HVAC Training Curriculum
The HVAC program curriculum consists of comprehensive lessons that cover essential HVAC/R theory, typical HVAC systems and components used in residential and commercial buildings, as well as standard procedures for installing, troubleshooting and maintaining HVAC/R installations and commercial refrigeration. This is learning for the real world all in a convenient online course.
The goals and values of Ashworth College; time management; creating a realistic weekly and monthly study schedule; the nature and purpose of assessments; how to study effectively to prepare for and take an online examination; developing the skill sets necessary for success in the twenty-first century.
Summary of HVACR technology and employment in HVACR environments; professional organizations, certifications and professional work practices; safe work practices.
Review of common hand and power tools as applied to HVAC/R installation and servicing and an introduction to tools used exclusively by HVAC/R technicians, including electrical testing and HVAC/R servicing meters and gauges.
Overview of the standard components and assemblies that are used in the refrigeration process; identification of different types of refrigerants and the basic elements of the refrigeration cycle.
Covers the safe and environmentally correct practices of handling refrigerants, and the correct techniques and procedures for soldering, brazing, and installing piping and tubing. Students will also learn about system charging, evacuation and leak testing.
Covers safe work practices related to electricity, basic concepts of electricity and AC current theory, identification and application of common components found in HVAC/R systems, interpretation of diagrams and schematics and descriptions of modern control and communication systems.
Required concepts of air-conditioning theory including airflow and filtering principles, ventilation and dehumidification; installation practices for common residential AC systems and ductwork; troubleshooting and maintenance practices.
Safety considerations for working with combustible materials; overview of basic furnace design and principles, installation, troubleshooting and maintenance for both gas and oil-fired systems.
Overview of electric heating systems including installation, troubleshooting and maintenance; detailed coverage of heat pump designs including air-source and geothermal units; troubleshooting concepts for heat pump systems.
Explanation of basic construction elements and configurations; integration of green building principles in modern construction; overview of air quality and load calculations; duct design, zone control and system testing and correction.
Applications of HVAC concepts to commercial applications including coverage of rooftop units, chilled water systems and hydronic and boiler-based heating systems; students also learn about cooling towers and commercial control systems.
Detailed discussion of systems used for commercial food preservation and storage, complex installations for supermarkets, and large commercial ice machines. Includes troubleshooting practices for common commercial refrigeration installations.
Generally accepted practices for the proper installation, maintenance and troubleshooting of complex HVAC/R systems with detailed coverage of refrigeration system cleanup related to component failure.
The Heating and Air Conditioning program is a comprehensive collection of lessons that provide the knowledge necessary for students to understand HVAC/R theory, identify typical systems and components used for heating and air conditioning residential and commercial buildings, and understand the standard procedures for installation, troubleshooting and maintaining HVAC/R installations and commercial refrigeration. This program offers students the opportunity to complete the EPA 608 certification exam as offered by the ESCO Institute.
After completing the Heating and Air Conditioning program, students will be able to:
- Identify the common tools and work procedures required to work safely and effectively as heating and air conditioning technicians.
- Describe the basic theory of the refrigeration cycle and explain the basic scientific principles that apply to the refrigeration cycle.
- Identify standard refrigerants used in common commercial applications and the outline the accepted procedures for safe handling and disposal of common refrigerants.
- Describe the basic components present in heating and cooling systems and outline the standard techniques used to troubleshoot systems and identify faulty components.
- Identify the standard forms and functions of popular residential heating systems and describe the basic troubleshooting and repair procedures used for each.
