Mainstream Heating & Cooling: 3.2 TCR = 115% of Plumbing and heating contractors BLS 2.8 · 2y Form 300A (see methodology below)

Mainstream Heating & Cooling safety composite

Mainstream Heating & Cooling scores strongest on total case rate (tcr) (safer than 51% of same-industry peers) and weakest on dart rate (safer than 11%), 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).
