How HVAC replacement costs vary in Montana
State-specific code or insurance rule: Montana has no statewide HVAC contractor license, but Montana Department of Labor & Industry registers any contractor doing work over $2,500 — a uniquely low threshold that pulls residential HVAC change-out into the registered-contractor framework even in unlicensed municipalities.
