Requirements, license levels, and the issuing authority, sourced from Louisiana's official board.
Authority confirmed from official LSLBC site; mechanical classification and $10,000 threshold are established by LSLBC. EPA 608 required for refrigerants.
| Requirements | A mechanical license is required when the work value exceeds $10,000. Applicants generally need about 4 years of journeyman HVAC experience (or an HVAC AAS/technical degree), a financial statement showing net worth of at least $10,000, a designated qualifying party, and passing both a Trade exam and a Business & Law exam (70%), plus proof of insurance. |
| Reciprocity | Louisiana replaced state-by-state reciprocity with passed-exam recognition on October 23, 2024. In a letter to state regulatory agencies of that date, LSLBC Executive Director Brad Hassert wrote that going forward, if an applicant, licensee or registrant holds a classification that requires a test in any other state and has passed that test, with no waivers, exemptions or grandfathering in effect, the LSLBC will accept that passing exam for reciprocity; the exam will be accepted for the classification chosen by the LSLBC and will be equivalent in nature, and all other requirements for licensure must be met including investigation of all violations or pending violations. The letter states that this change in procedure renders any previous agreements null and void. There is therefore no current list of named reciprocal states for Louisiana, and any published list of Louisiana reciprocal states predating October 2024 is superseded. HVAC sits under LSLBC's Mechanical classification (with refrigeration, ductwork and pipefitting as related subclassifications), so mechanical and HVAC applicants come under this exam-recognition policy. Requests are made on LSLBC's reciprocity request form. |
| Renewal | Licensees choose a term of one, two or three years. The LSLBC Contractors Licensing Law and Rules and Regulations ('Blue Book') provides that licenses expire on the anniversary of the date on which the license was originally issued and that licensees shall elect upon renewal a one-, two- or three-year renewal term, up to a three-year maximum. A license becomes invalid on the last day of its term unless renewed; a 15-day grace period runs without penalty, after which a delinquent fee of up to $50 applies; a license left unrenewed for a full year from expiration is no longer eligible for renewal and the holder must reapply. Continuing education: none. Mechanical and HVAC work is licensed as a Mechanical classification under the Commercial contractor license (required once the work exceeds $10,000), and LSLBC states expressly that there are no continuing education requirements for commercial, mold, or home improvement contractors and registrants; the only continuing education mandate anywhere in the Blue Book is 6 hours per year for residential building contractors. Statutory maximum fees the board may charge: license fee up to $100, renewal fee up to $100, examination fee up to $50, delinquent fee up to $50. |
