Advanced Gas Heating Diagnostics Course 

 

The Advanced Gas Heating Diagnostics Course at ITEC Training & Education Center is designed for working HVAC technicians who already understand the fundamentals and want to sharpen their edge. This is not a classroom-only course; it’s an advanced, hands-on experience held inside ITEC’s fully equipped 20,000-square-foot technical lab.

By the end of the course, you’ll know how to pinpoint hard-to-find problems, verify system efficiency, and restore heating performance with confidence and precision.

Why Take the Advanced Gas Heating Diagnostics Course

When you’re called to a home or job site in the middle of winter, there’s no room for guesswork. Advanced diagnostics skills separate technicians who replace parts from those who solve problems.

This course helps you:

• Master deep-dive diagnostics: Learn how to interpret flame signals, gas pressures, venting airflow, and sequence of operation to isolate the true cause of heating issues.
• Boost efficiency and accuracy: Improve your ability to balance combustion, fine-tune gas input, and verify safe operation.
• Grow your credentials: Completing this program strengthens your path toward advanced NATE or ESCO certifications and shows employers that you’re serious about your craft.
• Advance your career: Field experience is valuable, but pairing it with formal, lab-tested training helps technicians move into senior or lead service roles faster.

What You’ll Learn

You won’t be watching slides, you’ll be diagnosing live systems. Each lab module is designed to simulate a real-world heating call with layered faults and performance variables.

Key topics include:

• Combustion and ignition analysis: Flame rectification, pilot vs. hot surface ignition, flame sensor testing, and verifying proper gas pressure.
• Vent and airflow problems: Diagnosing flue draft issues, rollout switch trips, and inadequate combustion air.
• Electrical and control diagnostics: Using multimeters and manometers to test transformers, control boards, relays, and safety switches.
• System efficiency tuning: Performing combustion analysis to improve performance and reduce call-backs.
• Code and safety standards: NFPA and manufacturer-specific requirements for gas appliances.

Each session includes instructor-led demonstrations, supervised hands-on practice, and independent troubleshooting exercises with immediate feedback.

Tools Required

Because this course mirrors field conditions, all participants must bring their own professional tools, including:

• Digital multimeter with microamp capability
• Manometer (digital or analog)
• Combustion analyzer
• Standard HVAC hand tools (screwdrivers, nut drivers, wrenches, etc.)

Technicians who arrive prepared get the most out of every lab session. A full tool checklist is provided after registration.

Certifications

Successful completion of this course qualifies students for the following credentials:

• ITEC Gas Heat 2 (Service)
• NATE Gas Heating Service ($140 Core Exam required)
• ESCO Gas Heat Certification ($35 Core Exam required)

These nationally recognized certifications validate your mastery of advanced diagnostic skills, system safety, and professional service standards—helping you stand out to employers and customers alike.

Prerequisite

Enrollment in this course requires one of the following:

• Successful completion of ITEC Gas Heat 1 and ITEC Electric 1, or
• A passing score on the ESCO Employment Ready Gas Heating Exam (open or closed book; $15 fee applies).

This ensures every participant begins with a solid foundation in electrical and gas heating fundamentals before advancing to complex diagnostics.
