Do HVAC contractors need a license in Mississippi?
Yes. In Mississippi, any subcontractor doing mechanical or heating, ventilation or air-conditioning work on a residential construction or residential improvement project must be licensed annually by the State Board of Contractors, whatever the dollar amount of the subcontract. Residential construction and residential improvement are defined by reference to a residential builder’s project costing more than $50,000 and a remodeler’s improvements to an existing home costing more than $10,000. On other private and public projects, a prime contractor or subcontractor whose contract is $50,000 or more must hold a certificate of responsibility from the State Board of Contractors, and a contract awarded to a contractor without one is void. This is Miss. Code §§ 73-59-3, 73-59-1, 31-3-15, 31-3-1.
