HVAC Service Technician Level 1 & 2
This is an introductory course, designed to prepare the student for an occupation in the air conditioning and refrigeration trade. These classes can be completed separately over two semesters or taken as a combined class (when offered) within one semester. Level I must be successfully completed before taking Level II.
Level I includes:
- Introduction to Refrigeration, including: heat transfer, refrigeration components, refrigeration tools, operation of a walk-in cooler, compressor troubleshooting and replacement.
- HVAC Electricity, including: ohms, amps and volts, Ohms Law, basic wiring diagrams and symbols, control circuits, and understanding schematics.
- Oil, Gas and Electric Furnaces, including: fuel oil properties, oil burners, furnace operation and repair, natural/LP gas properties, gas burners, gas furnace operation and repair.
- Heat Pump Service, including: heat pump cycle, components, troubleshooting, understanding sub-cooling, super heat, and using heat pump charging charts.
Level II includes:
- Mechanical Cooling, including: refrigeration cycle, refrigerant charging, load calculation and duct design.
- PLC’s / CFC, including: digital logic, input/output, CPU operation, ladder logic basics, and CFC Certification
- HVAC Controls, including: electric controls, pneumatic controls, mechanical refrigeration controls (metering devices), electronic control boards, and thermostats.
- HVAC troubleshooting, including: pressure-temperature chart and refrigerants. Students will also be using diagrams for troubleshooting.
An HVAC service tech would be expected to handle the following repairs:
- Repair and installation of air conditioning and refrigeration equipment and systems
- Mechanical system troubleshooting using various tools and test instruments
- Perform routine preventative maintenance of refrigeration and A/C equipment and systems
- Repair and maintenance of both commercial and residential systems
HVAC service techs are employed by air conditioning and refrigeration contractors, repair facilities, hospitals, factories, apartment complexes and other maintenance companies.
Core topics include:
- HVAC theory
- HVAC Electricity
- Operation of Oil, Gas and Electrical Furnaces
- Heat Pump Service
- CFC Certification
- HVAC Controls and Troubleshooting
Through classroom lecture and hands on lab work, the student will learn the safe and practical applications of HVAC repair and service. Training sessions are held in a technical skills lab/classroom. The lab is equipped with the necessary supplies and tools to allow students to run refrigerant piping circuits and do rough in type installations. Students will work on HVAC and refrigeration systems supplied in the lab.
Should have the ability to work in a team environment, be organized, detail-oriented and a problem solver.

Technical Standards for Economic Workforce Development: Heating, Ventilation and Air Conditioning (HVAC)
Our program technical standards have been developed to help students understand nonacademic standards, skills, and performance requirements expected of a student in order to complete this particular curriculum.
If an accommodation is necessary to participate in the program, it is imperative to identify a reasonable accommodation to those students who qualify under the Americans with Disabilities Act (ADA). Reasonableness is determined by Accessibility Resources and the program on a case-by-case basis utilizing the program technical standards. The accommodation needs to be in place prior to the start of the program, or it may delay your ability to start the program. It is the student’s responsibility to contact Accessibility Resources and request accommodations.
