Course No. Course Title Credits
HAC 151 Introduction to Refrigeration 4
This is the first of two (2) courses in refrigeration. The course familiarizes its students with safety procedures for the use of tools and materials; basic principles of operation of compressors, condensers, and evaporators; control of systems; and performance of standard tests.
HAC 152 HVAC/R Electricity I 3
This course introduces students to AC and DC circuits, interpretation of electrical schematics, use of electrical test equipment, regulation of electrical systems, and installation of electrical apparatus in accordance with the National Electrical Code.
HAC 153 Pipefitting 3
The fundamental tools, equipment, and procedures used in pipefitting are covered in this course. Matching system components and making proper connections are studied, planned, and practiced. Applications to domestic water distribution and hot water production will be discussed. The student will also be introduced to duct work fabrication.
HAC 154 Print Reading and Codes for HVAC 3
HVAC blueprint reading is reviewed in relation to each of the curriculum’s systems: heating, ventilation, air conditioning, and plumbing. The symbols and specifications pertaining to each system are explained so that they can be followed in the system’s installation and repair. Overview of National Codes and Standards will be discussed.
HAC 155 HVAC/R Electricity II 3
This course is a continuation to HVAC/R 152.  Motor controls used in HVAC systems will be reviewed with emphasis on reading of electrical prints, wiring, and troubleshooting of these systems.  An overview of PLC controls will be also covered.
Prerequisite: HAC 152
HAC 156 Air Conditioning Systems 4
This course exposes the student to the design, operation, and installation of air conditioning systems. All of the systems’ components are studied in relation to their compatibility for ventilation, air handling, and climate control. Calculation formulas are studied, appropriate systems are discussed, and components are arranged to meet specifications and to comply with codes.
Prerequisite HAC 151
HAC 251 Heating System Design and Installation 4
The study of gas, fuel oil, electric, and coal heating systems includes the calculation of heat requirements, production, circulation, and loss. Various boiler units and their related accessories are evaluated for fuel choice, efficiency, and installation. Heating needs within a variety of climate zones and formulas to calculate heat loss are studied.
HAC 252 HVAC Controls I 4
The regulation of residential HVAC systems is the focus of this course. All HVAC controlling units from circuit breakers to thermostats are reviewed. Both operational theory and installation are covered for all controls.
Prerequisite HAC 152
HAC 253 Hydronic Heating Systems 4
The boilers and furnaces of forced hot-water heating systems are studied in this course, along with their distribution and return piping. The systems are evaluated for their efficiency as well as for their cost for components, installation, and operation.
Prerequisite HAC 153
HAC 254 Refrigeration Applications Commercial Systems 4
This course stresses the refrigeration systems used to regulate air temperature, humidity, and circulation. Both stationary and mobile units are examined in a variety of large, walk-in applications. Proper handling of refrigerants is stressed in accordance with federal regulations.  Calibration, testing, and troubleshooting of all components are covered. Electrical, mechanical, and material safety is emphasized.
Prerequisite HAC 151, HAC 156
HAC 255 HVAC Controls II Commercial 4
The regulation of large-scale, commercial HVAC systems is the focus of this course. Operational theory and compatibility of controls to specific systems are the course’s main concentration. Both electric and computer controls are integrated into single and multi-zone air-handling systems. An overview of pneumatic controls will be discussed.
Prerequisite: HAC 252
HAC 256 Applied HVAC Principles and Applications 4
This course is intended to re-exam and emphasize mechanical skills and diagnostic techniques and to apply them to principles and theories learned in previous modules. Students are expected to hone the specific skills to prepare them for entry-level positions upon graduation.
HAC 257 Internship 4
This work experience is designed to expose the student to an actual industrial, commercial, or clinical environment. Students are placed into a contracted facility after they have completed 30 credit hours, have a 2.0 GPA, and have met all other program prerequisites and academic requirements prior to their final spring semester. The student is expected to adhere to all policies and regulations associated with their work term facility. Students will work on projects selected to expose the student to “live” work situations, while building upon the student’s knowledge, skill and attitude as an entry-level technician and will be used to grade the student’s performance for the course. The schedule for meeting the requirement of this experience will be arranged between the student, faculty member and internship site. (No compensation.) (200 hours)
HAC 258 Cooperative Educational Experience 4
This work experience is designed to expose the student to an actual industrial, commercial, or clinical environment. Students are placed into a contracted facility after they have completed 30 credit hours, have a 2.0 GPA, and have met all other program prerequisites and academic requirements prior to their final spring semester. The student is expected to adhere to all policies and regulations associated with their work term facility. Students will work on projects selected to expose the student to “live” work situations, while building upon the student’s knowledge, skill and attitude as an entry-level technician and will be used to grade the student’s performance for the course. (Compensation) (200 hours)
