How to become an HVAC technician in Louisiana

The path in Louisiana, step by step

Louisiana licenses some HVAC work at the state level and leaves the rest to cities or to no one. A license is needed when a mechanical job is worth more than $10,000, counting labor and materials. Jobs of $10,000 or less do not need this state license.

1. Confirm your jobs will run over $10,000 and pick the Mechanical (6) or HVAC (6.1) classification.
2. Name a qualifying party for the business who will take the course and exam.
3. Complete the LSLBC Business and Law course.
4. Wait for the PSI eligibility letter, then pass the trade exam for your classification.
5. Prepare a financial statement showing at least $50,000 net worth.
6. Apply online through the LSLBC portal and pay the fees.
7. Renew before expiration, choosing a one, two or three year term.

Finding an apprenticeship in Louisiana

Louisiana runs Registered Apprenticeship through its own State Apprenticeship Agency, recognized by the U.S. Department of Labor to register and oversee programs there. Its staff are state employees, and it may use the federal paperwork or forms of its own. Apprenticeship.gov lists the Louisiana State Apprenticeship Agency as the contact.

Either way, a registered program means paid work with a mentor, raises as you progress, classroom instruction and a credential recognized in every state. Search open spots in the Apprenticeship Job Finder.

Across the country. Some technicians train through an apprenticeship, which usually lasts several years. Each year mixes paid on-the-job training with some classroom work on safety, blueprint reading, and heating and cooling systems.
