Core Courses

Safety and Craft Skills

This course encompasses classroom and lab work study of introductory safety and craft skills. Areas of study include basic safety, construction math, hand and power tools, basics of construction drawings, rigging, communication skills, employability skills, and material handling. Department of Labor and Occupational Safety and Health Administration (OSHA) regulations applicable to general industry are also covered.

Applied Math for HVAC Technicians

This course covers basic mathematical operations, such as addition, subtraction, multiplication, and division of whole numbers, decimals, and fractions. Students will learn basic algebra, geometry, and trigonometry concepts as they relate to refrigeration and air conditioning.


Introduction to Electricity (DC-AC)

This course provides students the basic concepts of electricity necessary to operate instruments and equipment related to air conditioning and refrigeration. Students will learn about direct current (DC) circuit theories, parameters, and devices. Students will also study alternating current (AC) circuit theories related to capacitors, contactors, relays, and transformers. Finally, they will review the concept of inductance and its effects on alternating current sources.

Introduction to Refrigeration and A/C

In this course, students will learn about the basic refrigeration and air conditioning cycles, thermodynamics, pressure-enthalpy diagrams, and major refrigeration and air conditioning components and systems. This course focuses on refrigerant properties, refrigerant transferring, refrigerant evacuation and recycling, refrigerant pressure, vacuum pumps, the effects of heat on refrigerants, environmental heat measurements, heat transfer, sensible heat and latent heat, states of matter, and gas laws. It also covers the pressure-temperature relationship of liquids and vapors, the pressure-temperature relationship of refrigerants, compressor construction, condensers, evaporators, refrigerant metering devices, refrigerant characteristics, and lubrication.

Refrigeration and A/C: Residential

In this course, students will learn about the residential refrigeration and air conditioning cycles. The topic of refrigeration will include domestic refrigerators and freezers, defrost methods, and frost-free systems. This course also covers different types of A/C units, compressor types and operation, hot gas and electric heat defrost, condensate disposal, room air-conditioner cycle, and the operating characteristics of air conditioning units. Finally, students will examine psychometrics, how to measure relative humidity, and how to use psychometric charts.

Refrigeration and A/C: Commercial

In this course, students will learn about the commercial refrigeration and air conditioning cycles. The topics covered include air conditioning and refrigeration equipment sizing and selection, flow controls, pump down systems, defrost cycles (hot gas and electric), and head pressure controllers. Students will also select and install high, medium, and low temperature refrigeration systems.

Heat Pumps and Related Systems

In this course, students will discuss heat pump theory, diagnostics, and repair procedures, as well as other related systems. Students will also examine the differences between heat pumps and straight cooling units. In addition, they will calculate the British thermal units (BTUs) for heat pump systems. Finally, they will learn how to diagnose and install four-way reversing valves and defrost control boards.

Electrical Instrumentation: Lab

This course is designed to apply the circuit theories discussed in the Introduction to Electricity course. Students will use measuring instruments to tests the theories and properties of electrical (AC and DC) circuits. The course will focus on diagnosing and troubleshooting breakers, fuses, and safety switches. Finally, students will troubleshoot contactors, relays, capacitors, transformers, and other electrical devices.

Prerequisite: HVA1400

Mechanical Instrumentation: Lab

This course will teach students the basic principles of mechanical refrigeration and air conditioning equipment. Students will also learn about the tools, equipment, and techniques used in the refrigeration and air conditioning industry. In addition, students will discuss general security procedures and different equipment and tool conservation techniques.

Prerequisite: HVA1500

Residential Equipment: Lab

In this course, students will diagnose, maintain, install, and repair residential air conditioning and refrigeration systems. Students will learn safety procedures, how to install gauges, how to take temperature and pressure measurements, how to read and measure relative humidity, and how to test for refrigerant leaks. Finally, students will troubleshoot mechanical and electrical problems in air conditioning and refrigeration systems.

Prerequisite: HVA1600

Commercial A/C Equipment: Lab

In this course, students will learn how to test, maintain, install, and repair commercial refrigeration and air conditioning systems. This includes electrical and mechanical troubleshooting of high, medium, and low temperature refrigeration systems, such as ice machines, walk in coolers, and display cases, coolers, and freezers.

Prerequisite: HVA1700

Environmental Protection Agency (EPA) Laws and Regulations

In this course, students will learn about the laws and regulations applicable to the use and handling of refrigerants. In addition, they will study Florida laws, OSHA laws and regulations, HVAC licensing requirements, and federal and state laws applicable to refrigeration and air conditioning. Finally, the course will prepare students to take the 608 EPA (Environmental Protection Agency) certification exam.
