Purpose of Seminar:
By the end of this seminar students will have a new confidence in identifying and
fixing their own electrically related problems in their HVAC systems and will be
able to go back to their workplace and immediately apply what they have learned.
Who should take this course?
This course is designed for anyone who works on HVAC systems. Attendees come from
a wide variety of industries, skill-levels, company sizes and educational backgrounds.
This course is especially beneficial for non-electricians in cross-training programs
and for those 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!
People who will benefit from this seminar include:
- HVAC Technicians
- Refrigeration Technicians
- Boiler Operators
- Building & Facility Maintenance Personnel
- Multi-craft & Cross Training Personnel
Working in:
- Commercial Buildings
- Schools
- Hospitals
- Research Facilities
- Government Buildings
- Office Buildings
- Data Centers
- Multi-Family Buildings
- …or any other facility with an HVAC system!
Learning Objectives
Upon completion of this course, students will receive a training certificate and .7
Continuing Education Units indicating that the student understands:
- How to Identify a problem as being Electrical, Mechanical or an Air Distribution issue
- The basics of electricity as it applies to HVAC systems
- The electrical circuits and components used in HVAC Systems
- How to read HVAC ladder diagrams
- How to read wiring diagrams
- How to troubleshoot line voltage and low voltage problems
- What the most common electrical problems are in HVAC systems and how to fix them
- How to troubleshoot the more uncommon HVAC problems
- How to properly test operating controls and safety controls
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!
Course Outline / Agenda
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 as it relates to HVAC
Systems and how common series and parallel circuits are used in them. They will learn how
to test and troubleshoot both line voltage and low voltage in their systems. They will
learn how to identify an electrical problem from a non-electrical problem and will gain
an overall understanding of the electrical circuits and controls they encounter every day,
and more…
