The National Institute for Service Technicians offers a comprehensive training program in heating and air conditioning repair and maintenance and covers:

• Basic principles of refrigeration and air conditioning
• Understanding and repair of electrical systems
• Major components, testing equipment, troubleshooting procedures
• Refrigerant and refrigerant handling
• EPA certification supplemental program is available

Our heating and air conditioning training program is designed to train entry-level technicians to diagnose, service and repair heating and cooling systems. Classrooms and labs focus on the individual student, with no more than 12 students per class. That means lots of “hands-on” training for each and every student.

THE PROGRAM

• A/C 100 FUNDAMENTALS OF REFRIGERATION
  The basic fundamentals that apply to mechanical refrigeration. The functions of compressors, condensers, receivers, evaporators, metering devices, basic cycle controls, accessories and refrigerants.


• A/C 101 ELECTRICITY FOR AIR CONDITIONING
  This course deals in detail with both basic fundamentals of electricity and advanced electricity. This will include electron theory, OHM's law, power equations and Kirchoff's law relating to resistance, current, voltage and power in series and parallel circuits. The course will also include single-phase meter theory and electrical components used in A/C technology.


• A/C 102 ELECTRIC HEAT AND COOL
  This course combines A/C 100 and A/C 101 theory in "hands-on" wiring and running of actual units. Students will use various wiring diagrams to wire A/C units. Ambient charging procedures, refrigerant recovery and evacuation will also be taught.


• A/C 105 HEAT PUMPS
  This course is an introduction to heat pumps and their operation. It will cover various defrost methods including time temperature, demand, air switch and other defrost controls. Superheat charging is also introduced.


• A/C 104 WELDING AND ELECTRIC HEAT
  Brazing methods are learned and practiced in this course, as well as the proper method for a compressor change-out. This course also includes wiring single and multiple electric heat systems.


• A/C 115 TROUBLESHOOTING
  This advanced course will cover recommended service and diagnosis procedures for air conditioning systems. This will include general troubleshooting procedures for both mechanical and electrical systems.
