Prepares students for positions in the heating, air conditioning, and refrigeration industry. Graduates will be prepared for entry-level positions as service technicians, building maintenance technicians, equipment assemblers, and start-up residential and light commercial installers. Students will participate in work-based training through realistic training activities on campus.
Included in this program are academic courses in communication, quantitative reasoning, and social sciences that provide knowledge and abilities that enhance personal development and serve as a foundation for technical skills.
This program is approved as an HVAC/Refrigeration (06A) specialty electrical training program in the state of Washington.
Upon successful completion of the program, graduates applying to become an HVAC/Refrigeration (06A) specialty electrician can be credited with an estimated 1,178 hours of work experience. This program is not applicable to any other electrical specialty or sub-category.
Students pursuing an AAT or AAS-T degree must complete all college degree requirements prior to graduation. This includes courses that meet the requirements for diversity, computer literacy and the capstone project. Students are required to pass seven nationally recognized certification exams during the program. All courses must be completed with a minimum “C” grade to receive the certificate.
Note: HAC 102-167 are prerequisites for Heating & Refrigeration.
Highly Recommended Class: CAS 105, Keyboarding 3CR.

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.
Serves as an introduction to the concepts of direct digital controls (DDC). The course is a generic approach to understanding DDC terminology, the fundamentals of today’s new building control systems, how they work, features and troubleshooting.
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.
When it comes to HVAC/R electrical, “green” means maximizing the energy efficiency of existing equipment, specifying the most efficient systems available for the application and the available budget using renewable and sustainable fuel sources, and conserving water. This course discusses those items, along with the core knowledge of energy management and analysis, green heating, ventilation, air conditioning, refrigeration, electrical generation and consumption, and “green” plumbing.
Covers controls, thermal physics, electric heating, and equipment for residential and light commercial heating system installation and servicing with emphasis on electric heating and gas heating.
Teaches students to troubleshoot and repair electric heating and gas-burning appliances. Also covers thermal physics and equipment for heating-system analysis and efficiency. This is a hands-on class using live projects.
Covers controls, thermal physics, and equipment for residential and light commercial heating system installation and servicing with emphasis on oil and hydronic heating.
Teaches students to troubleshoot and repair oil and hydronic heating equipment. Also covers thermal physics and equipment for heating-system analysis and efficiency. This is a hands-on class using live projects.
Covers troubleshooting and repair of refrigeration equipment, thermal physics, equipment for refrigeration systems analysis and efficiency.
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.
Introduction to controls, thermal physics and equipment for air conditioning system installation and servicing.
