HVAC-R I, Basic Refrigeration Theory90 hoursPrerequisite: NoneStudents learn refrigeration fundamentals, thermodynamic laws and principles of the refrigeration cycle as this is the heart of the industry. Students will also learn and practice the industry standards for cutting, flaring, swaging, and soldering copper tubing. Students will be able to safely install refrigeration service gauges, read system pressures, and remove gauges from working systems. Students will also practice procedures for pressure checking systems, evacuating, and charging systems. Students must provide their own basic hand tools.
HVAC-R II, Basic Electrical Theory90 hoursPrerequisite: NoneStudents learn basic electrical theory as it applies to the HVAC-R industry. An understanding of electrical motor operation will allow students to work on complete air conditioning systems. Students also learn to read electrical schematics and ladder diagrams. Emphasis on building electrical circuits, installing electrical components, and troubleshooting working systems will also be taught. Students must provide their own basic hand tools.
HVAC-R III, Home Heating and Cooling90 hoursPrerequisite: HVAC-R I & IIStudents will learn the principles of combustion for gas and oil as used in home and light commercial systems. Electric furnaces will also be taught. In the shop students will be able to work “total” heating and cooling systems.Strong emphasis on electrical as it relates to these systems will be presented on actual equipment and interactive computer programs. Students must provide their own basic tools.
HVAC-R IV, Commercial Refrigeration90 hoursPrerequisite: HVAC-R I & IIStudents will work with systems and accessories to accomplish a deeper understanding of the refrigeration cycle. With the aid of interactive computer programs, students will be able to read single and three phase commercial electrical schematics, troubleshoot them, and apply these principles in the shop. Installation problems and troubleshooting controls and systems are also covered.
EPA Review and Exam8 hoursPrerequisites: HVACR-I or higherStudents will review information and practice procedures to prepare for the EPA examination. The exam will be given during the second night of class. Course cost includes exam fee; however students must have separate checks for tuition and the exam fee.
