Beginners can read the basics of HVAC systems on the blog portion of the Central Heating & Air Conditioning website. For those seeking to obtain a more in-depth understanding of how HVAC systems work, Industrial Training School offers a distance-learning education course titled HVAC for Beginners, as of 2015.
The HVAC for Beginners course is designed to help students decide whether a career working with HVAC systems is the right choice for them. Some topics covered during the course include the fundamentals of refrigeration, the importance of refrigerants, refrigerant recovery and air conditioning. Students learn about the history of refrigeration as well as key vocabulary terms used in the HVAC industry needed to communicate with other HVAC professionals. They learn to identify the common refrigerants and how to handle them. Students also discover ways to recycle refrigerants and the dangers of handling refrigerants in improper ways.
Those who enroll in the course also learn how to identify the main components of an air conditioner. They study air quality and humidification as well as the different types of indoor heating, such as gas heating, oil furnaces and wood furnaces. The course, which students complete at their own pace but within a year, requires a textbook featuring color sketches and images designed to facilitate the learning process.
