Essential Information
Although some heating, ventilation and air conditioning (HVAC) professionals receive their training on the job or through 3- to 5-year apprenticeships, many learn their trade through 6-month to 2-year HVAC certificate or associate's degree programs. These programs include air conditioning courses and are usually offered at 2-year technical colleges or trade schools.
Here are common concepts found in air conditioning classes:
- Diagnostics
- Technology
- Building systems
- Basic electricity
- Industrial controls
- Customer service
- Communication
HVAC students can go on to become HVAC installers, technicians or project coordinators. Some employers look specifically for industry-certified HVAC professionals and some states require licensing, though specific requirements vary. Those technicians who handle refrigerants - like those found in air conditioners - must be certified by the U.S. Environmental Protection Agency by passing at least one of three possible certification exams.
List of Courses
Basics of Air Conditioning Course
A basic air conditioning course teaches students introductory concepts for air condition systems in residential and commercial buildings. This is a course that is typically taken at the onset of an HVAC degree or certificate program. Specific topics of study may include air conditioning systems, air conditioning processes, fans and general ventilation. This course may also touch on concepts of noise control, HVAC laws and air quality.
Air Conditioning Design Course
An A/C design course reviews the process of air conditioning and the core components of HVAC systems. Students learn through hands-on and exercises. Topics include trouble-shooting A/C design programs, evaluating HVAC systems, proper equipment selections and techniques in ductwork design. This course provides students with skills in determining HVAC system efficiencies for residential and commercial buildings.
Refrigeration Course
A refrigeration course can be found within an air conditioning program, since HVAC professionals often work with cooling units and refrigerant. Specific topics of study in this class include refrigeration controls, laws and regulations for refrigerant fluids and safe refrigerant handling. Students also learn about components such as condensers, evaporators and compressors, as well as how to handle leaks, parts replacements and metering devices.
Residential Air Conditioning Course
In a residential air conditioning course, students study installation, operation and maintenance techniques for A/C units found in single-family homes and living facilities. Specific topics of study include mechanical repairs, air treatment, electrical repairs and home duct work.
Commercial Air Conditioning Course
Commercial air conditioning focuses on A/C units in large-scale buildings such as business offices, apartments or hotels. Topics covered are similar to a residential air conditioning course, with the specifics concerning large-scale buildings. Things like cooling zones, rooftop heating, controlling capacity and psychometrics are also studied. Students learn through lecture and practical exercises.
