Class Overview

In North America gas heating furnaces are the most common type of residential and light commercial heating system. In this course, you’ll learn how to install, troubleshoot, service, and maintain gas furnaces—professionally, accurately, and quickly. The equipment covered in this class ranges from standard efficiency furnaces to the latest multi-poise condensing furnaces with modulating gas valves, variable speed motors, microprocessor controls, electronic thermostats, and direct ignition burners with flame rectification proving circuits. Classroom sessions cover: gas heating fundamentals, types of gas heating systems, furnace construction, operating components and safety controls, furnace combustion and venting air requirements, installation rules and gas pipe sizing, determining proper size for vent pipe and venting concerns, conversion of natural gas to LP, adjustments for altitude, accessories (such as humidifiers and electronic air cleaners), reading electrical schematics and interpretation of various heating electrical circuits. Classroom instruction is reinforced with a number of lab troubleshooting exercises on operating rooftops and residential furnaces, with 30% to 40% lab time.

Upon request, the EPA 508 certification can be held after class at a slight additional cost. This certification is required to handle refrigerants.

Who should attend this training

This course is for HVAC technicians with a minimum of one year of field experience or a graduate of an HVAC training program. Students are expected to have basic math skills and a basic understanding of HVAC tools (gages and digital thermometers) and troubleshooting equipment.

HVAC Training Objectives

Learning Objectives

At the conclusion of this course each student should be able to:

  • Measure gas pressure and set up a furnace for proper firing rate
  • Measure and adjust blower airflow
  • Measure inducer air pressure and evaluate operation
  • Read and interpret various furnace wiring diagrams
  • Electrically troubleshoot furnace electrical circuits and components
  • Determine proper air vent and gas pipe size
  • Understand how furnace accessories such as humidifiers and electronic air cleaners work

Learning Methods Used

This course uses a combination of classroom lecture, videos, animations, tours in the training facility lab, demonstrations, practical labs on operating equipment and workshops to present the material. Student’s achievement of the learning objectives is determined by successful completion of the workshops, labs, homework, and final written and practical exam. Workshops are instructor guided exercises using the procedures taught in the lectures.

Prerequisite requirements


Suggested Background

For technicians just entering the HVAC field or persons with no field experience, this course is most effective when preceded by the BASIC Program (SER400), which introduces participants to fundamental concepts of both air conditioning and heating systems, including lab time with service test equipment and tools.

Materials to bring

No special equipment is required we provide the appropriate safety equipment required by Carrier. Arc flash equipment is not required for the voltages used in the lab, if you are required by your company to use other PPE you may bring that to class.

What you will receive

Students in this course receive a course workbook, Carrier Service Procedures handbook, safety gloves and goggles, charging calculators, and PT cards.

Appropriate dress for this class

This class has a number of exercises that take place in the lab on operating units; participants should wear long pants, closed toed shoes and appropriate shirt, long or short sleeve. If your employer requires special dress which is more stringent than these requirements, this dress should be worn.

Class hours

Class starts at 8 AM Monday and runs from 8 AM till 5 PM each day including Friday. Travel arrangements should be made accordingly.
