Purpose of Seminar:

This course was created to bring students up to speed in their knowledge of HVAC electrical controls and air distribution systems as quickly, efficiently and safely as possible. It includes discussions on skills improvement and is specifically designed for anyone who is responsible for keeping comfortable working or living conditions in their buildings. It provides a practical, real world HVAC education taught by instructors who have actually spent time in the field doing the work. Novice technicians receive a comprehensive overview of HVAC electrical and air distribution best-practices and experienced technicians use it as great refresher course for continuing education or to learn a few new ideas or tricks of the trade. Whether you are blowing heated or cooled air, helping you keep the temperature consistently comfortable for the people in your building is what this course is all about. Students’ specific needs and concerns are also addressed during the class so that they can go back to their workplace and immediately apply what they’ve learned.

After attending this course, students will be able to prevent system downtime, improve efficiency and safety, and fix problems they’ve never been able to fix before. Overall, this HVAC training program is designed to teach students how to “control” their electrical controls and use fundamental air distribution principles for achieving consistent HVAC comfort and efficiency in buildings, plants and facilities.

Discussion Topics

DAY 1 - HVAC Electrical Control Basics, Troubleshooting & Testing

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 one 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. Discussion topics for this segment of training include:

  • Basic Electricity
    • Basic electricity & Ohm’s Law
    • Meters & tools for taking electrical measurements
    • Electrical circuits: series & parallel

  • Control Circuits
    • Schematics
    • Ladder Diagrams
    • Developing Wiring Diagrams

  • Controls
    • Overloads
    • Relays
    • Contactors
    • Control Transformer
    • Starting Relay
    • Defrost Timer
    • Thermostat
    • High Pressure Control
    • Low Pressure Control
    • Oil Pressure Control

  • Troubleshooting
    • General Troubleshooting Techniques
    • Common Problem Areas
    • Commercial Air Conditioning
    • Heat Pump Control
    • Pump Down Cycle

DAY 2 - Practical Solutions for Air Distribution

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 in the second day of this training program we’ll help you eliminate the complaints of "too hot", "too cold", "not enough air" or "I feel a draft", by concentrating on the most often overlooked and ignored problems in HVAC systems – the "V" in "HVAC" – or ventilation, air distribution and air balancing! Discussion topics for this segment of training include:

  • Determining and Improving Air Flow
    • 400 cfm per ton
    • How many square feet per ton?
    • Air mixture at the cooling coil

  • Exhaust Air
    • Positive pressure
    • Negative pressure

  • Make-Up Air
    • Positive pressure
    • Negative pressure
    • Conditioning the "make up" air

  • Troubleshooting the Air Distribution System
    • Temperature difference across the coil
    • Balance in the system
    • Short cycling
    • Duct sizing
    • Noise
    • How to use a Ductulator
