HVAC licenses in Louisiana
HVAC contractors are licensed by the state.
Who licenses: Louisiana State Licensing Board for Contractors (LSLBC)
License types: Commercial License (Mechanical classification: Heat, Air Conditioning, Ventilation, Duct Work, and Refrigeration).
Companies: A contractor must hold an LSLBC Commercial License in the Mechanical classification (subclassification Heat, Air Conditioning, Ventilation, Duct Work, and Refrigeration) when an air conditioning, refrigeration or heating job costs more than $10,000 including labor and materials, under R.S. 37:2150.1 et seq. (the Contractors Licensing Law). Smaller jobs fall below the state threshold, and the LSLBC pages we read do not say whether any other state license applies to them.
Local rules: Local building permit officials must see proof of the applicant's LSLBC license before issuing a permit (R.S. 37:2160), and licensed mechanical contractors are excluded from local examination (R.S. 37:2156.1); We did not verify rules for jobs under $10,000.
Check a license: arlspublic.lslbc.louisiana.gov
Look the company up on the LSLBC license search and confirm it holds a Commercial license with the Mechanical classification before agreeing to work over $10,000.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Keeping cool in New Orleans
