Do HVAC contractors need a license in Louisiana?
Yes. In Louisiana, air conditioning, refrigeration, heating or ventilation work on a project worth $10,000 or more must be done by a mechanical contractor licensed by the State Licensing Board for Contractors. Mechanical is one of the board’s major license classifications, and a licensee may bid or perform only work within the classification on its license. The mechanical-contractor definition does not limit what a licensed general or residential contractor may do. Employees of a licensee are exempt, as are owners who supervise work on their own personal residence (no more than one residence a year). This is La. R.S. 37:2150.1, 37:2156, 37:2156.1, 37:2157, 37:2163.
