State License Jobs in St. Louis, MO

State licensing requirements for HVAC technicians vary considerably by state, but in St. Louis, MO, working without the appropriate license exposes both the technician and the employer to penalties and liability. Most states require a journeyman or mechanic license for field work and a contractor or master license to pull permits and run a business. Employers listing state license as a requirement are signaling they need someone who can operate independently without supervision from a licensed holder.

In most states, the path to licensure involves a combination of verified work experience (typically two to four years for journeyman, four to six for contractor) and passing a trade exam. Missouri applicants should check the specific hours and exam requirements with the state licensing board, as reciprocity agreements with neighboring states vary. Technicians holding a valid license from one state who are relocating to Missouri should investigate reciprocity early in their job search — some states fast-track applications from licensed holders in reciprocal states.
