1. Alabama Department of Revenue - Sales Tax License

   Required for businesses making retail sales of tangible personal property in Alabama. Alabama sales tax is a privilege tax on retail sales; most services are not taxable, so service-only businesses may not need to register. Local city and county sales taxes are also due on top of the state rate and vary by jurisdiction - use ADOR's local tax rate lookup for your address. Register with the Alabama Department of Revenue via My Alabama Taxes (MAT); state and local returns are filed together through ONE SPOT.

2. EPA Section 608 Technician Certification (for refrigerant handling)

   Federal law under Clean Air Act Section 608 requires technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants to be certified, and prohibits knowingly venting refrigerants. Certification is by type: Type I (small appliances), Type II (high-pressure), Type III (low-pressure) and Universal, each requiring the Core section plus the type-specific section. Testing is conducted by EPA-approved certifying organizations, and certification does not expire.

1. Alabama Licensing Board for General Contractors (Mechanical classification) - required only for projects $100,000 or more

   Alabama has no statewide HVAC-specific contractor license; the Alabama Electrical Contractors Board licenses only electrical contractors and journeyman electricians. HVAC/mechanical contractors bidding or performing work valued at $100,000 or more (labor plus materials) must be licensed by the Alabama Licensing Board for General Contractors under the Mechanical classification and pass the Business & Law exam. Below that threshold no state contractor license applies - only local business licensing and EPA Section 608 certification for refrigerant handling.
