You’ve Got the Foundation. Now Build the Skills That Get You on Service Calls.
Level 1 gave you the fundamentals. Level 2 is where you start developing the technical depth that employers actually need on job sites — advanced systems knowledge, real electrical competency, and the field math that makes installation and service work accurate and efficient.
This level is designed for technicians who have completed Level 1 and are ready to move beyond component identification into hands-on diagnostic and installation knowledge.
Is Level 2 Right for You?
This course is the right fit if you:
- Have completed Residential HVAC Technician Level 1 (required prerequisite)
- Are working in the field and need to advance beyond entry-level tasks
- Want to demonstrate to your employer that your skills are progressing on a documented path
- Are preparing for Level 3 and the full Master Residential HVAC Technician Certificate
What You’ll Learn — Five Complete Courses
Each topic below is a standalone course. Work through them in order as assigned in your Learning Pathway:
- Advanced Math for HVAC — Field calculations for installation and service personnel, including load math, unit conversions, and measurement accuracy
- Advanced HVAC Systems and Components — A deeper dive into how residential systems are engineered and how components interact under real operating conditions
- On-the-Job Safety — Level 2 — Safety protocols specific to installers and intermediate technicians working on live systems and in confined or elevated spaces
- Electrical Fundamentals — The electrical theory behind HVAC diagnostics — circuits, loads, meters, and reading schematics
- HVAC Electrical Controls — Thermostats, contactors, relays, sequencers, and control boards — how they work and how to diagnose them
What You Receive Upon Completion
After passing all five courses, you’ll receive your Residential HVAC Technician Level 2 Certificate of Completion — documentation that your training has advanced to the intermediate level, ready to show any employer or client.
One More Level to Go
Level 2 is the second of three sequential courses in the Residential HVAC Technician program. Level 3 completes the series with advanced refrigeration diagnosis and airflow — the skills that round out a fully capable residential technician.
For maximum savings, consider the complete three-level bundle, which includes Levels 1, 2, and 3 at a significant discount.

Frequently Asked Questions
What are the prerequisites for Residential HVAC Technician Level 2? +
Residential HVAC Technician Level 1 must be completed before enrolling in Level 2. Level 1 covers the foundational knowledge — system fundamentals, basic refrigeration, electrical science, and safety — that Level 2 builds directly upon.
How many courses are included in Level 2 and what do they cover? +
Level 2 consists of five complete courses: Advanced Math for HVAC, Advanced HVAC Systems and Components, On-the-Job Safety for Level 2 Technicians, Electrical Fundamentals, and HVAC Electrical Controls. Each is a standalone course completed in the order assigned in the Learning Pathway.
What certificate is awarded upon completing Level 2? +
Upon passing all five Level 2 courses, students receive the Residential HVAC Technician Level 2 Certificate of Completion. This documents intermediate-level training to a defined standard and can be presented to employers as proof of advancing technical competency.
Is this course manufacturer-specific? +
No. Like all eTech programs, Level 2 is completely manufacturer-agnostic. The electrical, systems, and safety content applies across all residential HVAC equipment brands. Training was developed by a Certified Master HVACR Educator (CMHE, NATE) with more than 50 years of field experience.
Can employers enroll technicians in Level 2 directly without Level 1? +
Level 1 is a required prerequisite for Level 2. Employers onboarding technicians without prior formal training should start them at Level 1 first. Contractors looking to enroll teams across multiple levels can contact eTech directly to discuss group enrollment and sequencing options.
Does Level 2 lead to further certification? +
Yes. Level 2 is the second of three sequential courses. Level 3 completes the program with advanced refrigeration diagnosis and airflow, after which technicians qualify for the Master Residential HVAC Technician Certificate. All three levels are available together as a discounted bundle.
