What the Birmingham numbers change
Birmingham's modeled independent-shop midpoint is $143 per hour, $5 below the 50-metro median. Eight labor hours cost about $1,141 before parts, diagnostics or tax.
The dealer midpoint sits $46 higher per hour. A contract that caps reimbursement near the independent rate could leave a balance at a dealer even when the component itself is covered.
Birmingham records about 65 days at or above 90°F in a typical year. Heat exposure gives cooling and air-conditioning terms more relevance, although it does not create a model-specific failure rate.
