HVAC/R Program Courses
Fundamentals of Electricity
This HVAC/R class provides The Refrigeration School students with basic electrical understanding from an elemental stage through troubleshooting. Trainers are used to teach schematic wiring as well as test meter usage along with all the safety processes associated with handling electrical systems such as grounding and energized circuits. Students will work with dual voltage systems commonly found in HVAC/R equipment.
The foundation for control circuit wiring and high voltage wiring are discussed and students will put their knowledge to use while working with the trainers. The training material in this HVAC/R class includes information on multiple types of test meters and their proper use, electrical devices, control devices, and troubleshooting. A study of single phase and three phase motors round out the students’ understanding of basic electrical principles.

Fundamentals of Refrigeration
In this HVAC/R class, The Refrigeration School students are introduced to the refrigeration cycle through class lecture and observing operating equipment. The material in this class is mechanical in nature and is limited to the mechanical and physical properties of refrigerants and the refrigeration cycle. The equipment in this class is used to safely demonstrate the varied states of refrigerant as it cycles through the system. The student will be introduced to many of the tools associated with the refrigeration industry such as: manifold gauge set, vacuum pumps, service wrenches, charging, and recovery equipment. The safety programs in this class will provide students with details on being in close proximity to rotating machinery and refrigerant handling. The class is also designed to familiarize the student with details on the mechanical troubleshooting process.

Comfort Systems – Residential
This HVAC/R class offers experience with residential split systems, packaged heat pump systems, air conditioners, gas furnaces, and evaporative coolers. The Refrigeration School students are tasked with building schematics for air conditioning/heating systems and wiring the same systems having only the components of the system as reference. A further study of mechanical and electrical troubleshooting turns more hands-on in this class as students see the equipment come to life by their own hand. Gas piping, sizing, and installation are studied as it applies to furnace operation.

Comfort Systems – Commercial
This HVAC/R class offers a more technical approach to studying the concepts of indoor climate control. The Refrigeration School students are tasked with safely removing and replacing components within residential and commercial HVAC systems such as fan motors, fans, electrical components, and compressors. Recovery and charging of refrigerants are an integral aspect of this class and students will apply their lessons to real equipment to round out the experience. Students will study brazing techniques using oxy/acetylene equipment and are required to put their knowledge to use on multiple tasks designed to enhance understanding of working within the confines of an HVAC unit. Refrigerant piping manipulation is introduced for study using hands-on techniques as students gain an overall familiarization of HVAC equipment. The opportunity to study and test on R410a and automotive air conditioning is provided in this class; successful students will achieve an R410a safety certification and EPA section 609 certification. An introduction to air balance and the associated equipment are also included for this class.

Refrigeration Systems and Practices
Students will learn to maintain, monitor, and manage residential and commercial grade walk-in refrigerators and freezers. A study of commercial grade ice makers such as: a flaker, cuber, and nugget type units provide an intense look at low temperature refrigeration equipment. The Refrigeration School students will be required to change out a compressor, service and/or repair critically charged systems to enhance their overall understanding of mechanical and electrical troubleshooting. A variety of specialty tools related to equipment studied in this class will be introduced to round out the total experience.

Advanced Troubleshooting Techniques
The HVAC/R class introduces the operation and maintenance of reciprocating liquid chillers and stands as a review of the knowledge The Refrigeration School students have attained through previous courses. Electrical troubleshooting takes on a new intensity in this class as students are exposed to the E-STAR Trainer. The E-STAR Trainer is equipment developed by The Refrigeration School to teach and hone electrical troubleshooting skills. A thorough study of mechanical troubleshooting and schematic wiring will raise the student to the level of technician. The opportunity to qualify for EPA section 608 certification is provided during this class. The overall goal of this class is to ensure students have attained the required skills to be successful entry level HVAC/R technicians.
