Curriculum for HVAC-R, an applied science, lends itself to presentation via digital technology, and HVAC-R instructors, who tend to be adept at using technology, are good at using the medium.

Classroom based HVAC-R trainers use charts to teach subjects such as temperature/pressure relationships; cut aways to teach about the functions of mechanical equipment; and schematics to teach about electrical circuits. Presentation software allows dramatic enhancements to these aids, which make them more interesting and effective for both classroom and on-line students . These aids incorporated into on-line HVAC-R courses, such as AirCon Academy (www.www.airconacademy.com) also provide the student the opportunity to use the tools at their own pace.
