Arkansas HVAC Legislation, Codes, and Guidelines
Arkansas HVAC Building Codes and Legislation
The state of Arkansas has adopted the 2021 International Mechanical Code (IMC) to govern the design, installation, and maintenance of mechanical systems, including HVAC. This code is enforced to ensure the safety, efficiency, and performance of mechanical systems in both public and private facilities throughout the state.
Regulatory Oversight and Licensing
Regulatory oversight for HVAC contractors in Arkansas is provided by the Arkansas Department of Labor and Licensing through the HVAC/R Licensing Board. This board is responsible for licensing, examinations, continuing education requirements, and code enforcement. While entry-level HVAC technicians do not require a state license, they must register with the state and work under the supervision of a licensed HVAC contractor. Contractors must hold a valid state license, which is categorized into several classifications (Class A through E, and Class L) based on the scope of work permitted, such as system capacity and the type of services offered (e.g., installation, repair, or sheet metal work).
