Flue Liner Installer (Mid-Level) vs Ventilation Hygiene Engineer (Mid-Level)

How do Flue Liner Installer (Mid-Level) and Ventilation Hygiene Engineer (Mid-Level) compare on AI displacement risk? Flue Liner Installer (Mid-Level) scores 70.7/100 (GREEN (Stable)) while Ventilation Hygiene Engineer (Mid-Level) scores 61.4/100 (GREEN (Transforming)). Here's the full breakdown.

Flue Liner Installer (Mid-Level): Hands-on chimney lining work in unstructured domestic environments — every chimney is different. Working at height, lowering liners through irregular masonry, connecting in cramped fireplace openings. No robotic pathway exists. Safe for 5+ years.

Ventilation Hygiene Engineer (Mid-Level): Physical ductwork cleaning in ceiling voids, risers, and commercial kitchens protects this role for decades. AI is reshaping reporting and IAQ data analysis, but crawling through ductwork to clean it to TR19 standard remains irreducibly human. Safe for 5+ years.

What Do These Scores Mean?

Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).

Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk). For full individual assessments, see the Flue Liner Installer (Mid-Level) and Ventilation Hygiene Engineer (Mid-Level) role pages.
