HVAC Technician vs Plumber: which is more exposed to AI?

Effectively tied: 4 points separate HVAC Technicians from Plumbers.

HVAC Technician scores 20% time-weighted AI exposure and Plumber scores 16% — close enough that the headline number tells you almost nothing. The difference lives underneath it: HVAC Technicians lose the most ground on "look up specs and manuals" (80%), while for Plumbers it is "read and interpret plumbing plans" (44%). Both roles sit inside Trades & Construction, so the exposure difference reflects task design rather than a change of field.
