1. Missouri HVAC Contractor Licensing — Local (No Statewide License)

   Missouri has no statewide HVAC/mechanical contractor license — the Division of Professional Registration issues none, and the proposed Statewide Mechanical Contractor Licensing Act has not been enacted (still a pending bill as of 2026). Licensing is municipal/county: Kansas City, St. Louis City/County, Springfield, Liberty, and most KC-metro cities run their own mechanical contractor licenses — apply in each jurisdiction where you work. EPA Section 608 certification for refrigerant handling is a separate federal requirement.
