Course Description

There is a shortage of trained technicians because the older techs are retiring at a much faster rate than new technicians are entering the field. This creates an ever increasing need for HVAC technicians for at least the next 10 years. Think about this - HVAC jobs cannot be shipped overseas and are nearly recession proof... you will never be out of work.

The HVAC Technician Course prepares you for entry-level employment as an HVAC Technician. HVAC Technicians work as mechanics and/or installers. The HVAC technician training includes theory, electrical, and diagnostics covering commercial refrigeration, gas heat, heat pumps, and air conditioning.

This course includes hundreds of videos, supplementary information, and simulations not found anywhere else. After completing this course, you will have the knowledge you need to land your first job in the HVAC career field and be on your way to earning a living that will support you and your family.

The HVAC jobs market is growing 21% faster than the national average... you'll never be out of work.

How Does This Course Work?

  • Reading assignments are short. 3-5 pages per assignment... easy evening read.
  • Videos and supplementary information reinforce each module of instruction.
  • Post questions and have discussions in the online classroom forum.
  • Attend or review our live training events.
  • Request live one-on-one training for areas where you need help.
  • Apply your knowledge with our online HVAC simulation.
  • Test your knowledge with end of module exams.

Please note: Course of study may be completed earlier than indicated.

Outcome

Upon successful completion, The HVAC Technician Course prepares you for entry-level employment as an HVAC Technician. HVAC Technicians work as mechanics and/or installers.

Outline

Module 1: Heat, Temperature and Pressure
This unit covers temperature, methods of measuring and transferring heat, and discussions pertaining to molecular motion, sensible heat, latent heat, and specific heat. It also discusses atmospheric pressure and test instruments such as gauges used to measure pressure.

Module 2: Matter and Energy
This unit defines matter, mass, density, specific gravity, and specific volume. Gas laws, including Boyle’s law, Charles’ law, the general law of perfect gas, and Dalton’s law, are stated. The broad subject of energy is covered, as well as energy in heat and in magnetism. The measurement of energy in horsepower, watts, and British thermal units is discussed

Module 3: Refrigeration and Refrigerants
This unit includes a history of refrigeration and a basic discussion of the refrigeration process. Using water and refrigerants as examples, the temperature/pressure relationship is discussed and is followed by a description of the four major refrigeration components: the evaporator, compressor, condenser, and metering device

Module 4: General Safety Practices
Safety is discussed in great detail throughout the book, but this unit provides safety precautions necessary when working with pressure vessels and piping, electrical hazards, heat, cold, mechanical equipment, heavy objects, and chemicals.

Module 5: Tubing and Piping
This unit covers basic piping operations and techniques, including cutting, bending, soldering, brazing, swaging, and flaring. General information regarding tubing and piping materials, such as types, sizes, insulation, and line sets, and environmental issues is also provided. Soldering and brazing procedures are presented in detail, along with procedures for properly setting up and storing torches used for air-acetylene and oxyacetylene applications.

Module 6: Leak Detection, Evacuation, and System Cleanup
Module 6 presents information on leak detection, system cleanup, and system evacuation. This unit includes the purpose and theory of evacuation and covers as well measuring the vacuum, the vacuum pump, deep vacuum, multiple evacuations, leak detection while in a vacuum, and removing moisture with a vacuum. It also covers general evacuation procedures, systems with Schrader valves, gauge manifold hoses, system valves, using dry nitrogen, and refrigerant recovery and recycling.

Module 7: System Charging
Information on charging refrigeration systems is provided in this unit, including vapor and liquid refrigerant charging, weighing refrigerant, and the use of charging devices.

Module 7A: Recovery, Recycling, Reclaiming, and Retrofitting
