HVAC Controls & Air Distribution On-Site Training

This on-site training class is also available as Public Schedule Seminar.

Maximize HVAC comfort and efficiency, and keep the people in your building happy!
Day 1 – Control Basics, Troubleshooting & Testing
Day 2 – Practical Solutions for Air Distribution

Course Description/Agenda

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 Competencies & Learning Objectives:

  • 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
