Provides students with the knowledge and skills necessary for entry-level employment in Refrigeration service and maintenance.
Students are required to pass one (1) state recognized certification and four (4) nationally recognized certification exams during the program. All courses must be completed with a minimum “C” grade to receive the certificate.
Note: HAC 102, HAC 105, HAC 120, HAC 162, and HAC 164 are prerequisites for HAC 237 Basic Refrigeration I.

Discusses the structure of matter, movement, electrons, conductors, insulators, direct and alternating currents, and electrical units of measurement. Students will also study electrical circuits and measurements, Ohm’s law, series and parallel circuits, and electrical power. Also includes magnetic fields, inductance, transformers, capacitance, impedance, sine waves and using electrical measuring instruments.
Discusses types of automatic control devices that respond to thermal change, the bimetal device, control by fluid expansion, the thermocouple and electronic sensing devices. Covers space temperature controls (both high and low voltage), sensing temperatures of solids, pressure-sensing devices, oil-pressure safety controls, air-pressure controls, devices that control fluid flow, and maintenance of mechanical and electromechanical controls.
Covers control terminology, applications and electronic control circuits. Pneumatic controls and direct digital controls are also explored, along with programmable thermostats. Also covers procedures for troubleshooting basic and complex circuits, thermostats, and high-voltage circuits controlled by thermostats. Describes procedures for measuring amperage and voltage in low-voltage circuits and discusses pictorial and line diagrams.
Discusses types of electric motors, along with starting and running components and characteristics, motor speeds, and power supplies. Specific topics also included are single and split-phase motors, the centrifugal switch, electronic replay, capacitor start motors, capacitor run motors, permanent split capacitor motors, shaded pole motors, single phase hermetic motors, positive temperature coefficient motors, and variable speed motors. Includes discussions of various characteristics and insulations, bearings, mountings, and motor drives.
Discusses mechanical and electrical motor troubleshooting. This includes drive assemblies, belt tension, pulley alignment, open and shorted windings, shorts to ground, capacitor problems, wiring and connectors, and troubleshooting hermetic motors.
Mandatory course designed to provide EPA nationally recognized certification required for purchasing, removing and recycling refrigerants. This class is a 12-hour training session with the certification test upon completion and is taught by a registered proctor. Required to attain degree.
