Day One

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 Electrical Controls & Air Distribution seminar concentrates on overcoming the most common service problems encountered in HVAC systems by teaching students to understand, troubleshoot and test HVAC electrical controls.

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


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


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

Day Two

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 day two of this Electrical Controls & Air Distribution 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!

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

Course delivery details

Live HVAC controls training is not always a viable solution for your organization’s training program. Training schedules, travel costs, and employee health concerns can all stand in the way of offsite instruction. Virtual HVAC electrical training provides an alternative. Led by experienced instructors, live virtual training delivers the same concepts and processes taught in live classrooms through face-to-face video instruction. Virtual classroom interactions, group discussions, and training exercises support successful knowledge transfer and retention. Instructors use pop quizzes to gauge student understanding throughout training, to assess how well employees grasp essential concepts.

Employees can take virtual HVAC controls training courses from any location, as long as they have a computer, webcam, microphone, and internet connection. TPC’s virtual training instructors meet the same rigorous criteria as our offsite instructors and combine years of educational experience with extensive backgrounds in real-world HVAC electrical applications. Virtual training also addresses concerns about employee health, as online courses have built-in social distancing.
