Gas Technician 3 Pre-Exam


Gas Technician is the “H” in HVAC. There are 3 main levels of Gas Technician licensing (G3, G2, G1). The equipment you can work on includes furnaces, water heaters, stoves, clothes dryers, pool heaters, fireplaces, and many more. This includes residential, commercial, and industrial.

This course contains a quick review of the G3 modules 1 to 9 and the applicable codes, acts and regulations. It contains no practical training and is a theory-only review course. This course prepares students with experience working in the field and wishing to challenge the G3 certification of qualification exam for their exam. It is also a good refresher course for students who have taken a full course previously and are struggling to pass the certification of qualification exam.
