What license tiers does Louisiana offer?
Louisiana licenses the business, not the worker: the statewide mechanical contractor license from the LSLBC governs commercial work at $10,000 and above, residential work runs on separate registration thresholds we flag for verification, and technicians carry no state credential at all. Municipalities, New Orleans most prominently, add their own registrations on top.
What is the Louisiana HVAC exam like?
Two exams stand between you and the LSLBC license: the mechanical trade exam covering the systems themselves, and the Business and Law exam covering contracting practice, lien law, and finances. The Board also runs a financial stability review, so the application is as much documentation as examination.
How much does an HVAC license cost in Louisiana?
Published figures put the state side at roughly $275 to $475 covering application and both exams, plus insurance. There is no technician-side cost at all beyond EPA 608, and the experience you build before licensing is paid work under someone else's license.

What most guides get wrong about Louisiana
Louisiana's quiet distinction is the financial stability review: unlike states that only test trade knowledge, the LSLBC examines your finances before licensing you, which means bookkeeping, not brazing, is what delays most applications. Get the financial documentation assembled before you schedule either exam.
Louisiana HVAC license: frequently asked questions
Do you need a license to do HVAC work in Louisiana?
Not as a technician: Louisiana has no state technician license, and you work legally under a licensed mechanical contractor with EPA 608. The license question arrives when you contract: commercial mechanical work at $10,000 and above requires the statewide LSLBC mechanical contractor license.
What does the Louisiana contractor license require?
Two exams, the mechanical trade exam and a separate Business and Law exam, plus a financial stability review the Board conducts on every applicant, insurance, and $275 to $475 in published application costs, with processing typically running 8 to 12 weeks.
What about residential HVAC work in Louisiana?
Residential runs on its own thresholds: published guides describe home improvement registration for mid-range jobs and a residential contractor license above $75,000, and we flag the exact band for verification against the LSLBC's current rules. Replacement-and-service shops should confirm where their typical ticket lands before assuming an exemption.
Do Louisiana cities add their own requirements?
Yes, and it is the trap out-of-parish contractors hit: New Orleans and other municipalities layer local registration on top of the state license. The LSLBC license is necessary but not always sufficient; check the city where the job site sits, not where your shop is.
