HVACR Courses

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. 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 system’s accessory 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 on the different types of refrigerants and the impact of refrigerants on the environment. This course will expose students to the safe and proper procedures of refrigerant handling including refrigerant recovery, recycle and reclaim.

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

The student will examine air movement, measurement including the understanding 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 service are discussed during this course.

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. Completing this course, students will be able to install, troubleshoot, and service heating systems.

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 selection. Students will practice the proper methods and procedures of installation and troubleshooting for air conditioning systems – residential central systems and commercial rooftop units. Preventive maintenance is included in this course. Students will learn about alternative, non-traditional HVAC systems, such as ductless multi-zone systems and geothermal systems. Students will learn about the components of such systems as well as installation and service.

Students will learn about system installation and startup. This includes gas pipe, drain line, electrical and sheetmetal. The student will learn to use a variety of electrical, pressure and temperature measuring devices and will use sheetmetal tools necessary for fabrication and assembly of ductwork. 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. Students will be introduced to EPA regulations, recovery requirements, leak detection, and repair. Students will prepare to take and successfully pass the EPA 608 exam as well as R 410A refrigerant safety.

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 and comfort, electricity and motors will be covered in this extensive course.

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