HVACR Technician

This course introduces the student to the career paths and opportunities in the HVACR industry. Professional associations and professional certification are discussed as well. Basic Electricity and motors are fundamental to the success of an HVACR technician. This course is designed to provide the students with the knowledge and technical skills to be applied to advanced courses further in the program as well as job duties in the field. In this course, the student is introduced to electrical safety, electrical theory, and principles. Basic concepts such as types of electrical circuits, circuit components, circuit protection, and the national electric code are discussed in the beginning of this course. As students advance, they will learn about AC and DC voltage supply and application in HVACR, circuit diagrams, and the application of schematics in equipment troubleshooting and repair. In this course, students will learn about Three Phase power supply theory and application, as well as installation and troubleshooting of three phase HVACR systems’ components.

In this course the student is introduced to electrical safety and safety around construction areas. The student will learn to use a variety of electrical, pressure, and temperature measuring devices as well as electrical motors operation, troubleshooting, and repairs. Types of electric motors, motor controls, and troubleshooting will be covered in this course.

Students will learn about the basic components of a refrigeration system and refrigeration systems accessories function, installation, and service, as well as the basic refrigeration cycle. Additional topics covered will be heat transfer, heat transfer methods, and heat content. Introduction to refrigerants will be included in this course, which will give the student a comprehensive understanding of the different types of refrigerants and the impact of refrigerants on the environment.

Students will expand their knowledge of piping and tubing/ soldering and brazing. This course will expose students to the safe and proper procedures of refrigerant handling including refrigerant recovery, recycling, and reclaim. In this course, students will learn about residential air conditioning systems as well as commercial air conditioning systems. The course will expose students to the methods of equipment sizing and election.

This course will cover hydronic heating systems such as hot water and steam boilers. The course will cover different areas, such as sizing and equipment selection as well as identifying the various components used in hydronic heating systems. Students will learn about the installation and service of hydronic systems.

The student will examine air movement and measurement including the understanding of the concepts of climate and weather, humidity, and an understanding of how air movement affects human comfort. The student will study air quality control as measured by temperature, humidity, fresh airflow, pollutants, and chemicals in an enclosed space. Air distribution and ventilation system services are discussed during this course. This course will introduce students to duct fabrication and assembly.

This course will cover heat load calculations, equipment sizing, equipment selection, and equipment installation and service for both residential and commercial setups. Students will be introduced to gas, oil, and electric heating systems as well as control systems that operate in combination with heating systems such as thermostats and humidity and energy recovery systems. Students will practice furnace troubleshooting and tune-up using instruments, including combustion analyzers, monometers, and multi-meters. After completing this course, students will be able to install, troubleshoot, and service heating systems.

Students will practice the proper methods and procedures of installation and troubleshooting for air conditioning systems such as residential central systems and commercial rooftop units. Preventive maintenance will be included in this course.

Students will learn about the mechanical codes that regulate the installation of HVACR systems. Students will be exposed to the proper State mechanical codes as well as the International mechanical codes. The student will be introduced to EPA regulations, recovery requirements, leak detection, and repair. The intent of the course is to get students prepared to take and successfully pass the EPA 608 exam as well as R 410A refrigerant safety.

Students will learn about alternative, non-traditional HVAC systems, such as ductless multi-zone systems, geothermal systems, Heat Pumps, Electric and Oil Heating Systems. Students will learn about the components of such systems as well as installation and service.

Students will learn about the importance of energy conservation as well as the purpose of building controls, protocols, and principles of control system troubleshooting and repairs. Students will learn about the role of information technology in HVACR and building management systems installation and services and components added to an existing system to improve energy conservation.

North American Technician Excellence: is a nationally recognized certification by HVACR contractors. Students review course materials and be prepared to take the NATE Core examination. Topics such as communication skills, mathematics, basic science, personal ethics and conduct, fabrication tools, safety, heat transfer, comfort, electricity, and motors will be covered in this extensive course.

In this course, the student is introduced to commercial refrigeration systems. This class explains system configurations, high-side components, low-side components, and piping. Special refrigeration systems and applications will be discussed to include transportation refrigeration as well as alternative methods.

In this course, the student will build upon the concepts and applications introduced in Commercial Refrigeration I.
