Service Core Program

Service Core Program

The HVACR Service Core program is a comprehensive HVACR education program encompassing heating, ventilation, air conditioning, and refrigeration.  It is specifically structured to enrich the skills of installers and technicians who are:

  • Just beginning in the HVACR industry
  • Continuing education for upgrading knowledge and skills, or
  • Preparing for certifications or licenses (NATE or ICE)

The content presented in each course focuses on learning objectives that have been identified by HVACR industry groups (ARI, NATE, RSES, ACCA, and PAHRA) as key knowledge for an HVAC/R technician. 

This program is offered completely online and consists of one (1) math review and eight (8) courses in a specific educational sequence that fulfill the 160 hours needed for the HVACR Service Core Certificate.  Even though it is self-paced, students receive a 60 day subscription for each course.  Students are registered for one course at a time in a specific sequence. Upon successful completion of each course (a score of 75% or higher), students are registered into the next course and receive a certificate of completion for the completed course.  After successful completion of the math review and eight courses students receive a Certificate of Completion for the Service Core Program.

The courses making up the Service Core Program are:

R.  050 Applied Math Review

Add, Subtract, Multiply and Divide.  These four functions of mathematics are critical to the HVACR workplace. This course is designed to exercise your ability to perform these four functions using whole numbers, fractions and decimals utilizing scenarios from the HVACR workplace.

Each module provides a tutorial that demonstrates how the specific process is performed and then followed with a selection of exercises to sharpen your skills.  The correct answer is given after each of the exercise problems. The module is completed with a 10 randomly selected question exam.  You will have 5 attempts at each exam to master math process assessed.  Your highest score will be entered in your grade book.

Module 4: Capacitance (electrons stored and ready)
Module 5: Inductive Reactance (working against itself)
Module 6: Transformers (take it up or down)

5.  HVACR 113 Electrical Common Components

Electrical 113 covers basic control components found in HVAC/R systems, a logical continuation of the 112 course. Presentations and examples are given for specific devices and their electrical sequence of operation in basic and not so basic HVAC/R applications. Technicians that have a good understanding of this content will be much more effective in a service job.

Module 1: Control Methods, Temperature & Pressures
Module 2: Residential Heat / Cool Thermostats @ Low Voltage
Module 3: Really Good Relay Stuff (A relay Olympic?)
Module 4: Contactors go / Starters go with protection
Module 5: Power wiring (~the hot stuff~)
Module 6: Chasing circuits with schematics

6.  HVACR 114 HVACR Electrical Motors

This online course is dedicated to common single-phase and small three-phase electric motors. Presentations focus on basic motor theory, common types of motors, starting components and protection devices. We will also develop diagnostic skills for motor troubleshooting and replacement. Instruction aligns with ANSI/ACCA Quality Installation & Maintenance Standards. This course is NATE recognized for 18 hours of continuing education (CEHs) applicable to NATE recertification, and BPI recognized for 9 continuing education units (CEUs). Six modules cover:

8.  HVACR 141 Refrigeration I

Refrigeration 1 is designed to provide a thorough examination of the refrigerant circuit as it is applied to both air conditioning and refrigeration purposes, and to provide a practical and systematic method to diagnose problems in the refrigerant circuit. While there are many different brands of equipment in the market, the rules of operation (laws of physics) governing them are the same. If you understand the parameters governing the operation of the refrigerant circuit, you will be able to diagnose any piece of equipment. Since the text book does an excellent job of covering refrigeration applications, the online material will put more emphasis on the refrigerant circuit in air conditioning equipment.
