Principles of electricity as required by HVAC technicians including proper use of test equipment, A/C and D/C circuits, and component theory and operation are taught in this course.

This is an introduction to the refrigeration cycle, basic thermodynamics, heat transfer, temperature/pressure relationship, safety, refrigeration containment and refrigeration components.

This course introduces students to basic hand tools and refrigeration tools that are commonly used in the refrigeration and air conditioning industry stressing proper application, use and care of these tools. In addition, tubing operations are performed on copper tubing and fittings. These are correctly connected by mechanical methods using acetylene and oxygen welding equipment. Safety techniques are carefully observed and employed in all areas of instruction.

This course is the study of the properties of air and results of cooling, heating, humidifying or dehumidifying; heat gain and heat loss calculations including equipment selection and balancing the air system.

This course covers theory, sequence of operation, components and repair, electrical schematics, and troubleshooting electronic components in air conditioning and refrigeration. Emphasis is placed on safety for the electrical, mechanical, and sealed systems.

This course is the study of the procedures and principles used in servicing heating systems including gas fired furnaces and electric heating systems.

This is a study of components, applications, and installation of air conditioning systems with capacities of 25 tons or less.

This course is advanced electrical instruction and skill building in installation and servicing of air conditioning and refrigeration equipment, including detailed construction in motors and power distribution, motors, motor controls, and application of solid state devices.

Theory of and practical application in the maintenance of commercial refrigeration; medium and low temperature applications and ice machines are introduce in this course.

A study of components, accessories, applications, and installation of air conditioning systems above 25 tons capacity will be presented.
