HVAC Fundamentals - HVAC1
This is a one-credit course that introduces students to the basic knowledge and skills regarding
electrical theory, circuitry, and computers as they relate to heating, ventilation, air-conditioning, and
refrigeration (HVACR). Emphasis is placed on safety and basic concepts of electrical circuits.
Students learn to systematically troubleshoot circuits by interpreting wiring diagrams. Students
enrolled in this course display competence in reading, writing, and mathematics skills as well as
problem-solving techniques. Students exhibit basic competencies in physical science as it relates to
electricity and are able to comprehend both verbal and written instruction. Instruction in this course
consists of both individual and group classroom and laboratory activities. Upon successful
completion of this course, students demonstrate basic understanding of safety, electrical terms,
symbols, laws, and circuit testing instruments. This course is a prerequisite to HVACR Electrical
Components and Controls.
Career and technical student organizations are integral, cocurricular components of each career and
technical education course. These organizations serve as a means to enhance classroom instruction
while helping students develop leadership abilities, expand workplace-readiness skills, and broaden
opportunities for personal and professional growth.
Students will:
1. Demonstrate safety rules, regulations, and procedures when working with electrical systems.
2. Demonstrate use of hand tools and power tools related to HVACR systems.
3. Use various meters to measure electrical values.
Examples: analog, digital
4. Demonstrate the use of Ohm’s law and Joule’s law.
5. Demonstrate procedures for testing fuses and capacitors.
6. Demonstrate procedures for building series, parallel, and series-parallel circuits.
7. Determine the functional condition of motor windings in a single-phase compressor.
8. Demonstrate testing procedures for electrical components, including fan relays, contactor
relays, capacitors, and motor windings.
9. Determine procedures for measuring heat anticipator amperes.
10. Demonstrate procedures for installing heating and cooling thermostats.
11. Explain conductors, insulators, and related symbols used in HVACR.
12. Demonstrate procedures for making proper electrical connections.
13. Explain various types of wiring diagrams, including pictorial, line, and schematic used in
HVACR.
