HVAC Apprentice Field Guide
An offline learning companion for supervised field work, from equipment to procedures.
The question
An apprentice in the field needs clear explanations that remain available without a connection, including when to stop and call the supervising technician.
The approach
Lessons, annotated equipment imagery, diagrams, a glossary, narration, and guided field mode are delivered from a shared web-content foundation.
Where it stands
The local field-review build contains 28 lessons and PWA/Android delivery paths.
The current boundary
The current build is not a published or certified training product. Field review and hardware narration verification remain open.
