How to Start an HVAC Business in Louisiana (Step by Step)

Step 1: Understand Louisiana HVAC Licensing Requirements

Louisiana requires an HVAC contractor license from the Louisiana State Licensing Board for Contractors (LSLBC) for any work exceeding $10,000 in aggregate contract price (including labor and materials). If you only perform work under $10,000 per contract, you do not need a state contractor license, but you may still need local parish or city licenses.

HVAC Contractor License requirements:

Age 18 or older
Valid Social Security Number or Federal Tax ID
Formal apprenticeship program OR associate degree in HVAC technology
Financial statement showing net worth of at least $50,000
Pass both the HVAC Mechanical Trade Exam and the Business & Law Exam

License classification: HVAC work falls under the Mechanical or Sheet Metal classifications. Review LSLBC classification definitions to determine which applies to your business scope.

Step 2: Meet Experience and Education Requirements

Before applying for a contractor license, you must demonstrate technical knowledge through one of these paths:

Option 1: Formal apprenticeship program

Complete a registered apprenticeship program through the Louisiana Workforce Commission or a national program (such as HVAC Excellence or NCCER)
Typically 3-5 years of combined classroom instruction and on-the-job training
Provides documented proof of training for LSLBC application

Option 2: Associate degree in HVAC

Earn an Associate of Applied Science (AAS) degree in HVAC Technology from an accredited institution
Most programs take 18-24 months to complete
Provides both technical training and academic credentials

Step 3: Get EPA 608 Certification

All HVAC technicians who work with refrigerants must obtain EPA Section 608 Certification. This is a federal requirement, not state-specific:

Type I: Small appliances (refrigerators, window AC units)
Type II: High-pressure equipment (commercial AC, heat pumps)
Type III: Low-pressure equipment (chillers, large commercial systems)
Universal: All three types (recommended for HVAC contractors)

Cost: $20-$150 depending on testing organization and certification type.

Where to test: ESCO Institute, HVAC Excellence, and other EPA-approved testing organizations offer online and in-person exams.

Step 4: Form Your Business Entity

Form an LLC to protect your personal assets from business liabilities:

File Articles of Organization with the Louisiana Secretary of State through the GeauxBiz portal
Choose a business name that includes “LLC”
Designate a registered agent with a physical Louisiana address
Pay the $100 filing fee
File an Annual Report each year by your formation anniversary date ($30 fee)

Step 5: Prepare Financial Documentation

The LSLBC requires proof of financial responsibility to ensure contractors can complete projects and meet obligations:

Obtain a financial statement from a Certified Public Accountant (CPA) showing a net worth of at least $50,000
Net worth includes assets minus liabilities (business and personal combined)
The financial statement must be dated within 90 days of your application

Step 6: Apply for Your HVAC Contractor License

Submit your application to the Louisiana State Licensing Board for Contractors:

Complete the online application at lslbc.louisiana.gov
Contact: 225-765-2301
Provide proof of apprenticeship or associate degree
Submit financial statement showing $50,000+ net worth
Pay the $450 initial application fee
Once your qualifications are approved, you’ll be authorized to schedule your exams

Step 7: Pass the Trade Exam and Business & Law Exam

HVAC Mechanical Trade Exam:

100 multiple-choice questions
Covers HVAC installation, repair, maintenance, electrical systems, refrigeration, ventilation, and safety
Exam fee: $120
Passing score: 70% or higher
Open-book exam (you can bring reference materials)

Business & Law Exam:

80 multiple-choice questions
Covers Louisiana contractor laws, business management, accounting, contracts, liens, and regulations
Exam fee: $120
Passing score: 70% or higher
Open-book exam

Tip: Study materials and exam prep courses are available through LSLBC-approved providers and trade associations.

Step 8: Receive Your License and Maintain Renewal

Once you pass both exams, the LSLBC will issue your contractor license:

License is valid through December 31 of each year
Annual renewal required by December 31 (late renewals incur penalties)
Renewal fee varies based on license classification
No continuing education required for general renewal, but may be required for certain classifications

Step 9: Get Local Business Licenses

In addition to your state contractor license, most parishes and cities require local business licenses:

Contact your parish clerk’s office or city hall
Fees typically range from $50 to $200
Some parishes may require proof of insurance or state license before issuing a local license

Step 10: Get Business Insurance

General liability insurance: Protects your business from claims of property damage or bodily injury. Recommended coverage: $1-2 million. Annual cost: $1,200-$3,000.

Workers’ compensation insurance: Required if you have even one employee. Louisiana law mandates workers’ comp for all businesses with employees.

Commercial auto insurance: Required if you use vehicles for business purposes (transporting equipment and tools).

Contractor’s tools and equipment insurance: Covers theft or damage to HVAC tools, ladders, and equipment.
