In order to work in the HVAC industry, courses in a program must cover topics involving air conditioning and heating. Courses teach students how to install and maintain heating and cooling systems in residential and commercial settings. Types of systems may include air conditioning units, boilers and other HVAC units. Students learn through academic coursework and field training.
HVAC courses also provide students with an opportunity to learn about refrigeration systems. Students in these courses learn about assembling systems, handling refrigerants, identifying materials and properly using tools. An emphasis may be placed on specific refrigeration systems, such as compressors, condensers, evaporators and equipment.
Before graduating and beginning a career in the HVAC industry, courses teach students about the specific codes and ordinances in a state. HVAC courses ensure that students adhere to these codes and that heating and cooling systems remain environmentally friendly. Being able to install energy efficient systems may also open career possibilities, as focus is placed on improving the environment.
As heating and cooling systems become more technology advanced, students must have an understanding of computer applications. In addition to operating these computer programs, students also must be able to explain computer applications to individuals. HVAC computer applications are used to calculate heat loss and gain, automatic operation and sustaining energy.
HVAC courses must also teach students how to troubleshoot various HVAC systems and equipment. Students learn to go through a series of processes in order to discover why a system or equipment is not operating properly. Opportunities are available for students to improve their communication and interpersonal skills to discover any mechanical issues.
