What Are the Courses in an Online HVAC Training Program?

To enter the heating, ventilation and air conditioning (HVAC) field, one must have knowledge of several core technical areas. An online HVAC training program may be especially well-suited to working professionals who don't have time to attend traditional classes. Learn more about the core courses of such programs here. Schools offering Heating Ventilation & Air Conditioning degrees can also be found in these popular choices.

Online HVAC Training - An Introduction

In an HVAC training program, students take courses and perform hands-on work that introduces them to the mechanics of HVAC systems. Students who choose online HVAC programs must rely on an employer or another HVAC technician to supervise their hands-on learning. An online training course from a university in North Dakota defines several standard core courses for HVAC training programs which are discussed below.

Most air systems are operated through electricity, so HVAC students must learn how to wire systems together and to connect those systems to electrical sources. Courses begin with basic theory and introductions to electrical terminology, circuitry, currents and symbols. Students learn about wiring techniques and wire loads.


The heating portion of an HVAC training program is often the most complicated; therefore, a lot of time is usually devoted to it. Students learn how to draft and vent the various types of heating systems. Heating courses aim to explain how the different types of heat pumps work. Their goal is also to teach students how to install and repair parts for each type of system listed below:

  • Oil heat
  • Gas heat
  • Boiler heat
  • Hydronic geat

Refrigeration and Air Conditioning

Since the principles of both are closely linked, an online HVAC program is likely to contain a core course on both refrigeration and air conditioning. Such a course introduces you to the basics of cooling systems, including the concepts of compression and condensation. Students have opportunities to learn how to control liquids in these cooling systems through evaporation and piping.

Once training is completed, it is recommended that students become certified. Two popular certification exams are the Industry Competency Examination (ICE) through the Air Conditioning Refrigeration Institute or the Core Examination through North American Technician Excellence (NATE).
