The verdict

HVAC Concepts runs at 25% of its industry's injury rate - far safer than the typical HVAC (heating, ventilation and air-conditioning) contractors workplace, earning a grade A.

HVAC Concepts: 0.7 TCR = 25% of HVAC (heating, ventilation and air-conditioning) contractors BLS 2.8 · 2y Form 300A (see methodology below)

HVAC Concepts safety composite

HVAC Concepts scores strongest on total case rate (tcr) (safer than 93% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
