How to get licensed
- 1
Meet the prerequisites
Meet the eligibility requirements set by the issuing board. No statewide prerequisites exist for HVAC/mechanical work in Missouri because there is no statewide license. Federal EPA Section 608 certification (for handling refrigerants) applies nationwide, including Missouri, but is a federal — not a Missouri state — requirement. Local jurisdictions that license mechanical contractors set their own eligibility rules. [1]

Complete approved training
Complete the required training. Missouri has no statewide license, board, or training-hour requirement for HVAC/mechanical technicians or contractors. The Division of Professional Registration's full list of 41 boards (accountancy, electrical contractors, cosmetology, etc.) includes an Electrical Contractors board but no mechanical/HVAC board. A bill to create a 'Missouri Statewide Mechanical Contractor Licensing Act' (most recently SB 392/SB 957 and HB 2659 in the 2026 session; earlier versions include SB 31, SB 1487, SB 80, SB 559, SB 11 dating back to 2018) has been introduced in nearly every session since 2018 but has never passed — the 2025 version died without a floor vote. Individual cities and counties (e.g. Kansas City, St. Louis County, Springfield) issue their own local mechanical/HVAC contractor licenses with their own training/experience requirements, but these vary by jurisdiction and are outside any statewide structure.

No statewide HVAC/mechanical license exists, so there is no state application, license, or renewal fee. Any license or permit fees for HVAC/mechanical work are set locally by individual cities and counties, not the state.
Renewal & continuing education
Renewal cycle not specified.
No statewide license means no statewide renewal cycle or continuing-education requirement. Renewal terms for HVAC/mechanical licenses, where a local jurisdiction requires one, are set by that city or county.
Reciprocity
No reciprocity or endorsement route was found.
Not applicable — there is no statewide Missouri HVAC/mechanical license to reciprocate into or out of. No interstate compact covers HVAC/mechanical licensing.

Frequently asked questions
Does Missouri require a state HVAC license?
No. Missouri's Division of Professional Registration licenses Electrical Contractors at the state level, but has no board or license for HVAC/mechanical contractors or technicians statewide.
Is a statewide Missouri HVAC license coming?
A bill to create one — the 'Missouri Statewide Mechanical Contractor Licensing Act' — has been introduced in nearly every legislative session since 2018 (most recently SB 392, SB 957, and HB 2659 in 2026), but it has never passed. Until it does, HVAC licensing remains local-only.
How is HVAC work regulated in Missouri, then?
Regulation happens at the city/county level. Jurisdictions such as Kansas City, St. Louis County, and Springfield each issue their own local mechanical/HVAC contractor licenses with their own requirements; many smaller jurisdictions have no local licensing requirement at all.
Do Missouri HVAC technicians need any certification?
The federal EPA Section 608 certification is required nationwide (including Missouri) for anyone who handles refrigerants, but this is a federal requirement, not a Missouri state license.
Is there a Missouri state exam for HVAC work?
No — since there is no statewide HVAC license, there is no associated statewide exam. Any exam or competency requirement would be set by a local licensing jurisdiction, if one exists.
