance; how to determine proper blower and duct sizes for
your system; what to do when you have an undersized duct; what causes noise in a
system and the tricks you can use to control it; how to troubleshoot and perform
tests on air handling equipment, exhaust fans and air make-up equipment; how to
properly balance an air system for ideal comfort – and so much more. The primary
goal of this day is to help you minimize the complaints heard from the people
working or living in your building. Once completed, students leaving this class
will have all that they need to handle any complaint that may come their way.
