About this course

Independent GCHS training

Each lesson has a dimensioned diagram, a glossary, 14 practice questions (20 in Lesson 13) and neural narration. Numbers were checked against at least two public sources. Texas cities adopt their own code editions and local amendments, HVAC work is done by TDLR-licensed contractors, and gas piping and water heaters by licensed plumbers, so always confirm the edition and amendments in force where the work is permitted. This is training, not a substitute for the adopted code.
